Somewhere in the 882 pages of this New Holland Workmaster 45, Workmaster 55 service manual PDF (OEM 84269847) is the job you are staring at right now, whether that is a slipping power coupling clutch or a dead lighting circuit. Hydraulic schematics trace the open center system from pump through the mechanical remote valve, and wiring diagrams map the electrical power and lighting circuits on both tractors. Troubleshooting charts walk each fault from symptom to cause, then hand you the repair procedure for the transmission, rear PTO, front axle, brakes and steering. Refill the transmission and rear axle with 25.0 l (6.6 US gal), then set the pressure regulating valve between 17499 and 18002 kPa (2538 to 2611 psi) before you button up the lift housing. Hay does not wait while a tractor sits. Buy this bookmarked, keyword-searchable PDF once and it is yours for the life of the machine.
