Part of the John Deere Repair Manuals.
This John Deere GT235 Technical Manual PDF (TM1756) packs 584 pages of factory service data, and it covers the GT225, GT235E, and GT245 garden tractors too, so one download handles the whole line. Inside: complete electrical schematics with circuit-by-circuit diagnosis for the power, cranking, ignition, and charging systems, plus full teardown procedures for the hydrostatic transaxle, charge pump, and piston pump. You also get dedicated engine sections for the Kohler, Briggs and Stratton, and Kawasaki FH580V and FH601V powerplants, from compression tests to crankshaft oil seals. Gap the GT235 plugs at 0.76 mm, torque them to 22 N-m, and check the electric PTO clutch for 2.4 to 2.7 ohms before you condemn it. Your tractor is down and mowing season won't wait. Bookmarked with keyword search built in; jump straight to the spec and start wrenching.
