New Holland T9.480 Horsepower FAQ
How much horsepower does the New Holland T9.480 have?
The listed engine output is 420 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 420 hp.
How much PTO horsepower does the New Holland T9.480 have?
The listed PTO output is 355 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 355 hp.
How much drawbar horsepower does the New Holland T9.480 have?
The listed drawbar output is 340.9 hp, above the 150 hp benchmark average. That makes the 340.9 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the New Holland T9.480?
The PTO-to-engine transfer works out to 84.5%, from 420 engine hp to 355 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland T9.480 for pulling work?
The drawbar-to-engine transfer is about 81.2%, from 420 engine hp to 340.9 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland T9.480 better judged by PTO hp or drawbar hp?
The drawbar output is about 96% of PTO output, comparing 340.9 drawbar hp with 355 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland T9.480 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 New Holland T9.480 engine stressed for its PTO horsepower?
The engine has about 2.2 cubic inches per PTO hp, using 787 ci and 355 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the New Holland T9.480 make?
The output density is about 27.5 PTO hp per liter, using 355 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.
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 newholland.com website before buying parts, sizing implements or making repair decisions.
