I have used this subsoiler some around the house to pull a few small stumps and out in the field. But, I've got a few questions on how to use it properly. This particular one hinges in the middle.
When I hook it up to the tractor, the top end is heavier than the lower end. That causes the bottom tooth to swivel up against the drawbar. When I lower the lift arms, the tooth does not contact the ground, thus not digging. Adjusting the top link does not seem to help.
I thru bolted the subsoiler near it's top arm, which stopped it from swivelling. It made it in effect one piece, and worked great.
However, I would like to know why it is designed that way, (to swivel, and be counter balanced that way in the first place). What do I need to make it work correctly without the bolt through the subsoiler arm?
Any zen subsoiler gurus out there?
First pic is the subsoiler in the up position. Notice how the tooth is swivelled up against the drawbar, from the counter balance of weight.
Second pic shows it in a lowered position. The tooth will not contact the ground, thus not digging.
Third pic shows it with the thru bolt I added...(the swivel arm top), holding it in an upright position.

) I didn't like the way it tended to do what you describe, so I simply over-tightened the single bolt to where it wouldn't allow easy movement, and I'm satisfied. That one bolt should be a light grade bolt that will shear if the subsoiler hits that "immovable object".
