Case IH Farmall 25SC Horsepower FAQ

How much horsepower does the Case IH Farmall 25SC have?

The listed engine output is 24.7 hp, below the 35 hp benchmark average. That is a lower-power result, so the smarter match is lighter implements and jobs that do not demand more than about 24.7 hp.

How much PTO horsepower does the Case IH Farmall 25SC have?

The listed PTO output is 17.2 hp, below the 28 hp benchmark average. For real use, size PTO implements below or near 17.2 hp rather than using a bigger engine-horsepower number.

How much engine power reaches the PTO on the Case IH Farmall 25SC?

The PTO-to-engine transfer works out to 69.6%, from 24.7 engine hp to 17.2 PTO hp. That is a noticeable drop, so implement sizing should be conservative.

How big is the Case IH Farmall 25SC engine?

The engine displacement is 77.2 ci, below the 110 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.

Is the Case IH Farmall 25SC engine stressed for its PTO horsepower?

The engine has about 4.5 cubic inches per PTO hp, using 77.2 ci and 17.2 PTO hp. That points to a larger-displacement, lower-stress style setup.

How much PTO horsepower per liter does the Case IH Farmall 25SC make?

The output density is about 13.2 PTO hp per liter, using 17.2 PTO hp and 1.3 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.

What rpm is the Case IH Farmall 25SC rated at?

The rated speed is 3,000 rpm, above the 2,400 rpm benchmark average. A higher 3,000 rpm rating can make power well but may feel busier under load.

Official information note

Horsepower and engine specs can vary by year, market, engine option, fuel system, test standard and tractor configuration. Check the operator manual, spec plate, parts book and official caseih.com website before buying parts, sizing implements or making repair decisions.
