Several versions of those are running around. They do add length and for some attachments it's not a problem, for others it can be. You'll just have to work around them.
I don't know what brand those are so I can't speak to what I've heard on quality.
Tuff brand. Probably china.
Was thinking about building a set, but im guessing 8-10 hours, time better spent earning money or doing yardwork with tractor.the way weather is going, times running short.
I like it just because my implements are different widths, better than nothing. As stated it does at length but i havent ran into a problem. Combined with Hodges stabilizers, hooking up is a breeze
