So...I currently have a 2 cycle Toro Proline and a Honda powered Proline. They both suffered the same fate, a bad tranny, I'm sure its just some stripped gears and probably end links. Engines still going strong. I took both of them into the shop when they went a year or two ago and the estimates were about 600 a piece...Decided to buy a new lawnmower instead, but I figure parts are only about half of that or less, I could do it myself on a couple of rainy days.They have been sitting and I'm tired of how heavy my new Honda mowers are and how bad of tracks they leave in muddy grass. Does anyone know any advice I might need before tearing into the cases?
