New Holland part number 87477124 is the operator manual for the Boomer 3040, 3045 and 3050 with 12x12 gear transmission, 123 pages of tractor operation you can keep on the bench. Wiring diagrams run a solid block near the back, tracing harness routing from battery to instrument cluster so a dead dash lamp gets traced, not guessed at. Controls and instruments, engine starting, three-point hitch and remote hydraulics fill the operation chapter, while the lubrication section lays out service intervals and hardware tightening torques. Transmission refill runs 35.2 L (9.3 gal), the Boomer 3040 cooling system holds 7.9 liters (8.3 U.S. qts), and the system relief valve is set at 172 bar (2500 PSI). Hay is down, nobody knows the fill capacity, and checking the transmission oil before the mower deck goes on should not mean guesswork. Bookmarked and text searchable, this file hands the number over in seconds and gets your tractor running again before the weather turns.
