Fiat 455 C or ZETOR Super-P?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 455 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 455 C suits loader and hydraulic implement work better on this data: 42% (5.3 L/min / 1.4 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 455 C has 42% more hydraulic flow (5.3 L/min / 1.4 gpm) than the ZETOR Super-P (both pump flow, as stated by the source).
- The ZETOR Super-P is 110% heavier (2,355 kg / 5,192 lb) than the Fiat 455 C (both unladen weight, as stated by the source).
- The ZETOR Super-P has 36% more top speed (4.0 km/h / 2.5 mph) than the Fiat 455 C (both top speed forward, as stated by the source).
- The Fiat 455 C is newer: production began 12 years later. We hold no parts-availability data, so there is no call on parts.
- 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.
- Not comparable on power at the PTO shaft: the 455 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.
