The controller signals a solenoid operating a hydraulic valve on the motor to control motor speed. Extreme and sudden changes in speed cause a decrease in population and spacing accuracy. Shaft speed is adjusted by simply moving the lever on the hydraulic valve. Investor Relations Contact: of Trimble: 408-481-7838 Media Contact: of Trimble: 408-481-7808. With almost instant activation or deactivation, there is no lag time in your operation. I'll be using it for a cyclo 800 planter. This is an unreserved online only internet auction event.
The new system also eliminates the counter shaft and bearings needed for the old system. Two seed boxes mount on the rear planter bar, and one is center-mounted on the front bar. I have a Rawson Accu Rate on my 950. With the hydraulic, the meters will turn the speed they are set at regardless of ground speed. Disclaimer This Item was not Functionally Tested and no guarantees on condition or operability are made by BigIron.
Various sensors along with data entered into the monitor by the operator determines meter speed required to achieve a chosen population. The gear indicator sections fill in, one at a time based on system activity, then turn solid green to indicate at least one motor is operational. Four hydraulic cylinders are used to power the lift assist wheels. We felt we could get our money back quickly. Others have tried this without the valve.
Rows can be slid closer together since there is not a tire. Founded in 1978 and headquartered in Sunnyvale, Calif. The three boxes hold a total of about 45 bu. The Rawson hydraulic drive system is hooked up to the radar gun on the Deere monitor via a æY' cable. A refurbished Rawson hydraulic drive unit drives the original primary driveshaft through the original seed transmission. The controller allows growers to gain precision and increase yields by varying the rate of seed and fertilizer applied, both easily managed from the tractor cab. These statements involve risks and uncertainties, and actual events and results may differ materially from those described in this news release.
You almost need variable flow hydraulics on your tractor or you won't have enough hydraulics to lift your planter without turning the drives off. He could not justify new equipment. With the addition of Rawson's technology, Trimble adds to its fully-integrated solution in the flow and application control market, allowing growers to choose how to guide, monitor, control and automate their farm machinery. The original pto-powered hydraulic pump that powered the seed blowers was too small, so he replaced it with a larger pump. The manufacturing plant, assembly area and main office are located in Oelwein, Iowa. Factors that could cause or contribute to such differences include, but are not limited to, the performance of Rawson hydraulic and electronic control products and productivity gains that may be realized; continued customer satisfaction and market acceptance of Rawson products; and the ability to fully integrate Rawson products with other Trimble products and to develop innovative, end-to-end solutions for the application control market in the future.
Rawson's line of speed reducers matches engine speed to driven equipment speed, allowing both the engine and load to operate at peak efficiency. You really need the valve for 2 reasons. These types of hydraulic systems usually have large oil reservoirs and increased oil cooling capacity. Each piece will sell without reserve to the highest bidder. You need to adjust the speed of the drum, which I'm sure you know. The Rawson hydraulic drive system is hooked up to the radar gun on the Deere monitor via a æY' cable.
You should try to drive the same speed while planting. Most compact tractors have an open center hydraulic system. He could not justify new equipment. Rawson drives allow customers to vary the seed rates while Tru Count clutches allow customers to shut off individual rows. SureDrives automatically adjust meter speed on each row to keep a consistent population around turns, contours and terraces. Description Controller time delay compensates for any latency in the control system when changing between different product flow rates during variable rate application. Adjustments for planting depth and other functions are the same as on the original planters.
Catwalks allow easy access to both bars as well as to the area between them. Additional risks and uncertainties include: the risks inherent in integrating an acquisition; unanticipated expenditures, charges or assumed liabilities that may result from the acquisition; retaining key personnel; and the continuing impact of the current global credit crisis and recessionary conditions in the U. It makes for a very neat and compact drive.

It will turn the seed meters from a stop to as fast as you want to go.
