750a A very different approach

[cows sh#t me to tears]

Also installed an Agtron population and blockage monitor kit. Its the isobus unit and simply installs between the seeder harness and tractor . the sensors daisy chain around the heads so as long as you number each one from your starting point it is easy to find any sensor that has an alarm of a blockage or in need of cleaning or a sensor failure.

This is one nice #pimpmydrill.

Shifted the weights from the rear of the bar to here

Should also make for a more pleasant experience greasing the rear gangs. No more weights right in the middle of your back[emoji41]

Fitted up 4 of these as well

Now I can still shut off half the drill. This I do quite regularly as our individually fenced irrigation bays arnt the right width for the seeder, and there's always a 4 foot strip left.

Below shows the hose configuration that allows each half of the bin to go to both heads . Splitters are used directly after the venturi's . The two centre hoses cross before rejoining reversed splitters which then join each tower. The shut off valves work perfectly in theory. That is to say that in the shed they do their job , with no air escaping at all when closed. I have used a wind meter to measure the speed with both heads working and then used this to set the fan speed for half shut off via the 7620's electric remotes. This way all i need to do is reduce the seeding rate by 50% on the isobus screen and reduce the hydraulics, flick the switches and away we go...

I for one are finding this fascinating. Can't wait to see it in the field. Thanks for the regular posts.
No sure about dead heading the seed with half width shut offs though.

A few others share your concerns .... I hope that i don't have any issues. I have kept the shut off valves as close as i can to the splitters and by cutting the seed rate by 50% i am hoping it just follows the air flow. I will only be engaging the valves at the end of a run whilst not seeding as i need to vary the rate and hydraulic flow. The fact that there is no loss of air through the closed valves gives me hope. Also the main times i will be using it is with grass and clover seeds, so nice and small and lite.

Edit; They'd bloody want to work for the amount of grief they gave me with the wiring up... I'm a dairy farmer not an auto elec. I had them working perfectly just sitting on the back of the drill. When the valves were installed and solenoids in it became a different story...I had all but conceded defeat and had asked the local auto elec if he could take a look , but gave it one more crack and managed to work out what was wrong.

Gday mate, what did you use to hold the weights on just some inch rod welded onto the frame?

Gday mate, what did you use to hold the weights on just some inch rod welded onto the frame?

From memory i think it was 20mm. Also a bit of 20mm gal pipe welded underneath to help tie the weights together.

 

[dano]

Thanks for that mate, nice work on the drill too.

 

[JohnBoy]

Do these drills come new with a box of cutting disks, welding rods and a few litres of green paint?

Suppose it all depends whether your happy with what they do. For me , I bought it as it was the only 6m single disc machine (that was going to be reliable) at the time. If they could sow desperate product from the factory i wouldn't have touched it. If I had my time over I would buy a 626 super seeder out of NZ. Triple boxes , bourgault single disc openers, easier calibration. On the fly adjustable down force. Interestingly the guy that builds them had a 750a prior.

626 super seeder doesn't produce a suitable result on Google!

 

[green giant]

I could be wrong but I think this is what your looking for @RTK Farmer

[RTK Farmer]

Yes thanks gg.
Looks to be a nice drill.

 

[cows sh#t me to tears]

Yep that's the one. I was living in hope that it was actually a bourgault product, as my local JD dealer is also a bourgault dealer. Then I would have asked about trading the 750. But upon further investigation I found it to be a separate company.
I also had the heads, towers and splitters sitting in the shed. So this was the cheapest way to achieve the result I was after.

That is actually where I settled on the idea of shifting my bin. Prior to seeing the 626 I had contemplated heads in front of the bin and then the heads on the wings. Both had there problems. So keeping the heads over the bar looked like giving the best outcome . the added benefits are easier servicing of gangs( no weights in your back), easier calibration ( no climbing over bar), easier emptying (again, no climbing over bar) and easier loading ( no dropping wings) now I just back up to my landing.

Agree,the super seeder is some drill. I know a guy here who moved to DD with a 6mtr 750A with 130mm rows and made 2nd tank to take fert. He got sick of it riding out of the ground and hair pinning, long story story short sold it and brought a super seeder and is over the moon with his.

Started sowing Autumn pastures today. Nothing better than sitting in an air conditioned cab on a 38°c day.....so far so good. May need a small mod to stop some seed being spat out where it shouldn't be . But apart from that, I' m rapt.
Shut off valves work. As the agtron gear alarms for 18 sensors when turned on. Happy with the extra bin capacity.

What sort of money is a 626?

All finished and ready to go.
