First photo is what I started with. 9' Western truck plow. ($150)
5/16" QA plate was around $130.
2nd is on the plow and snow blower on the tractor.
Been using this for setup for years now. Works good.
My plate is 3/8". Picked the plate up at auction for around $125 and bought the plow for around $200. Made the mounting boxes from 1/4" angle stock. D ring came from Harbor Freight.
