New Holland TV145 Horsepower FAQ
How much horsepower does the New Holland TV145 have?
The listed engine output is 145 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 145 hp.
How much PTO horsepower does the New Holland TV145 have?
The listed PTO output is 105 hp, below the 175 hp benchmark average. For real use, size PTO implements below or near 105 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the New Holland TV145 have?
The listed drawbar output is 81.3 hp, below the 150 hp benchmark average. For pulling work, the safer assumption is about 81.3 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the New Holland TV145?
The PTO-to-engine transfer works out to 72.4%, from 145 engine hp to 105 PTO hp. That is a noticeable drop, so implement sizing should be conservative.
How efficient is the New Holland TV145 for pulling work?
The drawbar-to-engine transfer is about 56.1%, from 145 engine hp to 81.3 drawbar hp. That means traction losses and drivetrain losses are a big part of the real pulling result.
Is the New Holland TV145 better judged by PTO hp or drawbar hp?
The drawbar output is about 77.4% of PTO output, comparing 81.3 drawbar hp with 105 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland TV145 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 TV145 engine stressed for its PTO horsepower?
The engine has about 4.3 cubic inches per PTO hp, using 456 ci and 105 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the New Holland TV145 make?
The output density is about 14 PTO hp per liter, using 105 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.
