Hürlimann D-550 Hydrostat or SOMECA 1380 (TD)?
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 1380 (TD) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The SOMECA 1380 (TD) suits loader and hydraulic implement work better on this data: 70% (2,034 kg / 4,484 lb) more three-point lift.
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 SOMECA 1380 (TD) has 70% more lift (2,034 kg / 4,484 lb) than the Hürlimann D-550 Hydrostat (both lift at the hitch ends, as stated by the source).
- The SOMECA 1380 (TD) is 13% heavier (575 kg / 1,268 lb) than the Hürlimann D-550 Hydrostat (both unladen weight, as stated by the source).
- The Hürlimann D-550 Hydrostat offers 540 rpm at the PTO, which the SOMECA 1380 (TD) does not (as stated by the sources).
- The SOMECA 1380 (TD) is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts.
- Even on hydraulic flow (both pump flow, as stated by the source): the difference is under the 10% threshold, too small to call.
- Transmissions differ in kind: the Hürlimann D-550 Hydrostat is stepless (CVT) and the SOMECA 1380 (TD) has 12 to 24 forward gears — not called.
- Even on top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on drive: every machine is available with four-wheel drive.
- 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 1380 (TD) 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, maximum permissible mass, a creeper range and PTO independence.
