Massey Ferguson 398 Horsepower FAQ
How much horsepower does the Massey Ferguson 398 have?
The listed engine output is 89 hp, close to the 80 hp benchmark average. That puts the tractor in a normal working range for this benchmark group, with 89 hp as the main engine number.
How much PTO horsepower does the Massey Ferguson 398 have?
The listed PTO output is 82 hp, above the 65 hp benchmark average. That is the number to use for mowers, balers, augers, pumps and other PTO tools that need up to about 82 hp.
How much drawbar horsepower does the Massey Ferguson 398 have?
The listed drawbar output is 66.8 hp, above the 55 hp benchmark average. That makes the 66.8 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the Massey Ferguson 398?
The PTO-to-engine transfer works out to 92.1%, from 89 engine hp to 82 PTO hp. That is a strong transfer figure when the two specs are from the same configuration.
How efficient is the Massey Ferguson 398 for pulling work?
The drawbar-to-engine transfer is about 75.1%, from 89 engine hp to 66.8 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Massey Ferguson 398 better judged by PTO hp or drawbar hp?
The drawbar output is about 81.5% of PTO output, comparing 66.8 drawbar hp with 82 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 398 engine?
The engine displacement is 236 ci, close to the 260 ci benchmark average. It is close to the normal engine-size range for this horsepower class.
Is the Massey Ferguson 398 engine stressed for its PTO horsepower?
The engine has about 2.9 cubic inches per PTO hp, using 236 ci and 82 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Massey Ferguson 398 make?
The output density is about 21 PTO hp per liter, using 82 PTO hp and 3.9 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.
