The Power Smart PS10 Chipper Shredder is what you need for your small yard. It can mulch at a ratio of 20:1 and it is very easy to move around. It effortlessly shreds leaves and twigs. Check out my review.
The trademarked MyRIDE suspension system makes this Toro TimeCutter 75213 60-Inch Riding Mower a perfect machine for large fields with a lot of rough patches and some hilly areas. It's so powerful it cuts mowing time by half.
