4.1. LOWER HITCHES POSITIONING
The RC-SERIES Cultivators are designed to be mounted on tractors equipped with:
3-point Hitch Category I (ISO 730 standard);
Quick Hitch Category I (ASABE Standard).
The position of the lower hitches must be adjusted accordingly.
If the tractor is equipped with a Quick Hitch Category I (ASABE Standard), verify that the lower
clevises show the pins oriented up (see figure), so that the distance between upper and the lower
pins is 15'' (381 mm), as required from the standard.
If this not occurs, proceed as follows for each of the two clevises::
remove the U-bolt and the clevis from the square tube;
invert the clevis orientation and reposition it on the square tube at distance of 13 7/16'' from
the center of Cultivator PTO. At the end of the operation the lower clevises should be positioned
symmetrically respect to Cultivator PTO, at distance of 26 7/8'' (683 mm);
re-tighten the U-bolt, referring to the tightening table of this manual.
If the tractor is equipped with a 3-point Hitch Category I (ISO 730 standard), verify that the lower
clevises show the pins oriented down (opposite than figure above), so that the distance between
upper and the lower pins is 18'' (460 mm approx), as required from the standard.
If this not occurs, proceed as follows for each of the two clevises:
remove the U-bolt and the clevis from the square tube;

RC-Series Rotary Cultivators

invert the clevis orientation and reposition it on the square tube at distance of 13 7/16'' from
the center of Cultivator PTO. At the end of the operation the lower clevises should be positioned
symmetrically respect to Cultivator PTO, at distance of 26 7/8'' (683 mm);
re-tighten the U-bolt, referring to the tightening table of this manual;
remove from upper and lower pins the bushings provided for coupling with Quick Hitch, through
the extraction of elastic pins. Replace the elastic pins when finished. Store the bushings for
possible future use.
4.2. CONNECTING TO THE TRACTOR
To connect the Cultivator to the tractor the operator must do the following:
drive the tractor in reverse, up to align the rear lifting arms to lower hitches of the Cultivator in
parking;
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 Cultivator, through the use of
the pins and the relative safety split pins;
raise the Cultivator until PTOs of tractor and machine are at the same height, then adjust the 3-
point top link so that the front of the machine is leveled to the back (the axis of the Cultivator
PTO must be parallel to the ground), in order to limit stress transmitted to the Cultivator
through the cardan shaft;
make sure that left side of the Cultivator is leveled with the right, by adjusting the tractor lifting
arms, then lock the arms to prevent swinging that could compromise the stability of tractor and
machine;
finally adjust the parking stand, placing it at the highest point by means of the related elastic
pin.
4.3. DRIVELINE INSTALLATION
Before installing the driveshaft, the operator must read the manuals of driveshaft and tractor,
checking in particular that rpm and direction of rotation of the tractor PTO match those of the
Cultivator.
If the direction of rotation of the PTO tractor does not match that of the Cultivator, contact the
manufacturer or your dealer.
To connect the driveshaft to the tractor and implement, the operator must:
park tractor and Cultivator on a flat surface, with parking brake set, engine off, and ignition key
removed;
check that safety devices of driveshaft, Cultivator and tractor are in good condition, otherwise
provide for their replacement;
remove the PTO shield of the Cultivator through the fixing screws;
position the driveshaft with clutch turned towards the implement side;
insert the clutch hub on the Cultivator PTO, then ensure its tightening onto shaft through
its fastener;
replace the PTO shield of the Cultivator through the fixing screws;
insert the driveshaft yoke on the tractor PTO, then ensure its tightening onto shaft through its
fastener;

RC-Series Rotary Cultivators
14
hook to the tractor and Cultivator the two retaining chains of the the driveline shielding, to
prevent shielding rotation during functioning of the machine.
DRIVELINE LENGTH CHECK
Before operating the Cultivator, ensure that the size of driveshaft is adequate. The driveshaft
supplied with the machine has a standard length, therefore it may need an adaptation of the
length, depending of the tractor which the Cultivator is combined.
The length of the driveshaft must be such to:
avoid bottom out of the transmission tubes, when the driveshaft is in compressed position
(when Cultivator is raised up off the ground);
ensure an overlapping of the transmission tubes enough to transmit the torque required, when
the driveshaft is in max extension (when Cultivator is in its lowest position in the ground).
When the driveshaft is at its minimum length (max compressed position), there must be at least a
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.
A driveshaft that is too long may cause structural damages to the tractor and machine. If the
driveshaft is too long, it may be adapted by removing it and shortening the tubes according to the
instructions provided by the manufacturer in its use and maintenance manual.
A driveshaft too short can cause disengage of the tubes during operation, with 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.

