New Holland T4.85 Horsepower FAQ
How much horsepower does the New Holland T4.85 have?
The listed engine output is 84 hp, close to the 80 hp benchmark average. That puts the tractor in a normal working range for this benchmark group, with 84 hp as the main engine number.
How much PTO horsepower does the New Holland T4.85 have?
The listed PTO output is 70 hp, close to the 65 hp benchmark average. Use 70 PTO hp as the practical implement-sizing number.
How much drawbar horsepower does the New Holland T4.85 have?
The listed drawbar output is 58.5 hp, close to the 55 hp benchmark average. It gives a realistic pulling-power figure of about 58.5 hp.
How much engine power reaches the PTO on the New Holland T4.85?
The PTO-to-engine transfer works out to 83.3%, from 84 engine hp to 70 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland T4.85 for pulling work?
The drawbar-to-engine transfer is about 69.6%, from 84 engine hp to 58.5 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland T4.85 better judged by PTO hp or drawbar hp?
The drawbar output is about 83.6% of PTO output, comparing 58.5 drawbar hp with 70 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland T4.85 engine?
The engine displacement is 207 ci, below the 260 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the New Holland T4.85 engine stressed for its PTO horsepower?
The engine has about 3 cubic inches per PTO hp, using 207 ci and 70 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the New Holland T4.85 make?
The output density is about 20.6 PTO hp per liter, using 70 PTO hp and 3.4 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.
