Massey Ferguson 4255 Horsepower FAQ
How much horsepower does the Massey Ferguson 4255 have?
The listed engine output is 95 hp, above the 80 hp benchmark average. That is a higher-power result, so ballast, tire setup and implement width matter if you want to use the full 95 hp.
How much PTO horsepower does the Massey Ferguson 4255 have?
The listed PTO output is 86.8 hp, above the 65 hp benchmark average. That is the number to use for mowers, balers, augers, pumps and other PTO tools that need up to about 86.8 hp.
How much engine power reaches the PTO on the Massey Ferguson 4255?
The PTO-to-engine transfer works out to 91.4%, from 95 engine hp to 86.8 PTO hp. That is a strong transfer figure when the two specs are from the same configuration.
How big is the Massey Ferguson 4255 engine?
The engine displacement is 244 ci, close to the 260 ci benchmark average. It is close to the normal engine-size range for this horsepower class.
Is the Massey Ferguson 4255 engine stressed for its PTO horsepower?
The engine has about 2.8 cubic inches per PTO hp, using 244 ci and 86.8 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Massey Ferguson 4255 make?
The output density is about 21.7 PTO hp per liter, using 86.8 PTO hp and 4 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
