HELA L 25 or Schlüter DSU?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the L 25 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the DSU has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The HELA L 25 suits road haulage better on this data: 14% (2.4 km/h / 1.5 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 HELA L 25 is 16% heavier (300 kg / 661 lb) than the Schlüter DSU (both unladen weight, as stated by the source).
- The HELA L 25 has 14% more top speed (2.4 km/h / 1.5 mph) than the Schlüter DSU (both top speed forward, as stated by the source).
- The Schlüter DSU is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts.
- 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).
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the L 25 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the DSU 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, three-point lift, maximum permissible mass, a creeper range and PTO independence.
