Finished converting the five bottom plow that I had asked about to a four bottom and took it out to a neighbors and plowed out a few acres of old stand alfalfa. Been 42 years since they had plowed that field. Plowed about a foot deep and plow cleaned up and plowed well. I ended up having to replace frogs with other used ones that I had and put new shins, landslides and wear pads. When I bought the plow it had good deepsuck shares and good Moldboards Sure nice to be able to buy new parts vs the older No. 8 and 10 plows with the blacksmith bottoms. Might need to replace a couple of coulter blades, anyone know the rule of thumb for when they are considered worn out? Thanks, Mike
