I am in need of a 3rd function valve for my BX23S, however, I don't know which one to buy, the Land Pride or the Kubota. They both offer a model that is specific to the BX 80 Series tractors and Land Pride has a model that is specific to the BX23S model. Having done a lot of reading, I have learned that the Kubota unit is a bypass unit, and that the Land Pride is a full time 3rd function valve. I have found and read the instructions for installing the Land Pride valve, but haven't been able to find the instructions for the installation of the Kubota valve. Do you have either of these two brands 3rd function valve mounted on a BX23S, and if so, how happy are you with its function? My dealer has installed the Kubota units in the past, but wasn't even aware of the Land Pride unit until I brought it to their attention. Here are the install instruction specific to the BX23S http://messicks.com/uploads/assets/380-289A_color_copy.pdf . Cost from Messicks for the Land Pride Unit is $837.44 for the parts only. Installation is extra, however, I believe that it isn't that difficult if you can read and follow the instructions and the install PDF.
