I went to the dealer(45 miles away)that handles Walker in my neck of the woods and they had dropped the Walker line. Couldn't sell enough of them according to the owner. On my way home I visited my JD dealer and demo'd a JD M655(on his lot). The 7 iron deck was very impressive and I told him I needed a demo with a mulching kit on one of my properties with a lot of leaves. Area rep is supposed to get up with me to schedule a demo. Choice is now between Exmark and JD. Any JD ZTR owners out there that can give me any feedback on these machines. I currently have 3 John's(950 and 855 tractors and a 285 mower) and have been satisfied with their performance for what they were designed to do. JD parts are high but the dealer gives fair service. How do Exmark parts compare with JD?
