Massey Ferguson 8S.305 Horsepower FAQ
How much horsepower does the Massey Ferguson 8S.305 have?
The listed engine output is 301.7 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 301.7 hp.
How much PTO horsepower does the Massey Ferguson 8S.305 have?
The listed PTO output is 265.5 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 265.5 hp.
How much engine power reaches the PTO on the Massey Ferguson 8S.305?
The PTO-to-engine transfer works out to 88%, from 301.7 engine hp to 265.5 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the Massey Ferguson 8S.305 engine?
The engine displacement is 449.4 ci, below the 520 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the Massey Ferguson 8S.305 engine stressed for its PTO horsepower?
The engine has about 1.7 cubic inches per PTO hp, using 449.4 ci and 265.5 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Massey Ferguson 8S.305 make?
The output density is about 35.9 PTO hp per liter, using 265.5 PTO hp and 7.4 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
How much torque does the Massey Ferguson 8S.305 have?
The listed torque is 944.1 lb-ft, above the 700 lb-ft benchmark average. The 944.1 lb-ft figure is useful for lugging, loader work and heavy PTO load recovery.
Does the Massey Ferguson 8S.305 have good torque for its PTO horsepower?
The torque-to-PTO-power figure is about 3.6 lb-ft per PTO hp, using 944.1 lb-ft and 265.5 PTO hp. A higher number usually points to a slower, gruntier working feel.
