New Holland Boomer 25 Horsepower FAQ
How much horsepower does the New Holland Boomer 25 have?
The listed engine output is 27 hp, below the 35 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 27 hp.
How much PTO horsepower does the New Holland Boomer 25 have?
The listed PTO output is 19.9 hp, below the 28 hp benchmark average. For real use, size PTO implements below or near 19.9 hp rather than using a bigger engine-horsepower number.
How much engine power reaches the PTO on the New Holland Boomer 25?
The PTO-to-engine transfer works out to 73.7%, from 27 engine hp to 19.9 PTO hp. That is a noticeable drop, so implement sizing should be conservative.
How big is the New Holland Boomer 25 engine?
The engine displacement is 80.4 ci, below the 110 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the New Holland Boomer 25 engine stressed for its PTO horsepower?
The engine has about 4 cubic inches per PTO hp, using 80.4 ci and 19.9 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the New Holland Boomer 25 make?
The output density is about 15.3 PTO hp per liter, using 19.9 PTO hp and 1.3 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
What rpm is the New Holland Boomer 25 rated at?
The rated speed is 2,700 rpm, above the 2,400 rpm benchmark average. A higher 2,700 rpm rating can make power well but may feel busier under load.
Official information note
