I just bought an X320 2 days ago and so far I've been pretty dissapointed. I've had an L120 for the past couple of years and thought I'd upgrade. I expected a better cut but I didn't get it. I emphasized to the dealer that a smooth cut was my number one priority and must have mentioned to him at least 4 times to ensure they leveled the deck prior to delivery which he insisted they would. After delivery, I brought the mower to my back yard, set the deck level to 3 inches, adjusted the anti-scalp wheels to 1/4 inch off the ground and engaged the blade. Within the first 4 feet I scalped the grass on the right side. Several more nice circles appeared in the grass as I slowly went up the small hill towards my back porch. My smart a** friend immediately pointed it out "ha ha you scalped the yard". My wife is also watching me test drive my new $4000 dollar lawn mower and probably wondering why I spent so much money on something that cuts worse than my old L120. I immediately disengaged the blade and put the mower on level ground. I lowered the right side anti-scalp wheels another notch and did a few more passes in the back yard. The right side was still cutting lower than the left. Today I brought the mower into the garage and checked the deck. Sure enough the right side was lower than the left. I leveled it out and took it out for some passes in the front yard. I somehow managed to scalp the right side again if I was at even the slightest angle. I also noticed about 20 dead spots in the grass in the back where I mowed the day before. This leads me to believe that something is leaking from my new mower and killing the grass. It did seem to be sucking down the gas pretty quick. I have 1.5 acres with some hills/small bumps and slight banks. I'm going to the dealer tomorrow to talk to them about returning it. I'm thinking about replacing it with a Simplicity tractor due to the full floating deck. I'm pretty anal about my yard and just want to find a mower that won't scalp it or leave an obvious lower cut on one side or the other. Anyone here have experience with Simplicity tractors full floating decks on small bumps and angles? Thanks.
