![]() Chains or gears both do exceptional jobs of transferring horsepower from tractor to earth. The tiller drive system is another option to consider and is a matter of preference. The reverse rotation brings rocks to the surface and significant damage from rocks being pulled under the hood can occur. In rocky soil, however, reverse-till units are not recommended. In most cases, a reverse-till model leaves a more desirable seedbed, depositing weeds, residue and larger clods below the surface and finely tilled soil on top. Reverse-till models are well equipped for small farming operations. Typical moldboard plows are one to four bottom, requiring about 15 hp per bottom. Some models feature a coulter in front of each share to slice the soil prior to being rolled. Plows are simple tools that consist of a curved moldboard or bottom that rolls the soil, a replaceable share point that cuts the soil and a replaceable landside to keep the plow tracking parallel to the unplowed land. The moldboard plow turns or inverts the soil and buries weeds and crop residue deep beneath the surface, providing organic material to enrich the soil. Today the moldboard plow has changed for the better - better steel and replaceable parts - but the purpose of the modern plow remains the same: to turn and break up soil, bury residue and control weeds. According to the Columbia Electronic Encyclopedia, the first patent for a moldboard plow was issued to Jethro Wood in 1814 with patent improvements in 1819. Moldboard plows have been around for literally hundreds of years. ![]() In organic farms, weed control without the use of harmful herbicides is a primary goal with soil prep. Preparing the soil can be a multi-step process depending on your soil condition, soil type and what your overall goal is. Soil Prep with Primary Tillage Implements ![]()
