Massey Ferguson 255 Horsepower FAQ
How much PTO horsepower does the Massey Ferguson 255 have?
The listed PTO output is 50 hp, below the 65 hp benchmark average. For real use, size PTO implements below or near 50 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the Massey Ferguson 255 have?
The listed drawbar output is 42 hp, below the 55 hp benchmark average. For pulling work, the safer assumption is about 42 hp at the drawbar before soil, ballast and tire limits are considered.
Is the Massey Ferguson 255 better judged by PTO hp or drawbar hp?
The drawbar output is about 84% of PTO output, comparing 42 drawbar hp with 50 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 255 engine?
The engine displacement is 236 ci, close to the 260 ci benchmark average. It is close to the normal engine-size range for this horsepower class.
Is the Massey Ferguson 255 engine stressed for its PTO horsepower?
The engine has about 4.7 cubic inches per PTO hp, using 236 ci and 50 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Massey Ferguson 255 make?
The output density is about 12.8 PTO hp per liter, using 50 PTO hp and 3.9 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 255 rated at?
The rated speed is 2,000 rpm, close to the 2,200 rpm benchmark average. The 2,000 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.
