New Holland Workmaster 65 Horsepower FAQ
How much horsepower does the New Holland Workmaster 65 have?
The listed engine output is 65 hp, below the 80 hp benchmark average. That is a lower-power result, so the smarter match is lighter implements and jobs that do not demand more than about 65 hp.
How much PTO horsepower does the New Holland Workmaster 65 have?
The listed PTO output is 57 hp, below the 65 hp benchmark average. For real use, size PTO implements below or near 57 hp rather than using a bigger engine-horsepower number.
How much engine power reaches the PTO on the New Holland Workmaster 65?
The PTO-to-engine transfer works out to 87.7%, from 65 engine hp to 57 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the New Holland Workmaster 65 engine?
The engine displacement is 195 ci, below the 260 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the New Holland Workmaster 65 engine stressed for its PTO horsepower?
The engine has about 3.4 cubic inches per PTO hp, using 195 ci and 57 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the New Holland Workmaster 65 make?
The output density is about 17.8 PTO hp per liter, using 57 PTO hp and 3.2 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
What rpm is the New Holland Workmaster 65 rated at?
The rated speed is 2,500 rpm, above the 2,200 rpm benchmark average. A higher 2,500 rpm rating can make power well but may feel busier under load.
