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.
