Massey Ferguson 8240 Horsepower FAQ
How much PTO horsepower does the Massey Ferguson 8240 have?
The listed PTO output is 145 hp, below the 175 hp benchmark average. For real use, size PTO implements below or near 145 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the Massey Ferguson 8240 have?
The listed drawbar output is 141.1 hp, close to the 150 hp benchmark average. It gives a realistic pulling-power figure of about 141.1 hp.
Is the Massey Ferguson 8240 better judged by PTO hp or drawbar hp?
The drawbar output is about 97.3% of PTO output, comparing 141.1 drawbar hp with 145 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 8240 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 8240 engine stressed for its PTO horsepower?
The engine has about 2.8 cubic inches per PTO hp, using 402.5 ci and 145 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Massey Ferguson 8240 make?
The output density is about 22 PTO hp per liter, using 145 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.
What rpm is the Massey Ferguson 8240 rated at?
The rated speed is 2,200 rpm, close to the 2,100 rpm benchmark average. The 2,200 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.
