New Holland TL80 Horsepower FAQ
How much horsepower does the New Holland TL80 have?
The listed engine output is 80 hp, close to the 80 hp benchmark average. That puts the tractor in a normal working range for this benchmark group, with 80 hp as the main engine number.
How much PTO horsepower does the New Holland TL80 have?
The listed PTO output is 66 hp, close to the 65 hp benchmark average. Use 66 PTO hp as the practical implement-sizing number.
How much drawbar horsepower does the New Holland TL80 have?
The listed drawbar output is 42.5 hp, below the 55 hp benchmark average. For pulling work, the safer assumption is about 42.5 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the New Holland TL80?
The PTO-to-engine transfer works out to 82.5%, from 80 engine hp to 66 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland TL80 for pulling work?
The drawbar-to-engine transfer is about 53.1%, from 80 engine hp to 42.5 drawbar hp. That means traction losses and drivetrain losses are a big part of the real pulling result.
Is the New Holland TL80 better judged by PTO hp or drawbar hp?
The drawbar output is about 64.4% of PTO output, comparing 42.5 drawbar hp with 66 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland TL80 engine?
The engine displacement is 238 ci, close to the 260 ci benchmark average. It is close to the normal engine-size range for this horsepower class.
Is the New Holland TL80 engine stressed for its PTO horsepower?
The engine has about 3.6 cubic inches per PTO hp, using 238 ci and 66 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the New Holland TL80 make?
The output density is about 16.9 PTO hp per liter, using 66 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.
