Using The Differential Lock; Four Wheel Drive - Toro 07211 Operator's Manual

back, the front wheels can even come off of the ground
when going over bumps or up a hill. This will result in a
loss of steering and may lead to the vehicle tipping over.
As a general rule, position the weight of the load evenly
from front to rear and evenly from side to side.
If a load is not secured, or you are transporting a liquid in a
large container such as a sprayer, it can shift. This shifting
happens most often while turning, going up or down hills,
suddenly changing speeds or while driving over rough
surfaces. Shifting loads can lead to tip overs. Always secure
loads so that they do not shift. Never dump the load while
the vehicle is sideways on the hill.
Heavy loads increase stopping distance and reduce your
ability to turn quickly without tipping over.
The rear cargo space is intended for load carrying purposes
only, not for passengers.
Caution
When raising or lowering bed or implement,
hydraulic oil will bypass over a relief valve when
cylinders reach the end of their travel, stopping
power assist to steering gear and increasing
steering effort. Release lift levers to NEUTRAL
after bed or implement is raised or lowered, to
regain assist to power steering.

Using The Differential Lock

The differential lock increases the vehicle's traction by
locking the rear wheels so one wheel will not spin out. This
can help when you have heavy loads to haul on wet turf or
slippery areas, going up hills and on sandy surfaces. It is
important to remember however, that this extra traction is
only for temporary limited use. Its use does not replace the
safe operation, already discussed concerning steep hills and
heavy loads.
The differential lock causes the rear wheels to spin at the
same speed. When using differential lock your ability to
make sharp turns is somewhat restricted and may scuff the
turf. Use the differential lock only when needed, at slower
speeds and only in first or second gear.
Warning
Tipping or rolling the vehicle on a hill will cause
serious injury.
• The extra traction available with the differential
lock can be enough to get you into dangerous
situations such as climbing slopes that are too
steep to turn around. Be extra careful when
operating with the differential lock on,
especially on steeper slopes.
• If the differential lock is on when making a
sharp turn at a higher speed and inside rear
wheel lifts off the ground, there may be a loss of
control which could cause vehicle to skid (Refer
to section on Differential Lock Operation). Use
the differential lock only at slower speeds.

Four Wheel Drive

Four Wheel Drive Only
The "Automatic on Demand" four wheel drive feature, on
this vehicle does not require operator activation. The front
wheel drive is not engaged (no power delivered to front
wheels) until the rear wheels begin to lose traction. The
bi–directional clutch senses the rear wheels slipping,
engages the front wheel drive and delivers power to the
front wheels. The four wheel drive system continues to
deliver power to the front wheels until the rear wheels have
enough traction to move the vehicle without slipping. Once
this occurs, the system stops delivering power to the front
wheels and the handling characteristics become similar to
that of a two wheel drive vehicle. The four wheel drive
system functions in both froward and reverse, however,
when turning the the rear wheels will slip slightly more
before power is delivered to the front wheels.
Warning
Tipping or rolling the vehicle on a hill will cause
serious injury.
• The extra traction available with the four wheel
drive feature can be enough to get you into
dangerous situations such as climbing slopes
that are too steep to turn around. Be careful
when operating, especially on steeper slopes.
