Operating manual
Rear disc mowers with central suspension
- with hydro-pneumatic or spring suspension
- 3 5 -
WARNING:
Due to the high revolutions of the discs, blade holders should be replaced in
pairs of the same weight - every holder has its weight stamped on it. Otherwise,
the resulting lack of balance will cause the disc to vibrate and may cause
damage to the cutting bar guard.
ATTENTION:
Installing the blade the wrong way will cause big furrows of grass. When
installing blades, pay special attention to the rotation direction of the blade on
the holder.
6.4. Setting mowing height
The desired mowing height is obtained through changing the length of
the upper regulated tie S (Pict 9) of the suspension. Extending the tie
increases and shortening it decreases mowing height. Mowing height is
shown by the indicator located on the suspension frame (Pict 19);
recommended height is 6-7 cm.

6.5. Use and adjustment of the load reducing chain.
Pict. 20a. The load reducing chai Pict 20b. Height of the mower in the operating position
The load reducing chain is used to set a permanent height of the mower during operation. It facilitates
the correct positioning of the mower for operation and reduces the load on the hydraulic actuator of
the tractor.
When connecting the mower to the tractor we insert fitting A (Pict 20a) of the chain onto the pin B of
the upper tie. The length of the chain should be adjusted so that in operating position the mower is at
a height shown on (Pict 20b) and the tilt of the mower (see picture on page 1).
