The four-cylinder diesel engine has a displacement of 3,318 cc and produces 60 hp, or 44.1 kW. At 3,570 mm long, 1,640 mm wide, 2,485 mm high, with a 2,010 mm wheelbase and 2,270 kg weight, the USpro 601 reaches a design top speed of 29.51 km/h. Ground clearance is around 400 mm.
The 8.3-20 front tyres paired with the notably wider 12.4-32 rear tyres show the classic layout of a two-wheel-drive standard tractor, where the rear axle carries the drawbar pull and the narrower front axle mainly steers. At 60 hp and just under 30 km/h top speed, the USpro 601 is a versatile tractor for medium-sized farms, covering both tillage and haulage around the yard.
When buying a standard tractor of this power class, check the condition of the tyres in these special sizes, play in the front-axle steering and the tightness of the hydraulic system feeding the three-point hitch. The clutch is also worth testing under load, as it ranks among the first wear parts on tractors of this class used for varied work, and mismatched tyre wear front to rear can point to a poorly aligned front axle.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
