I have had the" jerky" steerting and irratic lift operation issue on B since it has had about 200hrs on it. It now has 394hrs. on it. After reading Butch's fix for his B series I went to my local Kubota(where I have purchased $60K in stuff). He said he had never heard of the problem and knew nothing of the kit to fix it. I gave him the part number for the kit and asked him to contact his DSM to try to get them to cover just the cost of the kit. I asked him to go ahead and order the kit because it had got pretty aggravating with the steering and lift. Well, my dealer said his DSM was not going to help at all so i'm out $185 for a kit designed to fix a problem that Kubota. I must say in fairness that I have 3 Botas and this is the first thing I have ever had a problem with. I think they are great tractors but this has left a bad taste in my mouth toward them. Seems sorta arrogant to me on their part. I have contacted Kubota USA again and asked them to please help with the cost of the part. Will keep you posted on their response.
