Sand Application Rate; Sand Precautions; Preparing For Cold Weather Operation - Toro Workman Topdresser 1800 Operator's Manual

Sand Application Rate

The rate of sand applied depends on the gate setting
and the gear/range setting. Sand varies in moisture
and coarseness (size of grain) which affects the
rate. These factors must be taken into consideration
when deciding the amount of sand required for the
application. Test a small area to decide the correct
amount. To increase the application rate, either open
the gate to a higher scale mark or shift the Workman
vehicle to a lower gear.
Note:
On vehicles with serial numbers 240000001
and up, the sand application rate decreases when
you turn the vehicle. Avoid making sharp turns when
topdressing.
To ensure consistent application, from green to green,
use the tachometer and/or hand throttle to maintain
constant engine speed while topdressing.
WARNING
Tipping or rolling the vehicle on a hill will
cause serious injury.
If the engine stalls or you lose headway on a
hill, never attempt to turn the vehicle around.
Always back straight down a hill in reverse
gear.
Do not back down in neutral or with the clutch
pressed, using only the brakes.
Never add sideboards or panels to the top of
the hopper to increase the load capacity. The
additional weight will cause tipping or rolling
of the vehicle and lead to serious injury.
Do not drive across a hill: drive up and
down the hill. Avoid turning on a hill. Do
not accelerate or decelerate fast. A sudden
change in speed can initiate a tipover.

Sand Precautions

The machine is equipped with a flexible gate edge
(Figure 21) and a spring release mechanism to reduce
the chance of sand chunks or rocks getting lodged
during operation. To ensure long belt life, sift or check
the sand for rocks with sharp edges that may damage
conveyor belt.

Preparing for Cold Weather
Operation
You may use the machine in cold weather. With
certain limitations, you may use the machine to apply
a salt/sand mixture on pavement for ice control. The
PVC conveyor belt material becomes very stiff in cold
weather and requires more power to operate belt. The
life of the belt is reduced by approximately 50% when
operated below temperatures of 40° F. (5° C).
Important:
Do not operate the topdresser during
temperatures of -7° C (20° F) or lower.
1. Increase the belt tension by adjusting spring
compression to 101 mm (4 inches); refer to
Tensioning the Conveyor-Belt Chain (page
2. Run belt before loading the hopper with material
to assure that belt system moves freely.
Important:
If belt/drive roller slip, damage to
belt or roller may occur.
Important:
Before operating the machine during
warm weather, adjust the belt tension to 112 mm
(4-7/16 inches) spring compression.
