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

Designed as the "all-rounder" of the New Holland tractor lineup, the T6 Series bridges the gap between compact utility tractors and large row-crop machines. A single tractor may spend the morning feeding livestock with a front loader, the afternoon powering a round baler and the evening transporting grain trailers on public roads. That constant change of workload places unique demands on the transmission, front axle, hydraulic pump and electronic hitch management. This OEM Factory Repair Service Manual gives technicians the same technical information used by New Holland dealerships to restore these systems to factory operating standards.

Publication 47665859 covers the New Holland T6.120, T6.140, T6.150, T6.155, T6.160, T6.165, T6.175 together with the T6.140, T6.150 and T6.160 Auto Command tractors. Every chapter follows a logical workshop sequence—from fault diagnosis and hydraulic testing to disassembly, inspection, measurement, calibration and final performance checks—making it suitable for complete rebuilds as well as everyday repairs. The manual contains 3,823 searchable pages in a fully bookmarked PDF with OEM wiring diagrams, hydraulic schematics and detailed exploded illustrations.

Engineered for Workshops That Maintain Working Tractors

The T6 Series is often the highest-hour tractor on livestock and mixed farming operations because it performs a wider range of daily jobs than larger field tractors. This factory manual reflects that reality by providing systematic diagnostic procedures that help technicians identify hydraulic, transmission and electronic faults before unnecessary parts are replaced. Following the OEM repair sequence improves repair accuracy and helps return the tractor to dependable field service more quickly. :contentReference[oaicite:2]{index=2}
