Case IH 8940 Horsepower FAQ
How much PTO horsepower does the Case IH 8940 have?
The listed PTO output is 205 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 205 hp.
How much drawbar horsepower does the Case IH 8940 have?
The listed drawbar output is 176.3 hp, above the 150 hp benchmark average. That makes the 176.3 hp drawbar number more useful than engine hp for tillage and heavy pulling.
Is the Case IH 8940 better judged by PTO hp or drawbar hp?
The drawbar output is about 86% of PTO output, comparing 176.3 drawbar hp with 205 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH 8940 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 8940 engine stressed for its PTO horsepower?
The engine has about 2.5 cubic inches per PTO hp, using 504.5 ci and 205 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH 8940 make?
The output density is about 24.7 PTO hp per liter, using 205 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.
What rpm is the Case IH 8940 rated at?
The rated speed is 2,200 rpm, close to the 2,100 rpm benchmark average. The 2,200 rpm figure is around normal for this class.
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.
