New Holland TM120, TM130, TM140, TM155 TM175 TM190 Tractor Pdf Repair Service Manual (p. Nb. 6045511102)

New Holland TM120, TM130, TM140, TM155, TM175 & TM190 Tractor PDF Repair Service Manual (Publication No. 6045511102)

When a tractor is expected to pull deep tillage equipment at dawn, operate a large square baler through the afternoon and finish the day hauling loaded grain trailers, reliability becomes just as important as horsepower. The New Holland TM120, TM130, TM140, TM155, TM175 and TM190 were engineered for professional farming businesses that demand continuous performance throughout the season. These tractors combine powerful drivetrains, electronically controlled hydraulics and heavy-duty chassis components capable of handling intensive field operations. As working hours increase, accurate repair procedures become essential for maintaining productivity.

This OEM Factory Repair Service Manual (Publication No. 6045511102) delivers dealership-level workshop information, enabling technicians to diagnose, repair, calibrate and overhaul every major tractor system according to original New Holland specifications.

Rather than providing simple maintenance instructions, this manual follows the same structured repair sequence used in professional service workshops. It helps identify the root cause of faults before dismantling major assemblies, reducing unnecessary parts replacement while improving repair accuracy.

Created for Heavy Draft Farming and High-Capacity PTO Operations

The TM Series was developed for modern mixed farms, grain operations and agricultural contractors that rely on one tractor to perform multiple demanding tasks throughout the year. Depending on the model, these tractors produce approximately 120–190 engine horsepower and are designed to work with wide cultivators, air seeders, heavy ploughs, slurry tankers, forage wagons and high-capacity balers. Their electronically managed hydraulic system delivers strong oil flow for multiple remote valves, while the heavy-duty rear linkage provides excellent lifting capability for large mounted implements. The spacious cab, responsive steering and mechanical front-wheel drive help operators maintain productivity during long working days.

Machine Information

What Makes This Workshop Manual Different?

The TM Series integrates hydraulic, mechanical and electronic systems that work together under heavy field loads. A transmission warning may actually originate from hydraulic pressure loss, while poor hitch response could be caused by electronic calibration rather than mechanical failure. This factory manual explains the correct diagnostic sequence, helping technicians solve problems efficiently instead of replacing expensive components unnecessarily.

• Perform powershift transmission diagnostics before gearbox removal.
• Calibrate transmission clutch packs following overhaul procedures.
• Measure hydraulic system pressure to identify pump, valve or load-sensing faults.
• Repair the electronic rear hitch control system for accurate implement operation.
• Inspect MFWD axle hubs, differential gears and final drives after prolonged heavy draft work.
• Restore PTO performance for forage harvesters, balers and slurry equipment.
• Troubleshoot steering hydraulics to eliminate heavy steering and poor responsiveness.
• Use OEM electrical wiring diagrams to diagnose electronic control modules, charging and lighting circuits.
• Inspect braking systems before high-speed road transport.
• Verify torque settings, wear limits and adjustment values before returning the tractor to service.
