Massey 124 Baler packer finger adjustment help

Well today we baled hay with our 124 massey for the first time and things went well. I cut just enough to test a few bales. Bales are square and knotters worked fine which is what I was most concerned about. The only issue is that bales are 36" and weigh 78# They are like concrete blocks , you couldn't drive a nail into the bales. I have baked off the bale tension springs a bunch and we will try again in a few days as it is raining now.
The question I need help with is about the packer fingers adjustment. There are 3 positions a pin is placed in to make the adjustment. When I got the baler this pin was in the bottom hole and I have left it there. I can see that the bottom position causes a faster movement of the packer fingers and they go further into the bale chamber. I have the Massey operator book, it is a little light on information. It says the pin should be in the center hole initially but can be moved to a different hole for extreme conditions or abnormal flow. Thats all the information the book gives. Can anyone tell me what moving this pin changes in the baling operation and how the bale would be affected? Would this position setting affect bale density? Should I move the pin back to the center position? Thanks Bruce

If I recall that adjustment is for moving crop in the chamber deeper/shallow if needed for even packing of the bale, side to side. I don't know if the dealer I worked for ever moved those pins on any baler we sold. A good working 124 will keep two fellows busy loading..

Dieseltech is correct, its to correct curved bales by packing more hay on one side to compensate. Shouldn t change bale density overall. On my old model 3, the pressure bars need to be set quite loose. Of course damp hay will pack even tighter.

I agree with everything being said,but once you start baling,and you get your travel speed up a little, the bale wont be so tight, the more time's the plunger goes back, the tighter the bale will be. I use to count the cycles, i think it was 12 or 13,in a good swath of hay, to make a nice 50-55 lb bale!

As the other guys said it is not for density it is for how far across the hay is put. Your problem is simply that your hay is not dry. Do you have a tedder?
