The operating mechanisms are simple and operate smooth and fast. Notice that nothing protrudes out past the deck to minimize accidental damage. To order a custom fit unit we need a picture of your actual mower deck discharge opening the model number of your tractor and the dimension sketch sheet filled in and sent back. Please ask any questions about the information we require from the sketch sheet if not sure. Most residential lawn tractors and zero turn mower decks will use the same mounting bolts as the original discharge chute.Commercial installation could need 2 holes drilled. (Mounting hardware included) No more bungee cords, no more blowing off hard surfaces, no more picking out grass clippings from your mulch beds and no more SH-T. Please inquire with all your questions and we will have your order to you about a week after we receive your specifications. Note: FREE installation for local orders in our shop.
