Why
let your tractor drive itself?
by Kurt Lawton
GPS-guided assisted steering
- Improves accuracy (tillage, planting, spraying,
fertilization)
- Reduces fuel, seed, herbicide, fertilizer costs
- Allows daylight accuracy during night operations, at faster
speeds
- Allows the driver to focus on the implement
- Reduces driver stress, body aches and pains
If you want any of these benefits, then you should consider this
satellite-driven technology, now entering its 10th year on the market.
It's not about being lazy. It's all about making your equipment more
precise and more cost-effective...and giving yourself a break from
stress, too.

Lightbar
versus assisted steering
by Kurt Lawton
If you didn't jump on the lightbar manual-steering guidance
bandwagon early in the decade, fear not. Why?
- You can now buy assisted-steering technology for the price of an
early lightbar system.
- Or, you can still ease yourself and your wallet into GPS-based
steering accuracy by buying an improved lightbar system.
However, if you ask any farmer who has upgraded from a lightbar --
which requires you to steer -- to hands-free, assisted-steering
technology, most will tell you to jump right into assisted steering.
Some growers say it is harder to steer via lightbar than watching a
planter mark. But perhaps you're not ready to let go of the wheel
yet.

Assisted
steering and the value of RTK
by Kurt Lawton
The approximately 29 GPS (Global Positioning System) satellites
each circle the globe twice a day -- 11,000 miles overhead -- to
receive/send radio signals to GPS receivers. Six to eight of them are
directly visible to a GPS antenna at any time.
To accurately track and steer your moving tractor/sprayer/combine, your
GPS receiver needs five or more tracking channels (four are needed for
good 3-D position estimates; the other channels scan for satellites just
coming into view to replace those leaving radio range). It should have
an update rate of 5 Hz to ensure enough data are being sent, and it must
be compatible to receive your desired signal(s).

First
look at GPS-based planter controls
by Kurt Lawton
With the advent of GPS-based sprayer boom section control, such as
John Deere's Swath
Control Pro, the company is working to do the same with planters to
help farmers save seed costs.
This spring, John Deere is testing a Swath Control Pro system for
planters. "Leveraging the technology from our GreenStar 2 (GS2) Rate
Controller, we are currently developing a new system to turn planter
sections on and off according to GPS coverage," says Seth Crawford,
marketing manager, John Deere Ag Management Solutions. "This system will
work automatically to help growers minimize double planting in headland
and other areas of odd-shaped fields."

Grower
experience: Why RTK?
by Kurt Lawton
Instead of using expensive horsepower and secondary tillage tools,
southeastern Minnesota grower Steve Hafner has improved the efficiency
of his operation with strip-tillage and satellite-based technology. Why?
- Farming in strips offers huge savings in fuel and fertilizer and
time and machinery costs, along with conservation benefits.
- The precision of RTK and assisted steering improves crop production
by placing less fertilizer in perfect proximity to the seed, while
placing the seed in warmer soil.
- Assisted steering reduces driver stress and fatigue.
- The cost of assisted steering and an RTK satellite signal (complete
with his own base tower) is much less than the cost of higher-horsepower
tractors and secondary tillage on every acre.
