New Holland Workmaster 45 & Workmaster 55 Tractor PDF Repair Service Manual (Publication 84269847)
The Workmaster 45 and Workmaster 55 tractors are built for livestock farms, landscaping, property maintenance and light agricultural work where reliability and simple operation are essential.

Publication 84269847 is the official OEM repair service manual that guides technicians through complete disassembly, inspection, testing and reassembly using factory-approved procedures and specifications.
