New Holland T6.120, T6.140, T6.150, T6.155, T6.160, T6.165 & T6.175 Tractor PDF Repair Service Manual

Not every tractor spends its life doing one job. The New Holland T6 Series was engineered to be the "workhorse" of modern mixed farming, equally capable of operating front loaders in livestock yards, powering PTO-driven forage equipment, towing trailers on the road and pulling cultivation implements in the field. Because these tractors transition between transport, draft work and hydraulic-intensive applications every day, technicians need repair information that covers far more than basic servicing. This OEM Factory Repair Service Manual delivers the same workshop procedures used by New Holland dealer technicians, allowing every major system to be diagnosed, repaired and calibrated to factory specifications.

Written for the New Holland T6.120, T6.140, T6.150, T6.155, T6.160, T6.165 and T6.175 tractor range, this manual explains complete disassembly, inspection, rebuilding and performance verification of mechanical, hydraulic and electronic systems. From transmission diagnostics to hitch calibration and electrical fault tracing, every chapter follows the official CNH workshop sequence, helping reduce repair time while improving reliability after major repairs. The manual contains 3,823 searchable pages with detailed illustrations, hydraulic schematics and OEM wiring diagrams.

Built for High-Hour Agricultural Machines

Unlike compact tractors that often perform seasonal work, T6 tractors commonly accumulate thousands of operating hours across multiple farming tasks each year. That high utilisation places continual stress on the driveline, hydraulics and electronic controls. This factory workshop manual provides structured diagnostic routines, measurement standards and calibration procedures that help technicians locate the root cause of failures quickly instead of replacing expensive components through trial and error.
