Re-Designing the Lawn Mower

Hello Users,

My name is Daniel Wilkinson, I am a current third year student studying BA (Hons) Product Design at Teesside University. I have just started my final project of the year in which I plan to re-design the walk behind lawn mower found in many homes around the world. 

I would be very grateful if anyone could list me a number of problems they have with current lawn mowers, new features that you would like in a new mower, how much you would be willing to spend on a lawn mower and anything else that you think I should include in my re-design.

Thank you!
