I don't know what a Kubota RFM used is worth but I have a Landpride 6' RFM that has only been used 6 to 8 times. Paid $1750 for it about 4 years ago and am asking $950 for it because Barlows said that's about what a used one sells for. The Landpride is built like a tank. I had a cheap one before buying the Landpride that tore up alot but my yard is not golf course level. Hope this helps you decide on your price.
