International Harvester D-436 or J.I. Case 311-B?
Which should you choose?
On performance, every comparable figure that differs favours the International Harvester D-436: hydraulic flow. It is also ahead on PTO independence. On features, the J.I. Case 311-B is ahead on top speed.
- The International Harvester D-436 suits PTO-driven implements (mowers, balers, pumps) better on this data: an independent PTO.
- The International Harvester D-436 suits loader and hydraulic implement work better on this data: 111% (12.6 L/min / 3.3 gpm) more hydraulic flow.
- The J.I. Case 311-B suits road haulage better on this data: 25% (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 “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 D-436 has 111% more hydraulic flow (12.6 L/min / 3.3 gpm) than the J.I. Case 311-B (both pump flow, as stated by the source).
- The J.I. Case 311-B has 25% more top speed (5.0 km/h / 3.1 mph) than the International Harvester D-436 (both top speed forward, as stated by the source).
- The International Harvester D-436 has an independent PTO; the J.I. Case 311-B’s is dependent (stops with the clutch).
- 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 weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, 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 and a creeper range.
