high engine speed.
5. Tighten the screw securing the adjustment. Torque to
15–18 ft–lb (20–24 NSm)
6. Stop the engine.
7. Adjust the screw on the neutral return arm (Fig. 43)
until the gap between the end of the screw and the
switch contact is .090–.120 inch.

8. With parking brake disengaged, the switch circuit
should have continuity. If there is no continuity, move
switch down slightly until there is continuity.
9. Check adjustment as follows:
• Engage the parking brake. Depress the traction pedal
while engine is running and the PTO lever is
disengaged. The engine should stop within 2 seconds. If
engine stops, the switch is operating correctly; thus,
continue operation. If engine does not stop, there is a
malfunction in the interlock system.
10. Install steering tower cover and brake rod knob.
Changing the Hydraulic Oil
And Filter
Initially, replace the hydraulic system filter after the first
full day’s operation — NOT TO EXCEED 10 HOURS.
Replace the filter after every 200 hours and oil after every
1500 hours.
The axle housing acts as the reservoir for the system. The
transmission and axle housing are shipped from the factory
with approximately 6 quarts (5.6 l) of high quality
hydraulic fluid. Check the level of hydraulic fluid before
the engine is first started and daily thereafter. The
recommended replacement fluid is:
Toro Premium Transmission/Hydraulic Tractor
Fluid
(Available in 5 gallon pails or 55 gallon drums. See
parts catalog or Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
petroleum–based Universal Tractor Hydraulic Fluids
(UTHF) may be used provided its specifications fall within
