New Holland TM115 Horsepower FAQ
How much horsepower does the New Holland TM115 have?
The listed engine output is 115 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 115 hp.
How much PTO horsepower does the New Holland TM115 have?
The listed PTO output is 92 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 92 hp.
How much drawbar horsepower does the New Holland TM115 have?
The listed drawbar output is 76.2 hp, above the 55 hp benchmark average. That makes the 76.2 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the New Holland TM115?
The PTO-to-engine transfer works out to 80%, from 115 engine hp to 92 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland TM115 for pulling work?
The drawbar-to-engine transfer is about 66.3%, from 115 engine hp to 76.2 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland TM115 better judged by PTO hp or drawbar hp?
The drawbar output is about 82.8% of PTO output, comparing 76.2 drawbar hp with 92 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland TM115 engine?
The engine displacement is 456 ci, above the 260 ci benchmark average. Bigger displacement can help low-rpm pull and load-holding feel.
Is the New Holland TM115 engine stressed for its PTO horsepower?
The engine has about 5 cubic inches per PTO hp, using 456 ci and 92 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the New Holland TM115 make?
The output density is about 12.3 PTO hp per liter, using 92 PTO hp and 7.5 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.
