I have the 6ft. squealer by bush hog. It's 3 seasons old now and has held up very well. It cuts nicely, is well built and was a far better deal than the land pride.
The bottom line is, I would buy another one and if I you knew me and I told you that, it's saying something for that particular product.
I have a Bush Hog rear blade that has worked out nicely as well. Would also have purchased a Bush Hog box blade this summer that I really wanted but the representative screwed me and the dealer over so I cancelled the deal and went to Tractor Supply and bought a King Kutter. Wasn't exactly what I wanted to do but the KK has worked out pretty well so far.
