Transmission shaft
Operator’s safety
1. 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.
2. When attaching the shaft, make sure that the snap lock is FULLY ENGAGED - push and pull shaft until it locks.
3. Always keep protection guards and chains intact and make sure that it covers all rotating parts, including CV-joints at
each end of the shaft. Do not use without protection guard.
4. Do not touch or stand on the transmission shaft when it is rotating - safety distance: 5’ (1.5 meter). Also NEVER cross
over a rotating P.T.O. shaft to reach the other side of the sprayer.
5. Prevent protection guards from rotating by attaching the chains allowing sufficient slack for turns.
6. Make sure that protection guards around tractor P.T.O. and implement shaft are intact.
7. Always STOP ENGINE and remove the ignition key before carrying out maintenance or repairs to the transmission shaft
or implement.

DANGER! ROTATING TRANSMISSION SHAFTS WITHOUT PROTECTION GUARDS ARE FATAL.
P.T.O. installation
Always read the manufacturer’s instruction book before installation of
the transmission shaft!
First installation of the transmission shaft is done in the following way:
1. Before attaching transmission shaft, 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 transmission shaft must be shortened, pull the shaft apart. Fit the
two shaft parts at tractor and sprayer pump and measure how
much the shaft needs to be shortened. Also mark the protection
guards with the same length to be shortened.

DANGER! As P.T.O. shafts are dangerous, always read the manufacturer’s instruction book before making any changes
to the transmission shaft!
±
WARNING! The shaft must always have a minimum overlap that varies depending on the pump model.
Pump with 6 splines/540 r.p.m.
The shaft must always have an overlap (A) of minimum 1/3 of the length.
Example:
• Shortest distance (A) = 30”
• Each shaft should measure 20” (10” overlap).
