790 problem lift arms hitting tires

Charlie_in_WV · May 15, 2014

This started "maybe" last year with my big, heavy overbuilt grader blade.
Then with the brush hog occasionally.
I corrected it with the brush hog and spreader by using those chains that come with the equipment BUT with the tiller, it just pulls those chains apart.
Those "turn buckle" adjusters are all the way in BTW and up to last year never have had a problem.
I have hillside (hillside? in WV?) food plots that I put in annually and this arm/rear tire issue is giving me some serious grief.
Heavier chains?
Turn the turn buckles out?

Here is the way my 790 3pt is set up. Is anything bent on yours?

Wow!
So nice and clean ∙∙∙ and the tread on those tires!
Not that I know of.
I have had to replace the left hand lower lift arm twice - once caught a rock with grader blade and the other time slipped into my ditch while brush hogging and had to yank the tractor out with my truck, the brush hog caught and $137 dollars for replacement later.
I'm going to try backing out those turn buckles and see "what" happens, thanks for the reply.
WOW!
Your 790 looks like it just left the Deere dealership, it's nice!

If you look t the picture closely, you can see some spacers that keep the lower link arms closer to the center of the tractor. I would check to make sure those spacers are in the correct location. If not, I could imagine the arms hitting the tires. The photo shows correct placement of those spacers.

Just a thought here since this is likely an easy answer and maybe this is it.

:laughing: Those are old pics. It's still nice but not that new.

Posting some pics of your 3pt may help others diagnose the problem.

Charlie what do you have on for tires and rims? There maybe solutions there.

Okay,
FIXED!
Seems the left hand side turn buckle eased itself out probably less than three quarters of an inch and THAT was causing the problem.
Amazing that a few turns could cause such a difference.
Too bad I usually learn the hard way, now my rear tires have little chunks out of the cleats.
Thanks guys!

There is a spring that hooks to loops on the inside of each of the arms and pulls them together. I think you are missing this spring. You could buy one from the dealer or use a rubber bungee cord.
