Massey Ferguson MF 575 (A) or Nuffield 4/65 (465)?
Which should you choose?
On performance, every comparable figure that differs favours the Massey Ferguson MF 575 (A): hydraulic flow and three-point lift. It is also ahead on drive. On features, the Nuffield 4/65 (465) is ahead on top speed.
- The Massey Ferguson MF 575 (A) suits loader and hydraulic implement work better on this data: 108% (32.5 L/min / 8.6 gpm) more hydraulic flow and 24% (400 kg / 882 lb) more three-point lift.
- The Massey Ferguson MF 575 (A) suits heavy draft work (ploughing, cultivating) better on this data: 22% (574 kg / 1,265 lb) heavier and four-wheel drive.
- The Nuffield 4/65 (465) 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.

- Even on power at the PTO shaft (both power at the PTO, claimed): the difference is under the 10% threshold for claimed figures, 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).
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range and PTO independence.
