Dual Stage Clutch
A Tractor equipped with" Live" PTO has
a dual clutch as standard equipment and a
single pedal operates both clutch stages.
Movement of the pedal through the first
stage disengages the primary clutch, which
will stop the Tractor's forward or reverse
motion. Movement through the second stage
disengages the secondary clutch, which con-
trols the hydraulic pump and PTO shaft.
Single Stage Clutch
A Tractor equipped with ''Independent''
PTO uses a single disc clutch. Fully de-
pressing the clutch pedal stops only the for-
wardor reverse motion of the Tractor, pro-
viding a constant running hydraulic system.
On MF 135 Special Tractors, a single
disc clutch only, is used. Full depression of
the clutch pedal stops the Tractor movement,
also stopping the hydraulic pump and PTO
shaft.

Fig. 5 - Differential Lock Pedal
Differential Lock Pedal (Option)
(See Fig. 5)
To engage the differential lock, depress
the differential lock pedal. To disengage
the differential lock turn the front wheels to
the right or apply the right brake. Differ-
ential lock is especially advantageous where
traction is poor. By depressing the differ-
ential lock pedal, the rear axles are locked
together so both rear wheels pull simul-
taneously, providing increased traction.
IMPORT ANT: For best results, en-
gage differential lock before exces-
sive slippage occurs. DO NOT EN-
GAGE DIFFERENTIAL LOCK WITH
WHEEL SPINNING EXCESSIVELY .
If this condition occurs, depress
clutch pedal and then, engage dif-
ferential lock.
