NH 311 Baler, pickup weak from getting stuck on a hump

Hi Folks,

Hope those of you that are able to stay home are getting an early start to equipment prep. That is what i've been up to and I wanted to get a little advice before I try to tackle my baler.

The last field of last season has a hump running down it and i can usually rake to either side but there were sections when my windrow went down the hump. During these stretches the pickup teeth hit the hump and usually will power through it, but I got hung up a few times to the point where they stopped. I stopped the tractor and had to set the teeth up high and carried passed the hump, then dropped the pickup back down.

I noticed as i finished the field that the pickups were having a hard time pushing the hay passed the spring loaded hay keeper jaw (forgive me i don't have my manual with me and can't remember what this part is called). So hay was building up (especially on one side) and i had to keep the RPM up and ground speed down in order to not get backed up with hay, which messed up my strokes per bale.

Is there an overrunning clutch or something i need to adjust/replace in order to get power back to the pickups?

Thanks all, stay healthy.
 
you may have a tooth on one or more of your pick up teeth not running in the correct slot causing pickup to slow down even occasionally stop. You may have to take off guard or 2 to get it back into place. Not a big deal.
 
You might have bent the rail that makes your teeth go out at the bottom and retract at the top. My IHC 430 acted like yours. The cam or rail wore out. There were bearings supposed to run on rail or cam. They were gone. Now baler has over double the capacity. My teeth were retracting to quick. It happned so slowly I didn't notice till I was in 1st gear and still wouldn't take a double windrow.
 

I'll advise to check operation & condition of pins & clutch hub associated with pickup drive chain.

Thank you all. I will investigate and report back with whatever i find. Hopefully this weekend, but it seems every time i cross something off my list, two more get added back on.
 

Hook it up and run it with the pick up in the raised position. You will quickly see if it is turning easily or where there is a bind. Be careful. You can turn it by hand but it is slow. You can feel the resistance when you turn it by hand.Sounds to me like you either have a bit tooth dragging on the guard or a bad cam bearing or a weak clutch. Might be all three.
 
Secure the pickup at a predetermined hight. Then it may float over the hump better than just letting the little gage wheel carry it. If there are holes,furrows,etc,then adding a dual tire to both pickup,and pickup side of baler can help to keep the pickup out of the dirt.
 
Been years since I ran a baler but I think his problem is in same area you had trouble. I cannot se a bent tooth stoping the pickup and hitting that hump was just enough to make it let go in what drives the pickup bars.
 
If you are turning the pick up by hand and its not binding up or catching something, I would agree with TXJim on examining the clutch. If you need replacement parts,
etc., you should contact Esch Hay Equipment in Gordonville, PA (one town over from New Holland) and speak with Junior, he is an expert on 311's and their pricing beats a
dealers.
