I have one that I bought used. It's actually a powerful little thing, I used it for a couple projects hooked to the hitch of my crew cab F350 and it would drag all 4 wheels (locked in 4x4, in gear, brake set) when I was using it to pull out 2-3 foot rocks. It digs really well. I have no clue how people use it for heavy jobs hooked to an ATV. The biggest pain is the non hydraulic stabilizers. To get the right leverage, you have to use the bucket to lift up the whole thing, drop the outriggers, pick them up until you find one of the 3 holes for the pin, then drop it back down and dig. If you don't get it right, it will just drag your tow vehicle around. So every 6-8 feet I'd be lifting the trencher with the bucket, pulling the pins and positioning the outriggers to the "up" position, getting in the truck, starting it, driving 6-8 feet, getting out of the truck, lifting up the trencher with the bucket, dropping the outriggers, lifting them back up to the nearest hole, getting back on the trencher, rinse and repeat. That and the mobility issue of getting a truck AND a trencher in the right location in the first place.
Is it better than a shovel? **** yes.
My father in law picked up the same tractor as me, and got a backhoe for it. I'm going to sell the DR, put the subframe mount on my tractor, and just borrow his backhoe for projects. I won't be sorry to see the DR go after using the BH on the
B2301, it's way more time efficient.
