I have completed my PA1, going on to to PA2 self funded, need advice! What is the correct way to spray around a telegraph pole? Any other tips or pointers welcome.

Start drilling on the post where possible so tramlines match up with the post

with gps switch extra gores not too much problem
alternatively drive up to post Back up them fold drive past unfold then back up
Not got GPS. Will I have a miss either side of the post?

Because I'm a bit bored and quite handy with Paint on the PC I just knocked up these:

1. Ideally you want to drill a field so that any telegraph poles might be exactly between 2 tramlines then you can just brush the telegraph pole gently with the breakback sections of the sprayer boom as you go past. In reality unless you have a long straight row of multiple poles the field will be drilled with the longest/straightest edge and the pole will end up wherever within the system of tramlines.

2. If you end up with a pole in the way of a tramline I tend to do a full circle around the pole, not folding up and the GPS on the sprayer sorts it out, bit more tricky if turning sections on and off by eye but still do-able and saves the hassle of folding up the booms.

3. More often then not a pole ends up somewhere like the below picture, if you stop, fold up the boom, drive past the pole and then unfold and carry on you will miss an area like the one shown in purple when you come back down the next tramline, so when I'm spraying I use the circle method like in picture 2 above unless the miss is only about 1-2m or less and not worth the hassle of driving a full circle round the pole.

Easier to explain with pics than just writing an essay on it (y)

Err, we just circle around poles, or trees, or other obstacles . . .
Wether it was back in the day of foam markers ( how crap were they, in hindsight ), CTF / tramlines or full on auto steer & section control . . .
Just circle around it, don’t bother folding booms or reversing up or anything like that

it’s hardly rocket science 🤣

Once you get the hang of the machine your on you’ll find different ways of doing it. A pole just on the ends drive up to the pole almost touching and raising as you reach it, spray drift will spray onto the 14” that you can’t get to. Reverse back, fold up as much as you need, drive passed, unfold, reverse back as close as you dare and then start spraying 1m off the crop and lowering back to 50cm as you proceed forwards. If it’s a pole tight to the machine then a full fold is often necessary, frustrating with triple folds as it’s a lot slower and worse if your on bed work as you have no option, early in the season (before the crop is 12” high you can drive around instead of folding up but I’d still spray up to the pole and reverse back to it or you get huge under laps and overlaps where the boom is travelling really fast at the ends and not moving on the inner side. Once a crop goes over 12” high I’d always fold if I had to as the crop is less likely to bounce back up. Depends how neat you want your fields to be. Worst I’ve done is 17 folds in 15 acre plus a 4 acre square wood in the middle and on a serious bank too.

Drive up to pole at a good speed. Brake hard and switch off spray just before you hit it. The spray will keep drifting forward and cover the bit round the post well enough for most jobs. Back up. Fold up mindful of the overhead cables. Drive past pole, unfold, back up, set off again.
Go back with a knapsack in mid May and hand spray or rogue anything you might have missed.

Do you seriously spray the it with a knapsack? Guess black grass you might.

the other solution is to put the strip in Efa, but in reality they are not that much of a hassle in cereal.

I used to spray for my neighbour with and old 12 Alman trailed sprayer. He had big pylons used to spray through them 10 m wide went slowly booms folded back as I crept through
Did he manage to combine in them too? That is bloody shrewd then.
I worked for someone who would go out when I was drilling a field and put 3-4 handfuls of seed around every pole. You could never risk cutting -6” with a 25ft header so no idea why he would, be there for ages when cutting taking minut pieces off each time, if it had been left a foot it would’ve been so much quicker with the combine

Do you spray going backwards into corners . too make sure you get it all , especially blight spray spuds and used to have a 45 degree nozzle to catch the long creeping tops of cara round outside

Shouldn't be spraying at all, (y) should be left for ' Regeneration' (y)

Then you get the poles with the guy wires where there's a change in direction of the line. The double poles with a transformer all of which never line up with the tramlines. As for combining round them when drilled right up, that can be a pain, years ago a farm I worked on we would liberally dose round them with simazine at least you could see what you were doing

Yes I go round the poles with a knapsack if I get time. Nothing looks worse than a pole with a tuft of rubbish round it especially into autumn. We have a lot of guy wires as well so the knapsack is often the only way of getting it all. Makes it easier for the combine as well to have a clean edge. I don’t drill super close to the poles either.

I tend to drive upto a pole and if outside section is going to hit it,stop fold outer sections 90degrees back, drive past pole fold out then reverse back to pole
if it’s going to hit inner boom section drive upto pole,then reverse and drive round boom and then back upto pole
hope this makes sense
