Does anyone have any information on the Hydralic deck lift soon to be available onthe Hustler Z models. Will it be a retro kit for all Z models or only available on the new mowers upon release? Will the new mowers with hydralic deck lift still have the manual foot lift? What is the release date to dealers? What is the MSRP? What are the pros and cons of the hydralic lift? Any other information would be appreciated!
