New Holland Boomer 33 & Boomer 37 Compact Tractor PDF Repair Service Manual (Tier 4B Final)

Compact tractors often perform the widest variety of jobs on a property—from loader work and mowing to grading, landscaping and snow removal. The New Holland Boomer 33 and Boomer 37 were engineered to deliver the maneuverability of a compact tractor while offering the hydraulic capacity, hydrostatic transmission performance and operator comfort expected from larger utility machines. Available in both ROPS and factory cab configurations, the Boomer 37 is designed for year-round operation, making accurate repair procedures essential when maintaining hydraulic, electrical and drivetrain systems.

This OEM Factory Repair Service Manual (Publication No. 47941899) is the official workshop reference for Boomer 33, Boomer 37 ROPS and Boomer 37 Cab Tier 4B (Final) tractors. Instead of relying on generic repair methods, technicians can follow factory-approved disassembly sequences, inspection limits, hydraulic test procedures and electrical diagnostics developed specifically for these compact tractors. The manual was published in March 2016 (2nd Edition) and replaces publication 47700453.
