Case IH 385 Horsepower FAQ
How much horsepower does the Case IH 385 have?
The listed engine output is 43 hp, above the 35 hp benchmark average. That is a higher-power result, so ballast, tire setup and implement width matter if you want to use the full 43 hp.
How much PTO horsepower does the Case IH 385 have?
The listed PTO output is 35 hp, above the 28 hp benchmark average. That is the number to use for mowers, balers, augers, pumps and other PTO tools that need up to about 35 hp.
How much engine power reaches the PTO on the Case IH 385?
The PTO-to-engine transfer works out to 81.4%, from 43 engine hp to 35 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the Case IH 385 engine?
The engine displacement is 155 ci, above the 110 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.
Is the Case IH 385 engine stressed for its PTO horsepower?
The engine has about 4.4 cubic inches per PTO hp, using 155 ci and 35 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Case IH 385 make?
The output density is about 14 PTO hp per liter, using 35 PTO hp and 2.5 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 385 have?
The listed torque is 119 lb-ft, above the 95 lb-ft benchmark average. The 119 lb-ft figure is useful for lugging, loader work and heavy PTO load recovery.
Does the Case IH 385 have good torque for its PTO horsepower?
The torque-to-PTO-power figure is about 3.4 lb-ft per PTO hp, using 119 lb-ft and 35 PTO hp. A higher number usually points to a slower, gruntier working feel.
What rpm is the Case IH 385 rated at?
The rated speed is 2,200 rpm, close to the 2,400 rpm benchmark average. The 2,200 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.
