If it is impossible to increase the distance between mower and tractor, in order to maintain a
reasonable angle at the PTO, it is recommended to use a larger PTO, that is, a greater capacity
PTO (please refer to your dealer for more details).
Equal
PTO
Angles
Changing the mower angle can become harmful to the PTO. With the angle at each end being
unequal, there will be drastic increase of load on cross-kit and bearings. To avoid these problems,
it is recommended to keep tractor PTO shaft and mower input shaft always parallel.

WARNING- Telescopic tubes of a PTO should be set to minimum length to meet ideal conditions
for power transmission.
The minimum overlap between PTO tubes should be equal to 1/3 of the length of one half of the
tube by itself.
EQUAL ANGLES @ PTO JOINTS RECOMMENDED
AVOID UNEQUAL ANGLES @ PTO JOINTS
