ALLIS-CHALMERS WD-45 or Warchalowski WT-42 A?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the WD-45 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the WT-42 A has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Warchalowski WT-42A suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.
- The Warchalowski WT-42A suits road haulage better on this data: 50% (9.7 km/h / 6.0 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-42A has 100% more forward gears (4 gears) than the ALLIS-CHALMERS WD-45 (both forward gears, as stated by the source).
- The Warchalowski WT-42A has 50% more top speed (9.7 km/h / 6.0 mph) than the ALLIS-CHALMERS WD-45 (both top speed forward, as stated by the source).
- The Warchalowski WT-42A is available with four-wheel drive; the ALLIS-CHALMERS WD-45 is two-wheel drive (as stated by the sources).
- The Warchalowski WT-42A is newer: production began 11 years later. We hold no parts-availability data, so there is no call on parts.
- 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 weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- Not comparable on power at the PTO shaft: the WD-45 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the WT-42 A 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, PTO speeds and PTO independence.
