Dual laser receivers. Hydraulic power source is a Prince HC7-A PTO pump. I removed the Yuchai dozer blade, and the push bar mates up perfectly with the skid steer quick attach plate. Three 5/8″ grade 8 bolts lock it in place. It works great. More pics and details on the Yuchai Face Book page. https://www.facebook.com/yuchaidozer?ref=hl&ref_type=bookmark
