Massey Ferguson 50 Horsepower FAQ
How much PTO horsepower does the Massey Ferguson 50 have?
The listed PTO output is 38 hp, above the 28 hp benchmark average. That is the number to use for mowers, balers, augers, pumps and other PTO tools that need up to about 38 hp.
How much drawbar horsepower does the Massey Ferguson 50 have?
The listed drawbar output is 34 hp, above the 24 hp benchmark average. That makes the 34 hp drawbar number more useful than engine hp for tillage and heavy pulling.
Is the Massey Ferguson 50 better judged by PTO hp or drawbar hp?
The drawbar output is about 89.5% of PTO output, comparing 34 drawbar hp with 38 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 50 engine?
The engine displacement is 152.7 ci, above the 110 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.
Is the Massey Ferguson 50 engine stressed for its PTO horsepower?
The engine has about 4 cubic inches per PTO hp, using 152.7 ci and 38 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Massey Ferguson 50 make?
The output density is about 15.2 PTO hp per liter, using 38 PTO hp and 2.5 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 50 rated at?
The rated speed is 2,000 rpm, below the 2,400 rpm benchmark average. A lower 2,000 rpm rating can feel more relaxed, but torque and gearing decide the real work feel.
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.
