Ford 4630 (A) or ZETOR Proxima 6421/6441?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 4630 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Proxima 6421/6441 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The ZETOR Proxima 6421/6441 suits loader and hydraulic implement work better on this data: 57% (16.8 L/min / 4.4 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 ZETOR Proxima 6421/6441 has 57% more hydraulic flow (16.8 L/min / 4.4 gpm) than the Ford 4630 (A) (both pump flow, as stated by the source).
- The ZETOR Proxima 6421/6441 is 12% heavier (340 kg / 750 lb) than the Ford 4630 (A) (both unladen weight, as stated by the source).
- The ZETOR Proxima 6421/6441 offers 1000 rpm at the PTO, which the Ford 4630 (A) does not (as stated by the sources).
- The ZETOR Proxima 6421/6441 is newer: production began 14 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 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 drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the 4630 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Proxima 6421/6441 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
