Massey Ferguson 8680 Horsepower FAQ
How much horsepower does the Massey Ferguson 8680 have?
The listed engine output is 320 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 320 hp.
How much PTO horsepower does the Massey Ferguson 8680 have?
The listed PTO output is 275 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 275 hp.
How much drawbar horsepower does the Massey Ferguson 8680 have?
The listed drawbar output is 240.7 hp, above the 150 hp benchmark average. That makes the 240.7 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the Massey Ferguson 8680?
The PTO-to-engine transfer works out to 85.9%, from 320 engine hp to 275 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Massey Ferguson 8680 for pulling work?
The drawbar-to-engine transfer is about 75.2%, from 320 engine hp to 240.7 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Massey Ferguson 8680 better judged by PTO hp or drawbar hp?
The drawbar output is about 87.5% of PTO output, comparing 240.7 drawbar hp with 275 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 8680 engine?
The engine displacement is 512.6 ci, close to the 520 ci benchmark average. It is close to the normal engine-size range for this horsepower class.
Is the Massey Ferguson 8680 engine stressed for its PTO horsepower?
The engine has about 1.9 cubic inches per PTO hp, using 512.6 ci and 275 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Massey Ferguson 8680 make?
The output density is about 32.7 PTO hp per liter, using 275 PTO hp and 8.4 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 masseyferguson.com website before buying parts, sizing implements or making repair decisions.
