I needed a 54" lawn tractor. It was either the D170 or the X380 54. The X380 is $1900 more and too much for my second mower. My main mower is a JD Z525E 48. In fact I went to Lowes a month or so ago and bought one. Went home and read the bad reviews. Didn't sleep at all and went back next morning and canceled the order before being delivered. After another month of indecision I went to Home Depot and brought my trailer. They gave me a 10% veterans discount and I bought their Protection Plan which added 3 years to the factory warranty for a total of 5 years for $349. Plus they'll come to the house for repairs. One thing that the D170 has on the competition is the discharge hole is big and open. All the others have a bar across the bottom of the hole. I occasionally get into tall grass and sometimes it can get clogged up on my old mowers. For my needs the D170 is a good fit and hopefully will last a long time. What is your opinion on the D170?
