Had the county doze some trees out along county road and fix road ditch last fall. Pushed brush to north end of field. Decided to plow it this spring. Had not been plowed in ten years anyway. Took the D-19 and mounted plow to plow the eight acres. Had a acre to go and hit a rock and broke a point off one of them new shears. It took me about five month to find new shears for this plow and now I broke one. At my age it may be the last time I use this plow any way. Park the 19 for now. Next morning get the 450 Farmall out and the 311 (think) plow to finish the last acre. When done painted the plow shears on both plows and take them off. Went in to lunch come out to hook up swather to mow hay and 19 has a rear tire flat. Set there all night and drove it around yard today and now it has a flat tire. No hay is getting mowed today.
