Case IH 4994 Horsepower FAQ
How much horsepower does the Case IH 4994 have?
The listed engine output is 400 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 400 hp.
How much PTO horsepower does the Case IH 4994 have?
The listed PTO output is 344 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 344 hp.
How much drawbar horsepower does the Case IH 4994 have?
The listed drawbar output is 294.2 hp, above the 150 hp benchmark average. That makes the 294.2 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the Case IH 4994?
The PTO-to-engine transfer works out to 86%, from 400 engine hp to 344 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH 4994 for pulling work?
The drawbar-to-engine transfer is about 73.6%, from 400 engine hp to 294.2 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Case IH 4994 better judged by PTO hp or drawbar hp?
The drawbar output is about 85.5% of PTO output, comparing 294.2 drawbar hp with 344 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH 4994 engine?
The engine displacement is 866 ci, above the 520 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.
Is the Case IH 4994 engine stressed for its PTO horsepower?
The engine has about 2.5 cubic inches per PTO hp, using 866 ci and 344 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH 4994 make?
The output density is about 24.2 PTO hp per liter, using 344 PTO hp and 14.2 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.
