Massey Ferguson 1531 Horsepower FAQ
How much horsepower does the Massey Ferguson 1531 have?
The listed engine output is 33 hp, close to the 35 hp benchmark average. That puts the tractor in a normal working range for this benchmark group, with 33 hp as the main engine number.
How much PTO horsepower does the Massey Ferguson 1531 have?
The listed PTO output is 24.5 hp, below the 28 hp benchmark average. For real use, size PTO implements below or near 24.5 hp rather than using a bigger engine-horsepower number.
How much engine power reaches the PTO on the Massey Ferguson 1531?
The PTO-to-engine transfer works out to 74.2%, from 33 engine hp to 24.5 PTO hp. That is a noticeable drop, so implement sizing should be conservative.
How big is the Massey Ferguson 1531 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 1531 engine stressed for its PTO horsepower?
The engine has about 3.7 cubic inches per PTO hp, using 91.4 ci and 24.5 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Massey Ferguson 1531 make?
The output density is about 16.3 PTO hp per liter, using 24.5 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 1531 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.
