New Holland TT60A Horsepower FAQ
How much horsepower does the New Holland TT60A have?
The listed engine output is 56 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 56 hp.
How much PTO horsepower does the New Holland TT60A 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 engine power reaches the PTO on the New Holland TT60A?
The PTO-to-engine transfer works out to 83.9%, from 56 engine hp to 47 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the New Holland TT60A 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 TT60A engine stressed for its PTO horsepower?
The engine has about 3.8 cubic inches per PTO hp, using 179 ci and 47 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the New Holland TT60A make?
The output density is about 16.2 PTO hp per liter, using 47 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.
What rpm is the New Holland TT60A rated at?
The rated speed is 2,500 rpm, above the 2,200 rpm benchmark average. A higher 2,500 rpm rating can make power well but may feel busier under load.
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.
