Computrol I ®
The Computrol I ® Planter Drive is designed to put seed population control at your fingetips. Plant too little seed, and you sacrifice yield. Plant too much, and you waste money.
Set your population rate and let the hydraulic population drive automatically maintain that rate. You have instant access to target rates, population count, total area and speed.
You can program the Computrol I ® for five different rates. For example, 17,000 and 30,600 seeds per acre. You can vary the rate for spot treating areas such as sandy acres where you may want to apply less seed, insecticide and or fertilizer.
There is no more guesswork when calibrating your insecticide rate. If you apply too little, you risk poor insect control: too much, and it costs you profit dollars. You save on seed and other inputs such as fertilizer and insecticide, thereby raising a more profitable crop. With the Computrol I ®, you can do all your maintenance, check calibration of seed, fertilizer, insecticides and herbicides right in your shop during the off-season. This prevents major in-season down time and improves bottom line profits. |
Computrol II ®
With today's high cost of seed, fertilizer and chemicals, it makes sense to continuously monitor your planter. Big John programmable monitors are designed to add precision accuracy to your planting process. Modern planters, properly adjusted, do a good job of planting, but there are times when row units do not place the seed where you may want. The problem has been that, until now, you had no idea when a row unit was malfunctioning until after the crops come up.
Sprayer Control System. The Computrol II ® does more than any other automatic spray control system on the market today. Simply set your application rate, whether you are using liquid fertilizer or herbicides, and it automatically maintains that rate on every acre regardless of vehicle speed or terrain. Programmable valves and the fast response time makes this system your best choice. With this system, you have instant read-out of target rate,applied rate, field acres, total acres, field gallons, total gallons and speed. You can program in five different rates and, with a push of a button, you can select any one of the five. This system is capable of precise application from low to high rates.
The Computrol II ® also controls your anhydrous ammonia application. Anhydrous is very difficult to apply because of temperature changes, vehicle speed and tank preasure. All three factors influence the amount of NH3 you can apply per acre. The Computrol II ®, coupled with an NH3 kit can solve these problems. |

Big John GPS Fleet Manager
The Big John GPS Fleet Manager is a compact Global Positioning System. With the fleet manager it is easy to see where a fleet of one or even hundreds of vehicles have been over a recorded amount of time. The fleet manager records where, when, and how long a vehicle is at a location and special use time. The fleet manager has a parallel port to download to a laptop without removing the remote unit from the vehicle. All files may be imported and are easily imported into mapping software such as MapInfo. |
Big John Seed Meter Test Stand
If your customers want to precision plant then they need to have their seed meters tested with precision, exactness and accuracy. The Computrol ® (with the Big John Seed Meter Test stand) advances seed metering to a new level of accuracy, efficiency, and value. If you are going to test seed meters, then why not use the best, the Computrol ® / Big John Seed Meter test Stand. |

The Big John Profiler
The Profiler is additional computer technology in the Computrol ® for analyzing seed spacing and establishing a database for precision seed placement. The Profiler has been developed for test stands and planters to be used in research/test plots on the farm. This precision seed placement technology, used with the Computrol's ® downloading and GPS capability makes the Computrol ® one of the most exciting tools in precision farming for researchers, seed technicians, producers, etc. |
