MASSEY-HARRIS Pacer 16 or SOMECA SOM-20 D?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Pacer 16 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-20 D has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The MASSEY-HARRIS Pacer 16 suits loader and hydraulic implement work better on this data: 52% (3.9 L/min / 1.0 gpm) more hydraulic flow.
- The SOMECA SOM-20 D suits road haulage better on this data: 62% (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 MASSEY-HARRIS Pacer 16 is 21% heavier (177 kg / 390 lb) than the SOMECA SOM-20 D (both unladen weight, as stated by the source).
- The SOMECA SOM-20 D has 100% more forward gears (3 gears) than the MASSEY-HARRIS Pacer 16 (both forward gears, as stated by the source).
- The SOMECA SOM-20 D has 62% more top speed (8.0 km/h / 5.0 mph) than the MASSEY-HARRIS Pacer 16 (both top speed forward, as stated by the source).
- Even on PTO speeds: the same speeds (540 rpm).
- 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 Pacer 16 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the SOM-20 D 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.
