I'm stumped how to solve this and avoid a trip to the dealer. Left ESC grip fails to release all the way, pulling the mower of course to that side. If I nudge it forward w/the top side of my fingers I can get it to release all the way, but a complete pain in the arse....I have done everything I can think of (clean, lube, etc.) but cannot correct it. Dealer offers no tips, just bring it in and pay $$$. Any suggestions?
