Hürlimann D-550 Hydrostat or VALMET 1502?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D-550 Hydrostat has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 1502 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The VALMET 1502 suits loader and hydraulic implement work better on this data: 23% (670 kg / 1,477 lb) more three-point lift.
- The VALMET 1502 suits road haulage better on this data: 11% (3.0 km/h / 1.9 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 VALMET 1502 has 23% more lift (670 kg / 1,477 lb) than the Hürlimann D-550 Hydrostat (both lift at the hitch ends, as stated by the source).
- The VALMET 1502 is 74% heavier (3,170 kg / 6,989 lb) than the Hürlimann D-550 Hydrostat (both unladen weight, as stated by the source).
- The VALMET 1502 has 11% more top speed (3.0 km/h / 1.9 mph) than the Hürlimann D-550 Hydrostat (both top speed forward, as stated by the source).
- Transmissions differ in kind: the Hürlimann D-550 Hydrostat is stepless (CVT) and the VALMET 1502 has 16 forward gears — not called.
- Even on PTO speeds: the same speeds (540, 1000 rpm).
- Even on drive: every machine is available with four-wheel drive.
- 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-550 Hydrostat has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 1502 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.
