When dad & I first started in 2002, we started with new equipment. In doing so, we also learned how fast new equipment can look like old equipment when first learning the techniques. Sometime during the learning process, the sides of the deck got bent inward a little bit & sometimes rub on the blade. I am wondering if there is a way to straighten out the sides or if I need to be thinking about replacement. If replacement is necessary, is there aftermarket parts or just OEM.
