Case IH 4494 Horsepower FAQ
How much horsepower does the Case IH 4494 have?
The listed engine output is 213 hp, close to the 210 hp benchmark average. That puts the tractor in a normal working range for this benchmark group, with 213 hp as the main engine number.
How much PTO horsepower does the Case IH 4494 have?
The listed PTO output is 175 hp, close to the 175 hp benchmark average. Use 175 PTO hp as the practical implement-sizing number.
How much drawbar horsepower does the Case IH 4494 have?
The listed drawbar output is 150.1 hp, close to the 150 hp benchmark average. It gives a realistic pulling-power figure of about 150.1 hp.
How much engine power reaches the PTO on the Case IH 4494?
The PTO-to-engine transfer works out to 82.2%, from 213 engine hp to 175 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH 4494 for pulling work?
The drawbar-to-engine transfer is about 70.5%, from 213 engine hp to 150.1 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Case IH 4494 better judged by PTO hp or drawbar hp?
The drawbar output is about 85.8% of PTO output, comparing 150.1 drawbar hp with 175 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH 4494 engine?
The engine displacement is 504 ci, close to the 520 ci benchmark average. It is close to the normal engine-size range for this horsepower class.
Is the Case IH 4494 engine stressed for its PTO horsepower?
The engine has about 2.9 cubic inches per PTO hp, using 504 ci and 175 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH 4494 make?
The output density is about 21.1 PTO hp per liter, using 175 PTO hp and 8.3 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.
