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.

Ford 3400–4500 Common Problems This Manual Covers
Select-O-Speed creeps or shifts hard
A Select-O-Speed that drifts in neutral or will not take a shift under load gets blamed on the transmission long before anyone checks how it is being operated. The Operation section gives the starting, shifting and P.T.O. sequence for Select-O-Speed tractors and what each control position actually commands.
Manual Section: Operating Select-O-Speed Tractors And P.T.O. p. 18Three-point hitch will not hold load
A lift that sinks under a mounted implement is usually blamed on the pump when fluid level, control setup or a drifting relief setting is the real cause. The manual gives the hydraulic system relief valve setting as 2500 psi, so you can confirm the system is making pressure before anything comes apart.
Manual Section: Operating Hydraulic Lift System p. 98Long cranking on a cold morning
Worn plugs and closed-up breaker points show up first as hard starting and a rough idle. Specifications lists the spark plug gap as 0.023-0.027 inch and the distributor point gap as 0.022-0.028 inch, so a feeler gauge settles it before you start buying ignition parts.
Manual Section: Specifications p. 97Valve clatter and lost pull
Noisy tappets and a soft-running engine often trace to valve clearance drifting after the first working hours. The Specifications section lists the go and no-go clearances: 0.014 inch go and 0.016 inch no-go on intake, 0.017 inch go and 0.019 inch no-go on exhaust.
Manual Section: Specifications p. 96Running hot during heavy loader work
Overheating in summer usually starts with a tired radiator cap or a fan belt slipping on the pulleys. The manual calls for a 7 psi radiator cap and fan belt deflection of 1/4 to 1/2 inch, both of which take minutes to check before the gauge climbs again.
Manual Section: General Maintenance p. 97Steering goes heavy on front-loaded tractors
Power steering that turns stiff or noisy is often nothing more than a filter nobody has changed. The manual sets the power steering oil filter change interval at 600 hours, and the hydraulic lift control pages show where the service point sits.
Manual Section: Hydraulic Lift System Controls p. 12Rear wheels spin with loaded bucket
Lost traction and a light front end come down to ballast and wheel tread rather than a worn clutch. The Operation section covers tractor weighting, wheel tread settings and use of the differential lock, so the tires are planted before you suspect the drivetrain.
Manual Section: Tractor Weighting p. 34Frequently Asked Questions
Which tractors does this manual cover?
Ford industrial tractors 3400, 3500, 3550, 4400 and 4500. It is Ford publication 42340040, 107 pages in English, with coverage for Select-O-Speed, manual shift and power reversing transmissions.
Is this an operator manual or a shop manual?
It is the operator manual: controls, operation, lubrication and maintenance, and specifications, plus pre-delivery and 50-hour service. It does not carry full teardown and overhaul procedures. The Specifications section starts at page 69 and holds the figures you check most often. p. 69
Does it cover both Select-O-Speed and manual shift models?
Yes. The Controls and Instruments section handles Select-O-Speed transmission and P.T.O. controls from page 8, then manual shift and power reversing transmission and P.T.O. controls on the pages that follow. Operation gives the driving and P.T.O. procedure for each type. p. 8
Are tune-up figures like plug gap included?
Yes. Specifications gives the spark plug gap as 0.023-0.027 inch, along with distributor point gap, intake and exhaust valve clearance go/no-go figures, radiator cap pressure and fan belt deflection. p. 97
What format is this Ford 3400–4500 manual in?
You download the Operator Manual yourself: 107 pages, searchable PDF, available immediately. Keep a copy on every device you use.
Is this Ford 3400–4500 manual print-friendly?
