Case IH Steiger 550 Quadtrac Horsepower FAQ
How much horsepower does the Case IH Steiger 550 Quadtrac have?
The listed engine output is 550 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 550 hp.
How much PTO horsepower does the Case IH Steiger 550 Quadtrac have?
The listed PTO output is 475 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 475 hp.
How much drawbar horsepower does the Case IH Steiger 550 Quadtrac have?
The listed drawbar output is 434.2 hp, above the 150 hp benchmark average. That makes the 434.2 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the Case IH Steiger 550 Quadtrac?
The PTO-to-engine transfer works out to 86.4%, from 550 engine hp to 475 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH Steiger 550 Quadtrac for pulling work?
The drawbar-to-engine transfer is about 78.9%, from 550 engine hp to 434.2 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Case IH Steiger 550 Quadtrac better judged by PTO hp or drawbar hp?
The drawbar output is about 91.4% of PTO output, comparing 434.2 drawbar hp with 475 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH Steiger 550 Quadtrac engine?
The engine displacement is 787 ci, above the 520 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.
Is the Case IH Steiger 550 Quadtrac engine stressed for its PTO horsepower?
The engine has about 1.7 cubic inches per PTO hp, using 787 ci and 475 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH Steiger 550 Quadtrac make?
The output density is about 36.8 PTO hp per liter, using 475 PTO hp and 12.9 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.
