Heavy harrow used to flatten standing stubble and redistribute and size flat residue. Typically used on small grain stubble resulting from yields greater than 60 bu/ac. This implement is set so the large coil tines do not dig into the soil, but rather scatter the straw between the ranks of tines. It's use to improve seed soil contact to encourage weed growth and volunteer growth 10-24-06 MAS G 01 gtdepth 25.400051 gtilint .1 gtilArea .1 gtstddepth 25.400051 gtmindepth 25.400051 gtmaxdepth 25.400051 P 01 P 02 rroughflag 1 rrough 6.096012 P 05 rdgflag 1 rdghit 0.0 rdgspac 0.0 rdgwidth 0.0 dkhit 0.0 dkspac 0.0 P 11 asdf 3.0 crif -0.22 P 12 soilos .2 P 13 laymix .1 P 31 kilflag 2 P 40 P 24 fbioflagvt 0 massflatvt1 .8 massflatvt2 .7 massflatvt3 .6 massflatvt4 .6 massflatvt5 1.0 P 25 burydist 1 massburyvt1 .035 massburyvt2 .025 massburyvt3 .02 massburyvt4 .01 massburyvt5 .02 P 26 massresurvt1 0.01 massresurvt2 0.01 massresurvt3 0.01 massresurvt4 .01 massresurvt5 0.01 P 34 frselpool 7 ratemultvt1 3.0 ratemultvt2 2.5 ratemultvt3 2.0 ratemultvt4 1.5 ratemultvt5 1.0 threshmultvt1 0.5 threshmultvt2 0.6 threshmultvt3 0.7 threshmultvt4 0.8 threshmultvt5 1.0
