    Thought it would be useful to gain some knowledge from other weaving GD users out there to share experiences / problems / solutions.

    I'll start.....anyone else had problems with blocked coulters? I've had a lot. It's been on the wetter side of ideal, but still good drilling conditions. It's got drier, and I've still had issues of rape stalks blocking the coulter tubes. Anyone else found this? When it's wetter than ideal the solution would be a redesign and put the coulter tube in front of the bearing, rather than behind it, but that won't happen in a hurry. Just wondered if there was anything else to try, or just not be so impatient?!

    Had a demo yesterday and went fine into tall rape stubble. Not quite sure how it could block really. How fast were you going and how deep?

    10-12 kph 50mm deep. The coulter tube is split for the last 3" of length, supposedly so if something does get in the end, seed can still get out. But I'm not sure the split doesn't enable more debris to be able to block. Certainly when it's moist, soil can get behind the scrapers and build up and then pack into the split in the coulter tube, blocking it.
    But I was amazed that 5 times I managed to drive over a rape stalk at exactly the right angle and size to go up the coulter tube and block it!

    Check the disc touch each other when the meet. If not there is a spacer washer behind each disc, take it out and it will tighten the discs.

    Weaving were recommending speed of about 9 kph and we were drilling at about 30 mm but sandy clay so completely different conditions really.

    DD ground was where I had more problem with wet soil blocking, moved ground (2" min till) is where I had stalk issues. Having said all that, a day of sunshine and I haven't had any problems, so I'm guessing it was just too wet really

    The operators manual suggest speeds 8-15kph are normal. Certainly higher speeds are possible in moved ground compared to DD

    Problems with a GD- our other operator has had problems getting the 8m trailed machine in the ground or staying in the ground,in a DD situation of a hard crust and moist soil below the tine drill has no issues also side hills of anything just shed it crabbing which isn't going to look pretty when it comes up.anyone else found the same.

    yes regards the crabbing, I have backed the pressure off slightly and let the wheels bite a. It more. Not perfect but. Better.

    As regards penetrating hard ground no problem. But ours is only 6 meter

    thanks for that.i said we need weaving to come out and see what is going on but I'm not the driver did think it was strange it wouldn't go in as it was only a crust on top.

    Mine crabs a bit on side hills, surely any trailed machine will? The GPS seemed to account well for it though and the bouts were matching up fine. What exactly was the problem with the crabbing? Just bout matching? As to penetration, I've had no issues with my 4.8m. Is the hopper bigger on your 8m? I'd imagine you need double the weight of a 4m to achieve same pressure? When I drilled some cover crops early on after wheat it was very dry, but if you have the "down" switch set so the flotation tyres are completely clear of the ground it put it in no problem.

    I'm not the operator so only getting info secondhand,but the crabbing agreed any trailed machine will my co8 does but not to the extent the GD is 18" on a slight hill the co doesn't even notice.the hopper is a 4t fert/seed so weight shouldn't be a problem,I have been surprised that the drill hasn't performed as I hoped.drilling speed is a lot slower than I would of hoped at only 9k when the co is knocking along at 12k.as we have moved into zerotil I keep being told one drill can't cope with all situations but we keep going back to the old co,
     
  14. Have had one blockage here, put it down to soil on the inside of the disc and a badly adjusted scraper.

    Was putting too much weight on the caddy wheels so coulters behind the tractor wheels were not penetrating as well, initially we ran the 3 behind each wheel deeper but with a bit more weight transfer we put them the same as the others. Will look at wider tyres on the drill tractor next year, maybe 800's on the back.

    Drilled all tilled land at 10 km/h and no till at 8 km/h. Was after low disturbance in both scenarios, tried 12 and too much soil movement.

    Need to reconsolidate tilled land more. Press on the front of the drill tractor or press/roll after cultivator.

    Have tried a 5 leg, 3m low disturbance cultivator on one field. It has sumo grassland legs in it and a toothed packer. Will see how that looks in the spring. Looks initially like low disturbance requires low forward speed.

    Not happy with using it in chopped straw. Have only drilled mustard cover in this scenario but lots of hairpinning and uneven germination. Better results with our amazone cayena. With that in mind maybe a sabre tine tool bar would work on the caddy.

    Using case puma 180 CVX on the front of our 4.8. Handles it very easily. Had no ballast weight on board.

    We have drilled 900 acres so far and not 1 blockage that we have noticed. But we do check the discs weekly and tighten any which aren't touching

    I drilled my 2nd wheat DD yesterday. I've had no blockages in tilled land- it's been very dry and cobbly. Had another 3 blockages on the 2nd wheat land into chopped straw. Blockages were only straw, no soil! I'm not convinced the long slit in the coulter isn't actually creating the problem. More likely to get straw riding up between the discs and the coulter tubes, and because the coulter tube is slit, it can then block it. If it only had a hole at the bottom of the tube, I'm not sure it would block as frequently, but presumably weaving designed it like that for a reason!
    I did as Willy suggested and shimmed a few up which had gaps, but, perhaps I need to keep a more frequent eye on this. Apart from that, I was really pleased at how well it coped with the chopped straw. It did go in very deep, possibly too deep, but I was afraid of hair pinning, so set it deeper. I think I've learned that I can set the depth shallower, but pile on the pressure using the weight in the hopper to ensure it cuts through chopped straw. Couldn't do this with OSR and linseed as not enough weight of seed in the hopper!

    again I would say if the pinch point is tight, no straw can get between it, so take some more spacers out.

    Also we are drilling at 8.5 kph and find this to be the best overall speed.

    Had a demo Early Aug. 14ha. Cover crop into Pea debris. Crop came pretty good in the warm soil. Plenty of biomass! It cut through thick patches of Mayweed well and crop grew through it. Handled the sandy hilltops better than the subsequent Sumo DD (bulldozed the sand). Quick for a 3m drill - 7ac/hour.
    Didnt Roll it given the presence of a Press-Wheel. Do others Roll after the GD??
    Need to try it in heavier less kind conditions before I buy

    I reckon you'll find it works better than most other drill on heavy land in the wet

    What have you done to the soil pre-drilling? How does it cope with flat-lifted heavy versus non-tilled stubble?
    And do you think it definitely needs rolls despite the press-wheel?
