Part of the John Deere Repair Manuals.
Whether the hydrostatic transaxle takes the right oil, how the operator presence interlock is supposed to behave, which grease belongs in a deck spindle: questions like these get settled once, by the factory. This John Deere 1445 technical manual PDF, Deere publication TM1806, runs 834 pages and covers five front mower models from the 1420 through the 1565, gas and diesel alike. Wiring diagrams trace the interlock circuits from seat switch to PTO switch to starter, hydraulic schematics lay out the lift and drive circuits line by line, and repair procedures fill well over half the book. Set your alternator belt deflection between 10 and 15 mm, then pull the crankshaft main bearing cap screws to 79 N·m (58 lb-ft), straight from the spec tables. Nobody to ask when it's just you and a machine older than the dealership's records? Bookmarked and text-searchable, this PDF answers, and the mower runs again.
