International Harvester 744 or SOMECA 640 (TD)?
Which should you choose?
On performance, every comparable figure that differs favours the International Harvester 744: three-point lift.
- The International Harvester 744 suits loader and hydraulic implement work better on this data: 58% (1,070 kg / 2,359 lb) more three-point lift.
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 744 has 58% more lift (1,070 kg / 2,359 lb) than the SOMECA 640 (TD) (both lift at the hitch ends, as stated by the source).
- The International Harvester 744 is 45% heavier (955 kg / 2,105 lb) than the SOMECA 640 (TD) (both unladen weight, as stated by the source).
- Even on power at the PTO shaft (both power at the PTO, claimed): the difference is under the 10% threshold for claimed figures, too small to call.
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on drive: every machine is available with four-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.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, maximum permissible mass, a creeper range and PTO independence.
