For all those that use their 4100 or up with HST to bush hog in heavy brush, be aware that the safety (deadman) switch on the trans is at the bottom of the trans and easily pulled off in heavy brush. I found that out the hard way after an hour of trying to get the @#%#@@@ thing going a 1/2 mile in the woods. finally taped the seat switch and jumped the starter. Found the pulled wire when I got it back on the trailer. Just thought I would pass that one along, it might save someone some grief.
