Operating Characteristics - Toro Reelmaster 4000-D 03706 Operator's Manual

3. Rotate by–pass valve 90 degrees (Fig. 19). Opening the
valve opens an internal passage in the traction pump,
thereby by–passing hydraulic oil. Because oil is
by–passed, traction unit can be moved without
damaging the hydraulic system.

Important Make sure that hand brake is engaged
before opening the by–pass valve.
4. Before starting engine, close by–pass valve. Do not start
engine when valve is open.
Important
Running the machine with the by–pass
valve open will cause the hydraulic system to overheat.
Danger
Vehicle will roll with front wheel motors
disengaged. Vehicle must be on level surface or
wheels must be blocked. There is no effective
braking with wheel motors disengaged.
If towing, with front wheel motors disengaged,
Optional Tow Bar Assembly, Toro part no.
58–7020, must be used.

Operating Characteristics

Familiarization
Before mowing grass practice operating in an open area.
Start and stop the engine. Operate in forward and reverse.
Lower and raise cutting units simultaneously and
individually. Engage and disengage reels. Operate with all
cutting units down, then with only an individual cutting
unit. When you feel familiar with the machine, practice
operating around trees and obstacles. Also drive up and
down slopes using both mowing and transport speeds.

Danger
When operating the machine, always use the seat
belt and ROPS together. Do not use a seat belt
without a ROPS.
Warning System
If a warning light comes on during operation, stop the
machine immediately and correct the problem before
continuing operation. Serious damage could occur if the
machine is operated with a malfunction. For short intervals,
however, the emergency engine override button (Fig. 13)
can be used to operate the engine if it stops because of
overheating.
Mowing
When you are at the area to be mowed, release front, center
and outside cutting unit transport latches, lower cutting
units, engage hand brake and stop the engine.
Cutting Unit Grass Deflectors
Adjust grass deflectors to horizontal position (Fig. 20), so
clippings disperse backward; out and away from the cutting
units. This will prevent clumps of clippings, especially wet
clippings, dropping off the machine or cutting units, which
affects the visual appearance of the turf.
Note: Generally you can adjust the deflectors down slightly
in dry grass and up slightly in wet grass.

Match the ground speed limiter (Fig. 21) and reel speed
control knob (Fig. 22) to desired height–of–cut: refer to
Cutting Chart (Fig. 23). Use decal at side of steering
column as a guide only.
Start engine and move throttle to FAST so engine is
running at maximum speed. Disengage hand brake. To
move forward, press traction pedal forward (Fig. 21). Move
Mow–Backlap lever to MOW. Reels are now spinning.
Maintain traction pedal contact with ground speed limiter
(Fig. 21) to assure consistent clip and quality–of–cut.
