I have the L3700SU which is the same power train from what I found. The hitch has note bothered me so far. 29 months old and 180 hrs. I have used a box blade, disk, bushhog, chisel plow, finnish mower. Nothing at all negative so far to say about it. My 11 year old daughter loves to drive.
What I've learn about the 3 pt hitch on the basic L is (when raised very slowly) it moves in 1/4" increments. Some people interpret this as jerky and some machines are worse than most are.
Like I've said before, I do not notice the 1/4" increments in normal operation.
