[AT] now 3pt hitch

[Dean VP]

Herb,

Here is chain/clevis concept that might  lead you to a solution.  On JD's
800 series hitches the anti-sway chains attach to the drawbar though
clevises that allow the chain to have as much room in the fully upright
position as they do when the draft arms are down but yet provide ant-sway
properties. They do this with a clevis loop that is much higher at the top
than it is at the bottom of the chain travel. So the chain essentially
slides up and down on the clevis to provide more room when the draft arms
are all the way up. But still provides the anti-sway property. They slide up
and down vertically but the horizontal dimension doesn't change. I don't
know how your chains attach to the pivot point but this concept might lead
to a solution for you with a little farmer ingenuity.  See the picture of
the two clevises that are attached to the drawbar and chains.  I'm sure the
concept will be obvious to you.

On the AC720 L&G tractor the pivot point for the 3pt anti-sway chains is
different than the pivot point for the two lower arms, causing the chains to
tighten/loosen as the implement goes up/down. Very undesirable, and can be
dangerous. I tried Dean's "Band-Aid" of adding washers; result was the
implement did not flop around when lowered, but the chains tightened when
raising the implement so that I could hardly get the implement clear of the
ground. And there is no easy way of relocating the pivot point to its proper
location.
Result is I cannot use AC720 for close cultivating in the garden.  Maybe
this winter I can find time to reduce the significance of this undesirable
situation.  Herb(GA)

I own a few Leinbach implements all the way out here on the opposite coast.
They have performed quite well and have no real complaints.  I did have one
problem with their scoop. The three point pin spacing for the draft arms
were too narrow for my JD 750.   Since the anti-sway chains on my JD750
attach to the inside of the draft arms, even with the absolute minimum chain
length, I couldn't keep the scoop from hitting the rear tires.  .As a
Band-Aid I added at many washers to each mounting pin as I could to spread
the draft arms and that helped a whole bunch. I Haven't taken the time to
find out which, the tractor or the scoop, didn't meet the ASAE three point
specifications. At this late date is kind of a moot point
