I purchased a Scott's Edgeguard Mini Broadcast spreader this year for seeding my lawn. I am planning to to use it to spread salt/ice melt this winter too. I'm am concerned about the plastic wheels sliding on the ice and/or snow. One of the wheels are connected to the piece that spins and spreads whatever is in the hopper. Therefore when that wheel moves, that spreader piece spins. Has anyone made any modifications to the wheels to give it better treads and grip?
