John Deere 9400T specs: hp, weight, years
John Deere 6.125 HRW-08 six-cylinder diesel. The manufacturer claimed 419.5 horsepower. The only laboratory test on record is of one version: OECD Test 1967 measured 346.5 hp at the PTO of the 9400T (Rubber tracklaying tractor). Compared at the engine's rated speed, where the brochure figure is quoted, the shaft gave 299.7 hp — 28.5% below the claim.
