The sweeper wheels are carried on the trailing end of a parallel bar linkage attached to a tool bar by which the planter is pulled. As a result of the parallel bar linkage, the sweeper wheels may float upwardly and downwardly independently of the planter frame in order to conform to uneven ground. A spring acts on the parallel bar linkage and may be adjusted either to press the wheels downwardly into the ground if the mulch is hard and dense or to urge the wheels upwardly and relieve some of the weight of the wheels from the ground if the mulch is loose and the underlying soil is relatively fine.

RaoufatAuthor affilication: Department of Farm Machinery Engineering, College of Agriculture, Shiraz University, Shiraz, IranSerial title: Soil & Tillage ResearchAbbreviated serial title: Soil Tillage ResearchVolume: 98 Issue: 1Issue date：2 October 2007Publication year: January 2008Pages：P 27-34Language: EnglishISSN: 0378-4754CODEN: MCSIDRPublisher: ElsevierAbstract: Poor corn (Zea mays) stand establishment in the presence of surface plant residue in conservation tillage may reduce yield potential and thus limits the adoption of the method by farmers. A study was conducted to compare the effects of three tillage systems and three types of planter attachment on the amount of surface and subsurface residues after planting, emergence rate index, seed spacing indices and seeding depth of corn in a soil covered with previous wheat (Triticum aestivum) residues. Tillage treatments were single pass of disc harrow, three passes of disc harrow, and single pass of disc harrow followed by chisel plowing. Corn was planted with a planter equipped with either a plain rolling coulter, a row cleaner or a combination of row cleaner followed by plain rolling coulter. Tillage treatments did not show any significant effect on measured variables except seeding depth. Seeding depth was highest and the most uniform for the planter prepared with three passes of disc harrow. No interaction on measured variables was observed among treatments incorporating tillage modes and planter attachments. Row cleaner and row cleaner followed by rolling coulter retained less surface residue as compared to coulter attachment. Row cleaner retained less subsurface residue as compared to row cleaner followed by rolling coulter. Lower surface and subsurface residues in the case of row cleaner attachment treatment led to the highest emergence rate index. Coulter attachment increased quality of feed index as compared to planter with no attachment. Row cleaner increased the quality of feed index and decreased miss and precision indices. Row cleaner followed by rolling coulter had highest quality of feed index and lowest values of miss and precision indices;
