International Harvester 454 or SOMECA 500 Special (TD)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 454 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 500 Special (TD) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The International Harvester 454 suits loader and hydraulic implement work better on this data: 98% (21.3 L/min / 5.6 gpm) more hydraulic flow.
- The International Harvester 454 suits road haulage better on this data: 28% (7.0 km/h / 4.3 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 454 has 98% more hydraulic flow (21.3 L/min / 5.6 gpm) than the SOMECA 500 Special (TD) (both pump flow, as stated by the source).
- The International Harvester 454 is 14% heavier (261 kg / 575 lb) than the SOMECA 500 Special (TD) (both unladen weight, as stated by the source).
- The International Harvester 454 has 28% more top speed (7.0 km/h / 4.3 mph) than the SOMECA 500 Special (TD) (both top speed forward, as stated by the source).
- The International Harvester 454 offers 1000 rpm at the PTO, which the SOMECA 500 Special (TD) does not (as stated by the sources).
- The SOMECA 500 Special (TD) is available with four-wheel drive; the International Harvester 454 is two-wheel drive (as stated by the sources).
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- 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 454 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 500 Special (TD) 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.
