I've been doing repairs for quite a while, and I have only needed a trencher a few times. However, I'm getting alot of requests for installs and have managed to land three in a row. I start my first this week, and am willing to rent again for this one if need be. I'm going to need to buy one to be profitable long term, however. I'm going to start my shopping for a trencher tomorrow. I'll report back sometime soon with my findings. However, I would like to know of any fair warnings one might have or recommendations before I go look and get an itchy trigger finger. I'm really liking the idea of spending the extra money and getting a mini skid that can operate lots of different attachments. As that will help the landscaping part of my business as well. Am I wasting money when I could just get the trencher for cheaper? Is a wheeled or a tracked model better in certain situations? Is there an industry wide preference for a dingo or a ditch witch? If I go with ditch witch what size model would best suit me? I'm leaning toward the ditch witch because there is a dealer here and they can repair/ supply parts. The other thing I was thinking was whether it might be worth the risk to buy used? I bought my Walker used and it has been a great machine. However, most people who have these types of machines are companies and not owner/operator types. Meaning that the guy who is driving it is probably not the guy who owns it. Which is scary. Enlighten me. Thanks.
