International Harvester D-320 Farmall or International Harvester F-137 D?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D-320 Farmall has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the F-137 D has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The International Harvester D-320 Farmall suits road haulage better on this data: 11% (2.0 km/h / 1.2 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 International Harvester D-320 Farmall is 21% heavier (228 kg / 503 lb) than the International Harvester F-137 D (both unladen weight, as stated by the source).
- The International Harvester D-320 Farmall has 11% more top speed (2.0 km/h / 1.2 mph) than the International Harvester F-137 D (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 a creeper range: every machine offers one.
- Even on PTO independence: every PTO is dependent.
- 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 D-320 Farmall has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the F-137 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, hydraulic flow, three-point lift, maximum permissible mass and PTO speeds.
