Layout is pretty good and it's functional. Will you be adding any more content? The only thing that looks a bit off is on the links page other than that good luck with it.
I dont mind the layout as it fits well within the color scheme,and the content is good (Although needs to be double checked as i've seen some errors) but the thing that I think you need to improve on, is to get more pictures in the content section. Looking at the header gets old and I bet some of your viewers would enjoy a picture of a "green mower". In order for your site to grow you'll need to keep adding content as this website as of now Is not a website you will return to.As the information can be read quickly.But if you have a site which ranks mowers, gives information, and etc. you have a better chance of returning traffic. With the google adsense banner to make it not have the scroll bar get a brand new ad and with the code they give you adjust the width to the correct size of your template. It will cut off the Ogle in Google but that will be it and it will get rid of the scroll bar
the colour is interesting, but add more content to reduce the empty space and center the ads so don't pass the border...
