The wife and I are looking to buy a new mower. She will be doing most of the mowing because according to her, I tend to mow everything including flowers and scrubs, down. We have about 3 1/2 acres to mow total. She has used an Ariens GT-17 for over 25 years and would like to stay with the lawn tractor style of mower. She has spent some seat time on a friends Cub Cadet 1045 series and an Exmark Lazer Z and didn't like either. The Exmark made her back sore and the Cub Cadet was too loud. Seriously looking at the John Deere X-500 series and she has ridden on one at a dealer and liked it. Personally, I like the X-700 series better because it's more in line with the Ariens GT-17, but it's a little too spendy for us. Would appreciate hearing from anyone that has experience using the X-500 series John Deere. Thanks!!!
