New E gator owner

We purchased a used Gator TE.

The dealer is miles away. Documentation is mediocre.

It looks like it will do well for us if we can learn how to manage it.

We had to remove the drivers seat while recovering from a battery discharge. When we replaced it we were unable to secure it such that it would remain adjusted. It just slides. Anyone know what might be the problem?

Also looking for info on a roll bar, windshield etc for the TE.

Thanks,

bob
