3-Point Hitch How To Avoid Bending Lift Arm Adjuster ... (Again)?

[Diggin It]

Noticed this as I was hooking up the BH this morning. I'm pretty sure it happened while using the Landscape Rake since I had to adjust them almost all the way out to get the spread for the pins. But I'm not sure why it happened or how to avoid doing it next time. There are no stabilizer arms and I don't see a way to add any. Thinking maybe a threaded rod coupler all the way on then backed out to the turn buckle to add strength?

I can not see or imagine the entire image,, so I have to "guess" what I am looking at,,,

A LOT of "redesign" occurs,, and is shown on the forum,,

These components like your rod, were only intended for use in tension,,

An attachment is "re-purposed", which results in compressive force on the rod,, Oops,, the rod bends,,

Can we see more??

They usually bend like that when you back into something.

Nothing redesigned.

BH is on now so lift arms are raised and I can't get a decent 'now' picture. These were taken for another reason but show them fairly well (orange arrows) Red arrow points to what was bent and shown above.

The only way it could probably bend like that is being put into compression, which of course they are not designed to handle. The way to avoid that is proper adjustment so that when the implement sways side to side, one link goes into tension and the other goes slack.

Normally the link attachments are designed so this automatically happens (one side will slack rather than compress) but there needs to be the right amount of slop. If the load side never goes into tension before the slack side runs out of space to slacken, then it could get pinched and bend.

I always give implements a quick eyeball to make sure the links behave properly. It can vary with height on some tractors, so check it high and low to be sure.

Well, this was the first time I used the rake, so I'm not really sure if I had it adjusted right or not. But I also had the carry all on and moved a few pallets, so maybe it was backing into/under those.

But that's why I was asking about a rod coupler to increase the overall diameter of the shanks.

I wouldn't take that approach since it doesn't address the fundamental problem and may end up causing something else to break worse. Just adjust the stabilizers carefully so that they cannot get pinched and go into compression. You always want one of them (the one opposite of the sway) to go into tension and take all the load. The other will become slack and loose in that situation and not do anything.

don't back up with the implement on the ground.

Mine are busted, did you figure out a better solution? Wonder if anyone makes a kit with the bar/pins for easier adjustment? The factory arrangement does seem cheezy, not sure if I will replace with factory parts again or not.

You have to be careful with the bars too. I have tubes with plates that slide into the tubes on my B series and I bent one of mine slinging a brushcutter into a stump on a turn.
