I am looking at buying a NH 640, but I do not know if my tractor will pull it. I have a 2520 JD with max pto of 61 hp. The baler also does not have net wrapping, is it possible to put it on the baler. Thanks in advance.

I have been baling with a 640 for a couple years now. The manual states that a tractor of "at least 60 hp" be used.

I have pulled it behind a JD 3020 (64-71 HP)and it does just fine even on the hills of east central Ohio. My concern isn't power, but having a tractor heavy enough that it doesn't get pushed around on hills when the bale chamber is full.

In dusty hay I have had to stop to clean chaff away from the twine knives every 50 bales or so to keep the autowrap working properly. No big deal.

It is possible to add a net wrapper to the baler. I checked into it myself. I found it to be too expensive for the benefits achieved. I chose to apply the money to building a hay barn for round bale storage. I can use the barn to store equipment as well, and the hay never gets wet!!

Good luck with your decision!

Net wraps usually require a different monitor and a different wiring harness other than the one a standard baler of any make has installed. I would not invest in putting a new net-wrap on a used baler. It will cost you 10-20% more than if it came OEM on the baler. If I wanted a net wrap baler I'd look at used one that already had the net-wrap installed or a new one with net wrap.

Should be ok at 60 hp. My dad and I each have NH 650's and running a 4'x5' bale (will run a 4'x6') he pulls his with a 5600 Ford some of the time (at 62 hp). It does ok except on steep hills, then wants to run hot. Mind you 86 hp does a lot better but 60 will get you by.

I looked at net wrap but decided that there were way better ways to protect hay without having to fight all that old netting. Going mostly to tube wrapped baleage now.

The idea behind net wrap is not to protect the hay (or straw ) from the weather as such, it is to speed the job up. When you stop to wrap the bale with net, the bale only has to spin twice around or so compared with say 12 times or so when wrapping with twine, before the bale is ejected. The vast majority of round balers sold over here are fitted with net wrap for that reason.

You are on the lower edge of the HP range for that size baler. If you are a flatlander, you probably will be OK. If not, your power will be marginal or less on hills. Netwrap was an option on 640's, but it isn't feasable to add to an Autowrap baler. A well kept 640 should be a good baler.
