John Deere Modell-M or MASSEY-HARRIS 101/102 Junior?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Modell-M has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 101/102 Junior has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The MASSEY-HARRIS 101/102 Junior suits road haulage better on this data: 25% (4.0 km/h / 2.5 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 John Deere Modell-M is 17% heavier (258 kg / 569 lb) than the MASSEY-HARRIS 101/102 Junior (both unladen weight, as stated by the source).
- The MASSEY-HARRIS 101/102 Junior has 25% more top speed (4.0 km/h / 2.5 mph) than the John Deere Modell-M (both top speed forward, as stated by the source).
- The John Deere Modell-M is newer: production began 8 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): 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-M has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 101/102 Junior 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.
