International Harvester D-430 or Volvo T-25?
Which should you choose?
On performance, every comparable figure that differs favours the Volvo T-25: hydraulic flow.
- The Volvo T-25 suits loader and hydraulic implement work better on this data: 54% (8.3 L/min / 2.2 gpm) more hydraulic flow.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “similar machines”. 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 Volvo T-25 has 54% more hydraulic flow (8.3 L/min / 2.2 gpm) than the International Harvester D-430 (both pump flow, 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 weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- Even on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call.
- 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 three-point lift: the D-430: lift at the hitch ends, as stated by the source (Traktorenlexikon, “McCormick D-430 Farmall”); the T-25: lift at an unstated point, as stated by the source (Traktorenlexikon, “Volvo T 25”) — not the same quantity, basis and condition.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range and PTO independence.
