Why is it next to impossible to change deck height on these. Right now I'm slowly remembering what a pain wheel horse mower decks are in some ways. I had a Raider before with 36 rear discharge but swore it was no problem changing the deck height. Nothing seems outta place or bent. But getting the handle to unlatch to move wheels up or down is almost impossible. Sometimes I can't keep up with my grass so mowing a little higher helps but anytime I need to I'll have to unhook level rod put wheels where I want and relevel again. Or is that just how it is supposed to work ?
