I have a SCAG Wildcat mower, and I put the leaf collection system on today, planning on starting the leaf collecting sometime next week. The tube that runs from the blower on the deck to the hopper has a few growing holes in it from debris that gets thrown through the tube at a high rate of speed. Any ideas on how to fix the problem? It's a plastic tube spined with metal rings for rigidity roughly 9 to 10" in diameter. The dealer wants $58 for a new tube that'll end up doing the samething.
