MAIN PARTS DESCRIPTION

The mower is delivered equipped with a driveshaft and related operating manual.
When the machine is delivered, check that there is no damage to the mower or driveshaft. In case
of damage or missing parts immediately notify the Manufacturer or your Dealer.
Because of its size, the mower could be delivered with some parts disassembled. In this case, the
assembly of such parts is an owner's task, and must be carefully performed with reference to the
layout tables of the Spare parts section.
ATTENTION
For proper tightening torques of bolts and screws, refer to the section Torque values table of the
manual.
CONNECTING TO THE TRACTOR
The CMT mowers are designed to be mounted on tractors up to 50 hp equipped with 3-point Hitch
Category 1 (ISO 730 standard).
WARNING
Check the tractor PTO to ensure it is set at 540 rpm and turns clockwise.
WARNING
Before connecting the implement to the tractor, make sure that tractor and mower are on a flat,
stable and dry surface.
To connect the mower to the tractor the operator must do the following:
•Drive the tractor in reverse up to the mower, in order to slip the tractor hitch arms over the hitch
pins of the mower (see picture below).
8
SET UP

•Set the tractor's parking brake, stop engine, remove the ignition key and get off the tractor.
•Connect the lifting arms of the tractor to the lower hitches of the mower, through the use of the
pins and relative safety linch pins.
•Adjust the tractor sway blocks or chains to remove all side movement.
•Connect the tractor top link to the mower top link plate with the relative pin and linch pin. The 3-
point hitch system of the mower is designed to have a limited front to back flotation when
mowing on uneven terrain. Adjust the tractor’s top link until the top link plate of the mower is in
a vertical position respect to the deck (see picture below), in order to allow the mower to follow
the ground contour during mowing operation.
•Check for interference between mower's front wheel arms and tractor wheels. If there is
interference, adjust the position of the mower front wheel arms according to the instructions
described in section Wheel arms adjustment.
•Proceed with the driveline connection (see Section Driveline installation).
DRIVELINE INSTALLATION
Before installing the driveshaft, the operator must read the manuals of the tractor and driveshaft,
checking in particular that the rpm and direction of rotation of the tractor PTO match those of the
mower.
If the direction of rotation of the tractor PTO does not match that of the mower, contact the
Manufacturer or your Dealer.
To connect the driveshaft to the tractor and implement, the operator must:-
•Park tractor and mower on a flat surface, with parking brake set, engine off, and ignition key
removed.
•Check that driveshaft, mower and tractor safety shields are in good condition, otherwise they
should be replaced.
•Remove the PTO shield of the mower through the fixing screws.
•Insert the driveline yoke on the mower PTO by first lining up the splines, then ensure it is fully
located onto the shaft through its fastener/snap pin.
•Replace the PTO shield of the mower through the fixing screws.
•Insert the driveline yoke on the tractor PTO, then ensure it is fully located onto the shaft through
its fastener/snap pin.
•Hook to the tractor and mower the two retaining chains of the driveline shielding, to prevent
shielding rotation during functioning of the machine. The chains should not be too tight.
WARNING
The driveline must not exceed an angle of 15 degrees up or down while operating. Exceeding this
angle with driveline rotating can break the driveline and cause safety hazard to operator and by-
standers.
Always work with the driveline as straight as possible. This will prolong life of driveline and that of
its components, avoiding premature breakdowns.
9
CONNECTING TO THE TRACTOR - Continued

Before operating the mower, ensure that the size of driveshaft is adequate. The driveshaft sup-
plied with the machine has a standard length, therefore it may need an adjustment of the length,
depending on the tractor which the mower is connected to.
The length of the driveshaft must be such to:-
• Avoid bottoming out of the transmission tubes, when the driveshaft is in compressed position
(when the mower is raised up off the ground).
•Ensure an overlapping of the transmission tubes long enough to transmit the torque required,
when the driveshaft is in max extension (when the mower is in its lowest position in the ground).
When the driveshaft is at its minimum length (max compressed position), there must be at least 2
cm of distance between the ends of each transmission tube and the yokes side.
When the driveshaft is at its maximum operational extension, there must be an overlap between
the tubes profiles of 15 cm at least.
Adriveshaft that is too long may cause structural damages to the tractor and machine. If the
driveshaft is too long, it may be adjusted by removing it and shortening the tubes according to the
instructions provided by the Manufacturer in its use and maintenance manual.
Adriveshaft that is too short can cause disengagement of the tubes during operation, with a severe
hazard for the operator and structural damage to the tractor and machine. If the driveshaft is too
short, it must be replaced with a longer one. In this case contact the Manufacturer or your Dealer.
IMPORTANT
•Before operating the mower the first time, or before reusing the mower after a long term storage,
make sure that the driveshaft is lubricated in accordance with the instruction booklet.
•Always engage the tractor PTO at low rpm to minimise the effect of the peak torque on the
driveline and the machine.
10
DRIVELINE LENGTH CHECK

