I purchased my 790 new from the original owner in 2010. It has proven to be totally reliable and up to the task of maintaining my less than ten acre small farm. It is a no frills machine but the no frills is a plus for a small farm. I added MMM this year and the 60" MMM is perfect for the 5+ acres I finish mow.
The gear drive is a plus and it is totally reliable on a machine that only sees five hours or less per use in the summer. It was a great purchase for me and I could not be more happy.
