ISO drain snake

Hello neighbors, I’m working on cleaning out a backyard drain/downspout pipe that seems to be clogged with leaves (and maybe some roots). My 15ft hand snake is getting to the issue, but only able to clear about half a leaf at a time and I need something bigger. Before I go rent one from Home Depot, I figured I’d see if anyone has a drain snake that can accommodate various cutter tips that I could borrow. Thanks in advance! Will Brown (412) 841-6285
