A Select-O-Speed that creeps in neutral, a loader that sags on the way down, a gas engine that will not fire until it is warm: these are the jobs this book heads off. It is Ford publication 42340040, the operator manual for the 3400, 3500, 3550, 4400 and 4500 industrial tractors, 107 pages.
Controls and Instruments walks the seat, light and engine controls, the brake and rear axle controls, and both the Select-O-Speed and manual shift or power reversing transmission and P.T.O. controls. Operation covers break-in, starting, the differential lock, the hydraulic lift system, lift linkage and drawbar, wheel tread settings and tractor weighting. Lubrication and Maintenance holds the service chart, fuels and lubricants, and storage; Specifications closes with pre-delivery and 50-hour service.
Guessing costs money: wrong lubricant in the rear axle, a filter left in past its interval, a pump pulled twice. Work from the book and the tractor is back in the field before the weather turns.
