Question for 36mtr /+ wide sprayer operators ??

[Pilatus]

How do you ever judge whether the end of the 36mtr or wider sprayer boom is not overlapping the grass margins around the edges of fields, especially when spraying glyphosate!!!
I am only asking out of interest as years ago I found it hard enough judging where the end of the sprayer boom was using 24mtrs boom

Practice, working your way up from smaller boom widths helps I found, and we run a 60cm length of rubber hose hanging down from the end of the boom which gives a visual guide on where the end of the boom actually is and the boom height out on the end although the height is controlled by the NORAC system nearly all the time. We also have all our field boundaries mapped in the JD Operations centre, so when your spraying a field if the boom does stray outside the cropped boundary it shuts the outer section off automatically.

More than likely anyone on 36m+ will be on GPS

Need some seriously good boundary’s to drive on auto steer around the headlands. It’s doable, however you have to really trust your boundary’s

 

[Feldspar]

Map your boundaries with RTK and record curved AB lines as you go. Topcon has a boundary guidance feature given a recorded boundary that automatically generates guidance paths. I can do pre-ems in the dark like this with no markers on the drill. You trust the screen more than what you can see out the window.

I certainly like the very basic but very practical idea of the 60cm length of hose on the end of the boom
Reminds me of the days before tramlines and I used to have a long length of plastic baler twine tied on the end of the (12mtr)booms, so that when you turned on the headlands,you turned slowly so that the string doubled back on itself, you then new you were in line with the last bout,all you had to do then was to drive down between the rows of whatever the crop was, without losing concentration, a lot easier said than done

Any modern sprayer should have GPS rally. It eases the workload for the operator and the accuracy and work rate will be better, too. The cost of sprayers is one thing but the value of the chemicals going through one in 5 years would make you sweat just thinking about it.

I've seen some pretty first rate sprayer gear, a modern vario tractor with GPS and isobus etc nearly makes it as good as a self propelled.

This is the only way you can do it, field boundaries mapped with RTK, autosteer the headland tramline and the auto section control set to turn off if any part of a section strays outside the boundary.

Unless the boundaries are largely straight running on gps for the headlands can be hard work. Auto steer tends to ‘react’ which creates a whipping effect on the end of a 36m boom.

If it's set up correctly it's no worse than steering manually

If shared waylines using same tractor as on drill. I just use same lines I use when drilling headlands. Your drilling off edge so it's always the same and correct.

I drill all headlands off boundary.

Agreed, at least the JD and CNH systems I have experience of the steering was very smooth and almost scary how good they were.

Did you do much spraying with autosteer?

All our spraying, fert spreading no worries

What tractor GPS is it on?

I've briefly tried when sprayer on new Holland and found as described it causes whipping
affect with booms as warksfarmer described. Fine once online.

Perhaps it's cause it's a mounted sprayer .

I’m old fashioned and use the tramlines I put in with the drill

Tell it it's a trailed implement . My brother in law had the same issue and sorted it this way .

GPS / autosteer ! will more than pay for itself in boom repairs

find it flawless tbh these days

With your Fendt do you just use existing waylines or use single contour mode mapping the whole field including tramlines as 1 line when spraying?
