Case IH Farmall 115C Horsepower FAQ
How much horsepower does the Case IH Farmall 115C have?
The listed engine output is 115 hp, above the 80 hp benchmark average. That is a higher-power result, so ballast, tire setup and implement width matter if you want to use the full 115 hp.
How much PTO horsepower does the Case IH Farmall 115C have?
The listed PTO output is 98 hp, above the 65 hp benchmark average. That is the number to use for mowers, balers, augers, pumps and other PTO tools that need up to about 98 hp.
How much drawbar horsepower does the Case IH Farmall 115C have?
The listed drawbar output is 69.3 hp, above the 55 hp benchmark average. That makes the 69.3 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the Case IH Farmall 115C?
The PTO-to-engine transfer works out to 85.2%, from 115 engine hp to 98 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH Farmall 115C for pulling work?
The drawbar-to-engine transfer is about 60.3%, from 115 engine hp to 69.3 drawbar hp. That means traction losses and drivetrain losses are a big part of the real pulling result.
Is the Case IH Farmall 115C better judged by PTO hp or drawbar hp?
The drawbar output is about 70.7% of PTO output, comparing 69.3 drawbar hp with 98 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH Farmall 115C engine?
The engine displacement is 207 ci, below the 260 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the Case IH Farmall 115C engine stressed for its PTO horsepower?
The engine has about 2.1 cubic inches per PTO hp, using 207 ci and 98 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH Farmall 115C make?
The output density is about 28.8 PTO hp per liter, using 98 PTO hp and 3.4 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
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.
