My John Deere 750a replacement

[Clive]

I agree the rubber sausage isn’t as complex as the jd coil spring arrangement but that might be a good thing re wear - lot less puns and bushes

 

[Clive]

Clive, how much downward flex is there in the wings?

A folding system like what the horsch uses does offer a lot of options. Nice lift at the headlands too.

No experience of it yet - doesn’t deliver until June and won’t get use until August - the wings have a support wheel to help with flex

There are compromises to be made and the steel spring based coulter down pressure system on the 750 is not as good as a hydraulic system on the cross slot. The pressure changes over the travel of the coulter. Indeed there are some instances where the spring has been replaced with a hydraulic cylinder albeit rare. As far as I can see the rubber sausage suspension compounds these issues and has more scope for early wear. The set up gives more potential for coulter sideways travel whereas on the 750 by the time you get to that point (years later) you can turn the pins round. Just my opinion of course.

Have not seen vaddys to suffer with that problem, same idea really? ?

Well, you can buy two 12m horschs for the same price as one 6m cross slot, new rubber sausages are cheap compared to running a CS

If they weren’t up to the job Horsch wouldn’t have used them. You can have up to 350kg of Coulter pressure on them!

That said, vaddys are nearly always going into cultivated land. They haven’t as much resistance on them compared to a zero till drill cutting into uncultivated ground.

I demo'd a 6 meter Avatar a year ago, we were drilling into a stony-ish paddock and I was happy with the results for penetration. If the soil is so dry that you cant get a suitable seed depth then in all honesty its probably not time to drill (maybe invest in a rock breaker on a digger & start chipping at the concrete).

Admittedly having a 12 meter drill will mean that clive can cover the ground faster when conditions come right, but then that's relative to the area needing drilling.

Currently I'm looking at a 3 meter disc drill to take the crap work off the 4 meter JD, with the aim to go wider next time we replace the JD. I think 12 meters is a bit out of my league though!

Although nothing to do with a direct drill thread we changed to a 6 M rapid last year @Clive , everyone told us that there was no way our 200 hoss tractor would pull it ,,,,,,, no problem what so ever , she flew , even banged beans in at 3 1/2 inches albeit at 12 kph instead of cereals at 14 kph . I would certainly try your 240 hoss tractor first and if it falls short then you have to have a rethink , maybe hire something for a month

like a 6mtr 750a

This spring I use our new Avatar 4.16 SD. Wery happy with springcrops compare to dirtflippers crops. Also the quality is great this far. I drill 30ha a day om my own . Possible to drill more if needed. I use a JD6170 , it is a bit overkill !

I would have thought a 6 m vaddy with it's 80 odd discs and leveling board in full work mode would take a lot more pulling than a 750 a

A fendt 724 was over kill on a 6m 750a really I bet we could have got away with 180 ish hp especially if we didn’t have the extra weight of the fert tank and hopper extension

 

[Fish]

Yer, weights the killer, we pull our 4m 750 with a 516, run about 1550rpm, 8-10kph, easy peasy, but moving the drill about with a full hopper that little tractor knows that drill is there.

We used to pull a 9m Dale with a jd 6930 - it copped fine but knew about it if you filled seed and fert hoppers on a decent bank

 

[Al R]

How about hydraulic driven axles like on potato harvesters and I’m sure massive slurry tankers and forage wagons have them?

Meanwhile, down under with our unfair advantages.....

 

[Acke]

How many hectar to drill a year ?

What sort of terrain are you on Clive? We have tried the 6m Avatar and our 6215R are maxed out at 6kph on the steeper going. Not sure if 12m would go on our 7310R!!

Its only 25% more draught.
