2.
Lower the roll bar to the down position.
3.
Install the two pins and secure them with the hairpin
cotter pins.
Important:
Ensure that the seat is secured with
the seat latch.
4.
To raise the roll bar, remove the hairpin cotter pins
and remove the two pins.
5.
Raise the roll bar to the upright position and install the
two pins and secure them with the hairpin cotter pins
Important:
Always use the seat belt when the roll bar
is in the raised and locked position. Do not use the seat
belt when the roll bar is in the lowered position.
Pushing or Towing the
Machine
In an emergency, the machine can be moved forward by
actuating the bypass valve in the variable displacement
hydraulic pump and pushing or towing the machine.
Important:
Do not push or tow the machine faster than
3-4.8 km/h (2-3 MPH) because internal transmission
damage may occur. The bypass valves must be open
whenever the machine is pushed or towed.
1.
Raise the seat. The bypass valves are located below the
front of the fuel tank (Figure 33).
2.
Rotate each valve 3 turns counter-clockwise to open
and allow oil to bypass internally.
Do not open
more than 3 turns.
Because fluid is bypassed, the
machine can be slowly moved without damaging the
transmission.
3.
Close the bypass valves before starting the engine.
Torque to 70 N-m (52 ft-lb) to close the valve.

Bypass valve (2)
Important:
If the machine must to be pushed or
towed in reverse, the check valve in the four-wheel
drive manifold must also be bypassed. To bypass
the check valve, connect a hose assembly (Hose
Part No. 95-8843, Coupler Fitting No. 95-0985
[Qty. 2], and Hydraulic Fitting No. 340-77 [Qty.
2]) to the reverse traction pressure test port,
located on the hydrostat, and on the port located
in-between ports M8 and P2 on the rear traction
manifold which is located behind the front tire.
Jacking Points
There are jacking points located at the front and rear of the
machine.
•
On the frame at the inside of each front drive tire
•
At the center of the rear axle
Tie Downs
There are tie downs located at the front, rear and sides of
the machine.
•
Two on the front of the operator's platform
•
The rear bumper
Operating Characteristics
Practice driving the machine 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 implements
are the transmission, engine speed, load on the cutting blades
or other implement components, and the importance of the
brakes.
With Toro Smart Power™, the operator does not have
to listen to the engine speed in heavy conditions. Smart
