The same issue has brought me to this site.
I have recently purchased a new Cub Cadet LTX1050. I love the mower and its been great except for the fact that it just recently started leaving a strip of unmowed grass approximately 16" from the outer left edge of the mowing swath. When I get under the mower and measure in, it appears that this is the space where the left and center blades meet. I just installed new blades and it doesn't seem to have fixed the problem.
I really like this mower and didn't have this issue for the first 10 hours. Does anyone have any suggestions for me?
Thanks!
