OPERATION
3.3 Tractor Horsepower
The horsepower required to operate the mower depends on several operating factors including the vegetation
to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most
mowing conditions, the SE10-4 mower requires a tractor with a minimum of 40 HP and the SE15-4 mower
requires a tractor with a minimum of 50 HP. Operating the mower with a tractor that does not have adequate
power may damage the tractor engine. Exceeding 130 HP may cause mower damage by overpowering the
unit in heavy cutting conditions.
3.2 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. Never operate the tractor PTO
with the PTO master shield missing or in the raised position. OPS-U- 0004
3.4 Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end
weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the
front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front
weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005
