SOMECA SOM-20 D or Warchalowski WT-21?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the SOM-20 D has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the WT-21 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Warchalowski WT-21 suits road haulage better on this data: 33% (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 Warchalowski WT-21 has 33% more top speed (7.0 km/h / 4.3 mph) than the SOMECA SOM-20 D (both top speed forward, as stated by the source).
- The Warchalowski WT-21 has an independent PTO; the SOMECA SOM-20 D’s is dependent (stops with the clutch).
- The Warchalowski WT-21 is newer: production began 12 years later. We hold no parts-availability data, so there is no call on parts.
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- 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 SOM-20 D has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the WT-21 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 and a creeper range.
