Massey Ferguson 8730S Horsepower FAQ
How much horsepower does the Massey Ferguson 8730S have?
The listed engine output is 295 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 295 hp.
How much PTO horsepower does the Massey Ferguson 8730S have?
The listed PTO output is 250 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 250 hp.
How much drawbar horsepower does the Massey Ferguson 8730S have?
The listed drawbar output is 217.2 hp, above the 150 hp benchmark average. That makes the 217.2 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the Massey Ferguson 8730S?
The PTO-to-engine transfer works out to 84.7%, from 295 engine hp to 250 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Massey Ferguson 8730S for pulling work?
The drawbar-to-engine transfer is about 73.6%, from 295 engine hp to 217.2 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Massey Ferguson 8730S better judged by PTO hp or drawbar hp?
The drawbar output is about 86.9% of PTO output, comparing 217.2 drawbar hp with 250 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 8730S 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 8730S engine stressed for its PTO horsepower?
The engine has about 2 cubic inches per PTO hp, using 512.6 ci and 250 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Massey Ferguson 8730S make?
The output density is about 29.8 PTO hp per liter, using 250 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.
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.
