ALLIS-CHALMERS RUMELY-DoAll or Hürlimann 4 T 18Z?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the RUMELY-DoAll has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4 T 18Z has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Hürlimann 4 T 18Z suits road haulage better on this data: 150% (9.0 km/h / 5.6 mph) more top speed.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “similar machines”. 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 ALLIS-CHALMERS RUMELY-DoAll is 12% heavier (179 kg / 395 lb) than the Hürlimann 4 T 18Z (both unladen weight, as stated by the source).
- The Hürlimann 4 T 18Z has 150% more top speed (9.0 km/h / 5.6 mph) than the ALLIS-CHALMERS RUMELY-DoAll (both top speed forward, as stated by the source).
- Even on forward gears (both forward gears, as stated by the source): fewer than 2 gears apart.
- Even on drive: all two-wheel drive.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- Not comparable on power at the PTO shaft: the RUMELY-DoAll has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4 T 18Z 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, PTO speeds and PTO independence.
