Massey Ferguson 7718S Horsepower FAQ
How much horsepower does the Massey Ferguson 7718S have?
The listed engine output is 165 hp, below the 210 hp benchmark average. That is a lower-power result, so the smarter match is lighter implements and jobs that do not demand more than about 165 hp.
How much PTO horsepower does the Massey Ferguson 7718S have?
The listed PTO output is 135 hp, below the 175 hp benchmark average. For real use, size PTO implements below or near 135 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the Massey Ferguson 7718S have?
The listed drawbar output is 126.6 hp, below the 150 hp benchmark average. For pulling work, the safer assumption is about 126.6 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the Massey Ferguson 7718S?
The PTO-to-engine transfer works out to 81.8%, from 165 engine hp to 135 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Massey Ferguson 7718S for pulling work?
The drawbar-to-engine transfer is about 76.7%, from 165 engine hp to 126.6 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Massey Ferguson 7718S better judged by PTO hp or drawbar hp?
The drawbar output is about 93.8% of PTO output, comparing 126.6 drawbar hp with 135 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 7718S engine?
The engine displacement is 402.5 ci, below the 520 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the Massey Ferguson 7718S engine stressed for its PTO horsepower?
The engine has about 3 cubic inches per PTO hp, using 402.5 ci and 135 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the Massey Ferguson 7718S make?
The output density is about 20.4 PTO hp per liter, using 135 PTO hp and 6.6 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.
