Case IH Farmall 120M Horsepower FAQ
How much horsepower does the Case IH Farmall 120M have?
The listed engine output is 120 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 120 hp.
How much PTO horsepower does the Case IH Farmall 120M have?
The listed PTO output is 100 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 100 hp.
How much engine power reaches the PTO on the Case IH Farmall 120M?
The PTO-to-engine transfer works out to 83.3%, from 120 engine hp to 100 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the Case IH Farmall 120M 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 120M engine stressed for its PTO horsepower?
The engine has about 2.1 cubic inches per PTO hp, using 207 ci and 100 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH Farmall 120M make?
The output density is about 29.4 PTO hp per liter, using 100 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.
