Just bought my universal deck dolly for my Snapper GT600 with a 60" deck. The deck fit on as advertised,and it supported the deck for all maintenance. Since my deck weights 258 lbs., I ordered the optional dual wheels and the soft surface feet.
Ever since we purchased our Kubota BX-25D tractor. The 60" drive-over mowing deck is very nice feature. Next comes the maintenance and storing the deck. We (my wife and I) would use a lumber and a utility dolly to muscle the deck into position for blade sharpening and storage.
Since purchasing the Universal Deck Dolly, I have say, I actually don't mind lifting up the deck to sharpen the blades, greasing all fittings and thoroughly cleaning the deck top and bottom.
There's no design changes I'd want to change. A truly well thought out product.
you will not be disappointed.
