Case IH 235 Horsepower FAQ
How much horsepower does the Case IH 235 have?
The listed engine output is 18 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 18 hp.
How much PTO horsepower does the Case IH 235 have?
The listed PTO output is 15.2 hp, below the 28 hp benchmark average. For real use, size PTO implements below or near 15.2 hp rather than using a bigger engine-horsepower number.
How much engine power reaches the PTO on the Case IH 235?
The PTO-to-engine transfer works out to 84.4%, from 18 engine hp to 15.2 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the Case IH 235 engine?
The engine displacement is 51.8 ci, below the 110 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the Case IH 235 engine stressed for its PTO horsepower?
The engine has about 3.4 cubic inches per PTO hp, using 51.8 ci and 15.2 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the Case IH 235 make?
The output density is about 19 PTO hp per liter, using 15.2 PTO hp and 0.8 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 235 rated at?
The rated speed is 2,700 rpm, above the 2,400 rpm benchmark average. A higher 2,700 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.
