1. Small screen, no lightbar
You can go to the mojoRTK website and see what you're dealing with. That's everything you get. You have to look at that all day long for your guidance. Fortunately for us the radio on the JD 4430 is straight in front of us and slightly up so it's not too bad. If your radio is off to the side you'll be turning your head every time you want to see how far offline you are. To be fair, if you're using autosteer, you don't have to look at it very often at all.
Another option is to use the NMEA output on the mojoRTK to send a signal to a lightbar that will accept a NMEA input. That will be good to get you in the general area but if you also want to use said lightbar to store AB lines or save the position where you left off at, know that the lightbar is only recieving WAAS signals that are not corrected for terrain. They don't advertise that one....you can currently get a free upgrade and put a code into it that makes it so the NMEA output is sending RTK and terrain correction to the lightbar as well (which we have done). We have not yet hooked a lightbar up to it to see how it works though and we're not totally sure that we will. Anyways, putting that code in will cost money in the very near future and judging by what other codes cost I'm guessing it will be measured in the range of thousands of dollars rather than hundreds of dollars.
2. Can't save AB lines
This does not mean that when you turn the unit off you lose your AB line. The AB line that you are currently using will still be in the same place the next morning when you go to finish the field as long as you either haven't moved the base station or you put it in exactly the same place that you had it the day before. However, you can not create an AB line in field one, do half of it, then go to field two, create a new AB line, finish field two and come back to field one to use the original AB line. You can of course make a pretty accurate replica of the original AB line by going back to field 1 and following your original tracks when you make the AB line but it is more cumbersome than other options.
We're thinking about trying to get around that by using the NMEA input on our EZ-Guide+ to save AB lines. We are not sure that it's worth the trouble and the extra clutter in the cab for what we're doing though. As long as we start one field and finish it, we should be fine....anyways, to utilize that NMEA input for such purposes it's imperative that you get the code that makes it so the NMEA output is RTK and terrain corrected. Like I said, who knows how much that will cost in a few months.
3. Not as portable as I'd like it to be.
We use our EZ-Guide+ with EZ-Steer on our sprayer and both of our tractors. We were hoping to be able to use the same approach with the mojoRTK and we probably could if we spent a lot of time making a holder for it and setting brackets up in each of the tractors and our sprayer. However, what we really need it for is planting and drilling and although those happen in different tractors, they also happen at totally different times of the year so we're probably just going to take the time to disconnect everything and switch it over to the new tractor when there's a rainy day in the summer.
Basically, the mojoRTK is really designed to stick in your radio slot and it seems like it will work best that way. You could get their quick change kit that has a mounting bracket and two antennas and cabling for each of your tractors but that's another $2,000 for each additional vehicle. | |
