John Deere 8400T Extra Horsepower Notes
Horsepower note
The John Deere 8400T is rated at 255.2 hp engine horsepower and 202.3 hp drawbar horsepower, putting usable pulling power about 52.9 hp below engine output.
PTO note
With 300 hp at the PTO, the John Deere 8400T is best matched to large PTO-driven equipment where the implement horsepower requirement matters more than the engine rating; large implements still need to be matched by PTO requirement, ballast, traction and transmission setup.
Drawbar note
For plows, ground tools and pull-type loads, the John Deere 8400T’s 202.3 hp drawbar horsepower says more than engine horsepower alone.
Power-to-weight note
At 18,709 lb and 255.2 hp, the John Deere 8400T works out to about 73.3 lb per engine horsepower, making it light for its power, so traction and ballast can become the limiting factor before engine power.
Engine note
For engine identification, the John Deere 8400T is listed with engine model turbocharged intercooled 6-cylinder, 8.1 L displacement, 6 cylinders.
Official information note
