I am actually about to order a walker brand new fuel ingected. I looked at the ex mark and there both good mowers but when it comes down to it the ex mark is slower heavier and doesnt have the reputation that walker has. Walker has extremely good respones to its hydro and manovarability plus they stand behind there product better. nothing cuts like the walker ive wanted one for a few seasons now. I have the money to buy it im getting it makes the properties look way better and cuts down on time. Lets face it there a reson why walker has been around for so long.
