Massey Ferguson 7485 Horsepower FAQ

How much horsepower does the Massey Ferguson 7485 have?

The listed engine output is 153 hp, below the 210 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 153 hp.

How much PTO horsepower does the Massey Ferguson 7485 have?

The listed PTO output is 130 hp, below the 175 hp benchmark average. For real use, size PTO implements below or near 130 hp rather than using a bigger engine-horsepower number.

How much drawbar horsepower does the Massey Ferguson 7485 have?

The listed drawbar output is 100.8 hp, below the 150 hp benchmark average. For pulling work, the safer assumption is about 100.8 hp at the drawbar before soil, ballast and tire limits are considered.

How much engine power reaches the PTO on the Massey Ferguson 7485?

The PTO-to-engine transfer works out to 85%, from 153 engine hp to 130 PTO hp. That is a normal usable range for judging PTO implement fit.

How efficient is the Massey Ferguson 7485 for pulling work?

The drawbar-to-engine transfer is about 65.9%, from 153 engine hp to 100.8 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.

Is the Massey Ferguson 7485 better judged by PTO hp or drawbar hp?

The drawbar output is about 77.5% of PTO output, comparing 100.8 drawbar hp with 130 PTO hp. That helps separate pulling ability from PTO implement ability.

How big is the Massey Ferguson 7485 engine?

The engine displacement is 402.5 ci, below the 520 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.

Is the Massey Ferguson 7485 engine stressed for its PTO horsepower?

The engine has about 3.1 cubic inches per PTO hp, using 402.5 ci and 130 PTO hp. That is close to the normal benchmark for this category.

How much PTO horsepower per liter does the Massey Ferguson 7485 make?

The output density is about 19.7 PTO hp per liter, using 130 PTO hp and 6.6 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.

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.
