Allgaier R18 or ALLIS-CHALMERS Modell-C?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the R18 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Modell-C has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Allgaier R18 suits road haulage better on this data: 58% (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 Allgaier R18 is 60% heavier (602 kg / 1,327 lb) than the ALLIS-CHALMERS Modell-C (both unladen weight, as stated by the source).
- The Allgaier R18 has 58% more top speed (7.0 km/h / 4.3 mph) than the ALLIS-CHALMERS Modell-C (both top speed forward, as stated by the source).
- The Allgaier R18 is newer: production began 6 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): fewer than 2 gears apart.
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the R18 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Modell-C 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.
