5. MOWER OPERATING.
You can use and operate the mower after reading carefully the service manual.
5.1. GENERAL CHARACTERISTICS AND DESCRIPTION
OF THE MOWER.
The Z 175-1 rotary mower cooperates with an over 23 kW tractor of II category. It is assigned
for mowing grass and low-stem green forage on even and sloped up to 12° fields and meadows.
In case of problems with the power take-off shaft please contact with a producer of this
particular PTO shaft.
The knife CMA 120 is not under warranty.
WARNING!
For proper work use appropriate type of PTO drive shaft:
Torque –460 Nm, Lmin. –560 mm, Lmax –885 mm.
Producer recommends PTO shafts of SIPMA, Poland –type 45R-502-2-BA-J501
www.lfmr.pl
The Z 175-1 rotary mower consists of the following main assemblies (Fig.2.):
-three-point frame (1)
-indirect drive (2)
-main drive (3)
-complete housing (4)
Fig. 2. Z 175-1 suspended rotary mower.
1- three-point frame, 2 –indirect drive, 3 –main drive, 4 –complete housing,
5 –drum, 6 –lock, 7 –PTO shaft housing, 8 –spring, 9 –tightening pin.

11
The mower is supplied partly disassembled. Assemble the machine in accordance with Fig. 12.,
13. and 16. of the parts list.
The three-point frame 1. is attended for mounting the mower on tractor.
The power is transmitted to the power take-off shaft through the jointed shaft, belt transmission
(indirect drive 2.) to the main drive 3. equipped with two drums 5. Three CMA120 cutting
knives are rotationally mounted in each drum and they deviate when they hit an obstacle, e.g. a
stone, which protects them from getting damaged. The knives have two cutting edges. When one
edge wears out, the cutting tools can be installed in the other drum, which rotates in the opposite
direction, thus they preserve dual life.
Each drum has replaceable transport strips preventing grass from getting wrapped in the drum
and decreasing the friction and wearing of drums. The drums and cutting knives whirl in
opposite direction forming the mowed green fodder into a swath roller.
The tightening pin 9. and indicator enables the tightening of the V-belt assembly.
The mower is equipped with a lock 6. which, in case of hitting an obstacle, reacts causing the
machine to move backwards. If that happens you must stop immediately and withdraw a little, so
that the lock is automatically locked up again.
In order to assure operational safety the mower is outfitted with housing 4. and aprons fastened
to them.
The end of power take-off shaft is protected with a special housing 7.
Spring 8. connecting the lift with the three-point frame decreases the pressure of drums to the
base preventing the turf from being devastated and decreasing wearing-out of the drum plates.
When working on uneven ground (max. decrease of pressure to the base) and with lighter
tractors on steep slopes a spring should be fixed in the down hole (best steerability of the tractor
is then achieved).
5.2. PREPARATION FOR TRANSPORT AND TRANSPORTING
CAUTION !
When charging to the working or transport position do not get between the tractor and the
cutting unit, setting the mower in working or transport position should be done closely to
the ground! When charging the mower to transport position, first, with utmost severity,
disconnect the jointed shaft from the tractor.
Before disconnecting the mower from the tractor, place the mower on a support 4. and rest
the jointed shaft on the yoke 5. (Fig. 3.)
5.2.1. LINKING THE MOWER AND THE TRACTOR INTO A WORKING
UNIT
Set up the three-point frame in a transport position –the transport rod 1. should be placed on
mandrel 2. of the three-point frame and secured with a pin 3. (Fig. 3.).
Connect the three-point frame 1. of the mower with the three-point suspension system of the
tractor in accordance with the manual of the tractor.
Lift the support 4., set it on the high position and block with a pin.

protected against turning according to the PTO shaft service manual.
5.2.3. TRANSPORTING THE MOWER MOUTED ON A TRACTOR.
CAUTION !
During the transport on public roads the mower should be equipped with cautionary
lighting panels according to obligatory home traffic regulations.
For driving to the workplace, disconnect the jointed shaft of the mower from the PTO shaft of
the tractor and rest it on the yoke 1. During transport the mower should be raised on a hydraulic
lift with the cutting tool turned backwards for safety.

5.3. SETTING THE MOWER IN WORK POSITION
CAUTION !
Before releasing the transport rod from the mandrel, position the mower and tractor
horizontally; if necessary, secure the mower against unintended departing.
Lower the mower to the ground, release the transport rod 1., mount the PTO shaft on the yoke
9. and lock the transport rod in the upper position.
Set up mower in the work position, fasten lock 4. on mandrel 2. and secure with pin 3.
Connect the PTO drive shaft with the tractor.
Set up the length of the upper pull rod in such a way that the drums in the work position are
parallel to the base or slightly slopped forward. In order to avoid fodder lost due to dual
cutting, never slope the machine backwards. Set up the bottom balance lever of the tractor in
such a way that the mower is positioned as shown in Fig. 6.
NOTICE:
Depending on the length of the upper pull rod of the tractor, the front as well as rear holes of the
three-point frame can be made use of.

