New Holland 3930 Horsepower FAQ
How much PTO horsepower does the New Holland 3930 have?
The listed PTO output is 45 hp, below the 65 hp benchmark average. For real use, size PTO implements below or near 45 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the New Holland 3930 have?
The listed drawbar output is 38.2 hp, below the 55 hp benchmark average. For pulling work, the safer assumption is about 38.2 hp at the drawbar before soil, ballast and tire limits are considered.
Is the New Holland 3930 better judged by PTO hp or drawbar hp?
The drawbar output is about 84.8% of PTO output, comparing 38.2 drawbar hp with 45 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the New Holland 3930 engine?
The engine displacement is 201 ci, below the 260 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the New Holland 3930 engine stressed for its PTO horsepower?
The engine has about 4.5 cubic inches per PTO hp, using 201 ci and 45 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the New Holland 3930 make?
The output density is about 13.6 PTO hp per liter, using 45 PTO hp and 3.3 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 3930 rated at?
The rated speed is 2,200 rpm, close to the 2,200 rpm benchmark average. The 2,200 rpm figure is around normal for this class.
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.
