Hürlimann D-120 or UTB U 650/651?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D-120 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the U 650/651 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The UTB U 650/651 suits heavy draft work (ploughing, cultivating) better on this data: 37% (825 kg / 1,819 lb) heavier and four-wheel drive.
- The UTB U 650/651 suits road haulage better on this data: 35% (7.0 km/h / 4.3 mph) more top speed.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “the same stated configuration”. Measured figures are compared only with measured, claimed only with claimed, at the same test condition; differences within each figure’s tolerance are not called.

What does this mean in plain words?
- The UTB U 650/651 is 37% heavier (825 kg / 1,819 lb) than the Hürlimann D-120 (both unladen weight, as stated by the source).
- The UTB U 650/651 has 35% more top speed (7.0 km/h / 4.3 mph) than the Hürlimann D-120 (both top speed forward, as stated by the source).
- The UTB U 650/651 is available with four-wheel drive; the Hürlimann D-120 is two-wheel drive (as stated by the sources).
- No call on three-point lift: the sources do not state where the lift was measured, so the difference is not a reliable call.
- Even on forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- Not comparable on power at the PTO shaft: the D-120 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the U 650/651 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, maximum permissible mass, a creeper range and PTO independence.
