Part of the New Holland Repair Manuals.
If it says 1037 on the side of your bale wagon, this New Holland 1037 service manual PDF applies: 164 factory pages under OEM ID 47816352, running from the PTO drive shaft through every hydraulic circuit on the machine. Hydraulic schematics map the bale loading, storing, and unloading circuits, so a drifting first table cylinder or stalled push-off feet can be traced valve by valve. Full teardown, inspection, and bench-test procedures cover both the Parker Hannifin and Cessna pumps, with exploded views of the spring-centered control valves and orbit motor. Before resealing a cylinder, check piston grooves against the 0.38 mm (0.015 in) wear limit and the clevis pin hole against its 2.4 mm (3/32 in) allowance. Hay down and the table won't lift: a bad afternoon. Bookmarks and a live text layer take you straight to the circuit at fault before the weather turns.
