Looking for a new Heavy Harrow

I was looking at an Elmers super 7 , but have heard many of these harrows break there half inch tines on a regular basis, Is this true and for the zero till guys what harrow is tried tested, and true for the farm. I am thinking of buying the summers 84 heavy harrows. any draw backs with that one.

Oatking I have been running Elmer's super-7 harrows for probably 10 years now. I think I have owned 4 sets over that period, always traded because I had a dealer that gave me a fair trade price and had a market for lightly used ones. Current unit is 3 or 4 years old now, all have been 90'. I think I have replaced about 20-25 tines in that time, almost all on the front row and probably half on the one machine(possible a weaker batch of tines). I think the one I have now has three broken tines that I should replace, have not touched it since new. I harrow at 14mph and have rocks, hills and drainage ditches. I personally think it's the rocks that break the tines. 

They are a really good harrow. I usually run minimal down-pressure and it's the volume of tines that does the work, with the minimal down-pressure it leaves the stubble intact and stops lumps from forming. I previously owned a Summers 84 like you mention as well as Bourgault 7200, Degelman, and a Delmar. I've also used Brandt and Morris. Nothing comes close to the Elmer's for straw management and if you want to do dirt leveling just apply more pressure. Obviously Bourgault now copied the design and Summers has an 8 bar unit now, imitation is the sincerest form of flattery. 

If I had one complaint it would be with the 90' if you go through a ditch the middle of the wing can dump some straw. I often apply more pressure in those spots so the middle sections can flex lower, or if really deep I harrow along them. Some pics of the job it does. Wheat field was harrowed in spring and still spread straw around without knocking stubble down, and I zero-tilled peas into there.

How does the elmers super 7 work on soybean stubble. Some of my neighbours use the bourgault heavy harrow and it makes beaver dams all over the field. almost better to leave the field alone than. Hoping to demo a elmers 90 foot next week before I buy, Talked to elmers directly and they said after 2017 they changed tine manufacturing companies and since than the 2018 to present models have had less tine breakage. They also said they did research on thicker tines and found that the half inch tines flex more and give better straw management.

Any body try the summers 8 row mid harrow model. Summers is about 7000 dollars more than a elmers but based on my summers 2510 diamond disc they are built very well.

Any body try a MORRIS harrow or a riteway heavy harrow. I heard riteway has no cables so you can backup the unit if desired.
