New Holland Boomer TZ18DA Horsepower FAQ
How much horsepower does the New Holland Boomer TZ18DA have?
The listed engine output is 18 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 18 hp.
How much PTO horsepower does the New Holland Boomer TZ18DA have?
The listed PTO output is 13.7 hp, below the 28 hp benchmark average. For real use, size PTO implements below or near 13.7 hp rather than using a bigger engine-horsepower number.
How much engine power reaches the PTO on the New Holland Boomer TZ18DA?
The PTO-to-engine transfer works out to 76.1%, from 18 engine hp to 13.7 PTO hp. That is a normal usable range for judging PTO implement fit.
How big is the New Holland Boomer TZ18DA engine?
The engine displacement is 58.2 ci, below the 110 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the New Holland Boomer TZ18DA engine stressed for its PTO horsepower?
The engine has about 4.2 cubic inches per PTO hp, using 58.2 ci and 13.7 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the New Holland Boomer TZ18DA make?
The output density is about 13.7 PTO hp per liter, using 13.7 PTO hp and 1 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 TZ18DA rated at?
The rated speed is 3,000 rpm, above the 2,400 rpm benchmark average. A higher 3,000 rpm rating can make power well but may feel busier under load.
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.
