It's a 6' bar. I also priced a 7' bar. I use it to trim my two dams. I can cut the tops with my MX6, but then the edges just lean in. So I go the sickle to cut back the edges. The down angle helps too. The flaw in my thinking was that I don't want my wheels right on the edge of the dam. So with a 7' bar I could safely cut 6' out. As it is, I can cut 5' out which works OK, but more is always better. I also have a section by the edge of the pond, and I need to be two feet in on that so the bank won't collapse. The 2nd reason I should have got a 7' one is if I put it vertically and have it 1 foot off the ground, I could cut around my hay fields to keep the edges clean to "top of cab" height. This gets close, but still need some hand trimming. That's OK because there will always be some branch that needs to be beat back by hand. The other use I make of the cutter is to cut around the edges of the field after the farmer who cuts the hay cuts and bails the fields. 6 feet just fine for that. They are a little maintenance intensive, need full greasing every 2 hours of use. A full cutting of the fields and dams takes about that long, so it works out OK. I've also used it on some fields that have not been cut in a few years. After a careful 1st pass, I can cut to the inside of the field to make sure that nothing is over 16 inches tall, including small trees (mostly gum trees) that have popped up. Then I can MX6 rotary cut the field down without worrying about popping something on the bottom of the tractor as I ran over it.
Have hydraulic lift on it, it's nice. I also added a TNT to the tractor and an iMatch, didn't post pix 'cause that _would_ be CAUP.
