Fendt section control.

Both of our 724's are Profi Plus but neither have a Section Control icon or toggle in the Varioterminal.
I'm assuming then I need to purchase an unlock or software install?

Funny how in the manual it just covers it off as if they leave the factory ready to go.
I know John Deere is an unlock and so too is the Amatron GPS switch.

Will do.
I'm not sure how much benefit we will get from Section Control on our ZA-V as although it is a Profis Tronic it's not a Hydro drive so I'm guessing we will get auto on /off at the headland and probably half width turning on/off as we come in and out of covered ground.

Peter, how mechanically is the section control achieved ?
Looking at it i cant see how shutting off one of the 4 sections either left or right on the terminal will have any effect on the distance the fert is thrown as there appears to be no mechanical change to the vanes.
Or is it simply a rate reduction?
Amazone literature suggests unless I have the Hydro version section control will have a lessened effect.

Firstly when it comes to "section" control on a spreader you can't think of it as the same as a sprayer. With a sprayer you get 100% of your dose rate in one pass where with a spreader you don't. With a spreader you need overlap to get your total dose rate. If you think of three tramlines and you run up the middle one crudely you will have 100% of your dose rate behind the tractor, 50% of the dose rate between the tramlines and nothing at the other tramlines. You therefore need the subsequent passes up the other tramlines to get 100% of your dose rate.

So when it comes to your short work as you run into your headland tramline you still need to be overlapping to get your desired dose rate.

The ZA-V does this by reducing its rate. It will still be spreading full width. The key is the spread pattern. You want a nice flat triangle. With rate reduction you are still spreading full width but you have flattened out you triangle further still and this is what stops the over dosing.

A sister magazine to Profi in Germany compared the ZA-V to the pto drive ZA-TS and the ZA-TS Hydro. What it showed was upto around 27m there was little to no difference in the effectiveness of the section control between the V and hydro TS. When they got over 30m then the TS spreaders started out performing the V and when it got to 36m the hydro TS started to give a better result than the pto drive TS.

When it comes to section control on a spreader they all start off using rate reduction as this has the biggest effect.

Bit long but hope that helped.

Very informative and clear explanation Peter.
I must admit I was thinking more along the lines of a sectional control as used on sprayers but this makes perfect sense when described as you have.
Thank you for taking the time to post. (y)
