Fiat 1580 (DT) or International Harvester 1086?
Which should you choose?
On performance, every comparable figure that differs favours the Fiat 1580 (DT): hydraulic flow and three-point lift.
- The Fiat 1580 (DT) suits loader and hydraulic implement work better on this data: 23% (10.4 L/min / 2.7 gpm) more hydraulic flow and 48% (1,599 kg / 3,525 lb) more three-point lift.
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 Fiat 1580 (DT) has 23% more hydraulic flow (10.4 L/min / 2.7 gpm) than the International Harvester 1086 (both pump flow, as stated by the source).
- The Fiat 1580 (DT) has 48% more lift (1,599 kg / 3,525 lb) than the International Harvester 1086 (both lift at the hitch ends, as stated by the source).
- The Fiat 1580 (DT) is 13% heavier (728 kg / 1,605 lb) than the International Harvester 1086 (both unladen weight, 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 top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540, 1000 rpm).
- Even on drive: every machine is available with four-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, maximum permissible mass, a creeper range and PTO independence.
