International Harvester 664 or International Harvester 784?
Which should you choose?
On performance, every comparable figure that differs favours the International Harvester 664: hydraulic flow. It is also ahead on top speed. On features, the International Harvester 784 is ahead on drive.
- The International Harvester 664 suits loader and hydraulic implement work better on this data: 19% (7.2 L/min / 1.9 gpm) more hydraulic flow.
- The International Harvester 664 suits road haulage better on this data: 20% (5.0 km/h / 3.1 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.

| Which is newer, and what about parts? | 1972–1973 | 1977–1981 | Ahead (a fact, not an advantage)The International Harvester 784 is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- The International Harvester 664 has 19% more hydraulic flow (7.2 L/min / 1.9 gpm) than the International Harvester 784 (both pump flow, as stated by the source).
- The International Harvester 664 is 14% heavier (322 kg / 710 lb) than the International Harvester 784 (both unladen weight, as stated by the source).
- The International Harvester 664 has 20% more top speed (5.0 km/h / 3.1 mph) than the International Harvester 784 (both top speed forward, as stated by the source).
- The International Harvester 784 is available with four-wheel drive; the International Harvester 664 is two-wheel drive (as stated by the sources).
- The International Harvester 784 is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts.
- 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 PTO speeds: the same speeds (540, 1000 rpm).
- 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.
