David Brown 995 or IMT 577 (DV)?
Which should you choose?
On performance, every comparable figure that differs favours the David Brown 995: hydraulic flow. On features, the IMT 577 (DV) is ahead on top speed and drive.
- The David Brown 995 suits loader and hydraulic implement work better on this data: 26% (5.9 L/min / 1.6 gpm) more hydraulic flow.
- The IMT 577 (DV) suits heavy draft work (ploughing, cultivating) better on this data: 13% (330 kg / 728 lb) heavier and four-wheel drive.
- The IMT 577 (DV) 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 David Brown 995 has 26% more hydraulic flow (5.9 L/min / 1.6 gpm) than the IMT 577 (DV) (both pump flow, as stated by the source).
- The IMT 577 (DV) is 13% heavier (330 kg / 728 lb) than the David Brown 995 (both unladen weight, as stated by the source).
- The IMT 577 (DV) has 20% more top speed (5.0 km/h / 3.1 mph) than the David Brown 995 (both top speed forward, as stated by the source).
- The IMT 577 (DV) is available with four-wheel drive; the David Brown 995 is two-wheel drive (as stated by the sources).
- The IMT 577 (DV) is newer: production began 10 years later. We hold no parts-availability data, so there is no call on parts.
- 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 difference is under the 25% threshold, too small to call.
- 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, three-point lift, maximum permissible mass, a creeper range and PTO independence.
