New Holland T4.105 Horsepower FAQ
How much horsepower does the New Holland T4.105 have?
The listed engine output is 106 hp, above the 80 hp benchmark average. That is a higher-power result, so ballast, tire setup and implement width matter if you want to use the full 106 hp.
How much PTO horsepower does the New Holland T4.105 have?
The listed PTO output is 91 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 91 hp.
How much drawbar horsepower does the New Holland T4.105 have?
The listed drawbar output is 59.8 hp, close to the 55 hp benchmark average. It gives a realistic pulling-power figure of about 59.8 hp.
How much engine power reaches the PTO on the New Holland T4.105?
The PTO-to-engine transfer works out to 85.8%, from 106 engine hp to 91 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland T4.105 for pulling work?
The drawbar-to-engine transfer is about 56.4%, from 106 engine hp to 59.8 drawbar hp. That means traction losses and drivetrain losses are a big part of the real pulling result.
Is the New Holland T4.105 better judged by PTO hp or drawbar hp?
The drawbar output is about 65.7% of PTO output, comparing 59.8 drawbar hp with 91 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland T4.105 engine?
The engine displacement is 207 ci, below the 260 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the New Holland T4.105 engine stressed for its PTO horsepower?
The engine has about 2.3 cubic inches per PTO hp, using 207 ci and 91 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the New Holland T4.105 make?
The output density is about 26.8 PTO hp per liter, using 91 PTO hp and 3.4 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
