WHITE 2-50 or ZETOR 4511?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 2-50 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4511 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The WHITE 2-50 suits loader and hydraulic implement work better on this data: 13% (2.7 L/min / 0.7 gpm) more hydraulic flow.
- The WHITE 2-50 suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.
- The WHITE 2-50 suits road haulage better on this data: 20% (5.0 km/h / 3.1 mph) more top speed.
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 WHITE 2-50 has 13% more hydraulic flow (2.7 L/min / 0.7 gpm) than the ZETOR 4511 (both pump flow, as stated by the source).
- The WHITE 2-50 has 20% more top speed (5.0 km/h / 3.1 mph) than the ZETOR 4511 (both top speed forward, as stated by the source).
- The WHITE 2-50 is available with four-wheel drive; the ZETOR 4511 is two-wheel drive (as stated by the sources).
- The WHITE 2-50 is newer: production began 8 years later. We hold no parts-availability data, so there is no call on parts.
- 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 PTO speeds: the same speeds (540 rpm).
- Even on PTO independence: every PTO is independent.
- Not comparable on power at the PTO shaft: the 2-50 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 4511 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the 2-50: lift through the full range 610 mm behind the ends, as stated by the source (Traktorenlexikon, “White 2-50”); the 4511: lift at the hitch ends, as stated by the source (Traktorenlexikon, “Zetor 4511”) — 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 and a creeper range.
