New Holland T9.670 Horsepower FAQ
How much horsepower does the New Holland T9.670 have?
The listed engine output is 608 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 608 hp.
How much PTO horsepower does the New Holland T9.670 have?
The listed PTO output is 530.7 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 530.7 hp.
How much drawbar horsepower does the New Holland T9.670 have?
The listed drawbar output is 490.4 hp, above the 150 hp benchmark average. That makes the 490.4 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the New Holland T9.670?
The PTO-to-engine transfer works out to 87.3%, from 608 engine hp to 530.7 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland T9.670 for pulling work?
The drawbar-to-engine transfer is about 80.7%, from 608 engine hp to 490.4 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland T9.670 better judged by PTO hp or drawbar hp?
The drawbar output is about 92.4% of PTO output, comparing 490.4 drawbar hp with 530.7 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland T9.670 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 T9.670 engine stressed for its PTO horsepower?
The engine has about 1.5 cubic inches per PTO hp, using 787 ci and 530.7 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the New Holland T9.670 make?
The output density is about 41.1 PTO hp per liter, using 530.7 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.
