Using the Differential Lock

The differential lock increases the traction of the
sprayer by locking the rear wheels so that 1 wheel
does 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 intended
for temporary or limited use. Its use does not replace
the safe operation, already discussed concerning
N
steep hills and heavy loads.
The differential lock causes the rear wheels to turn at
the same speed. When using differential lock your
ability to make sharp turns is somewhat restricted and
the tires 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 sprayer 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 the inside
rear wheel lifts off the ground, there may
be a loss of control which could cause the
sprayer to skid. Use the differential lock
only at slower speeds.

Operating the Sprayer

To operate the Multi Pro Sprayer, first fill the spray
tank, then apply the solution to the work area, and
finally clean the tank. Complete all 3 of these steps
in sequence to avoid damaging the sprayer. For
example, do not mix and add chemicals in the spray
tank at night and then spray in the morning. This
would lead to separation of the chemicals and to
possible damage to the sprayer components.
