JD 750a question

[RTKfarm]

I'm a new and inexperienced user of the above drill and I'm having trouble closing the slot behind the coulters. I have fitted gutter wheels but wandered if there was something else I could do to help. The ground is pretty dry so sense would tell me I shouldn't be having this problem!

I'm drilling wheat and depth is about 30mm. Rear harrows are down but aren't doing a lot

 

[Clive]

assume you have full pressure on the gutler ?

it might just be too dry right now on some soils

 

[SilliamWhale]

I think its the dryness.

I run different closers but I actually use them on low pressure because it works better - if your going at speed heavier closers can bounce a bit and miss the chance to close the slot. Are you noticing any bounce? Whats your speed?

If your worried (and to be honest if it rains next week I think it will be fine anyway) run a roller across the slots at an angle.

I have the second most down pressure setting on the gutter wheels.

I am travelling about 11km and yes there is a bit of bounce. I am worried about leaving a 'motorway' for the slugs to go down. It's direct drilled after rape!

is the rape still alive ? if so they wont touch your wheat IME

I have WW after OSR crawling with them right now and am not going to use any pellets until the OPSR has gone - hopefully by then the wheat will be fine anyway

At what stage do you think the wheat has grown enougt to not be seriously damaged by slugs anymore? Im asking because I have DD'ed wheat after osr for the first time ever. Now when the wheat have reached 2 leafs and the osr is sprayed and gone, the slugs finally have moved to the wheat. It is now pelleted but will it be neded again or can the wheat stand by itself later on.

At what stage do you think the wheat has grown enough to not be seriously damaged by slugs anymore? Im asking because I have DD'ed wheat after osr for the first time ever. Now when the wheat have reached 2 leafs and the osr is sprayed and gone, the slugs finally have moved to the wheat. It is now pelleted but will it be neded again or can the wheat stand by itself later on.

its rare to loose wheat to grazing IME beyond 2/3 leaf when the plant is actively growing in warm moist conditions, at 2 leaf I would be keeping an eye on it but probably not pelleting given time of year and likely speed of growth

I probably wouldn't have pelleted if I was you but its taken me a couple years drilling on green to get that confident with it

Probably about four days after its been combined. We had a lot of grazing of the ears this year which I did not/could not treat and it left an appreciable amount of damage.

A few things can affect slot closure. Some already mentioned. Another one could be too much pressure on the disc compacting the side wall making it hard to crumble. Also try running the seed firming wheel on low pressure for the same reason as above. The other reason could be that the soil is not used to no till and does not have surface tilth. No till gets easier the longer you do it as a your soils improve. You need to shut the slot if slugs are a potential problem. Hope that helps.

 

[RTKfarm]

Thanks all, definitely a few things to try especially reducing the pressure on the coulters and closers. I was running at the end of the green scale for coulter pressure. Rolling has definitely helped closing it up

How old is the drill? Which type of openers does it have? What dia are the discs? If the discs are getting worn you may need to raise the seed boot to stop the boots forcing the slot too wide on 50 and 60 series openers. Which press wheels do you have? Slot closing is easier with the new type v shaped press wheels or Needham v8's than the old ones. If your opener pressure is on the end of the green part of the gauge it is about where I would expect it to be in hard conditions, remember if you change the pressure on the gauge it will also change the pressure on the closing wheel so you will have to adjust accordingly. Some operators don't realise that there are four positions of the closing wheel spring and don't use the highest pressure position. If it has a following harrow I would replace the standard tines which are totally useless with angled type tines that sweep loose soil over the slot.

The drill is brand new this summer so no wear at all yet.

When referring to the press wheels do you mean the little black wheel that firms the seed in the slot or the gutler wheel (I replaced the JD wheel with a gutler from Wox agri) on the back? I'm assuming the gutler on the back. Yes the rear tines do appear not to be working that well, all they seem to want to do is fall into the channel left by the openers and almost rake the seed out which is making things worse!. I have even moved them all to try and avoid this happening. Changing them to angles ones does seem like a good idea, however it would be nice to have them lifted up out the way and the slot being closed as it should be.

The trouble is I've had a lot to drill this week so I've reverted back to my Dale Eco drill where I thought I would use the JD drill as we all know rain is on the way this weekend! I think I need time to experiment with it in the field!! Or go and see someone with more experience than I have got!

The press wheel is the seed firming wheel.

The closing wheel would be the guttler.
