I have two sulkies for sale. 1. trimmer trap brand rocket wheels $200 a few years old but used very, very, very little- looks like new I bought this and was going to run it behind my hydro wb, but sold my walk behind so no longer need it. This is the syle that stays fixed behind the mower, and the tires are the only thing that swivels. 2. Jungle Jim brand pull behind sulky $75 approx. 8 years old, used a lot, It was a friend of mines It seems a little sloppy(as far as the bearings go) he said it could use some new ones, but he said that if he didn't sell the walk behind to me he would have just kept using it. He said you just have to keep it greased up real good. I am very proactive about everything and would just put new bearings in it. J Thomas sells these bearings for $4.55 a piece and it looks like there are 4 of them. J Thomas # is 1-800-828-7980 call me at (937)456-2826 that is the best way to get a hold of me, just leave a message. I will email pics to you. These will make somebodys some good usefull sulkys to keep you fresh for the next job.
