I am in the process of converting an old Meyers ST78 truck plow to SSQA hitch for use on my L3901 and LA525 loader. I am trying to decide on exactly what type of A frame attachment to use. I have researched plows from a number of leading suppliers including Buyers, Boss, Western, Meyers, Land Pride, and Virnig. They all have different setups but they all fall into three basic designs:
- Meyers went the easy route and they simply pin their Classic mount to an SSQA adapter plate (see picture below). My main objection to that design is it puts the plow way out in front of the tractor. It does however let the plow float just like a frame mounted truck plow.
- Land Pride uses a rigid A frame weldment that brings the plow in tighter to the adapter plate. Now the plow acts more like a bucket and you have to let the loader float the blade. Not sure how well that works in practice.
- Most of the others go high tech using a rigid A frame like #2 but with an oscillating king pin attachment to the adapter plate. This lets the plow rotate along the vertical plane of the SSQA plate to follow any camber on the road surface and it also brings the plow in tighter to the tractor. But it also requires the use of loader to float the blade. I am also concerned about wear on that king pin becoming a maintenance issue.
I would like to hear pros/cons and actual user experience from people that own and/or use plows with any of these designs. I am leaning towards the oscillating design primarily because I can get the plow in tighter to the adapter plate. If the king pin fails to hold up in service I can simply revert to version #2 by welding the A frame push plate to the SSQA adapter plate
