I wanted to tell my story about having to replace a rusted out rear rim on Kubota L 3600. The rim I could not find a used one anywhere in the USA so I went to Kubota dealer and purchased a new one (size 17.5 X 24) for $300.00 then the service call to come out and change this out was $260.00 I went ahead and put tubes in both rear tires while I had him out here. The tubes were $130.00 for both, I had him to take the calcium out of the tires and put methanol mixture in 30 gallon at $8.00 per gallon for a total of $240.00. the total cost for replacing the rim and all plus the rim was $930.00. I hope I do not have to do this again. One thing I kept the calcium and put it in barrels and uses it for grass and weed killer after just two days it has already started killing the grass and weeds.
