Case IH Magnum 245 Horsepower FAQ
How much horsepower does the Case IH Magnum 245 have?
The listed engine output is 248 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 248 hp.
How much PTO horsepower does the Case IH Magnum 245 have?
The listed PTO output is 200 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 200 hp.
How much drawbar horsepower does the Case IH Magnum 245 have?
The listed drawbar output is 172.7 hp, above the 150 hp benchmark average. That makes the 172.7 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the Case IH Magnum 245?
The PTO-to-engine transfer works out to 80.6%, from 248 engine hp to 200 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH Magnum 245 for pulling work?
The drawbar-to-engine transfer is about 69.6%, from 248 engine hp to 172.7 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Case IH Magnum 245 better judged by PTO hp or drawbar hp?
The drawbar output is about 86.3% of PTO output, comparing 172.7 drawbar hp with 200 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH Magnum 245 engine?
The engine displacement is 504.5 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 Magnum 245 engine stressed for its PTO horsepower?
The engine has about 2.5 cubic inches per PTO hp, using 504.5 ci and 200 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH Magnum 245 make?
The output density is about 24.1 PTO hp per liter, using 200 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.
Official information note
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.
