I have been a devoted user of the Grasshopper Mower for many years and recently replaced my trusty machine with a newer, larger model. Alas, in my excitement at the time of purchase, I failed to notice that my new model lacked the optional vertical roller corner wheel. It was only when I attempted to mow around my outbuildings that I realized the significance of this small yet indispensable roller. Without it, I found it remarkably easy to damage both the siding of my buildings and my new mower.The arrival of the roller package was a welcome relief, complete with all necessary hardware, fasteners, and clear instructions. True to Grasshopper’s reputation, it was a high-quality product, and it installed with ease. Now, my new mower navigates around obstacles flawlessly, guided by this essential addition.I highly recommend this indispensable accessory for all Grasshopper mowers.
