replacement discs

WTA · Jan 4, 2008

I have an old krause 10 foot wide double offset disc and it's time to start replacing the discs on it. The front ones are worn 6 inches shorter than the rear. It has been taking multiple passes down the field to do anything so I need to start rebuilding it and save some gas.

I found some grizzly brand 20 inch discs at tractor supply and was wondering if they are any good. I've never heard of them before. I was also wondering what style is best to get. Notched or plain. I think the fronts on this one used to be notched but they are so worn it's hard to tell.

What is the difference in the two and what would be best for this hard West Texas soil?

the notched disks are your "cutters" and the smooth or just plain round disks are your "finishers". in my neck of the woods we would use the notched disk harrow 1st to break up everything and mix the soil. then b4 seeding run a smooth disk harrow through, sometimes w/ a piece of metal pipe or wooden pole chained off the back to try to get a nice seed bed. some models have the "cutters" on the 1st gang in front followed by "finishers" on the rear gang. you may want to run the cutters on front for the hard soil, or even add some weight to your disk if your tractor can handle it. good luck w/ the rebuild and also be sure to get a few cans of pb blaster for getting the nuts lose if that disk was out in any weather.

Disc blades can vary in thickness. Look carefully at the gauge. Thickness equals resistance to breakage as well as longer life due to wear.

Notched blades do cut a little better, but at a price. Less metal equals faster wear and increased likelyhood of breaking. Under NORMAL conditions the difference is minimal though.

MOST disc blades are "generics" from companies like Herschel, ect. Unless you're going to be discing hundreds of acres on a regular basis, these generic blades will last many years.

This thing has been outside for a LONG time. No telling how old it is but it's not new for sure.
I'm not worried at all about power anymore. This thing used to be pulled around by an old MM 4 star but that one died on me last fall for good and I got a new tractor. It's a NH TD95D 4x4 with plenty of power. I could probably pull three of these at once if I wanted to now. I thought about upgrading to a bigger disc but I can't really afford it and I'd also have to replace all my gates if I got a bigger one. I'm tired of digging post holes.

Thanks for the replies. I guess I'll get the notched cutters for it.
They were 30something a piece and 7 gauge thickness I think from TSC. That doesn't sound too bad. Right now I have an old flywheel on the back of it from an oil rig that weighs about 400 pounds and 2 front end tractor weights on the front weighing about 200 pounds. I'm going to do something better with that set up too. It definitly needs more weight.

have you tried agrisupply.com? I have bought some from them and have had pretty good luck except for two that broke in half about a month of use. called them and told them what happened and they sent me two replacements for free! Great customer service and the best price I found anywhere,almost 1/2 the price of tractor supply.

You might be surprised if you put your 10' disc up for sale. All these guys looking for equipment for food plots have been driving prices up like crazy. Around here a 10' disc is a high demand item since it is very hard to buy a new one under 12' 6". I wanted a 8' disc to pull behind the TN at times when the ground is too soft for my 10 or 12' and found one that needed work. But my friend begged me every day till I sold it to him. He wanted a 8-10' disc and I wouldn't sell my 10' model. Another friend wants to buy my 10' disc and has been begging me for it. I know when I had it parked in my side yard for a couple days I had plenty of people knocking on the door asking about it. I had to stop parking equipment in the side yard as people keep thinking it is for sale

I do need to pull the 10' into the shop and rebuild all 4 gangs. They are not in bad shape but need new blades and one gang needs a few new parts. I figure rebuild one this year and the other next year. Then I will have two "new" disc that I shouldn't have to worry about for a while.

You will want to replace the bearings on your disc also while you have it apart. Or at the very least have them handy just in case yours are in rough shape when you pull it apart.

Anyway, if you do think about putting your 10' disc up for sale you might get enough money to upgrade discs to a larger size (12' or 14').

My neighbor has a big 16 foot disc just sitting in his field because several of the bearings are gone in it. I might be able to buy it cheap. Or trade him. His needs all the discs replaced too but it's still cheaper than a new implement.

Right now he uses mine all the time anyway.

Do you get any soft wet areas? I know I have been stuck with my 7710-II which is the same basic size and power as the TD95D but mine is just 2wd. My ground holds moisture too good and at times I fill find wet spots and if I am going fast enough I will usually make it but if the 12' disc sinks then

If your area is gravel or well drained then you should be fine with the 16' disc. It would just cost you a few dollars more in blades to rebuild that one.

What brand/model is his disc?

I think my neighbors is a krause also. That's what my 10 foot is. I wish we could hold water on our soil here. I gave up trying to dig a pond because most of it doesn't hold water very long. We only have one spot that does and it's about 3 acres. The reason I can't build a pond there is because it's the corner of my bermuda pasture. I put way too much fertilizer out there every year for fish to be able to survive. The rest of the place is easy though. We can get 3 inches of rain one day and be ready to plow the next. We actually wait for rain before plowing just to break up the hardpan.

I thought the fertilizer would help the fish grow
