Massey Ferguson 6718S Horsepower FAQ
How much horsepower does the Massey Ferguson 6718S have?
The listed engine output is 167 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 167 hp.
How much PTO horsepower does the Massey Ferguson 6718S have?
The listed PTO output is 155 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 155 hp.
How much engine power reaches the PTO on the Massey Ferguson 6718S?
The PTO-to-engine transfer works out to 92.8%, from 167 engine hp to 155 PTO hp. That is a strong transfer figure when the two specs are from the same configuration.
How big is the Massey Ferguson 6718S engine?
The engine displacement is 299 ci, above the 260 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.
Is the Massey Ferguson 6718S engine stressed for its PTO horsepower?
The engine has about 1.9 cubic inches per PTO hp, using 299 ci and 155 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Massey Ferguson 6718S make?
The output density is about 31.6 PTO hp per liter, using 155 PTO hp and 4.9 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 6718S have?
The listed torque is 620 lb-ft, above the 240 lb-ft benchmark average. The 620 lb-ft figure is useful for lugging, loader work and heavy PTO load recovery.
Does the Massey Ferguson 6718S have good torque for its PTO horsepower?
The torque-to-PTO-power figure is about 4 lb-ft per PTO hp, using 620 lb-ft and 155 PTO hp. A higher number usually points to a slower, gruntier working feel.
What rpm is the Massey Ferguson 6718S rated at?
The rated speed is 2,100 rpm, close to the 2,200 rpm benchmark average. The 2,100 rpm figure is around normal for this class.
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.
