My wife ordered the Tractor Supply toolbox for me as a birthday present and I installed it today. I must say it worked, fit, looked better, and was heavier than I thought it would be. It was a fairly easy install and only took about an hour. I made a couple of modifications and improvements that made it even better. They offer it in two sizes, a 16" and a 20" and your toolbox can't be too big, so I asked for the larger one. They are both the same price anyway. I lined the bottom with a 1/8" rubber pad and put weather stripping inside the lid where it meets the sides of the box and then cut off the little carrying handle on the box after I ran the tractor for awhile. I was attempting to limit metal-to-metal vibration noise (aggravations). And, it worked. It is black, but close enough to Kubota gray that I am not going to repaint it. I took a picture of the worthless OEM toolbox and my new TSC replacement. It really worked perfectly on my MX5100. The kit included several types of mounting brackets and thumbscrews to secure the box to the brackets. There is an indented area for the thumbscrews. The kit is well thought out and easy to install. I still have full view of the 3 point hitch and attachments and plenty of seat room with the seat moved rearward. For my applications this is a winner and reasonably priced.
