I’ve been looking for a Honda HR21. I’ve seen just two of them for sale locally and they both have the same problem- the aluminum desk is corroded thru toward the back end. The affected area is the vertical wall of the grass chute area and some of the horizontal surface next to the drive belt cover. One mower looked like it had a fairly tough life and the hole was huge on that one (maybe 6-8 sqin) so that clippings were being blown into the belt housing. The other one seemed very well cared for and the hole was maybe 2-3 sqin. My question is – do they all rot away like this or is there some chance of finding a solid one if I’m patient enough? And, is there any good solution to do a repair on it? Thanks!
