Tractor Ballast; Tractor Safety Devices - Alamo PA92 Operator's Manual

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. For units which have the ability to operate
on either side of the tractor, these requirements must also be met for the right side tire when the boom is
extended to the left side as described above. 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. NOTE: All factory mounted units are tested and meet the ballast requirement before shipment;
further testing is not required unless the unit is operated in a manner other than what is considered standard
operating conditions.
For additional information on properly ballasting the tractor, refer to Alamo Industrial Tractor and Mower
Stability Pamphlet P/N #02959010
If the unit is operated on slopes greater than 5°,
additional counterweight
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

3.5 Tractor Safety Devices

If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with
proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of
the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor
warning signals are obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were
removed for access to connect, service, or repair the tractor or implement.
