Lawn mower john deere JX75 21 +

Have decided that we no longer need to be a two-lawn mower family! 21", petrol, self-propelled, 5 gears, runs well, except that one gear does not work - the self-propelled function still works. Has just been over-hauled - blades cleaned and sharpened etc. Cuts grass well - can try in our garden - have plenty of grass! Can possibly help with delivery
