Westwood T1600 Ride On Mower

I m selling my ride on mower. It has served me well over the last few years. Unfortunately it seems to have developed a drive problem as I finished cutting my lawn and will only travel forward slowly. Everything else works fine. I have only recently purchased a diesel Countax so I have no desire to spend time and money repairing it so it is being sold as spares or repair. Any questions contact. Dougie