Before connecting the machine to the tractor it is required to check the stability of the tractor-
machine system. In order to determine the correct ballast to apply to the front of the tractor, to
ensure adequate distribution of the weight on the axles when the implement is in lifted position
(e.g. for transportation).
In order to assure the stability it is necessary that the following relationships are verified (see table
below for definitions):-
1) M x (S1+S2) ? 0.2 x T x i + Z x (d+i)
2) M < 0.3T
Consequently, the minimum ballast required is:-
Zmin = (M x (S1+S2) - 0.2 x T x i)/(d+i).
To determine the appropriate characteristics of the ballast, refer to the manual of the tractor.
CAUTION
The weight of the implement changes the stability of the tractor-mower set up, which could result in
loss of steering control and braking.

Before operating the mower, make sure you have read and understood the operating manuals of
the mower, tractor and PTO shaft, and followed what is described in the section "Set Up".
DANGER
During operation, adjustment, maintenance, repairing or transportation of the machine, the operator
must always use appropriate Personal Protective Equipment (PPE).
Before starting work, ensure that tractor, implement and driveline's safety guards are in good
conditions and fully functional.
START UP AND REUSING
Before the start up and before reusing the mower after a long term storage (e.g. after the end of
the season), perform the following pre-operational inspections and service of the implement,
to assure that the machine is in perfect condition and ready to be used:-
•Check that the mower has no damaged parts and has all mechanical parts in good condition.
Repair and / or replace the damaged parts.
•Check that the mower has no missing parts (pins, safety pins, plugs oil ...). Replace the missing
parts.
•Check that all guards and safety devices have no damage and are properly positioned. Repair
and / or replace the damaged shieldings, restore the correct position.
• Verify that the PTO driveshaft is properly installed (see section: Connection of the driveshaft).
•Check the presence of lubricant in all greasing points of the blade spindles, wheel arms and
driveshaft (see section Maintenance).
•Check for possible oil leaks from the gearbox. Identify the reason of loss, then repair and / or
replace the damaged components.
•Check the correct oil level in the gearbox (see section Maintenance).
•Check the belts for proper tension (see section Maintenance).
•Check that wheel spacers are all at the same height (see section Cutting height adjustment).
•Check that blades are not excessively worn and the blade bolts are correctly tightened (see
section Maintenance).
•Check that all the nuts and bolts are properly tightened. Refer to the tightening table in the
manual for proper torque values.
•Check that all safety decals are correctly positioned, in good condition and legible. Replace any
damaged decals.
•Check that there is no constraints that may prevent the movement of equipment, such as
wrappings or foreign objects around the blades, belts or driveline. Remove any constraint.
•Check the tractor, to ensure correct direction of PTO and rpm speed.
WARNING
Before the start up and whenever the coupling tractor is changed, check the clearance between
mower's front wheel arms and tractor wheels. Do not operate tractor and mower until this
clearance check has been performed. If there is interference, adjust position of the mower front
wheel arms according to instruction described in section Wheel arms adjustment.
Before the start up and before each use, make the following checks on the operating area to be
mowed:-
•Check that area is clear of foreign objects (rocks, branches or debris). Remove any obstacle
and visibly highlight obstacles that cannot be eliminated (e.g. by means flags).
•Make sure that there are no people or animals in the working area.
WARNING
Before conducting the above inspections and service, make sure that the tractor engine is off, all
rotating parts are completely stopped an the tractor is in park with the parking brake engaged
Make sure the mower is resting on the ground or securely blocked up.
12
OPERATING

