LEVELING A MOWER DECK

[KEYBEAR]

I have a 60 inch drive over deck and it is almost a year old . I have a problem keeping it level from side to side . The two adjusters used to do this use two long bolt,s and I think they may be backing out and letting one side move down ? I level it and after 10 or so hours of mowing the left side is low maybe a half inch .
I am thinking of putting a lock nut on them .

A lock nut or just a black marker pen to note if there is any movement like "backing out".

If I knew the Thread of that bolt I would just put a nut on it and call it good . I may watch it until I remove the deck .

Rain all day today so I pulled the deck off . Everything looks good so I added a lock nut will see how that works .

Did you check the tires to see if one side is loosing air?

I had a 770 with that system. It did not work well on slopes as the deck would lean. I was going to ask about the air in the tires as well.

Just put new tires on it last week the original tires no problems with air and so do the new tires .
