My driveway has a portion that has a steep rocky bank, where I have two 2 X 12's . One end is resting on four milk crates ( two high ) I mostly use them to drive my lawn tractor onto so I can clean the under-side of the 54" mower deck with a garden hose .... well the grass grows quite well there and I could only use a String Trimmer to clear it .... well today the grass and plants were so thick the Trimmer wasn't doing a very good job .... Then I thought of trying my Electric Hedge trimmer It worked waaaaaaaaaaaaaaaaaaaaay better than the String Trimmer and waaaaaaaaaaay faster .... good luck .... Mike
