I few weeks ago i notice a guy with a John Deere tractor with a front blade that had what appeared to be a serrated edge working on his driveway. This i know would be good for cutting sod as well as hard packed driveways. SO two things here. I would like to find out where i could get one of these. Also i talked to my friend that i bought the tractor from and he talked to the guy at WR Long and he siad that there have been a few people ask about this other than me. If he could find enough that were intrested he may consider adding it to his line. So if no one knows where to get these things we might could get WR Long to make one if enough expresses some intrest. If i cant find one then i am going to get a cutting edge and have the local machine shop serrate it for me. Post please and let me know.
