John Deere 444J - Manual (Page 28)

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 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 a unit with all standard equipment, ROPS cab, full fuel tank, and
175-lb. (79 kg) operator; a 444J unit with 17.5 R 25 tires; and 544J and 624J units with 20.5 R 25 tires.
