Massey Ferguson 1M.25 Horsepower FAQ
How much horsepower does the Massey Ferguson 1M.25 have?
The listed engine output is 24.8 hp, below the 35 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 24.8 hp.
How much PTO horsepower does the Massey Ferguson 1M.25 have?
The listed PTO output is 20.1 hp, below the 28 hp benchmark average. For real use, size PTO implements below or near 20.1 hp rather than using a bigger engine-horsepower number.
How much engine power reaches the PTO on the Massey Ferguson 1M.25?
The PTO-to-engine transfer works out to 81%, from 24.8 engine hp to 20.1 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the Massey Ferguson 1M.25 engine?
The engine displacement is 91.4 ci, below the 110 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the Massey Ferguson 1M.25 engine stressed for its PTO horsepower?
The engine has about 4.5 cubic inches per PTO hp, using 91.4 ci and 20.1 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Massey Ferguson 1M.25 make?
The output density is about 13.4 PTO hp per liter, using 20.1 PTO hp and 1.5 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 1M.25 rated at?
The rated speed is 2,600 rpm, close to the 2,400 rpm benchmark average. The 2,600 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.
