Part of the John Deere Repair Manuals.
Wrenching on a John Deere 1350, 1550, 1750, 1850, 1850N, 1950, or 1950N? This 666-page technical manual PDF (OEM #TM4437) is the factory shop reference for the whole tractor line, engine through operator's cab. You get complete engine and power train teardowns: single- and dual-stage clutches, Hi-Lo shift unit, creeper transmission, differential, final drives, and all three PTO setups, with exploded views and factory torque tables throughout. Hydraulics, steering, and brakes get the same treatment, from rockshaft and selective control valve service to power steering rebuilds. Set the oil pan drain plugs to 135 Nm (100 ft-lb) and check braking pressure against the 14000 kPa (140 bar; 2030 psi) spec. Your tractor is down; forum guesses won't lift it. Multi-level bookmarks jump you straight to any system, and the PDF opens on any laptop, tablet, or phone in the shop.
