New Holland TN60A Horsepower FAQ
How much horsepower does the New Holland TN60A have?
The listed engine output is 57 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 57 hp.
How much PTO horsepower does the New Holland TN60A have?
The listed PTO output is 45 hp, below the 65 hp benchmark average. For real use, size PTO implements below or near 45 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the New Holland TN60A have?
The listed drawbar output is 38.4 hp, below the 55 hp benchmark average. For pulling work, the safer assumption is about 38.4 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the New Holland TN60A?
The PTO-to-engine transfer works out to 78.9%, from 57 engine hp to 45 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland TN60A for pulling work?
The drawbar-to-engine transfer is about 67.4%, from 57 engine hp to 38.4 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland TN60A better judged by PTO hp or drawbar hp?
The drawbar output is about 85.3% of PTO output, comparing 38.4 drawbar hp with 45 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland TN60A engine?
The engine displacement is 179 ci, below the 260 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the New Holland TN60A engine stressed for its PTO horsepower?
The engine has about 4 cubic inches per PTO hp, using 179 ci and 45 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the New Holland TN60A make?
The output density is about 15.5 PTO hp per liter, using 45 PTO hp and 2.9 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 newholland.com website before buying parts, sizing implements or making repair decisions.
