[AT] JD 214 WS timing problems

[Brad Gunnells]

Actually the needles clear the plunger, not really the other way  
around. The plunger is at full stroke compressing the hay in the  
chamber. The needles pass up through the slots in the plunger to lay  
the twine/wire into the knotter. The knotter assembly wraps the knot  
and cuts the twine/wire. Then the needles retract and the plunger  
rescinds. As the hay leaves the bale chamber it expands from it's  
compressed state and causes the knots (in twine) to tighten.

The stop that is being hit by the plunger is there in case the  
needles move from their parked position before the full stroke on the  
plunger. Otherwise the compressed  hay would likely bind or break the  
needles. The needles never really touch the hay, they merely are the  
transport to get the bottom side twine/wire passed up to the knotters.

Funny how intimate you get with the workings of these thing when they  
don't want to cooperate.
