Ford 4830 (A) or VALMET 455/445-4?
Which should you choose?
The figures split: the Ford 4830 (A) is ahead on hydraulic flow; the VALMET 455/445-4 is ahead on 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 Ford 4830 (A) has 12% more hydraulic flow (3.7 L/min / 1.0 gpm) than the VALMET 455/445-4 (both pump flow, as stated by the source).
- The VALMET 455/445-4 has 33% more lift (653 kg / 1,440 lb) than the Ford 4830 (A) (both lift at the hitch ends, 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 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, maximum permissible mass, a creeper range and PTO independence.
