160–180 SAE NET HORSEPOWER
H
624H WH 644H WH
Net engine power is with standard equipment including air cleaner, exhaust
system, alternator, and cooling fan,at standard conditions per SAE J1349
and DIN 70 020, using No.2-D fuel at 35 API gravity. No derating is required
up to 10,000-ft. (3050 m) altitude.Gross power is without cooling fan.
Specifications and design subject to change without notice.Wherever applicable, specifica-
tions are in accordance with SAE standards. Except where otherwise noted,these specifica-
tions are based on units with all standard equipment, waste handler complete protection
package, high-lift booms,ROPS cabs,full fuel tanks, and 175-lb.(79 kg) operators; 624J unit
with 20.5-25 solid rubber tires; and 644J unit with 23.5-25 solid rubber tires.
