Hayter Harrier 41 powered by Briggs & Stratton. Rear roller to create those all-important lines. And now no longer required.
(It was green, some of the pain had pealed so we sprayed it blue in lockdown). Cleared out the garage and found it.
It was working, but it has developed a petrol leak the area affected is shown in one of the pictures. Is good for parts or if you repair it I'm sure it will do you proud.
