MASSEY-HARRIS Pony 820 or Warchalowski WT 20?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Pony 820 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the WT 20 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Warchalowski WT 20 suits road haulage better on this data: 67% (10.0 km/h / 6.2 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 MASSEY-HARRIS Pony 820 is 19% heavier (165 kg / 364 lb) than the Warchalowski WT 20 (both unladen weight, as stated by the source).
- The Warchalowski WT 20 has 67% more top speed (10.0 km/h / 6.2 mph) than the MASSEY-HARRIS Pony 820 (both top speed forward, as stated by the source).
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- 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 Pony 820 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the WT 20 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.
