Thanks for sending me the stripe kit; it does a great striping job...however I have removed it from my mower for safety reasons. Upon first inspection I wonder how it would do on humps, backing, and uneven ground, in conclusion it is awful on all three. Upon final installation the first problem was the deck would not raise to the top position, the kit and the deck brackets hit each other. While mowing if you are on a hump it bottoms out. If you decide to back up on a hump, well, dont do it unless you want to plow to ground. Hills are also a BIG problem. Today I was mowing an uneven area and backed up onto a small hill. Once the back tires went up on the hills the bracket swung forward and functioned like a kickstand I was stuck. After finally after rocking the mower back and forth I got the mower and about 6-8 of grass out. The stripe kit was now stuck in a forward position under the mowing deck. When trying to get off the lawn I got stuck again and once again when I tried to get from the curb to the trailer. I ended up stuck on the curb going in circles and had to remove the kit there before I could mow again. Thank god no sprinkler heads where in the way. I also hit a small stump while backing and stopped rather quickly! I suggest recalling these before damage is done to a mower, property, or someone.
