are compatible and make sure that tractor's hitch load is adequate for the machine aggregated.
 Prior to mounting the machine, examine technical condition of the rake’s hitch assembly and
tractor's 3-point linkage.
 Use only genuine pins and cotters to mount the mower on a tractor.
 Once the machine is mounted on tractor check stability and manoeuvrability of the latter. Load
on the front axle should be approx. 20% of the weight of tractor. Otherwise, ballast front of the
tractor.
4.4. Transport
The lifting, handling and transporting operations can be very dangerous unless they are carried out
with the utmost caution. Have all persons not involved in the actual work move away from the area
and limit the zone where the operations are to be carried out. Also make sure that the area in which
the operations take place is clear and that there is a sufficient escape route, i.e. a free, safe zone to
which the operators can quickly move if the load should fall.
The safety hooks and ropes used to lift the machine must be of an adequate carrying capacity.
To minimize the risk of serious injury or death, do the following:
 When the machine is converted from the transport position to the work position and vice versa,
you could be pinched or crushed by some of its parts. Take extra care when carrying out these
maneuvers and have all persons keep well clear of the danger zone.
 Do not change position of the rake until there are no people or animals around (pay particular
attention to children).
 While transporting the rake, put a warning plate with combined lights and reflectors and
warning triangle on the rake.
 During transport, always put the rake in its proper and safe transport position. See section 5.2.
 Before moving the rake in transport position, make sure that the tractor’s PTO is turned off and
all rotating parts have come to a complete stop.
 Do not drive over 30 km/h (17 mph). Drive slower if road conditions are poor, especially on
irregular surfaces or steep slopes.
 Before transporting the rake make sure that mechanical locking pawls are properly locked on
pins.
 Before transporting the rake make sure that support legs are lifted and protected.

Operator’s manual

 The behavior of the tractor on the road, such as its turning and braking capacities, are affected
by the implements mounted.
 When driving on the road after work, check to make sure that the tires and soil working tools
are clean to prevent the road surface from becoming dirty.
 Make sure that the machine is not damaged during transport.
4.4.1.Putting the rake onto another vehicle for transport
The driver and the carrier are responsible for the rake’s transport safety. Equipment and parts must
be secured during transport.
To put the rake onto another vehicle in a safe way, please obey the following rules:
 Transport should be done by qualified and specifically trained personnel,
 Grab the rake by any lifting devices only in the places indicated by hook sign (Fig. 4),
 For rake lifting, use only lifting devices with hoisting capacity larger than rake’s weight shown
in data plate. This also applies to ropes and chains used for lifting,
 Do not lift if transport belts, belt suspensions, ropes are damaged. Whenever damage to these
parts occurs, replace with new ones,
 When mounting slings, chains, handles etc., always set the machine's center of gravity properly,
 To safely support the machine, use ropes of adequate length so that the angle between them is
no greater than 120°, and the angle between the strand and the vertical is no greater than 60°,
 Lift the machine with the utmost caution and move it slowly,
 No one should be within the range of action of the lifting equipment when any transporting
operations are being carried out.
 Collapsible parts should be blocked in transport position,
 When the rake is on the vehicle’s trailer, the machine should be secured against moving.
NOTE:
Securing maneuvering area and transport of the rake is the responsibility of a person who
does it.

manoeuvring with the aggregate might cause crushing of unauthorized
personnel.
-Be careful near link road zone of tractor's rear power lift. Contains sharp
parts.
-The machine should be mounted on a level ground.
Rotary rake Z2-780 / Z2-840 works properly with tractors (class 2.0 and power from 60 HP).
 The rake should be attached to a tractor by means of tractor's lower pull-cables as provided on
Fig. 6. For this purpose drive the tractor at the rake's catch, and then place hangers Wof
tractor's lower pull-cables on pins Son the rake's linkage.
 Once the rake is mounted turn support leg back and protect it with pin K.
 Connect hydraulic hoses:
-Z2-780 – one connector for lifting of work assemblies,
-Z2-780 H and Z2-840 – one connector for lifting of work assemblies and a pair of two-
side-operation connectors for control of raking width.
 Connect the machine's lighting cables to the tractor and check the lights for operation.
 Connect PTO shaft. If need be shorten the shaft as given in section 5.3.1.
Fig. 6. Connecting the rake to the tractor
 After the rake has been attached to tractor, check the balance and steerability of tractor - rake
set. In order to perform this, calculate to formulas given in the appendix or weigh the set, and
then drive on the scales only with front axis of the tractor. If the pressure on the front axis is at
least 20% of the whole set’s pressure, it means the set is stable. Otherwise, front axis should be
balanced.
5.2. Preparing the rake for transport
CAUTION:
Switching the machine from working to transport position, and the other way
round can only be done on an even and stable ground. Prior to starting any
works make sure that nearby the machine there are no unauthorized persons

5.4. Mounting PTO shaft
NOTE:
The manufacturer declines all liability for damage caused by an incorrectly fitted or used
PTO shaft.
The machine is delivered with a separate instruction manual for PTO shafts.
When connecting PTO shaft between tractor and rake, make sure that external guard tube of the
shaft is on the tractor’s side. The PTO shaft plastic guards have to be secured by fastening their
small chains to immovable parts of tractor and rake. The PTO shaft must operate at the lowest
possible angle. This will ensure that both shaft and the machine last as long as possible.
CAUTION:
The telescopic articulated shaft should remain mounted only during the rake's
operation period. For transport and service time the shaft should be
disconnected from the tractor's PTO shaft.
CAUTION:
Use machines with correspondingly designed telescopic articulated drive
shafts. For any service and repair works of the shaft and the machine, the
tractor engine and its drive must be disconnected.
CAUTION:
Handle all parts with utmost care. Never place your hands or fingers between
one part and the other. Wear safety clothes such as gloves, protective
footwear and goggles. The operation of shortening must be carried out with
the utmost care as the PTO shaft will have to be replaced if the telescopic
shafts are shortened to an excessive extent.
CAUTION:
The PTO shaft should be mounted only during operation time and
disconnected from tractor PTO for transport and service.
5.3.1. Shortening PTO shaft
CAUTION:
If need be, shorten the PTO haft according to its operator’s manual given by
the shaft’s manufacturer (Fig. 8).
