(forward)
4. Adjust the stop bolt all the way in (away from
the traction pedal).
5. Using your hand, push the traction pedal all the
way forward, with light pressure, until it stops
and hold it there. Maintain only light pressure
on the pedal when pushing it to the full forward
position.
6. With the seat in the raised position, verify that
you are not over loading the linkage by making
sure the transmission does not move when the
pedal is depressed to the stop.
7. Adjust the stop bolt out (towards the traction
pedal) until there is a gap of 1.5 mm (0.060
inch) between the head of the stop bolt and the
bottom of the traction pedal.
8. Tighten the jam nut to secure the stop bolt in
place.
9. The reverse stop bolt may be adjusted if the
maximum reverse speed is not acceptable. For
a faster reverse speed, adjust the stop bolt in.
For a slower reverse speed, adjust the stop bolt
out.

Hydraulic System
Maintenance
The reservoir is filled at the factory with approximately
17 liters (18 quarts) of high quality tractor
transmission/hydraulic fluid. The recommended
replacement fluid is as follows:
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,
Mobil® 424 hydraulic fluid may be used.
Note:
Toro will not assume responsibility for damage
caused by improper substitutions.
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 20 ml (2/3 oz.)
bottles. One bottle is sufficient for 15-22 1iters (4-6
gallons) of hydraulic oil. Order part number 44-2500
from your authorized Toro distributor.
Checking the Hydraulic
System
Service Interval: Before each use or daily
Check the level of the hydraulic fluid before the engine
is first started and daily thereafter.
1. Position the machine on a level surface. Release
the traction pedal to the neutral position and
start the engine. Run engine at lowest possible
RPM to purge the system of air. Do not engage
the PTO. Raise the deck to extend lift cylinders,
stop the engine, and remove the key.
2. Remove the hydraulic fill cap
filler neck.
3. Remove the dipstick and wipe it with a clean rag
(Figure 66).
4. Screw the dipstick all the way into the filler neck;
then remove it and check level of fluid
66).
If level is not within notched area of the dipstick,
add enough high quality hydraulic fluid to raise
level to within the notched area. Do not overfill.
5. Replace the dipstick and thread the fill cap
finger-tight onto filler neck.
6. Check all hoses and fittings for leaks.
