Attaching the PTO shaft:
Before installing the PTO shaft make sure that the RPM rating and the direction of rotation match those of the
tractor. Carefully read the PTO shaft and tractor instructions. Before operation, make sure that the guards are
installed on the power take off of the tractor and PTO shaft. Make sure that they cover the PTO shaft through-
out its length. Note: The PTO shaft may be too long and require shortening. See
“ Shortening a PTO
driveline ” below.
Press the locking pin on the PTO yoke and slide yoke on to the PTO of the tractor until the pin seats. Pull on
PTO shaft to make certain it is locked in place. Repeat the procedure for the machine end. Attach the PTO
cover
’ s safety chains to a stationary part of the tractor. Leave some slack in the chain to accommodate move-
ment.
Shortening a PTO driveline:
1. With the machine attached to the tractor ’ s
3 - point hitch, and the PTO shaft not in-
stalled, separate the PTO shaft. Attach the
machine end to the machine and the other
end to the tractor PTO input shaft.
2. Raise the machine by using the tractor ’ s
hydraulic 3 - point hitch to its maximum
lift height.
3. Hold the half shafts next to each other and
mark them so each end is approximately
1/2” from hitting the end of the telescopic
profiles.
4. Shorten the inner and outer guard tubes
equally.
5. Shorten the inner and outer profiles by the
same length as the guard tubes. Using a
rattail file, round off all sharp edges and burrs. Grease the telescopic profile generously before reassem-
bling.
When fully extended, the tubes must overlap by at least 1/3 of the length of the pipes
(LT). When retracted, the min. acceptable clearance is 1
- 2 cm (3/8” - 3/4”)
