The operation of any tractor can result in foreign qbjects thrown into the eyes, wh!ch can
result in severe eye damage. Always wear safety glasses or eye shields while operating
your tractor or performing any adjustments or repairs. We recommend a wide vision safety
mask over the spectacles or standard safety glasses.
TO SET PARKgNG BRAKE (See Fig. 9)
Your tractor is equipped with an operator presence sensing
switch. When engine is running, any attempt by the
operator to leave the seat without first setting the parking
brake will shut off the engine.
o Depress clutch/brake pedal intofull "BRAKE" position
and hold_
Place parking brake lever' in "ENGAGED" position and
release pressure from clutch/brake pedal. Pedal should
remain in "BRAKE" position., Make sure parking brake
will hold tractor secure.,

sition.,

NOTE; Failure to move throttle control to slow (,_)
position and allowing engine to idle before stopping may
cause engine to "backfire",
, Turn ignition key to "OFF" position and remove key.
Always remove key when leaving tractor to prevent
unauthorized use..

NOTE; Under certain conditions when tractor is standing
idle with the engine running, hot engine exhaust gases may
cause "browning" of grass. To eliminate this possibility,
always stop engine when stopping tractor on grass areas,
TO USE THROTTLE CONTROL (See Fig. 9)

Operating engine at Iess than full throttle reduces the
battery charging rate.
= Full throttle offers the best bagging and mower perfor-
mance.

The cutting height range is approximately 1-1/2" to 4'L The
heights are measured from the ground to the blade tip with
the engine not r'unning. These heights are approximate
and may vary depending upon soil conditions, height of
grass and types of grass being mowed.
The average lawn should be cut to approximately 2-1/2
inches during the cool season and to over 3 inches
dunng hot months. For healthier and better looking
lawns, mow often and after moderate growth.
° For best cutting performance, grass over 6 inches in
height should be mowed twice. Make the first cut
relatively high; the second to desired height.
