Massey Ferguson 7620 Horsepower FAQ
How much horsepower does the Massey Ferguson 7620 have?
The listed engine output is 180 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 180 hp.
How much PTO horsepower does the Massey Ferguson 7620 have?
The listed PTO output is 150 hp, below the 175 hp benchmark average. For real use, size PTO implements below or near 150 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the Massey Ferguson 7620 have?
The listed drawbar output is 137.2 hp, close to the 150 hp benchmark average. It gives a realistic pulling-power figure of about 137.2 hp.
How much engine power reaches the PTO on the Massey Ferguson 7620?
The PTO-to-engine transfer works out to 83.3%, from 180 engine hp to 150 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Massey Ferguson 7620 for pulling work?
The drawbar-to-engine transfer is about 76.2%, from 180 engine hp to 137.2 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Massey Ferguson 7620 better judged by PTO hp or drawbar hp?
The drawbar output is about 91.5% of PTO output, comparing 137.2 drawbar hp with 150 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 7620 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 7620 engine stressed for its PTO horsepower?
The engine has about 2.7 cubic inches per PTO hp, using 402.5 ci and 150 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Massey Ferguson 7620 make?
The output density is about 22.7 PTO hp per liter, using 150 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.
