It really amazes me as to the stuff it will go through. Like I said, I got it to cut the levees ( 1500ft ), and they were getting out of hand. Some of the small trees and bush had grown to 1.5 to 2 inches in diameter. When you came up to the big stuff, I went very slow, or else it would break over center and release the belt. It has really helped in the mowing chores. Sure beats a kaiser blade. It is a 7 ft Deere and I gave $700 for it and that included a new knife section. Got it from a golf course.
