Hayter Harrier 41 Autodrive Mower

This mower is about 30 years old and has been in our family since new which I think was around 1987. It is fully working and leaves a good cut with stripes as it is the Autodrive self propelled machine. The reason I am listing it as not working is because there is a crack on the head which is from the pull-start over the years . I have shown pictures of this .  I want £50.00 which must be cash on collection within 48hours of purchase
