New Holland TM175 Horsepower FAQ
How much horsepower does the New Holland TM175 have?
The listed engine output is 175 hp, below the 210 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 175 hp.
How much PTO horsepower does the New Holland TM175 have?
The listed PTO output is 145 hp, below the 175 hp benchmark average. For real use, size PTO implements below or near 145 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the New Holland TM175 have?
The listed drawbar output is 123.6 hp, below the 150 hp benchmark average. For pulling work, the safer assumption is about 123.6 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the New Holland TM175?
The PTO-to-engine transfer works out to 82.9%, from 175 engine hp to 145 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland TM175 for pulling work?
The drawbar-to-engine transfer is about 70.6%, from 175 engine hp to 123.6 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland TM175 better judged by PTO hp or drawbar hp?
The drawbar output is about 85.2% of PTO output, comparing 123.6 drawbar hp with 145 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland TM175 engine?
The engine displacement is 456 ci, below the 520 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the New Holland TM175 engine stressed for its PTO horsepower?
The engine has about 3.1 cubic inches per PTO hp, using 456 ci and 145 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the New Holland TM175 make?
The output density is about 19.3 PTO hp per liter, using 145 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.
