I noticed that my snowblower lift cylinder was leaking last year, and it is also 3 years old. Since this cylinder is common to a lot of other Kubota products, I picked up a spare this past summer that I will swap with the K Connect cylinder. Then I will rebuild that cylinder and hope for the best. I have the identical cylinder on the chute deflection and my snow plow. For both of those items, the cylinder is a lot older and has never leaked. I believe that Kubota just had a bad lot, and everyone is paying the price of having to fix the issue. They are only warranted for 1 year from purchase.
