ALLIS-CHALMERS Modell-WD or Fordson Dexta (957 E)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Modell-WD has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Dexta (957 E) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Fordson Dexta (957 E) suits loader and hydraulic implement work better on this data: 313% (14.7 L/min / 3.9 gpm) more hydraulic flow.
- The Fordson Dexta (957 E) suits road haulage better on this data: 44% (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 Fordson Dexta (957 E) has 313% more hydraulic flow (14.7 L/min / 3.9 gpm) than the ALLIS-CHALMERS Modell-WD (both pump flow, as stated by the source).
- The Fordson Dexta (957 E) has 44% more top speed (7.0 km/h / 4.3 mph) than the ALLIS-CHALMERS Modell-WD (both top speed forward, as stated by the source).
- The Fordson Dexta (957 E) is newer: production began 9 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 difference is under the 25% threshold, too small to call.
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the Modell-WD has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Dexta (957 E) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the Modell-WD: lift at an unstated point, as stated by the source (Traktorenlexikon, “Allis-Chalmers WD”); the Dexta (957 E): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Fordson Dexta”) — not the same quantity, basis and condition.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range, PTO speeds and PTO independence.
