Combine Harvester Service & Repair Manuals

A combine harvester does three jobs in a single pass — reaping, threshing and winnowing — through some of the most complex machinery on any farm. When harvest is on the clock, the right manual is the difference between a quick fix and a lost day.

What these manuals cover: the header and cutting platform, the threshing cylinder or rotor and concave, the separation and cleaning system (straw walkers or rotors, sieves and the cleaning fan), grain handling (augers, elevators and the grain tank), the feeder house, plus the hydraulics, drive and electrical — with the clearances, settings and torque data that keep losses low.
