John Deere 624J - Manual (Page 32)

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 5,000-ft. (1525 m)
altitude for the 444J and the 544J and up to 10,000-ft. (3050 m)
altitude for the 624J. Gross power is without cooling fan. Specifications and design subject to change without notice. Wherever applicable, specifications are in accordance with ISO standards.
Except where otherwise noted, these specifications are based on units with standard equipment, ROPS cab, one optional rear counter-
weight, rear cast bumper/counterweight, 20.5R25 tires, full fuel tank, and 175-lb. (79 kg) operator.
