I am mowing part time. About 8 to 10 hrs. per. week. I am interested in purchasing a ZTR. All the lawns are residential. The mower has to get through a 36" gate. It also has to have a bag. The walker looks great ( out of my price range). The Fast Track by Hustler looks like a good mower, but they will not recommend it for even light commercial. The smallest commercial Hustler offers has a 44" deck. I have not seen anything else. Any recommendations for me?
