I have a Woods "Groundbreaker" hoe on my L 2500 Kubota and it works great. Obviously, it is not something for commercial use but it sure will dig. I also have a Bro-Tek Thumb on the hoe. I have been using it for several years to lift stones, logs etc., with no problem. I can't imagine why Kubota or Woods would say the metal is too thin, maybe for welding a thumb on but the Bro-Tek thumb bolts on, Google Bro-tek Thumb and check it out.
