Case IH 9170 Horsepower FAQ
How much horsepower does the Case IH 9170 have?
The listed engine output is 335 hp, above the 210 hp benchmark average. That is a higher-power result, so ballast, tire setup and implement width matter if you want to use the full 335 hp.
How much PTO horsepower does the Case IH 9170 have?
The listed PTO output is 300 hp, above the 175 hp benchmark average. That is the number to use for mowers, balers, augers, pumps and other PTO tools that need up to about 300 hp.
How much engine power reaches the PTO on the Case IH 9170?
The PTO-to-engine transfer works out to 89.6%, from 335 engine hp to 300 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the Case IH 9170 engine?
The engine displacement is 855 ci, above the 520 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.
Is the Case IH 9170 engine stressed for its PTO horsepower?
The engine has about 2.9 cubic inches per PTO hp, using 855 ci and 300 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH 9170 make?
The output density is about 21.4 PTO hp per liter, using 300 PTO hp and 14 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 9170 have?
The listed torque is 1,131 lb-ft, above the 700 lb-ft benchmark average. The 1,131 lb-ft figure is useful for lugging, loader work and heavy PTO load recovery.
Does the Case IH 9170 have good torque for its PTO horsepower?
The torque-to-PTO-power figure is about 3.8 lb-ft per PTO hp, using 1,131 lb-ft and 300 PTO hp. A higher number usually points to a slower, gruntier working feel.
What rpm is the Case IH 9170 rated at?
The rated speed is 2,100 rpm, close to the 2,100 rpm benchmark average. The 2,100 rpm figure is around normal for this class.
