The John Deere 4430 is a 125-PTO-hp Generation II row-crop tractor built from 1973 through 1977. It remains a strong fit for substantial PTO, tillage, and hay work when its transmission and hydraulic systems have been properly maintained.

John Deere 4430 specifications

What the 4430 is used for

The 4430 has enough power for heavy mowing, baling, planting, and moderate-to-large tillage work. Its closed-center hydraulic system and available remote valves also make it useful with hydraulic implements and loaders.

A Sound-Gard cab tractor is especially attractive for long workdays, while open-operator or ROPS versions can suit buyers who prioritize simplicity. Select tire size, ballast, and drive configuration to match the work rather than relying on horsepower alone.

Why the John Deere 4430 stands out

The 4430 combines Deere's turbocharged 6.6L diesel with proven Generation II features: closed-center hydraulics, planetary final drives, wet disc brakes, independent PTO, and several transmission choices. It was built in Waterloo, Iowa, and became one of the defining large row-crop tractors of its era.

Buying a used John Deere 4430

Identify the transmission before purchase and test every range, gear, reverser function, PTO, hydraulic remote, three-point hitch, and differential lock at operating temperature. Inspect the cab for corrosion and electrical issues, and check the engine for blow-by, cooling-system pressure problems, and evidence of neglected oil or hydraulic service.
