Massey Ferguson 243 Horsepower FAQ
How much horsepower does the Massey Ferguson 243 have?
The listed engine output is 52 hp, below the 80 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 52 hp.
How much PTO horsepower does the Massey Ferguson 243 have?
The listed PTO output is 47 hp, below the 65 hp benchmark average. For real use, size PTO implements below or near 47 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the Massey Ferguson 243 have?
The listed drawbar output is 37.7 hp, below the 55 hp benchmark average. For pulling work, the safer assumption is about 37.7 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the Massey Ferguson 243?
The PTO-to-engine transfer works out to 90.4%, from 52 engine hp to 47 PTO hp. That is a strong transfer figure when the two specs are from the same configuration.
How efficient is the Massey Ferguson 243 for pulling work?
The drawbar-to-engine transfer is about 72.5%, from 52 engine hp to 37.7 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Massey Ferguson 243 better judged by PTO hp or drawbar hp?
The drawbar output is about 80.2% of PTO output, comparing 37.7 drawbar hp with 47 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Massey Ferguson 243 engine?
The engine displacement is 165 ci, below the 260 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the Massey Ferguson 243 engine stressed for its PTO horsepower?
The engine has about 3.5 cubic inches per PTO hp, using 165 ci and 47 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the Massey Ferguson 243 make?
The output density is about 17.4 PTO hp per liter, using 47 PTO hp and 2.7 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.
