Got 10 of them and trying to get 4 running.
Going to sell the parts from what left over.
Have 3 NI, 2 NH 56, 2 NH 55, 2 MF and 1 IH.
Re-building one of the NH 56 this week and taking the other one apart, so I will have the parts ready to sell.
I rebuilt one of the NI last year and next week I am going to take the other 2 and make one field ready.

I always hated working on hay rakes! lol! ---the best one we ever had was an old AC pto drive rake. never had any trouble with it in all the years we used it.

I was working on one last year and put a rake tooth all the way through my foot.
Working on one in the field is not much fun, but in my shop it is easy going.
