COMMANDER OPERATOR’S MANUAL
P.T.O. Shaft Operator Safety
WARNING:
ALWAYS STOP ENGINE BEFORE
ATTACHING THE TRANSMISSION SHAFT
TO TRACTOR P.T.O. MOST TRACTOR P.T.O.
SHAFTS CAN BE ROTATED BY HAND TO FACILITATE
SPLINE ALIGNMENT WHEN ENGINE IS STOPPED.
When attaching the shaft, make sure that the snap lock
is FULLY ENGAGED - push and pull shaft until it locks.
WARNING: ROTATING TRANSMISSION
SHAFTS WITHOUT PROTECTION GUARDS
ARE FATAL.
Always keep protection guards and chains intact and
make sure that the guards cover all rotating parts,
including CV-joints at each end of the shaft.
Do not use without protection guard.
Do not touch or stand on the transmission shaft when it
is rotating - safety distance: min 5’ (1.5 meters).
Prevent protection guards from rotating by attaching
the chains, allowing sufficient slack for turns.
Make sure that protection guards around the tractor
P.T.O. and implement shaft are intact. Always STOP
ENGINE and remove the ignition key before carrying
out maintenance or repairs to the transmission shaft or
implement.
INSTALLATION OF P.T.O. SHAFT
WARNING: THE P.T.O. SHAFT ANGLE WILL
CHANGE WHEN RAISING AND LOWERING
THE CLEVIS. TO PREVENT EXCESSIVE
LOADING AND BINDING ON THE P.T.O. SHAFT, IT
MAY BE ADVISABLE TO LEAVE THE P.T.O. SHAFT
DISCONNECTED UNTIL THE CLEVIS ADJUSTMENT
IS COMPLETED. THEN THE P.T.O. SHAFT ADJUST-
MENTS CAN BE MADE.
Initial installation of the shaft is done as follows:
1. Attach sprayer to tractor and set sprayer in the
position with shortest distance between the tractor
and sprayer pump P.T.O. shafts.
2. Stop engine and remove ignition key.
3. If P.T.O. shaft must be shortened, the shaft is pulled
apart. Fit the two shaft parts at tractor and sprayer
pump and measure how much it is necessary to
shorten the shaft. Mark the protection guards.
Sprayer setup
Note:
The minimum allowable overlap for the shaft
depends on the pump model.
Pump with 6 splines (540 r.p.m.)
The shaft must always have a minimum overlap of 1/3
the length.
Pump with 21 splines (1000 r.p.m.)
The shaft must always have a minimum overlap of 2/3
the length.
4. The two parts are shortened equally. Use a saw, and
file the profiles afterwards to remove burrs.
5. Grease the profiles, and assemble male and female
parts again.
6. Fit the shaft to tractor and sprayer pump.
Note:
Female part towards tractor. Fit chains to prevent
the protection guards from rotating with the shaft.
7. To ensure long life of the P.T.O. shaft, try to avoid
working angles greater than 15
°
