David Brown 880 Implematic or John Deere 620?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 880 Implematic has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 620 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The John Deere 620 suits loader and hydraulic implement work better on this data: 48% (11.0 L/min / 2.9 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 John Deere 620 has 48% more hydraulic flow (11.0 L/min / 2.9 gpm) than the David Brown 880 Implematic (both pump flow, as stated by the source).
- The John Deere 620 is 46% heavier (842 kg / 1,856 lb) than the David Brown 880 Implematic (both unladen weight, as stated by the source).
- The David Brown 880 Implematic is newer: production began 5 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 difference is under the 10% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the 880 Implematic has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the 620 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- 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.
