Ez boom on trimble 750

Anyone running a trimble 750 plus ez boom through a delta 34 controller. Going onto a househam air ride

Think you can go to a max 8 sections. Does the system work well for auto shutoff.

Thanks

This couple won't work to my knowledge. You will need field iq or an older display if you already have ez boom

Ez Boom doesn't work with a 750 as @manttys says.
You need a Field-IQ to go with the 750, or a an Ez Guide 500 to go with the Ez-Boom.
I used an EzBoom with a RDS 34i for a season and it worked well.

Apologies, I meant the Trimble field IQ system with a 750 box using a delta 34 controller.

What's the max number of auto sections you can control through a delta 34 controller?

If you have 750 box + field iq, you actually no longer need a controller, trimble can do this altogether with section control. It starts with 12 sections and can go up to 48. If it is trailed sprayer, I would keep original controller only if switching tractors. Well, this is what I saw on the internet, please correct me if I am wrong.

Max sections on a RDS 34i was i think 9. If you want more than that you need to go pressure control only on it.
The Field IQ doesn't do pressure control but would work fine on flow control then you can get rid of a control box out the cab.

are you saying you can't adjust pressure with field iq, that is, you cant adjust droplet size? Maybe there is another way to do it, pressure level should be visible on the screen. So how then the system defines default pressure?

It is simple maths, not a question about the controller brand. At a given tank mix ratio (litres per hectare) and a given nozzle size, you have to drive at the correct speed to get the correct pressure and droplet size. At a given speed you would end up to the same pressure independently of the control approach (flow or pressure). Select your parameters correctly and you get the wanted pressure at the planned speed.

The Field IQ is flow based so it measures the flow going to the booms. In order to set the rate the controller need to know how many nozzles that flow is going through
So on a 24m sprayer the controller aims for 48 l/min through the flow meter at 12kph give 100 l/Ha.
If you switch half the sprayer boom of it needs 24 l/min through the flow meter for the same rate. The screen doesn't need to know the pressure or size of nozzle but it does need to know the how much of the boom is active (and forward speed).
If you run a pressure based system the controller need to know the nozzle size and the pressure but not how much of the boom is active or how many l/min are going to the boom (and forward speed).
Not the best explanation but all I have time for I'm afraid

So am I correct, that you see pressure level just for indicating purposes. For example, if aim for 48 l/min at 12 kph and the pressure is too high for the nozzles (let's say 5 bar instead of aimed 3 bar), you have got low debit nozzles or you have to drive slower.

Don't want to create separate topic... Does anyone know if it is possible to combine boom control valves and separate electric nozle holders into one system with field iq. I would like to have 7 sections + 4 separate electric nozzles. There are always a small overlap when drilling, so the might be actual 23-23.5 meters instead of 24 meters when i have 24 meters tramlines. Individual nozzles at the end of the booms would allow me saving 2-4 percent of the chemicals and avoid damage when spraying liquid fertilizer.

The Field IQ doesn't really care what does the switching on or off of the nozzle it just puts out a 12v/0v signal and you can do what you like with it.
I can't remember what current is a safe current to draw for each section but if you want you can wire the Field IQ to switch relays if you need more current that the Field IQ can give.

Do you know if 12 v if when opening or closing? I am drawing schematics what I am going to need. I would guess I will need normally open nozzles/section control valves.
Any experience with the electric nozzles? Cant find too many of them online..
I would additionally need dickey john flow meter and dickey john flow regulator. Am I missing something?

It's +12V and common ground for sections on field-iq (and old ez-boom). I would definitely use relays for solenoids taking something like 1A per unit.

You can set the individual section widths freely -> individual nozzles should be ok.

Last spring as i refurbished my old manual sections sprayer for field-iq / ez-boom I bought 3 wire section valves. Their control wire only takes some 20 mA.

I also built a DPDT relay box for a neighbor for a Hardi. Hardi 2 wire motor driven section valves need the polarity (+/-) to be flipped for opening/closing the 6 sections.
(There is a small motor + 2 limit switches in each valve.)
The master valve relay is "commanded" by diodes.
Built it with a Hardi type din connector to directly replace the Hardi controller.

Interesting projects keep you younger;-)

I would think that you could use almost any brand valves & sensors. I used italian Tecomec.
http://www.tecomec.com/line/geoline/index.htm
as I happen to have an excellent dealer almost next door.

The good thing in my old sprayer refurbishment was that using only one brand (arrag type tecomec) all parts in the valve block (valves, filter and flow meter) fit together with no pain at all.

May I ask why are you trying to cope with the issue instead of getting rid of the issue? I mean why do you drive the sprayer with RTK but not the drill? I assume you have RTK for the sprayer, otherwise sections for individual nozzles would not work.

You make a point, but the problem is, that fm750-ez pilot kit is on 110 hp all rounder on a mixed farm. It will be doing loads of stuff where I can use ez pilot. Although it will be towing sprayer. The other tractor is for drilling, bale making and plowing, grain carting. There is no easy way of flipping the system from one to the other one. I could buy another ez pilot in the future and use one display for both tractors, but today is how it is.

I will be using RTX range point, dealer promised about 10 cm from pass to pass, so I recon I could make use of single nozzles at the boom ends..

Does anybody on this forum know what make flow meters come from trimble? I was promised dickey john but received Italian gear. The dealer told me they just make orders and don't know what make it comes. I don't buy it. Paid 500 euros for the kit while the same manufacturer is 275 euros on web shops. Thanks for your imput
