KV Tellus & GeoSpread

[1996Farmer]

Hi,

I'm looking at purchasing a KV Geospread that has the Tellus Pro box with it. The current farmer is using it with a JD Starfire setup.

I would like to use the spreader for GPS on/off, rate control section control, etc.

I want to put it on older tractors, case 1056, that have nothing. So I'm assuming I need a receiver of some sort, and the correct wiring/looms to provide power to the tellus and the receiver and to allow the receiver and the tellus to talk to each other, being new to precision farming this seems a bit of a minefield and i have no idea which bits i need so any help would be much appreciated.

Thanks.

Tellus Pro screen?

So you need to feed it NMEA data, this will be done with a serial RS232 cable.

You should be able to use an Ardusimple F9P, like this:

simpleRTK2B - Basic Starter Kit

The Starter Kit allows simple and fast evaluation of Dual Band GNSS (GPS/Galileo/Glonass/Beidou) RTK technology, based on u-blox ZED-F9P module.

And this:

RS232 plugin

With Ardusimple XBee to RS232 adapter you will be able to connect your simpleRTK2B or simpleRTK2Blite GNSS RTK receivers to any RS232 hardware

A cable that plugs into the bottom of the Tellus screen:

You could put all that on any tractor even a classic Nash !! easy peasy
The Machine if it didnt have it can be supplied with all the correct loom to make your tractor isobus & connect into either KV small roof receiver for signal or patch into any other system
Ive swopped mine to diff tractors now & still prefer the spilt view of the factory Tellus Box.
Its all unlocked for everything. never go back now.
Speak too a KV dealer be your first start id say.
No reason you cant get ISOBUS loom & anything else you need.

Needs a few wires connecting and setting up.

Thanks very much, I spoke to a couple of dealers who haven't gotten back to me yet, but one indicated the KV Receiver was £1500-2000 before any wiring. This then makes an autosteer kit better value, as you get autosteer a second screen, can use it for other jobs etc, but then I'm spending 5k on top of the spreader, which hardly makes it a 'cheap' upgrade! As a newbie, the way Antenna and Receiver are used interchangeably seems very confusing.

So antennae goes on cab roof, a wire goes from antennae to receiver where the satellite signal is received and converted to a position.

You don't need to spend £5k, can do it far cheaper and in many ways better:
