David Brown 850 Implematic or International Harvester D-430?
Which should you choose?
On performance, every comparable figure that differs favours the David Brown 850 Implematic: hydraulic flow and three-point lift. It is also ahead on top speed.
- The David Brown 850 Implematic suits loader and hydraulic implement work better on this data: 46% (7.2 L/min / 1.9 gpm) more hydraulic flow and 46% (276 kg / 608 lb) more three-point lift.
- The David Brown 850 Implematic suits road haulage better on this data: 25% (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 “similar machines”. 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 850 Implematic has 46% more hydraulic flow (7.2 L/min / 1.9 gpm) than the International Harvester D-430 (both pump flow, as stated by the source).
- The David Brown 850 Implematic has 46% more lift (276 kg / 608 lb) than the International Harvester D-430 (both lift at the hitch ends, as stated by the source).
- The David Brown 850 Implematic has 25% more top speed (5.0 km/h / 3.1 mph) than the International Harvester D-430 (both top speed forward, as stated by the source).
- 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 weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
