Saw this attachment on a craigslist post (from a commercial advertiser) thought it was neat...
I'd have to way cost and advantage{or disadvantage} of something like this. The price may not be worth what it is actually capable of doing.
Ask the guys in the PowerTrac group about front mounted "backhoe" arms. They do dig but you don't have much depth and you need to move the tractor constantly to dump the spoils. As an occasional tool they would be useful I'd imagine.
I like my QuickSpade. The price is right and it takes a whole lot less time a d hassle to hookup than my BH for small jobs.
I can understand the quickspade, infact I noticed NT sells them, saw it in catalog last night, seems handy for smaller jobs. I was commenting more on the skidsteer front hoe.
As an aside, you need to consider that the QuickSpade comes in two versions. One works only with forks and that is what I have. The other version, more bucks, works with either forks or attaches right to a bucket. The point I wanted to make is that the QuickSpade attached to a bucket really only digs about 18 inches deep so it might be useful for shallow trenches or digging up a garden plot but it isn't going to dig 4feet deep unless you have or acquire forks. That might be obvious but it should be noted that the QuickSpade makes a lot of sense only for folks who have a stout set of forks already. I've never used bucket forks and maybe those would be OK but I'd be a little concerned about the lever forces that could be generated digging and what that might do to a unreinforced bucket. I use standard QA frame mounted forks.
I've seen skid steer backhoes that pivot like a real backhoe. As for the quickspade I'd be a lot more worried about bending the loader. Forks are highly unlikely to bend.
Not if they were of proper capacity to begin with. The tractor loader is still the weak link.
