Don't know how old your tractor is, but that looks like a job for your soldering iron. Drill a small (1/16th) hole at the terminus of the crack( to prevent it from growing) and thermal weld the crack
I'm not sure exactly what happened there. The tractor was at the dealer a couple months ago, so maybe it happened while it was there. I went to see the dealer and ordered another console under warranty. The tractor is a 14 with 50 hours. Just very odd at how it is cracking.
When you re install, look at how it is supported in the area. Maybe there is a ridge, or it is left to flex which is bad. Good luck. BTW - do not over tighten the mounting bolts either. On my Bobcat I used the soft Locktight and just snugged it up.
