I have adjusted the torsion bars on the front shell of my 2720 just this season. It seemed to take a little more " umph!
" to raise it than it should have or used to. Before you go adjusting make sure the TM is level and that you are grabbing the shell in the front middle as best you can. I only had to tighten each bolt / bar 1/8 of a turn to put the " spring "
back into the lift system. Does not sound like much but it was just enough. Be sure you turn each bolt in the same direction by the same amount. Let us know how it turns out!
