—Lancaster Farming, Saturday, February 4,1978 1 114 Subsoiling and planting combined WILSON, N.C. - Lely of Wilson is introducing a concept that enables the grower to “rip’ or subsoil in the row and at the same tune to spray, till, incorporate and plant. It is still recommended to conduct primary tillage in the Spring or Fall although in some instances farmers have gone with the complete rig behind harvester and planted com. Subsoihng under the row is mainly popular because it allows roots to reach deeper to more moisture which is important, especially during stress periods in the Sum mer. It has been found that subsoiling in the row during the same trip as planting is the most effective way in many soils with hardpan trouble. University studies concluded that 75 per cent of compaction reoccurs during the first trip after subsoihng. This makes npper-bedder arrangements in a separate pass before planting less attractive. Lely is the first company to offer a complete system that is close con nected to the tractor. It consists of the f olllwing; 1. The Rownpper with up to six parabolic shanks which cause greater soil shattering with less hor sepower requirement. The unique shank design whereby the pivot point is positioned in front of the frame bar enables the shank to lift virtually immediately when it strikes an obstacle and to not break away to the rear first This in turn makes close coupling nf an im plement such as the Lely- Roterra possible. Row spacmg is adjustable on some models Shanks are 1 L inch thick, clearance from the bottom of frame to shank tip is 26 inches. 2 The Lely-Roterra will level the soil, reduce clods and prepare an ideal seenoed in a single trip 3 Chemicals are applied through the unique Lely system whereby the sprayboom is mounted behind the Lely-Roterra and chemicals are sprayed forward into the whirling tines after the soil has been leveled and the clods par tially reduced. This method provides excellent wind protection and ideal mixing of chemicals to precise depths. 4 Because of the close coupling of the whole combination and the depths control roller, lift assist wheels are not required and, for example, unit planters can be attached directly to the combination. The alternative would be to use the unique Lely Bridge Hitch with quick attach hook-up to the tractor which will enable the farmer to either opeiate the planter alone or the combmation of Rowripper, Lely-Roterra. Spray System, or the whole combmation. 5. Lely also offers the complete spray system, including tanks, pumps, and controls. The unique Lely Spray Command control system warns the operator in the cab when a nozzle is not performing properly, enables him to electrically increase or decrease the output and also enables the operator to cut off and start automatically the spray when the combination is raised and lowered at the turn row. The system has been tested intensively during the past two growing seasons. It is ideal for farmers who care about maximum produc tivity. It can be operated at good field speed of 4 to 6 miles per hour. By com bining five or more trips, the grower greatly increases his total output per acre in a production time unit such as a day in comparison to wider implements in single passes. The Rip-Stip System is mainly suitable for soils with compaction problems. In case of acreage with and without compaction problems, the shanks can be easily raised where ripping under the row is not necessary. A bedder at tachment can easily be placed behind the Rownpper in case some farmers wish to rip and bed. This one-trip method of preparing and planting crease yield while keeping field operations costs the soil is thought to be one way farmers can in- down. When considering hor sepower requirement it is advised to have 150 hor sepower available for four row units and up to 200 for six row units. This depends upon soil circumstances, etc. Although this may seem high, it should be considered that five trips are combined in one and that at 4 to 6 miles per hour, the total capacity far exceeds that of the total combination of individual trips by other implements. With the RIP-STIP System the grower has greater flexibility because what he has done during a given day does not have to be redone as is the case often when heavy rain occurs after discing, etc. The risk of not in corporating chemicals soon enough is totally eliminated, as well. A 20 per cent crop difference was even ob served in one test supervised by a county agent. Lely specializes in systemized farming, therefore, it is able to offer high capacity, well matched systems. If the farmer has the tractor and the planter, Lely has the rest available and will warrant it. Many the components or com- through its authorized patents have been granted binations. Lely is conducting dealers with the complete and others are pending on field demonstrations Lely ßip-StipSystem.
