Which
tractor?

Tractor specifications with the measured power at the shaft beside the number on the brochure — because they are not the same quantity. Every figure carries its source.

On record

How much power at the shaft?

The bars count 1226 of the 2,500 tractors on record by horsepower at the PTO shaft: 38 measured by a laboratory, 1188 as claimed. 1274 with only an engine figure are not counted — engine power is a different quantity.

  1. <25 hp at the PTO:95 tractors
  2. 25–40 hp at the PTO:160 tractors
  3. 40–60 hp at the PTO:317 tractors
  4. 60–100 hp at the PTO:340 tractors
  5. 100–175 hp at the PTO:199 tractors
  6. 175–300 hp at the PTO:88 tractors
  7. 300+ hp at the PTO:27 tractors

Measured. Not marketed.

Why believe these numbers?

Because each one says where it came from. Where an independent laboratory has tested a tractor, its page leads with the power measured at the PTO shaft and names the test report — 177 reports on file for 38 of the 2,500 tractors on record. Where no test exists, the figure is labelled as the manufacturer’s claim, never as measured.
