HVT52 The Husqvarna HVT52 hover trimmer floats on a cushion of air! This model is suitable for professional work in difficult terrain. The four-stroke engine can be used on slopes of up to 45°. The HVT52 has very low vibration levels in the handle and the trimmer line can be easily replaced. I saw one today at a dealer and was wandering how good it would be for trimming large banks/steep slopes. Has anyone seen or used one....what do you think?