Once all the checks above have been done, start tractor and mower as follows:-
• Start engine tractor and engage the tractor PTO at low rpm, making sure that the mower is in
the down position and resting on the ground, then increase speed engine until to 540 rpm.
• Start driving the tractor at low speed. Subsequently increase the ground speed until the desired
speed is obtained, depending on ground conditions (see section Operating instruction).
•Drive for a while operating the mower, then stop the tractor to check the quality of the work
performed and if the mower is adjusted properly. Once you have made necessary adjustments
(see section Adjustments), you may continue mowing following the instruction of section
"Operating instructions", to operate properly the mower and get the desired finish cutting. If you
need to get off the tractor, leave the mower in the down position and resting on the ground,
reduce engine speed and disengage PTO, set the parking brake, stop engine and remove the
ignition key.
OPERATING INSTRUCTIONS
The CMT/Finishing Series mowers have been designed to cut grass with heights up to 8”. It is
recommended to avoid cutting grass taller than 10”.
Always operate tractor PTO at 540 rpm to maintain proper blades speed and obtain a clean cut.
The proper tractor ground speed should be selected considering: height, type and density of grass,
grass condition (wet or dry), and ground condition (hilly, level, or rough). Generally a ground
speed from 2 to 5 mph (2-8 km/h) applies to most conditions. Atest run is suggested to define the
optimal working speed for proper own conditions.
Tall, dense grass should be cut at low speed, while thin medium-height grass can be cut at a faster
ground speed. Generally, the grass dispersion is increased by higher ground speeds.
Extremely tall grass should be cut in two passes. Set mower to a high cutting height on the first
pass, then position the mower at the desired height on the second pass. If possible, mow at a 90
degree angle in travel to the first pass.
Under certain conditions, tractor tyres may roll some grass down and prevent it from being cut at
the same height as the surrounding area. When this occurs, reduce the tractor ground speed but
maintain a 540 rpm engine speed, the lower ground speed will permit the grass to partially
rebound, thanks to the suction effect of the blades. If grass will not rebound enough to be cut
evenly, resulting in an uneven and not satisfactory appearance, cut the area twice.
In general, a lower cutting height gives a more even cut with less tendency to leave tyre tracks.
However, it is better to cut grass more often, rather than too short. Short grass deteriorates rapidly
in hot weather and invites weed growth during growing season.
Very low cutting heights should be avoided. Damaging shock loads occur when the blades strike
the ground repeatedly, this can cause damage to the mower.
IMPORTANT
For cleaner cuts and efficient mowing, the blades must be kept sharp. Sharp blades produce
cleaner cuts and require less power.
During operations:-
•Always keep the tractor engine at 540 rpm rate to ensure the correct blade rotation speed.
•Always keep a tractor speed adequate to ground conditions 2 to 5 mph (2-8 km/h). Reduce
speed in the case of hard or stony soils.
•When increasing or decreasing mowing ground speed, use gear selection (not engine speed).
This will maintain the constant maximum blade speed necessary for a clean cut.
•Choose a driving pattern that provides the maximum pass length and minimises turning; Plan
your pattern to travel straight forward whenever possible
•When working in the hills, if you can, cut in the direction of the slope, do not work along the
hillsides, making the steps from top to bottom to reduce the terrace. Where possible always try
13
START UP AND REUSING - Continued

to work up the slope. If this is not possible avoid hoeing along the contours of the hill and hoe
up and down the slope to avoid a terracing effect.
•Enter new areas carefully. Cut grass higher at first, allowing mower to clear hidden objects.
•Periodically check for foreign objects wrapped around the blades and/or rotor blades and re-
move them, after disengaging PTO, turn off the tractor engine, and remove ignition key.
•If the blades strike a foreign object, stop operating immediately, idle the engine speed and
disengage the PTO. Wait for all rotating parts, to stop, then raise the implement and proceed to
remove objects or debris, after stopping the tractor, set the parking brake, stop the engine and
remove the ignition key. Make sure rotor and blades are in good condition before restarting
operation. Repair any damages immediately.
If at any time the mower should jam, causing belt slippage for over two seconds, follow these
steps:-
•Bring the equipment into a previously cut area, allowing mower to clear accumulated material.
•Continue running for 2-3 minutes, allowing pulleys to cool. Stopping the mower in contact with a
very hot pulley will bake and ruin belt.
Typical problems that may occur operating the mower are described into Troubleshooting section,
together with their solutions.
DANGER
During operation, the machine can throw material at very high speed from the back, which could
result in personal or property damage. Pick up all rocks and other debris before mowing. Do not
allow people and animals to approach the operational area.
When working on uneven terrain, observe the following precautions:-
•Use extreme care and reduce ground speed on slopes and rough terrain.
•Use rear wheel weights, front tractor weights, and/or tyre ballast to improve stability in extremely
uneven terrain.
•Develop a safe working pattern suitable for the ground profile.
•Pass diagonally through sharp dips and avoid sharp drops to prevent hanging up the tractor and
implement.
•Operate the implement up and down steep slopes, DO NOT operate across steep slopes, to
prevent the tractor from tipping.
•Do not stop, start, or change directions suddenly on slopes.
• Watch for hidden hazards on the terrain during operation.
IMPORTANT
An anti-scalping roller is highly recommended for uneven terrains. The roller allows the front part
of the mower to ride over the mounds, helping to keep the mower from scratching the ground and
the blades from scalping the terrain.

