New Holland T8.350 Horsepower FAQ
How much horsepower does the New Holland T8.350 have?
The listed engine output is 280 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 280 hp.
How much PTO horsepower does the New Holland T8.350 have?
The listed PTO output is 235 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 235 hp.
How much drawbar horsepower does the New Holland T8.350 have?
The listed drawbar output is 213.1 hp, above the 150 hp benchmark average. That makes the 213.1 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the New Holland T8.350?
The PTO-to-engine transfer works out to 83.9%, from 280 engine hp to 235 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland T8.350 for pulling work?
The drawbar-to-engine transfer is about 76.1%, from 280 engine hp to 213.1 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland T8.350 better judged by PTO hp or drawbar hp?
The drawbar output is about 90.7% of PTO output, comparing 213.1 drawbar hp with 235 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland T8.350 engine?
The engine displacement is 531 ci, close to the 520 ci benchmark average. It is close to the normal engine-size range for this horsepower class.
Is the New Holland T8.350 engine stressed for its PTO horsepower?
The engine has about 2.3 cubic inches per PTO hp, using 531 ci and 235 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the New Holland T8.350 make?
The output density is about 27 PTO hp per liter, using 235 PTO hp and 8.7 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.
