I have a 6 foot york rake and have never been very successful using it. Its on a Kubota B8200. First off, i cant get it properly level at all heights, 2 to 3" lower on one side. I suppose the linkage is a bit worn on the 3 point. However, this rake has 2 wheels that follow behind. I have never used the wheels and am wondering what the purpose of them is. Im not working with truckloads of fresh topsoil. I usually filling in 20' depressions from trees stumps i removed in the past. Im working the 3 point up and down as i spread dirt which probably isnt right. Any suggestions.
