Can you guys that have used a Bobcat RockHound/ Soil Preperator(sp???) let me know what you think of this deal. I have found a used one that has a good amount of slop in the chains and the guy says that it will hop when you are using it as the chains go slack, then tighten up. The adjusters are almost all the way out as well. He wants $1800, half of new. The rest looks OK, needs a couple of hoses as well. Depending on what you guys say, I am thinking of giving him $1500 as is, I will fabricate the adjustment to get a little more out of it to make it taught. I guess my main concern is the effect of having loose drive chains. Does it make a difference? I have a couple of projects I could use this on right away, but don't want to blow good money on a piece of junk. Thanks for any help or suggestions.
