J.I. Case 1570 or J.I. Case 4490?
Which should you choose?
On performance, every comparable figure that differs favours the J.I. Case 4490: hydraulic flow and three-point lift. It is also ahead on drive.
- The J.I. Case 4490 suits loader and hydraulic implement work better on this data: 20% (15.1 L/min / 4.0 gpm) more hydraulic flow and 39% (1,390 kg / 3,064 lb) more three-point lift.
- The J.I. Case 4490 suits heavy draft work (ploughing, cultivating) better on this data: 28% (2,064 kg / 4,550 lb) heavier and four-wheel drive.
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 J.I. Case 4490 has 20% more hydraulic flow (15.1 L/min / 4.0 gpm) than the J.I. Case 1570 (both pump flow, as stated by the source).
- The J.I. Case 4490 has 39% more lift (1,390 kg / 3,064 lb) than the J.I. Case 1570 (both lift at the hitch ends, as stated by the source).
- The J.I. Case 4490 is 28% heavier (2,064 kg / 4,550 lb) than the J.I. Case 1570 (both unladen weight, as stated by the source).
- The J.I. Case 4490 is available with four-wheel drive; the J.I. Case 1570 is two-wheel drive (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 forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- 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 (1000 rpm).
- Even on PTO independence: every PTO is independent.
- 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 and a creeper range.
