Fiat 451 C or ZETOR Super-P?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 451 C has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super-P has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Fiat 451 C suits loader and hydraulic implement work better on this data: 32% (4.0 L/min / 1.1 gpm) more hydraulic flow.
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 Fiat 451 C has 32% more hydraulic flow (4.0 L/min / 1.1 gpm) than the ZETOR Super-P (both pump flow, as stated by the source).
- The ZETOR Super-P is 79% heavier (1,985 kg / 4,376 lb) than the Fiat 451 C (both unladen weight, as stated by the source).
- The ZETOR Super-P has 50% more top speed (5.0 km/h / 3.1 mph) than the Fiat 451 C (both top speed forward, as stated by the source).
- 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 PTO speeds: the same speeds (540 rpm).
- Even on drive: the same running gear.
- 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 451 C has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super-P 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.
