New Holland T7.170 Horsepower FAQ
How much horsepower does the New Holland T7.170 have?
The listed engine output is 125 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 125 hp.
How much PTO horsepower does the New Holland T7.170 have?
The listed PTO output is 100 hp, below the 175 hp benchmark average. For real use, size PTO implements below or near 100 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the New Holland T7.170 have?
The listed drawbar output is 104.2 hp, below the 150 hp benchmark average. For pulling work, the safer assumption is about 104.2 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the New Holland T7.170?
The PTO-to-engine transfer works out to 80%, from 125 engine hp to 100 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland T7.170 for pulling work?
The drawbar-to-engine transfer is about 83.4%, from 125 engine hp to 104.2 drawbar hp. That is a strong pulling-efficiency number if the specs come from the same test setup.
Is the New Holland T7.170 better judged by PTO hp or drawbar hp?
The drawbar output is about 104.2% of PTO output, comparing 104.2 drawbar hp with 100 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland T7.170 engine?
The engine displacement is 411 ci, below the 520 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the New Holland T7.170 engine stressed for its PTO horsepower?
The engine has about 4.1 cubic inches per PTO hp, using 411 ci and 100 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the New Holland T7.170 make?
The output density is about 14.9 PTO hp per liter, using 100 PTO hp and 6.7 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.
