MASSEY-HARRIS 101/102 Senior or Nuffield M-3?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 101/102 Senior has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the M-3 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Nuffield M-3 suits road haulage better on this data: 40% (8.0 km/h / 5.0 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 Nuffield M-3 is 20% heavier (371 kg / 818 lb) than the MASSEY-HARRIS 101/102 Senior (both unladen weight, as stated by the source).
- The Nuffield M-3 has 40% more top speed (8.0 km/h / 5.0 mph) than the MASSEY-HARRIS 101/102 Senior (both top speed forward, as stated by the source).
- The Nuffield M-3 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): 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 101/102 Senior has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the M-3 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.