OPERATING INSTRUCTIONS - Continued

WARNING
All adjustment operations must be performed with the tractor engine off, the PTO disengaged, the
mower lowered to the ground or on security stands, the parking brake set and the ignition key off.
Secure blocking prevents equipment from dropping due to hydraulic leak down, hydraulic system
failures, or mechanical component failures.
CUTTING HEIGHT ADJUSTMENT
The cutting height is the distance from the blades to the ground. It determines the height of the
mowed grass.
The cutting height can be adjusted by moving the position of the spacers (A) on the four wheel
yokes (see picture below).
•Placing spacers between the wheel arm and the wheel yoke raises the cutting height by the size
of the spacer.
•Removing spacers between the wheel arm and the wheel yoke lowers the cutting height by the
size of the spacer.
The CMT mowers have a cutting height adjustable from 1” to 5”. To adjust the working depth,
perform following steps:-
•Using the tractor, raise mower off the ground and support under it with secure blocking to keep
the mower from dropping down during adjustment operations.
•Holding wheel and yoke assembly up, remove the linch pin (B) from top of wheel spindle (C).
•Position the spacers (A) as desired. The spacers are assorted with heights of 1/4''-1/2'' and 1'',
to allow adjustment at multiple levels of cutting heights (from 1” to 5”).
•Replace the linch pin on top of the wheel spindle.
•Repeat the same for the other three wheels. Verify that the same amount of spacers are under
all 4 caster arms: only an equal adjustment will ensure a completely uniform cut.
•Remove safety block, then put mower down on the ground.
IMPORTANT:
Very low cutting heights should be avoided. Damaging shock loads occur when the blades strike
the ground. This can cause damage to the mower and drive.

ADJUSTMENTS

The front wheel arms of the CMT mowers can be set in two different configurations:-
•Inner position (see picture below - right side), that allows the outside edge of the mower to be
used for trimming under shrubs or fences;
•Outer position (see picture below - left side), that provides the most clearance to avoid
interference with tractor tyres.
To change configuration, do the following (see picture below):-
•Remove the screws (A), washer (B) and nuts (C) connecting the front wheel arm (D) to the rail
welded to the frame. To simplify the adjustment procedure, the belt cover (E) can be removed
from mower frame.
•Move the arm (D) from one side of the rail to the other.
•Position the arm according to proper own requirement, then secure them to the wheel rail
through the original hardware. Replace the belt cover if disassembled.
•Repeat the procedure for the other front wheel arm.
The rear wheel arms usually don't need to be moved, and should remain mounted in their original
position.

WHEEL ARM ADJUSTMENT

The lower hitch of the CMT mower can be set in two different configurations:-
•Fixed position (see picture below - right side).
•Floating position (see picture below - left side), that allows the mower to float and follow
contours over hilly and uneven terrain.
To change from fixed to floating position, remove screw (A), nut (B) and bushing (C) clamping the
two bent plates (D) to the front plate (E) welded to the frame.
To maximize the floating effect, providing at the same time the most clearance for interference with
tractor tires, the lower hitches can be moved forward (see picture).
17
LOWER HITCH ADJUSTMENT
Floating Position Fixed Position

The upper hitch of the CMT mower can be set in two different configurations:-
•Fixed position (see picture below - left side).
•Floating position (see picture below - right side), that allows the mower to float and follow
contour over hilly and uneven terrain.
To change from fixed to floating position, of three point hitch bracket, remove hex bolt (A), two
bushes (B) & nut (c) from bracket.
