Ha, well good to know. I will look those up and check them out. I run everything Stihl....it might be hard to switch brands! And yes, I go over my shrubs 2-3 times, each time either lightly raking or shaking my hand over them to get the clippings out and pop up any uncut areas. Some of these Wintergem Boxwoods get so top heavy the braches sag and you gotta release the weight and go over them a few times. it's a pain, but I like the results- it's something that's worth doing well and taking your time with.... Absolutely! My back and midsection gets tortured doing these jobs. Thanks for the word on the 45s! Might be buying some. Starting to do a LOT more trimming jobs. eeeeuuugh.
