I purchased what I was told was a Gray Market Kubota. I think I'm the 3rd or 4th owner. I'm not sure of the model number, there wasn't one when I bought it. I believe it is comparable to an L3500. It is 2wd and a 3 cyl diesel. 1908cc is stamped on the engine. The plate on the side of the engine is unreadable. I'm looking to purchase freeze plugs as mine started linking with winter. I would also like to know the model if possible. Thanks for your help.
