New Holland T4.120 Horsepower FAQ
How much horsepower does the New Holland T4.120 have?
The listed engine output is 117 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 117 hp.
How much PTO horsepower does the New Holland T4.120 have?
The listed PTO output is 99 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 99 hp.
How much drawbar horsepower does the New Holland T4.120 have?
The listed drawbar output is 76 hp, above the 55 hp benchmark average. That makes the 76 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the New Holland T4.120?
The PTO-to-engine transfer works out to 84.6%, from 117 engine hp to 99 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland T4.120 for pulling work?
The drawbar-to-engine transfer is about 65%, from 117 engine hp to 76 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland T4.120 better judged by PTO hp or drawbar hp?
The drawbar output is about 76.8% of PTO output, comparing 76 drawbar hp with 99 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland T4.120 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 T4.120 engine stressed for its PTO horsepower?
The engine has about 2.1 cubic inches per PTO hp, using 207 ci and 99 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the New Holland T4.120 make?
The output density is about 29.1 PTO hp per liter, using 99 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.
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.
