David Brown 950 (Implematic) or J.I. Case 411-B?
Which should you choose?
On performance, every comparable figure that differs favours the David Brown 950 (Implematic): hydraulic flow. It is also ahead on PTO speeds.
- The David Brown 950 (Implematic) suits PTO-driven implements (mowers, balers, pumps) better on this data: offers 1000 rpm.
- The David Brown 950 (Implematic) suits loader and hydraulic implement work better on this data: 146% (16.6 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 David Brown 950 (Implematic) has 146% more hydraulic flow (16.6 L/min / 4.4 gpm) than the J.I. Case 411-B (both pump flow, as stated by the source).
- The David Brown 950 (Implematic) offers 1000 rpm at the PTO, which the J.I. Case 411-B does not (as stated by the sources).
- 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.
- 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 difference is under the 10% threshold, too small to call.
- Even on drive: all two-wheel drive.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- 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.
