Case IH CS 120 Horsepower FAQ
How much horsepower does the Case IH CS 120 have?
The listed engine output is 113.4 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 113.4 hp.
How much PTO horsepower does the Case IH CS 120 have?
The listed PTO output is 101.6 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 101.6 hp.
How much engine power reaches the PTO on the Case IH CS 120?
The PTO-to-engine transfer works out to 89.6%, from 113.4 engine hp to 101.6 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the Case IH CS 120 engine?
The engine displacement is 402.8 ci, above the 260 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.
Is the Case IH CS 120 engine stressed for its PTO horsepower?
The engine has about 4 cubic inches per PTO hp, using 402.8 ci and 101.6 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Case IH CS 120 make?
The output density is about 15.4 PTO hp per liter, using 101.6 PTO hp and 6.6 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
How much torque does the Case IH CS 120 have?
The listed torque is 342.2 lb-ft, above the 240 lb-ft benchmark average. The 342.2 lb-ft figure is useful for lugging, loader work and heavy PTO load recovery.
Does the Case IH CS 120 have good torque for its PTO horsepower?
The torque-to-PTO-power figure is about 3.4 lb-ft per PTO hp, using 342.2 lb-ft and 101.6 PTO hp. A higher number usually points to a slower, gruntier working feel.
What rpm is the Case IH CS 120 rated at?
The rated speed is 2,300 rpm, close to the 2,200 rpm benchmark average. The 2,300 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.
