AgriVue Heads Up display

Smucker's LandMark II GPS guidance system now has a new wireless display unit called the AgriVue Heads Up display. The new display may be mounted on a soft hat so the farmer or tractor operator has a constant view of navigational information. The data appear in a personal display within the wearer's view. This technology frees the operator from distracting glances at a lightbar and also works well in low and bright light as well as noisy environments. The display is lightweight and compact. Pricing has not yet been set for the display.

The AgriVue display was developed through a venture between Smucker and Motion Research Corporation that integrated SportVue Pro Heads Up technology with the Hemisphere GPS system. Motion Research has developed the technology for wireless personal displays that are now used by military pilots and in motorcycle helmets.

TRC for SiteWinder

The Canadian manufacturer Terradox Corporation offers a terrain compensation package called TRC for its SiteWinder GPS guidance system. The new option ends position errors that may occur when a vehicle pitches and rolls on hilly terrain, causing the GPS antenna to swing away from the centerline of the vehicle.

The TRC is equipped with a dual-axis tilt sensor that constantly monitors terrain errors. The SiteWinder takes the information and corrects its guidance and mapping display to reduce gaps and overlaps in swaths.

The TRC-1 kit includes a TCX-1 tilt sensor, TRC software activation code and user manual. The TCX-1 is installed on the floor or other level surface inside the cab and connects to SiteWinder by one cable. Cost of the TRC option is $750. The basic SiteWinder GPS guidance system is $5,995. It includes an intuitive, on-screen, 3-D visual guidance and navigation display.

Cultiva OnTrac

AutoFarm developed Cultiva OnTrac for growers who want affordable assisted steering that is easy to install. OnTrac is installed on the steering wheel to provide hands-free driving on nearly all makes and models of tractors, sprayers, spreaders, combines or other ag vehicles. AutoFarm says the assisted steering device will deliver up to 2-in. pass-to-pass accuracy.

It takes about 30 min. to install OnTrac. The device mounts below the steering wheel with basic tools and can be quickly disengaged by gripping the wheel for manual steering.

OnTrac is controlled by the Cultiva ATC, an 8.4-in. color display with a virtual highway view of the field that lets the operator see where he is in the field and where he has been. This controller with OnTrac provides driving accuracy on contours, circles, turns and straight lines. An optional tilt compensation package may be purchased to handle vehicle tilt on hills. Other functions on the Cultiva ATC include where-applied maps and record keeping. It transfers quickly from tractor to other equipment and features a fast plug-in for installation.

The Cultiva OnTrac with ATC will retail for less than $8,500. Growers with Cultiva ATC and a compatible GPS receiver can upgrade the guidance system by purchasing OnTrac for $3,495. AutoFarm reports that the system works well in Wide Area Augmentation System (WAAS) and OmniStar HP differential correction modes.

CenterLine 220

A new low-cost GPS guidance system is now available from Midwest Technologies. CenterLine 220 is designed for growers who want a lightbar guidance system at a more affordable price, less than $1,700.

The system operates in two modes: straight line and curved AB. A large display unit shows off-track direction and distance along with swath number, ground speed, selected guidance mode and whether a return point has been stored. Another map page shows a bird's-eye view of the vehicle in the field.

CenterLine 220 installs easily and can be quickly moved from one vehicle to another, according to Mid-Tech. The compact device includes an internal WAAS-compatible GPS receiver with 5-Hz position update. A small GPS antenna mounts on the vehicle roof and connects to the unit.

For more information, contact Midwest Technologies, Dept. FIN, 2864 Old Rochester Rd., Springfield, IL 62703, 217/753-8424, visit or, or circle 203.

EZ-Steer Terrain Compensation

The capabilities of GPS guidance continue to increase. Ag Leader Technology is selling a T2 Terrain Compensation technology option for its EZ-Steer and EZ-Guide Plus systems. The T2 option will compensate for reading errors that may occur when a vehicle drives on slopes and rough terrain or when it makes a sudden heading change.

EZ-Steer is an assisted steering system with an electric motor that attaches to a vehicle's steering column. It keeps the vehicle in line without using hydraulics. EZ-Guide Plus lightbar guides the EZ-Steer system and automatically turns the steering wheel. According to Ag Leader, the systems are affordable and easy to install.

The cost of adding a T2 upgrade to an existing EZ-Steer unit is $995. The price of an EZ-Steer unit with T2 on it is $4,395. The price of an EZ-Steer without T2 is $3,495. Circle 204.

Ag Leader also has upgraded its Insight DirectCommand system to control granular applications. It will perform fixed rate and prescription map control of up to five products at once. It may be used with spinner spreaders, strip-till toolbars and air carts that use motorized servo or PWM hydraulic valves for rate control. Pricing was not available at press time for the Insight DirectCommand with granular capabilities. Circle 205.

The complete system includes the Raven 410 receiver, SmarTrax DM software and the Raven GPS enhancer. It lists for just under $16,500. Controllers, lightbars and HydraSteer hydraulic steering kits must be purchased separately.

The new system allows operators the flexibility to upgrade with just the parts needed or to purchase the entire package. For more information, contact Raven, Dept. FIN, Box 5107, Sioux Falls, SD 57117, 800/243-5435, visit or, or circle 206.
