john deere 750a

[hedge hog]

i had contractor drill some wheat over last 2 days with 2020 750a drill to see results on are land before buying one.
on the light land its closed the slot and done good job.
but on heavy land slots are open and seed showing
whats the best thing to do ?
tried cambridge rolling on angle which worked a bit
driver said it will wash in and be ok. drill didnt have following harrow as he said they are useless.
any advice appreciated.

Try a Weaving GD next time

Appreciate it doesn’t help the current situation, but I had the same issue. Also found it smeared the slot at the bottom and didn’t help root development.

Was the land cultivated, if so the following harrow can do a bit of good, but into undisturbed land they are useless.

If conditions are good a roll at as near to 90 degrees to angle of drilling can help close the slots, preferably using rollers with a set of paddles with them lowered down.

If this isn’t going to be possible the contractor should have stopped drilling, you can get away with it in spring sometimes, but not so easily in late autumn.

The best use for a Straw rake but you will end up with wheelings I would suggest

The more i’ve seen of it over the years the consistent solution on heaby land is the cross slot coulter

trouble is it’s neither cheap or low power requirement

to fix your immediate issue try a straw rake

Maybe a sledgehammer to crack a nut, cultipress with tines removed at same direction as drilling.

Is that really the answer though? I see on twitter plenty of people who used to post lots of photos of their CS drills, which have been substituted for modified Horschs in the last couple of seasons. Obviously too wet is too wet for a disc opener but I recall at the first Groundswell, the CS struggled to cover the seed in moderately damp conditions. I really like the inverted T coulter but can't help feel it is more reliable on the end of a pigtail than on a vertical disc.

not just cross slot coulters though is it ? the last 2 seasons have bern extreme and very few drills have coped well with that even varderstads have been useless in extreme wet but does that suddenly mean after decades of proving success they no good ?

of course not !

a simple, lightweight tine is the best option when extreme wet but although thats forefront of our minds right now its (hopefully) not the normal

in note normal years, coulter pressure, slot closure, ability to deal with covercrops and consolidation are all very important in direct drills - most tine drills do not excel at that in my experience

if weather continues to have these extreme years a lightweight Co or sabre tine certainly does seem like sensible insurance however !
