David Brown 990 Selectmatic or IMR-RAKOVICA R-60?
Which should you choose?
On performance, every comparable figure that differs favours the IMR-RAKOVICA R-60: hydraulic flow. It is also ahead on top speed.
- The IMR-RAKOVICA R-60 suits loader and hydraulic implement work better on this data: 31% (8.6 L/min / 2.3 gpm) more hydraulic flow.
- The IMR-RAKOVICA R-60 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 “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 IMR-RAKOVICA R-60 has 31% more hydraulic flow (8.6 L/min / 2.3 gpm) than the David Brown 990 Selectmatic (both pump flow, as stated by the source).
- The David Brown 990 Selectmatic is 19% heavier (410 kg / 904 lb) than the IMR-RAKOVICA R-60 (both unladen weight, as stated by the source).
- The IMR-RAKOVICA R-60 has 20% more top speed (5.0 km/h / 3.1 mph) than the David Brown 990 Selectmatic (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 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).
- 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.
