Well the straddle style captures your three point arm on each side where and you slide a pin through the arm. The cantilever style has the pin bolted to the cutter and you slide the lift arm on the pin. I find the straddle style easier to hook up and by all rights it is stronger. However...I've never had a problem with bush hogs set up as far as being weak. I looked at both of these cutters but ended up with a 172 Rhino mainly because I've always wanted to try a Rhino product.