CAUTIONS !
Start the mower only when set in working position.
Before working with the machine read the service manual carefully.
It is inadmissible to lift the mower on a hydraulic lift with power feed on and rotating
drums.
Never use the mower without shields and aprons. Operating the mower without shields
or with damaged shields is inadmissible due to danger of thrown out hard objects.
Before switching on the PTO shaft secure the jointed shaft shields against turning.
It is inadmissible to use the mower at a distance smaller than 50 m from strangers and
on stony ground or ground with constant obstacles. Handle with care especially near
roads and roadways.
In no instance should the speed of PTO shaft be increased above 540 rpm.
In case of excessive unloading of the front axle of the tractor, use front wheel weights in
order to load additionally .
When running on steep slopes the mower should be on the higher side of the slope.
Running the mower at high speeds of drums requires taking watchful attention to all
kind of unbalance causing vibration which can result in serious damage of the mower.
If increased vibration or a changed noise of operating mower is noticed, stop working
immediately. Continue the work with the machine only after you find and remove the
cause.
Conduct operations on the mower only after placing the mower on the ground, turning
off the PTO shaft, stopping the engine and immobilizing the tractor with a handbrake
or placing the wedges under the tractor’s wheels.
Do not start the engine or try to operate the mower indoors due to harmful exhaust
gases.
5.4. MOWING.
Slowly switch on the mower drive until achieving a full number of revolutions before the
mowing starts, that is 540 rpm
Match driving speed to the ground conditions and type of mowed material; avoid uneven and
stony ground.
When mowing on uneven ground or in cooperation with lighter tractors on steep slopes
suspend the spring (pos. 8. Fig.5.) to down hole.

15
5.5. PREPARATION FOR THE STOP AND DISCONNECTING THE
MOWER FROM THE TRACTOR.
To disconnect the mower from the tractor proceed as follows:
Set the mower in the transport position.
Set up the support 4 (Fig. 3.) in position for the stop.
Disconnect the PTO shaft from the tractor and put it on the yoke 5.
Disconnect the tractor’s three-point suspension system from the mower.
6. TECHNICAL MAINTENANCE
CAUTION !
Regularly control the condition of the knife-holder pins. When the pin wears out
halfway absolutely replace the knife-holders (Fig.7.).
When replacing the knives, notice should be taken to the correct mounting; they should
rotate freely on the pins.
Always fasten the knife-holders with original bolts M12x25-8.8 and nuts P M12-8-A,
tighten them with a torque 85 Nm.
Fig. 7. Minimal thickness of the knife-holder pin.
The condition of drums should be regularly checked. If the drum plates show cavities
caused by cutting tools or if they are overworn, proceed as follows:
-unscrew three bolts 7. which are screwed in at the bottom of sliding plate
(Fig. 15.)
-disassemble the sliding plate
-fasten the knife-holders 1. (Fig. 9.) in another place to let the cutting tool
adhere to an unworn surface.
Immediately replace damaged or worn drums.

16
6.1. ROUTINE TECHNICAL MAINTENANCE
Regularly check the condition of knives. Each drum should be equipped with three new or
uniformly worn CMA 120 knives. A suitable wrench is provided for replacing the knives
(Fig. 8.). Correctly settled knife should easily spin on the knife-holder pin. Fig. 8. shows how
to replace the cutting knives.
Systematically check the condition of transport strips. If they are worn to such a degree that
the drum can untimely wear out, replace strips with new ones.
During the season check the functioning of the lock every day (pos. 4. Fig. 5.). If the
mechanism functions while mowing, even though no obstacle has been struck, this means
that the force of the spring is too small and it should be tighten better with a securing nut
(pos. 5. Fig. 5.).
During the first few hours of work carefully watch the behaviour of V-belts, after 0,5 –
4 hours of work under full load –tighten belts. The ‘x’ clearance (Fig. 5) should be
approximately 1 mm. This clearance is adjusted with nuts 6. and 7. Proceeding like this
the initial stretch is considered. After next 24 hours of work check the indicator again
and tighten belts if necessary. Maximum ‘x‘ clearance cannot exceed 3 mm.
Next inspections can be done even after few hundred hours of work.
Notice: If the V-belts are stressed more than the indicator is showing, a damage to ball
bearings can be caused in result of overloading.
After a few working hours of a new or repaired machine check if all the bolts and nuts are
properly tightened, especially the bolts tightening the lift. Repeat the checking in regular
intervals.
If the gasket between the shield and main frame (for example after repairing the machine)
needs to be replaced, use only original gaskets. Stick them on exactly in place of the old one.
Bolts that connect shield with main frame should be tighten with torque 48 Nm.

17
6.2. LUBRICATION.
During the operational use the mower should be lubricated every day (the lubricating points
are shown in Fig.10.)
The main frame filled with grease “Liten EPX 00” ORLEN OIL doesn’t require checking.
If a repair has been conducted, the amount of lubricant should be refilled! The lubricant
should level up to the bottom part of the horizontal shaft (5,5 kg).
Fig. 10. Lubricating points.
6.3. MAINTENANCE AND STORAGE
-Every time after finished work clean the machine of plant remains and dirt and check
the connection of parts and assemblies.
-When the season is over, clean the mower and carry out a technical survey. If any
defects are found, remove them. If paint has come off in some places, they should be
cleaned of rust and repainted. Cover unpainted parts with a thin layer of grease e.g.
STP, vaseline. It is recommended to store the mower indoors to secure it from moisture
and precipitation.
