FWIW, I also use nylon washers on the hood bolts of my cub and they work really well to keep vibration down and the hood stays exactly where you put it just like the picture shows. Interesting idea about the cork in the back. I still have a little of the remaining rubber strips on mine but they move around a lot with the vibration between the hood and the dash.
Thanks for all the feedback on the front bumpers, I'll try some heater hose next time I work on the cub. As for the 1x2/3, I've never seen anything to dampen the hood on the front of them but I'm certainly not the authority on the subject.
We're starting a collection for a co-worker here at work. His 3-4 year old Simplicity 18 HP lawn tractor has broken it's frame. ANY and ALL donated Cub Cadet parts would be appreciated to This Nice guy can build himself a REAL tractor. hehehehe. He's kinda in the same boat as the Guy a week ago on the YT JD board who's LT166 needs $3000 worth of hydro repairs and it's less than 5 yrs old. Sure makes a $500 35 yr old Cub Cadet look like a Great Buy doesn't it?!?!?
