Hayter Harrier 41 Lawn Mower. I have too many mowers and have decided to sell my Hayter Harrier 41. Not only did I come away with the spring but also this mower. It has only been used a few times whilst in my ownership.It has the ultra reliable Briggs and Stratton engine, which starts with ease. It is a variable speed machine that is self propelled, with a rear roller to provide lovely stripes. It is light enough to move around those tight angles. The grass bag is in excellent condition. The new owner will not be disappointed.
