Would fix myself, but poor health means I can't. Simple fix for someone not worried about cosmetics. Pulley came loose at end of last season and so drive to cutting blade lost, so retired from service. Generally shoddy bodywork, and starter solonoid needs replacing, but before loss of pulley it cut and drove fine, forward and reverse.
Electrics to seat cut switch disabled, but replacement comes with. Will need at least 2/3 strong people to lift down steps from raised garden without damage to garden or tractor.
Im afraid I can't help for health reasons.
