Okay, the simple angle I have to hold while edging kills my back as well. Even with the strap I have issues at times. Course I have about 300-400 feet of edging to do in the front only. Wonder if I need a super wonder bar?It promotes better posture for tall people.
I bought mine to save my back. Being hunched over, while using a weed whacker, causes me a lot of back pain. A trimmer strap doesn’t help me one bit.
