ALLIS-CHALMERS 175 or Eicher Mammut 3020 HR A?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 175 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Mammut 3020 HR A has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Eicher Mammut 3020 HR A suits loader and hydraulic implement work better on this data: 59% (14.4 L/min / 3.8 gpm) more hydraulic flow.
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 Eicher Mammut 3020 HR A has 59% more hydraulic flow (14.4 L/min / 3.8 gpm) than the ALLIS-CHALMERS 175 (both pump flow, as stated by the source).
- The ALLIS-CHALMERS 175 is 15% heavier (473 kg / 1,043 lb) than the Eicher Mammut 3020 HR A (both unladen weight, as stated by the source).
- The Eicher Mammut 3020 HR A is available with four-wheel drive; the ALLIS-CHALMERS 175 is two-wheel drive (as stated by the sources).
- Transmissions differ in kind: the ALLIS-CHALMERS 175 has 8 forward gears and the Eicher Mammut 3020 HR A is stepless (CVT) — not called.
- Even on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call.
- PTO speeds differ: the ALLIS-CHALMERS 175 540 rpm and the Eicher Mammut 3020 HR A 1000 rpm — each offers a speed the other does not; which matters depends on the implement.
- 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 175 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Mammut 3020 HR 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, three-point lift, maximum permissible mass, a creeper range and PTO independence.