RC-Series Rotary Cultivators
15
IMPORTANT
before operating the Cultivator the first time, make sure that the driveshaft is lubricated in
accordance with how indicated in the instruction booklet;
before operating the Cultivator the first time, and after long periods of inactivity, make sure that
the driveline clutch has run a short "run in" in accordance with what indicated in the instruction
manual of the manufacturer, removing the possible oxidation of the components that may
compromise the correct slipping during the usage (see also section "Maintenance");
always engage the tractor PTO at low rpm to minimize the effect of the peak torque on the
driveline and the machine.
4.4. TRACTOR-CULTIVATOR STABILITY
The weight of the machine modifies the stability of the system tractor-Cultivator, resulting in loss
of steering control and braking.
The front axle of the tractor should always loaded with at least 20% of the overall weight of the
system tractor-Cultivator.
CAUTION
Check the lifting capacity and stability of the tractor and, if necessary, applying the front ballast.
To determine the appropriate characteristics of the ballast, refer to the manual of the tractor.
5. OPERATING
Before operate the Cultivator, make sure you have read and understood the operating manuals of
the Cultivator, 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 all machine guards are in good conditions and fully functional.
During operation, the machine can throw material from the back: prevent people and animals to
approach the operational area.
5.1. START UP
Before the start up and before each use, perform the following pre-operation inspections and
service of the implement:
check that the Cultivator has not damaged functional parts and has all mechanical parts in good
condition. Repair and / or replace the damaged parts;
check that the Cultivator has no missing parts (pins, safety pins, plugs oil ...). Restore the
missing parts;
check that all guards and safety devices have no damages 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 drive shaft);

RC-Series Rotary Cultivators
16
check that the driveshaft clutch is in good condition, and that its components are not subject to
"sticking" (see section: Maintenance / Driveline);
check the presence of lubricant in all greasing points of the Cultivator (driveshaft, supports...)
(see sect. Maintenance / Driveline and Maintenance / Support rotor);
check for oil leaks from the gearbox or the transmission side cover. Identify the reason of loss,
then repair and / or replace the damaged components;
check the correct oil level in the gearbox and in transmission side box (see section
maintenance);
check that blades are not excessively worn and the relating hardware is correctly tightened (see
sect. Maintenance);
check that all the Cultivator hardware is 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. Remove any
constraint.
Before the start up and before each use, make the following checks on the operating area
identified for tillage:
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 in the working area exposed there are no people or animals;
make sure the soil to be worked is not too grassy, muddy, sandy or rocky.
WARNING
Before conducting the above inspections and service, make sure the tractor engine is off, all
rotation parts are completely stopped and the tractor is in park with the parking brake engaged.
Make sure the Cultivator is resting on the ground or securely blocked up and the tractor lifting
hydraulics locked.
Once all the checks above have been done, start tractor and the Cultivator as follows:
start the tractor and engage the tractor PTO at low rpm, making sure that the Cultivator is NOT
in the raised position but close to the ground, then increase speed engine until to 540 rpm;
lower the Cultivator on the ground and simultaneously start driving the tractor at low speed.
Subsequently increase the ground speed depending on ground conditions;
If the environmental temperature is very cold , it's recommended to wait a few minutes with the
PTO of the tractor at low rate before lowering the Cultivator completely on the ground;
drive for a while operating the Cultivator, then stop the tractor to check the quality of the work
performed. If you need to get off the tractor, lift the Cultivator just out of the ground, reduce
engine speed and disengage PTO, set the parking brake, stop engine and remove the ignition
key;
If the working depth and/or soil texture are not as desired, correct them by adjusting the skids
and/or the rear cover (see section Adjustments).
