switch
6. Press down on parking brake rod and push up on switch
until compressed length of switch plunger is .030"
(Fig. 52, inset) . This the distance between the brake rod
paddle and switch plunger housing.
7. Tighten switch mounting screws and nuts.
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 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
1000 hours.
The axle housing acts as the reservoir for the system. The
transmission and axle housing are shipped from the factory
with approximately 5 quarts (4.7 l) of high quality
hydraulic fluid. Check the level of hydraulic fluid before
the engine is first started and daily thereafter.
Appropriate hydraulic fluids are listed below.
The following list is not assumed to be all–inclusive.
Hydraulic fluids produced by other manufacturers may be
used if they can cross reference to find an equivalent to the
products listed. Toro will not assume responsibility for
damage caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.
Universal Tractor Hydraulic Fluid
Mobil
Amoco
Chevron
Conoco
Exxon
Pennzoil
Shell
Texaco
Note: Fluid to operate the power steering is supplied by the
hydraulic system transmission charge pump.
Cold weather start–up may result in "stiff" operation of the
steering until the hydraulic system has warmed up. Using
proper weight hydraulic oil in system will minimize this
condition.
Note: Many hydraulic fluids are almost colorless, making it
difficult to spot leaks. A red dye additive for the hydraulic
system oil is available in 2/3 oz. (20 ml) bottles. One bottle
is sufficient for 4–6 gal (15–22 1) of hydraulic oil. Order
part no.44–2500 from your authorized Toro distributor.
