SECTION 3 -- FIELD OPERATION
3--22
With 21--spline shaft installed
• With the tractor stationary and the P.T.O. control
knob in the disengaged position, lift the
spring-loaded collar (2), beneath the knob, and
move the lever (1) fully to the right. This will
provide a P.T.O. speed of 1000 rev/min at 2120
engine rev/min.
NOTE: The P.T.O. range lever should always be in the
2120 position when the 21--spline shaft is installed. If
you only ever operate with a 21--spline shaft, leave the
range lever in this position.
27
With 6-- or 21--spline shaft installed
IMPORTANT: To avoid shock loads to the P.T.O.,
reduce engine speed to approximately 1000 rev/min
when engaging the P.T.O., then increase engine
speed by means of the throttle to obtain the required
P.T.O. speed.
With the engine running at 1000 rev/min. or less,
press the knob (1) and lift the collar (3) and knob up
to engage the P.T.O. The knob will remain up while
the P.T.O. is engaged and the adjacent warning light
(2) will be illuminated.
To disengage the P.T.O., press the P.T.O. control
knob (1), down.
NOTE: If the engine is stopped, the P.T.O. will not
operate when the engine is restarted until the P.T.O.
knob is reset. Return the control knob manually to the
‘off’ position (by pressing the knob down) then
re-engage the P.T.O., as previously described.
IMPORTANT: Although the P.T.O. may be engaged
or disengaged with the tractor moving or stationary,
do not attempt to change from one P.T.O. speed
range to another unless the tractor is stationary and
the P.T.O. disengaged -- control knob (1), fully down.
