OPERATION
Never operate the Tractor and Mower Unit without an OPS (Operators
Protective Structure) or Cab to prevent injury from objects thrown from
ground or from overhead trimming. Stop mowing if workers or passersby
are within 300 feet. (SBM-9)
3.3 Tractor Lighting and SMV Emblem
If the tractor will be operated near or traveled on a
public roadway it must be equipped with proper
warning lighting and a Slow Moving Vehicle (SMV)
emblem which are clearly visible from the rear of
the unit. Most tractor’s have different settings for
operating and transporting lighting. Refer to the
tractor operator’s manual for using the tractor’s
light switch and operating the turn signals.

3.4 Tractor Ballast
To ensure tractor stability when operating on flat surfaces the left rear tractor tire MUST exert a minimum
down force (weight) of 1500 lbs. on the ground when the tractor is on level ground, its boom is fully extended
and the mower head is horizontal and two feet above the ground. A tractor that does not meet this criteria is
DANGEROUS and should not be operated as upset of the unit can occur resulting in possible serious injury
and property damage.
If the unit is operated on slopes greater than 5,
additional counterweight will be required.
Operation of the unit on slopes greater than 11
percent (6.4 degrees) is not recommended under
any circumstances. On a tractor with a 96” outside
to outside tire spread, an 11 percent (6.4 degrees)
slope occurs when one rear tractor tire is about 8”
lower than the other rear tire. OPS-B- 0018_C
