Massey Ferguson 825 Horsepower FAQ
How much horsepower does the Massey Ferguson 825 have?
The listed engine output is 25 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 25 hp.
How much PTO horsepower does the Massey Ferguson 825 have?
The listed PTO output is 24.4 hp, below the 28 hp benchmark average. For real use, size PTO implements below or near 24.4 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the Massey Ferguson 825 have?
The listed drawbar output is 20 hp, below the 24 hp benchmark average. For pulling work, the safer assumption is about 20 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the Massey Ferguson 825?
The PTO-to-engine transfer works out to 97.6%, from 25 engine hp to 24.4 PTO hp. That is a strong transfer figure when the two specs are from the same configuration.
How efficient is the Massey Ferguson 825 for pulling work?
The drawbar-to-engine transfer is about 80%, from 25 engine hp to 20 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Massey Ferguson 825 better judged by PTO hp or drawbar hp?
The drawbar output is about 82% of PTO output, comparing 20 drawbar hp with 24.4 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 825 engine?
The engine displacement is 107 ci, close to the 110 ci benchmark average. It is close to the normal engine-size range for this horsepower class.
Is the Massey Ferguson 825 engine stressed for its PTO horsepower?
The engine has about 4.4 cubic inches per PTO hp, using 107 ci and 24.4 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Massey Ferguson 825 make?
The output density is about 13.6 PTO hp per liter, using 24.4 PTO hp and 1.8 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
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.
