not last monday but the monday before I was changing blades on th forty eight. Slipped with the wrench and now have 12 stiches in my nuckles on two fingers on my right hand. Don't be stupid like me were gloves, very heavy gloves. I will finally get them out this monday. Then the begining of this week I purchased Ryans mataway and 26inch walk behind aerator. The aerator is nice but the mataway works you hard. Although the mataway works you it does an awsome job so I really can't complain. I am going to use the aerator for every property, but evantaully i will get a tow behind for the large ones.
