Case IH Farmall DX48 Horsepower FAQ

How much horsepower does the Case IH Farmall DX48 have?

The listed engine output is 48 hp, above the 35 hp benchmark average. That is a higher-power result, so ballast, tire setup and implement width matter if you want to use the full 48 hp.

The listed PTO output is 40 hp, above the 28 hp benchmark average. That is the number to use for mowers, balers, augers, pumps and other PTO tools that need up to about 40 hp.

How much engine power reaches the PTO on the Case IH Farmall DX48?

The PTO-to-engine transfer works out to 83.3%, from 48 engine hp to 40 PTO hp. That is a normal usable range for judging PTO implement fit.

How big is the Case IH Farmall DX48 engine?

The engine displacement is 135.2 ci, above the 110 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.

Is the Case IH Farmall DX48 engine stressed for its PTO horsepower?

The engine has about 3.4 cubic inches per PTO hp, using 135.2 ci and 40 PTO hp. That is close to the normal benchmark for this category.

How much PTO horsepower per liter does the Case IH Farmall DX48 make?

The output density is about 18.2 PTO hp per liter, using 40 PTO hp and 2.2 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
