I figured I would share a personal experience. I usually in the interest of time fill the big green barrels to the max with wet grass, leaves, or whatever and throw them in the back of the truck. Well it finally caught up to me because a few weeks ago I was lifting some grass and I got a sharp pain and dropped the barrel. I was in pain for a couple weeks and decided to go to an orthopedic doctor. After X-rays and MRI's it was determined that I tore cartilage in my shoulder. Luckily it is not a rotator cuff injury because that's a ridiculous recovery time. I will be getting surgery in January (my biggest down time). Recovery is 2-3 months. I'm going to have to man up for the next 2 1/2 months during leaf season and deal with the pain. Luckily I have a great worker who is really helpful and just hired another helper for the fall (and next year) to pick up the slack. I'm not looking for sympathy, just trying to tell you guys what happened to me so maybe other guys won't load the barrel to max capacity and hurt themselves. Hope I didn't bore anybody with the long post. Thanks for listening.
