I am happy that the dealer and walker worked out the problems for you! Walker has been top notch for me with my MDD and with newest upgrade. There tech support is amazing! They do build a top notch machine. Most of the walker problems on this forum have been with (Kohler engines and Eaton hydro pumps) I think with the newer eaton pumps having the improved check valve you will see far less failures. Along with improved steering having no stress on hydro control arms, (available as an upgrade).
