VALMET 903/903-4 or ZETOR 9520/9540?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 903/903-4 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 9520/9540 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The ZETOR 9520/9540 suits loader and hydraulic implement work better on this data: 60% (1,730 kg / 3,814 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 ZETOR 9520/9540 has 60% more lift (1,730 kg / 3,814 lb) than the VALMET 903/903-4 (both lift at the hitch ends, as stated by the source).
- The ZETOR 9520/9540 offers 1000 rpm at the PTO, which the VALMET 903/903-4 does not (as stated by the sources).
- The ZETOR 9520/9540 is newer: production began 13 years later. We hold no parts-availability data, so there is no call on parts.
- Even on hydraulic flow (both pump flow, as stated by the source): the difference is under the 10% threshold, 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 independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the 903/903-4 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 9520/9540 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, maximum permissible mass and a creeper range.
