Plow, disk, drag (spring tooth harrow) was the typical order of operation for seedbed prep. Today it is rare to see a moldboard plow, chisel plows are still in use around here followed by a soil finisher which is one piece of equipment which contains multiple harrow components, disk couler, spring tines, sweeps, rolling baskets, spike tooth harrows. Then if you start talking about vertical tillage, some of that combines the whole plow, disk, drag, with one piece of equipment. Minimal till or no till doesn’t move the soil around, no breaking up or leveling required. <br></div><div data-signatureblock="true"><div><br></div><div><br></div><div><br></div></div><div style="padding-top: 5px; border-top-color: rgb(229, 229, 229); border-top-width: 1px; border-top-style: solid;"><div><font face=" 'Calibri', 'Segoe UI', 'Meiryo', 'Microsoft YaHei UI', 'Microsoft JhengHei UI', 'Malgun Gothic', 'sans-serif'" style='line-height: 15pt; letter-spacing: 0.02em; font-family: "Calibri", "Segoe UI", "Meiryo", "Microsoft YaHei UI", "Microsoft JhengHei UI", "Malgun Gothic", "sans-serif"; font-size: 12pt;'><b>From:</b> <a href="mailto:jtchall@nc.rr.com" target="_parent">John Hall</a><br><b>Sent:</b> Monday, May 4, 2020 11:25 PM<br><b>To:</b> <a href="mailto:at@lists.antique-tractor.com" target="_parent">Antique Tractor Email Discussion Group</a></font></div></div><div><br></div><div dir=""><div id="readingPaneBodyContent">For you "older" guys, why did you run spring tooth harrows? What <br>implement replaced/obsoleted them? I've got one, haven't used it in 20 <br>years. Not sure it ever did anything but burn fuel. When I was a <br>teenager we would run a section harrow behind the offset disc harrow if <br>we were trying to break up clods, level furrows, knock the dirt off <br>roots, etc. Just wondering what good a spring tooth harrow was/is. Yes I <br>know it will choke up in trashy ground, and pull hard if you set the <br>teeth way down.<br><br>John Hall<br>_______________________________________________<br>AT mailing list<br>AT@lists.antique-tractor.com<br>http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com<br></div></div></div>
