Operating manual
Rear disc mower with central suspension
- hydro-pneumatic or spring suspension
- 2 5 -
Lift support leg (S) and secure it with cotter pin.
As the mower is mounted adjust the machine's position with upper link (G) and lower links
(W). Set the tractor's lower links stable so that the mower does not swing in either side and
the catch is in central position.
Connect hydraulic hoses.
Connect the machine's lighting cables to the tractor and check the lights.
Connect PTO shaft. If need be shorten the shaft as per item 3.3.
After having connected the mower to the tractor check the lengthwise balance and steering
ability of the tractor-mower aggregate. Therefore weigh the aggregate first, then drive onto
the scale only with the front axle of the tractor (the mower must be in the transport position,
and lifted). If the weight of the front axle of the tractor is at least 20% of the entire weight of
the unit then steering ability has been preserved. If this is not the case the front axle should
be additionally weighed down.
Fig. 12. Connecting the mower to the tractor
5.1.1. Mounting PTO shaft
PTO shaft’s end with overrunning clutch should be mounted on mower’s side.
When connecting PTO shaft between tractor and mower 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 mower. 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:
If need be, shorten the PTO haft according to its operator’s manual given by the
shaft’s manufacturer (Fig. 13).
