1. Traction pedal
2. Stop bolt w/ jam nut
(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 L (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
neck.
3. Remove the dipstick and wipe it with a clean rag
(Figure 49).
4. Screw the dipstick all the way into the filler neck; then
remove it and check level of fluid
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.
