Using The Weight-Transfer/Traction Assistance; Clearing Debris From The Cutting Units; Operating Tips - Toro T4240 Operator's Manual

Using the
Weight-Transfer/Traction
Assistance
A variable hydraulic weight transfer system is provided
for improving tire grip with the grass surface - traction
assistance.
Hydraulic pressure in the cutting units lift system
provides a lifting force which reduces the cutting units'
weight on the ground and transfers the weight as a
downward force onto the tires of the machine. This
action is known as weight transfer.
To engage weight transfer: You can vary the amount
of weight transfer to suit operating conditions by
rotating the weight transfer hand wheel as follows:
1. Release the valve locknut 1/2 turn anti-clockwise
and hold.
2. Rotate the valve hand wheel.
•
Anti-clockwise to reduce weight transfer.
•
Clockwise to increase weight transfer.
3. Tighten the nut.

Clearing Debris from the
Cutting Units
WARNING
Never attempt to rotate the cutting cylinders
by hand.
• There may be some residual pressure in
the hydraulic system which could cause
injury through sudden movement of the
cylinder(s) when the blockage is released.
• Always wear protective gloves and use a
suitable strong wooden instrument.
• Ensure that the wooden instrument will
fit between the blades and through the
cylinder and is long enough to provide
sufficient leverage to release the blockage.
1. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key.
2. Disengage all drives.
3. Check that all power sources are stopped.
4. Release all stored energy devices.
5. Check that all moving parts are stationary.
6. Using a suitable strong wooden instrument,
remove the blockage. Make sure that the
wooden instrument is properly supported in the
cylinder and avoid the use of excessive force to
prevent damage.
7. Ensure that the wooden instrument is removed
from the cutting cylinder before starting the
power source.
8. Repair or adjust the cutting unit if required.

Operating Tips

Becoming Familiar with the
Machine
Before mowing grass, practice operating the machine
in an open area. Start and stop the engine. Operate in
forward and reverse. Lower and raise the cutting units
and engage and disengage the cutting units. When
you feel familiar with the machine, practice operating
up and down slopes at different speeds.
Understanding the Warning
System
If a warning light comes on during operation, stop the
machine immediately and correct the problem before
