New Holland 9684 Horsepower FAQ
How much horsepower does the New Holland 9684 have?
The listed engine output is 360 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 360 hp.
How much PTO horsepower does the New Holland 9684 have?
The listed PTO output is 349.1 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 349.1 hp.
How much drawbar horsepower does the New Holland 9684 have?
The listed drawbar output is 277.2 hp, above the 150 hp benchmark average. That makes the 277.2 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the New Holland 9684?
The PTO-to-engine transfer works out to 97%, from 360 engine hp to 349.1 PTO hp. That is a strong transfer figure when the two specs are from the same configuration.
How efficient is the New Holland 9684 for pulling work?
The drawbar-to-engine transfer is about 77%, from 360 engine hp to 277.2 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland 9684 better judged by PTO hp or drawbar hp?
The drawbar output is about 79.4% of PTO output, comparing 277.2 drawbar hp with 349.1 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland 9684 engine?
The engine displacement is 855 ci, above the 520 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.
Is the New Holland 9684 engine stressed for its PTO horsepower?
The engine has about 2.5 cubic inches per PTO hp, using 855 ci and 349.1 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the New Holland 9684 make?
The output density is about 24.9 PTO hp per liter, using 349.1 PTO hp and 14 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 newholland.com website before buying parts, sizing implements or making repair decisions.
