750a A very different approach

Those of you that run a 6m 750a will appreciate how confusing the screen layout can be in relation to the box. Having the box at the rear has simplified this no end! The picture of the drill on the VT shows the drill from behind. This is exactly the same orientation that i now have . If you look at the drill on the screen, the left hand side box is the same as mine from behind, All i had to do was change the bin level sensor wires around in the box and now they too, reflect the correct side of the bin. Now there is no guessing which side of the bin is low or which drive i need to turn off. Also the lowering of the sensors has eliminated the annoying early alarms. When it goes off now i have about 2 runs left before its empty. Before , you could go for ages ignoring the alarms and inevitably run out...As far as i'm concerned, this is how the drill should come from the factory

All finished and ready to go.

How wide is it in transport mode?

 

[cows sh#t me to tears]

Exactly the same as before. Bin is no wider than the width of the wings when folded.

Stick some cameras in the hoppers.

I was looking at your pictures without noticing your location, and thought that looks like here (Australia).
I am near Finley, where are you.

You have made a great job of that looks just the job, am just fitting guttlers to my new six meter and kverneland ts tines on the back for now as a start, not as ambitious as you or clive, but give it a year and it may be a different story, good luck

Regards

I've got cameras sitting in the ute. Just waiting on some extra leads to turn up[emoji106]

Do you have issues closing the slot with the standard closing wheels? The gutlers are nearly a "must have fit" mod in the UK.

Doesn't really affect me with sowing grass and clover, and our sowing conditions are a lot drier than you guys. I will see how it goes sowing some barley this season. It is something i will monitor for the future. I just wanted to get the basics right and then work on the fine tweakages

This included fitting up 2 3/4 inch needham gauge wheels with urethane tires. I had at least half my oem tires fail after 2 seasons. Also have their heavier seed boot springs and bushing kits to fit up over winter.

Had to do some fine adjusting today First lot of grass has been irrigated and is now up. unfortunately it seems thicker on one side of the machine. The venturi and first splitter are joined with a short section of hose that i had to "train" into a bend in order to get the lines to the centre, due to the wings being in the way. This seems to be forcing the seed to one side of the bend and then favoring one side of the splitter.
I have 2 splitters with adjustable baffles in them , so tried that and whilst it improved it a bit , it still wasn't close enough. So today , i cut the mount of one venturi and tuned it to remove the bend. Ran some more calibration tests with bags over the 3" lines and now have it to with in 4 grams difference in a 2.5 kg sample.

Off season servicing coming to an end. So far rotated the pins on the top of the openers. Replaced all closing wheel washers and nuts (as seen in 3rd picture) and pins. Took off all the quadrants and swapped them left to right, and replaced all gauge wheel adjuster handles. Also took the opportunity to build up the damaged bushes whilst the rams were out. And been working on this for a while too

Grease banks with a grease line to gauge wheel axle and both the closing and press wheel.

Should make life easier. Had to tap all the axle holes as they aren't quite right even from new.(have you ever noticed that you can't get the grease nipple out of an old gauge wheel axle into a new one??had to use a 1/4unf tap in a pair of vice grips to tap them all in place, with a dash of crc lubricant to flush any swarfs out)...used 90° swivel fittings with push in feral rather than olives this way its easy to get the pipe out without having to replace stuff.
Now just waiting on rams to come back from engineers.


Edit: also moved the 2 centre openers on both front and back apart slightly. 7 mm each side on back and about 12 mm each side front. This was to allow standard axles to go through hubs so the grease nipple is facing rearwards . Also put the cover plates in like the other openers to protect grease lines and fittings.

Are they just pneumatic fittings and pipe used for the remote greasing?

 

[SilliamWhale]

Wow. I only grease my pivot pins about twice a year. Once in the spring and once in the autumn. Not a nice job crawling under but only a few minutes really (3m though!).

Discs are a pain to grease though but every 50 acres seems to be more than enough. To wonder about using something a bit thicker than Morris ep2 here though.

No. Absolutely under no circumstances use air line and air fittings
I got the idea from an old school mate who fitted some up to his 1590 box drill. He did use air fittings and air line. He now has to use a special (and rather expensive) grease ,as normal grease requires too much pressure and if he pumps to hard the air line ruptures and blows holes.
Air line and fittings are only rated to around 200 psi where as this stuff http://www.remotegreaselines.com/6mm-Push-in-Fittiing-System.html is rated to nearly 1300 psi. The tube has a wall thickness of 1.5mm, so it has a small id of the actual tube. The fittings are double feral (to handle the pressure)as opposed to single in airline fittingsI use Castrol LMX heavy duty grease, and had no trouble pumping it in.(I did at the start, as i hadn't pushed hard enough on the pipe into the fittings on the gangs due to the limited space, and when i tried greasing the first one it came out the back of the fitting)

Got my rams back . They took a bit of liberty over what I asked of them...And as a result I had to do some re engineering of my wing bump stops

These will get a brace across the front now to stop any potential spreading under the weight of the wings. Also had new pins made up 20mm shorter as the front ones could have caught on the frame for the wing locking point.

Happy with how they tackled the rear of the ram. They had too get a special wire in to weld the ends together as the end of the ram is cast and the new piece is machined from 4130 high tensile, as are the new pins. They also put off the shelf brass bushes in all the ends which helps with having a grease track in the middle now.

The other ends resemble the end of a howitza barrel IMO.....they thought there wasn't much point machining them down ...I guess they're right as it would have added a fair bit to the bill, just to make them look pretty....they work fine, which is the main thing. And are easy to grease with the wings folded( no different to greasing the wing pivot points). So hopefully.... That is the end of that saga.....

So, bit of an update on the fix for the rams/wings.Just went and knocked a couple of roll pins out and had a peek behind the washers. No wear at allcouple of shots of grease every few days when you grease the wing pivot points and all is good. Probably done 750/800ac since the change.

Took myself off to BPR the other day after Collin rang to say these are now available

At least twice (if not more) as thick as the OEM ones . Not quite the same level of adjustment. 10mm increments over 6mm on originals. The reason being these go with them.

Solid all the way across as opposed to the silly little lugs that wear quite easy. Also got 2 of these to try

 

[marco]

How much are the slides each?

 

[cows sh#t me to tears]

Think they're both $35au. In tractor ATM so will have to confirm later.

edit; Confirmed. $35 for both the cover plate and the handles.
