Drill radar

[Jellyfarm]

Drilling yesterday with our sprinter into quite thick volunteer osr, we had lower seed application than we had calibrated for. Would the taller osr affect the radar and therefore the drilling rate? If so is it possible to use one of the other speed measurements to replace it on the drill? (ie gps or tractor speed) If so how? We currently use the drill on a Deutz imonitor (inbuilt Topcon) screen using isobus.

In the extended menu you should be able to choose the speed signal source I’m using the tractor for mine and taken the radar off the drill

Ok, thanks for that. Is it likely the vol. osr is messing with the radar? Do people find this with cover crops?

Wouldn’t of thought it would ?
you didn’t notice difference in speeds on screen vs tractor speed ?
you can input speed from radar , tractor radar or gps input

I found that my co3 radar (same asSprinter?) was driven mental by tall covers like mustard and rape.Land speeds were all over the place. I moved it behind the tractor wheel and all works fine now.

Yes. Radar speed sensors are affected by tall wavy crops and also puddles of water or gaps (grates). Depending upon the manufacturer some can be worse than others.

Height doesn't really throw a radar speed signal off track, but a moving body does. If you've got the stalks brushing under the frame then yes you ought to either move the sensor or use a different speed signal. I'm not familiar with Isobus or Deutz but I'd say that you've got the easiest way if you have in-built GPS on the tractor and can select that on the settings.

Mine works perfectly by just moving the bracket across the frame so it is in line with the wheel. (thissolution was suggested to me by another co owner who had the same issue). Even tall covers are now no problem

RDS said radar reacted much faster to changes in speed than GPS, they advised me against using GPS as the speed signal on a drill for that reason. I’m not sure if that information is now out of date or not, but it’s something to consider.

That’s correct, but you’d programme a seed prime time on the control box for starting in corners etc anyway. In reality the time delay isn’t big.

Seed prime only works if the drill man remembers to press the button! Which happens to helpfully right next to the off button. When I’m on the drill I’m now much better at hitting the right button, the other chap has given up trying!

I think RDS were also concerned about changes in speed while drilling as well.

Still think the simple low tec solution might be the best?

Yes so do I!
Thankyou for the replies and ideas. Sorry for the delay, but have been away for a few days and discovered I can't post from my phone for some reason!
