mowing conditions, the FN180/120 NITRO mower requires a tractor with a minimum of 70 HP. Operating the
mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding 100 HP
for a 540 RPM drive and 140 HP for a 1000 RPM drive may cause mower damage by overpowering the unit in
heavy cutting conditions.
2.1 ROPS and Seat Belt
The tractor must be equipped with a Factory Cab and seat belt to protect the operator from falling from the
tractor and being crushed or run over by the tractor and/or implement resulting in serious injury or death. Only

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
