REAR DISC MOWER
OPERATOR’S MANUAL
After the mower has been attached to tractor, check the balance and steerability of tractor-mower
set. To do 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 (the mower must be in transport position
–
lifted upwards). If the
pressure on the front axis is at least 20 % of the whole set’s
pressure, it means the set is stable. If not,
the front axis should be balanced.
WARNING!
Before disconnecting the mower put the pin 1 into the hole 3 in the bar (
) to secure the linkage against falling. When the mower is connected the pin
should be in the bush 2 on the middle bar.

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.
WARNING!
If need be, shorten the PTO shaft according to its operator’s manual given by
the shaft’s manufacturer (
