750 Operator's course

[Clive]

Thanks Clive for showing us the light last month and your time, money in the post!!! (though did think you had fallen over and banged your head when i saw" pimp my drill part 2")

Regards Big Al

Part 2 is mostly about additional capacity without spending big money - if you have 2 drills it would be daft for them to be the same I think ? If I had one drill without a doubt it would still be the 750

Have you seen the guttler weigths on @Bob lincs JD750? I think i've seen a picture of them here on TFF.

we have been running with weights on the guttlers for 7 years , it's not a new idea . Who knows in another 7 years someone may do something really radical like fit a set of spoked gauge wheels !!

Or perhaps replace the small rear wheels to something better for the headlands...

 

[Clive]

Fantastic day. Just need to work an inexpensive way to add some weight to the guttler.
Standard closing wheel 7.3kg & guttler 5.3kg.
How much to add, just 2kg to bring up to standard weight or more?

There is a very simple way to to this I think I found this week - better still it involves buying no parts at all !

Will experiment this spring and post about it if it works !

Omg your a genius

Joking aside , we all seem to be modifying our drills , some things work some things don't but the reason we are doing it is because we are not
happy with the standard machine and think it could be improved . Why are JD not developing the drill their selves . Vad and horsch aren't still pumping out the same machine they were 20 years ago !

I think they are doing

I would expect a replacement within the next 2 years

 

[Bob lincs]

They have been saying that for years .

I was talking to a reasonably high up JD employee at cereals and asked him when were they going to update the 750a and he told me it will stay as it is as there's nothing wrong with it .

A nice German man told me differently ;-)

We all know there isn't a LOT wrong with the basic design so I wouldn't expect a radical redesign but we all know there are options that some of us feel improves the drill they "could" offer

Did he work for KV

Will pm you !

Went to the 750A course with Simon Chiles today. Very imformative. Sure I've done the right thing in ordering one.

 

[Bob lincs]

I don't think it's quite that easy, I have a design on the drawing board in my head and just working on the calculations to ascertain the weight. Hopefully have a solution soon.

I haven't done this with my weights as I've only just thought of it while reading this , but if a tube like what my weights are inside of had holes drilled along its length for a bolt to go thought the weight could be positioned any where . Closer to the pivot less weight or closer to the guttlers for more weight . You could make it variable then rather than how I have done it by just adding more weights .

 

[Farmer.sa]

Have made up 2 discs to bolt into the guttler out of flat plate each weighing 2.7kg works really well more weight for heavy land an less for light! Not to long to fit if you have an air gun!! Will post a pic when I get a chance

Why are JD not developing the drill their selves . Vad and horsch aren't still pumping out the same machine they were 20 years ago !

They have, it's just the changes were subtle. They have gone through three series of openers, the opener spring was modified to have some free float in it to enable the drill to work in cultivated seed beds. The Gauge wheel has more bolts in it now and is half plastic to grip the central bearing better. The RID tyres had their cleaning lip reduced from 11mm to 7mm to make them last much longer ( loosing the lip is not much of a problem now). They increased the hardness of the disc which has improved wear rates dramatically. The press wheel has gone from a wide one to a v shaped one to help improve slot closure. The closing wheel spring has had about 4 versions, the last type design has reduced it becoming coil bound and therefore increased their life. The seed boot has had three versions, the latest one sits further back in the shadow of the disc and reduces side wall compaction of the slot as well as having better wear rates. The press wheel bearings have been improved and last much longer than the original ones.
Coupled with all the above the frames have been strengthened where the old ones used to crack and the metering unit software has had several versions, the latest version being capable of VR.
I'd freely admit that you have to be a bit of a nurd to appreciate all the mods but I think it's testament to the original design that the changes were actually only slight and that the other manufactures are now making drills that copy it as close as they dare without infringing patents ( the problem with that is they still haven't got some of the finer points that actually make a difference ).

Thank you Simon for running a very informative day, also to Hedley for hosting and your wife for providing lunch, chocolate brownie didn't make it to farm gate! Wished I had attended before taking delivery but now I have had a seasons experience of a 750a understand where I went wrong with setting up and should be able to get better performance in the future. Always good to put faces to fellow TFF'ers, hope you all got home safely.

Told you not to be shy of the brownies!!! Have to second you, should have gone on the course before using the drill, realy pulled all the elements together thank you Simon.

 

[Timbo1080]

Just like to say a huge thanks too, to both Simon and Hedley for a brilliant course - it's really set clear my mind on both the physical use & capabilities of the drill, and the cultural elements that need to be considered with zero til. A very informative, clear and exciting course indeed....well worth the new engine that is needed for my car, having just about limped to my nearest pub on the return journey, whereupon it snuffed it. Thanks for all your time and effort, and all the food & drink kept Nic & I warm on the cold journey home (keeping the windows open to try & stop the windscreen fogging up....it was utterly Baltic!). Great to meet and place faces to fellow TFFers too....I'll definitely pop over to the TFF stand wherever I next go!

Ive been to Simons place 3 times in my life and ive never ever been given a brownie..

That's where you have gone wrong, you need to head over to Mr & Mrs Jacksons
