I see these for sale videos a lot, my problem with every single one of them is no contact info and no price posted. These videos are posted so they can be embedded in a sale page for the item being sold, but that makes them no less frustrating when you find one.
Your lawn mower won't accept all the implements a real tractor will. That is the point of a tractor vs a lawn mower and most lawn mowers are just that, lawn mowers. If you notice, this is field mowing and your light duty lawn mower will choke on field mowing and field type grass. This mower will chew through 20" high field grass if needed. Your lawn mower engine will choke out and die. The tractor can mow, plow snow, grade your driveway, have a log splitter attachment hooked to it and split wood and many other things a lawn mower can't even begin to do. A real tractor such as this is a "system" it does many things and that is it's true worth.
