whats up guys. I install about 3-6 irrigation systems per year, but would like to do more and am thinking of buying a used trencher. For a small system I rent a ditchwitch walkbehind trencher, for a big one I rent a big ride on trencher. the ride on is quick and digs deep but is expensive to rent and too big for some applications. the walk behind is cheap but takes forever to go through hard ground and roots. I guess my question is how good are dingos? I've never run one, but it looks like they would be a great cross between the two machines. they also come with a bunch of other attachments which is a plus. Any thoughts would be appreciated!
