Disc Harrow ?

Matty6270

I am in ready to rip up my land for seeding. It is 11 arce of unlevel rocky ground. It was burnt off 2weeks ago. Would a disc Harrow be the best thing to go with?

For me I'd go with 2 runs of disc harrow and one of power harrow. Did it earlier this year and it worked well.

If it has a crumbler on the back disk can leave a good seed bed.
but a power harrow after does a very good job too

Was it bare when you sprayed it? Have you it eat down?
You'd want the ground fairly bare for a disk Harrow tp make a good impression on it

I got the contractor to do 2 runs with the power harrow and no Disk. I was worried since I put a good lot of dung out on it before hand but it was well fit for it. left a great job. I'd say a disc would bring up more stones

If you are using a disc make sure to travel in the same direction as you will be going with spreader, etc. as the disc can leave a lot of bumps and ridges, which don't really disappear with a leveller because the soil is very fluffy after the discs, then when it settles the ridges are still there.

Big advantage of discs is that it's fast.

We reseeded a field last yr that was ploughed the previous time it was reseeded. Full of ridges. Could go 20k now over it its that level. Went up and down and and diagonally across the fieid

why bother tilling the land at all, leave it rot for another 2 weeks
then just spread the seed with wagtail spreader at about 1.5 bags per acre
give it a roll.
it will come on as good as tilled ground with a lot less cost and soil will be a lot firmer
i do all my reseeding that way now

Going reseeding shortly. Not ploughing as stoney ground. Which would be better
A. Two runs of disc harrow and one pass with seed or
B. Two runs of power harrow and one pass with seed?

severeoversteer

if you are going to buy an implement for reseeding a powerharrow is the best yoke

you would get away with a

sprayer
power harrow
fert spreader
roller

and that's all you need

take it nice and handy with power harrow and you will have seed beed in at most 2 passes

what size power harrow could a 90hp drive?

you would drive a 3 metre harrow

most power harrows are 3m wide

I see a neighbour bought an old rotavator for hacking around some rough ground he was reseeding, probably bought it cheap enough

Its not the power to drive a power harrow scratching the surface youd want to worry about its lifting it, A 90 hp will have enough to do to lift a heavy duty harrow, deff want front lift arms and a big weight out front. also a p harrow is a minefield of trouble compared to a disc and trying to till a hard lea sod without any prior cultivation wont be long finding a weak point,

they aren't terribly complicated now either

sure take it nice and steady and he'd be fine

How does a power harrow compare to a rotovator. Similar job?

Anyone any advice or past experiences??

just do it

If the ground is level and you've it cleaned out well I wouldn't bother with either. Grass harrow, seed, gran lime, 10-10-20 followed by slurry has worked for me.

Depends on what you mean by stony. You say you are not going to plough so if there's a lot of large stones or shallow soil over rock, then you could do damage to the power-harrow.

In that instance much better off with a disc harrow as they can cope much better with stones and rocks. You may need more than two pass with the disc though.

Attach a grass / chain harrow on the back and it will help with the levelling and tilling, discs don't level the ground so well.

Power harrow much better for general tillage and reseeding type of work in my opinion. Blades work vertically, so less inclined to seal the ground than a rotovator where the blades work horizontally.

Powerharrow also has levelling bar at front and crumbler at the rear, rotovator generally does not, although you can get crumbler on a rotovator occasionally.

Rotovator generally better at tilling to a greater depth for eg potatoes & veg etc, gives a very fluffy seedbed, which almost needs to be rolled before seeding, if no crumbler.

Rotavator old technology now compared to powerharrow. How many are sold new compared to powerharrow, very little I would say.

Wouldn't do damage to the power harrow. Just don't want hassle of picking stones and ground is fairly level. Not a big fan of direct drilling. No bad experience with it just prefer to break the sod a bit

I think a powerharrow might bring up more stones than a disc. Run the disc with discs set pretty straight ad grass harrow behind. Have you much to do? Maybe try an acre with each and see which one looks best before deciding?

About 12 acres. Two diff contractors. One has disc. Other has pharrow
