Have a 4-14 mounted plow I pulled behind my D-19. Was plowing sod with it and was in low all the time. Had 16.9-38's full of fluid at the time. Ordered some new shears for it and took about two years to find some. In mean time put on new rear tires and put on what the book called for 15.5-38's. No fluid and could not get traction so took one bottom off. Now a year later the new shears come in so put them on the three bottoms. Have not used this plow in ten years now so today I put the forth bottom back on and for the life of me can not find that other new shear. Looked in every corner of every shed. It has to be around here some where.
