International Harvester Farmall 766 or Landini R-8500 (DT) "TL 23 N/A"?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the Farmall 766 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the R-8500 (DT) "TL 23 N/A" has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The International Harvester Farmall 766 suits loader and hydraulic implement work better on this data: 70% (18.8 L/min / 5.0 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 International Harvester Farmall 766 has 70% more hydraulic flow (18.8 L/min / 5.0 gpm) than the Landini R-8500 (DT) "TL 23 N/A" (both pump flow, as stated by the source).
- The International Harvester Farmall 766 is 97% heavier (2,534 kg / 5,587 lb) than the Landini R-8500 (DT) "TL 23 N/A" (both unladen weight, as stated by the source).
- The Landini R-8500 (DT) "TL 23 N/A" is available with four-wheel drive; the International Harvester Farmall 766 is two-wheel drive (as stated by the sources).
- 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, 1000 rpm).
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- Not comparable on power at the PTO shaft: the Farmall 766 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the R-8500 (DT) "TL 23 N/A" 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.
