OPERATING INSTRUCTIONS
To check operation of interlock switches:
1. Drive the machine slowly to a large, relatively open
area. Lower cutting unit, stop the engine and apply
parking brake.
2. Sit on seat. Depress the traction pedal. Try to start
the engine. The engine should not crank. If the engine
cranks, there is a malfunction in the interlock system
that should be corrected before beginning operation.
WARNING
Do not operate machine without implement
unless the PTO driveshaft is also removed.
3. Sit on seat and start the engine. Raise off the seat
and move the PTO lever to ON. The PTO should not
engage. If the PTO engages, there is a malfunction in
the interlock system that should be corrected before
beginning operation.
4. With the parking brake engaged, sit on seat and start
the engine. Depress the traction pedal. The engine
should kill when traction pedal is depressed. If the
engine continues to run, there is a malfunction in the
interlock system that should be corrected before
beginning operation.
PUSHING OR TOWING TRACTION UNIT
(Fig. 13)
In an emergency, the traction unit can be pushed or
towed. However, Toro does not recommend this as
standard procedure.
IMPORTANT: Do no push or tow the traction unit
faster than 10 mph. If traction unit must be moved a
considerable distance, transport it on a truck or
trailer.
1. Locate towing lever on right side of axle assembly.

1. Towing Lever
2. Remove cotter pin and clevis pin securing lever to
plate on side of axle.
3. Pivot lever rearward until hole is aligned with rear
hole in plate. Secure lever to rear hole with cotter pin
and clevis pin previously removed.
4. After completion of towing operation, pivot lever
back to original position and re-secure.
OPERATING CHARACTERISTICS
Practice driving the GROUNDSMASTER 3000D
because it has a hydrostatic transmission and its
characteristics are different than many turf
maintenance machines. Some points to consider
when operating the traction unit, cutting unit, or other
implement are the transmission, engine speed, load
on the cutting blades or other implement components,
and the importance of the brakes.
To maintain enough power for the traction unit and
implement while operating, regulate traction pedal to
keep engine rpm high and somewhat constant. A good
rule to follow is: decrease ground speed as the load on
the implement increases, and increase ground speed
as the load decreases.
Therefore, allow traction pedal to move backward as
engine rpm decrease, and depress pedal slowly as
rpm increase. By comparison, when driving from one
work area to anotherwith no load and cutting unit
raisedhave throttle in FAST position and depress
traction pedal slowly but fully to attain maximum
ground speed.
Another characteristic to consider is the operation of
the pedals that are connected to the brakes. The
brakes can be used to assist in turning the machine.
However, use them carefully, especially on soft or wet
grass because the turf may be torn accidentally.
Another benefit of the brakes is to maintain traction. For
example: in some slope conditions, the uphill wheel
slips and loses traction. If this situation occurs, depress
uphill turn pedal gradually and intermittently until the
uphill wheel stops slipping, thus, increasing traction on
the downhill wheel.
Use extra care when operating machine on slopes.
Make sure seat latch is properly secured. Drive slowly
and avoid sharp turns on slopes to prevent roll overs.
The cutting deck must be lowered when going
downhill for steering control.
