New Holland TZ21D Horsepower FAQ
How much horsepower does the New Holland TZ21D have?
The listed engine output is 21 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 21 hp.
How big is the New Holland TZ21D 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.
What rpm is the New Holland TZ21D 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
