Vintage Hayter 21 Rough Cut Ride On Petrol Lawnmower

Very rare with seat, selling for my dad. Has had a new aluminium checker plate deck made, been painted with smoothrite paint. Comes with a 5HP Briggs amp amp Stratton engine, starts, runs and drives well, it may need a new rubber belt as drive seems to lack a bit of power up hills or on very long grass (belt maybe slipping) viewing recommend
