Net engine power is with standard equipment including air 
cleaner, exhaust system, alternator, and cooling fan, at standard conditions per SAE J1349 and DIN 6270B, using No. 2-D 
fuel at 35 API gravity. No derating is required up to 10,000-ft. 
(3050 m) altitude.
Specifications and design subject to change without notice. Wherever applicable, specifications are in accordance with SAE standards. Except where otherwise noted, these specifications are based on a unit with standard equipment, modular ROPS/FOPS cab 
with air conditioning, 165-in. (4191 mm) semi-U blade with standard cutting edges, landfill package, full fuel tank, and 175-lb. 
(79 kg) operator.
