Case IH DX25 Horsepower FAQ
How much horsepower does the Case IH DX25 have?
The listed engine output is 25 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 25 hp.
How much PTO horsepower does the Case IH DX25 have?
The listed PTO output is 20.3 hp, below the 28 hp benchmark average. For real use, size PTO implements below or near 20.3 hp rather than using a bigger engine-horsepower number.
How much engine power reaches the PTO on the Case IH DX25?
The PTO-to-engine transfer works out to 81.2%, from 25 engine hp to 20.3 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the Case IH DX25 engine?
The engine displacement is 81.2 ci, below the 110 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the Case IH DX25 engine stressed for its PTO horsepower?
The engine has about 4 cubic inches per PTO hp, using 81.2 ci and 20.3 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Case IH DX25 make?
The output density is about 15.6 PTO hp per liter, using 20.3 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 DX25 rated at?
The rated speed is 2,600 rpm, close to the 2,400 rpm benchmark average. The 2,600 rpm figure is around normal for this class.
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.
