How much drawbar horsepower does the New Holland 5640 have?
The listed drawbar output is 60 hp, close to the 55 hp benchmark average. It gives a realistic pulling-power figure of about 60 hp.
How much engine power reaches the PTO on the New Holland 5640?
The PTO-to-engine transfer works out to 83.9%, from 78.7 engine hp to 66 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the New Holland 5640 for pulling work?
The drawbar-to-engine transfer is about 76.2%, from 78.7 engine hp to 60 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the New Holland 5640 better judged by PTO hp or drawbar hp?
The drawbar output is about 90.9% of PTO output, comparing 60 drawbar hp with 66 PTO hp. That helps separate pulling ability from PTO implement ability.
