Gehl Shredder knives needed

Hello-

I am looking for some knives for an old Gehl green chopper. It is a model SA-21. This uses the same knife as the Gehl Clean-Cut model CC-60. These were the cut and throw style chopper/shredders that pre-date the modern flail choppers such as the Gehl model 72 and 7200. Made around 1960. The Gehl part number for the knife I need is R13023. Gehl number R13023-A, R13023-B, and R13023-C ARE NOT what I need, these are the J-shaped blades for the modern 72 and 7200 flail choppers. It is about 2.25" square and has a knife edge on both sides as it is reversible. I will post some pictures. If there are any old Gehl dealers in your area let me know. Have only found 6 knives so far, I need 30. Have already checked the Parts Depot, they have none. Any help would be great. Please see pictures of blade and machine below. Thanks!

-Jesse

I have the name here, Lacal Equipment, 901 W Pike St, Jackson Center, Oh 45334 937-596-6106 Look them up on the web and then give them a call. Mower knives are their bussiness and they make the aftermarket knives the dealers sell. They would have no problem with hardness.

Thanks Don and Leroy for the steel advice and Lacal lead. I will give Lacal a call on Monday.

If you have them made locally, I would have the ship make them out of something like S7 tool steel. It's very tough and holds and edge well when hardened. It's an air hardening tool steel so it's fairly easy to do with a torch.

Another option would be D2. Again, air hardening and tough.

Leroy-

Thanks for the info. If you happen to go that way ask them if they have any. Don't make a special trip. I can get these made locally, but getting them hardened is the tough part. I doubt mild steel will hold up very long.

Google yellow stone imp in Stanley wi it's like walking back into 60s 70s old style holland and gehl signs still hanging brochures from the 70s and 80s still on the wall. He still has a pile of no Allis imp parts and one corner in shop is full of gehl stuff. I make no promises but he's the first place I try and rarely leave empty handed. I'm milking now but later if you need the number I'll post it.

If I can find some decent used for would those work for time being? Neighbor has one back in wood lot only one I ever seen in person. Also has a gehl coal stove back in his old gravel pit. And your welcome sorry he wasn't able to help. When did they quit making them we had another dealer over east that started selling Sheppards and fox and gehl beutch imp pronounced beach I know up till bout 5 years ago we sourced all our hard to find fox and new idea stuff there they bought out dealers stock's of parts when they went out. Call chili imp in chili wi ask for dan omegan he used to be a sales man there while your talking to Dan they were a long time gehl dealer I believe as well. I'll keep thinking and milking and you keep calling around and sooner or later we both will get something done!

wi red dairy man-

Thanks for all the help! I wouldn't mind having used knives if they have some life left in them. Also, would like to find a few spare arms that they bolt to in case I lose or break one. See what he says about the one in the woods. Where are you located in WI? I am in Waupaca. Will also try Chili Implement. Thanks!

I have a CC60 that I no longer use for this same reason. It's really too bad, I love the way it mowed. The teeth are worn to nothing, and a few have been lost which has now thrown it out of balance. As a matter of fact, when I had a little more time this winter, I was going to lift it up and take pictures of the underside of it and post them on here and see if anyone had any ideas on retrofitting modern style flail knives on it. I by no means looked as hard as you for teeth, I just had the part number and called a few old Gehl dealers around me, they all said "no longer available, we don't have any". I also Googled the part number with no luck there either. I would really like to get my CC60 back operating again, actually totally rebuild it, as I just love it to pull behind a small tractor with no 3 PT or hydraulics. I would use it to break in fresh rebuilds on smaller tractors as it would really work them. Maybe someone else on here can help us, as this is the only flail style mower I have ever owned/used/worked on, so I really don't know a whole lot about flail teeth or the means of attaching them. I did however used to be a welder/fabricator, so any of that would be no problem.

Ross-

Thanks for the reply. I know what you mean by the power consumption. I am running mine with a Farmall 450, which is close to 55hp and it really works it good. In thick stuff I have to go in lowest gear. I think a guy could easily fabricate the blades, but you would have to get them heat treated to harden them or they would wear out very fast. Going to keep calling more Gehl dealers, maybe I will get lucky, but I doubt I will find the 30 total blades I need. If you ever part out your CC-60 let me know. 608-346-4088. Thanks!

What's the width and the distance c-to-c on the holes?

The dimensions are 2.25" wide, .25" thick, and spacing center to center on holes is 1.375". Thanks!

Former Gehl dealer down the road had none left. Checked with a guy that bought out a bunch of parts from the former Gehl dealer across the river that closed up this spring and he didn't have any either. Wonder if you could take the old ones and build the ends back up with weld and then sharpen them? Not talking about welding pieces on, that is a no-no, but just adding metal with hardface rod. should still be able to sharpen with a grinder and they should wear well. Balancing could be an issue, though.

I guess hard surfacing buildup may work. I only need to build it up about 1/4-3/8". Then regrind to a cutting edge. Thanks for checking dealers near you.

For what it's worth, this is what I wonder:

Knowing how equipment manufacturers like to recycle designs and parts, I wonder if your little blades have the same thickness and depth (distance from sharpened point to sharpened point) as Gehl chopper knives from that same period?

Would chopper knives be easier to find?

If the dimensions were the same, a metal shop might be able to cut a chopper knife into the little lengths to match the blades that you have and broach/punch the square holes.

Another option might be onlinemetal.com? A friend of mine had them make a bunch of brackets to rebuild a wagon. He had about forty little brackets cut to the proper dimension and drilled and simply shipped to him. You pay for the metal by the square inch. Drilling and such are practically free. If I remember correctly, they stock tool steel and other hardened steels that would hold an edge.

Philosophically, I think that green chop is about THE most underappreciated/utilized method of forage management. I can't count the number of times, in the last ten years of running our own little herd, that I wished that I had a working flail chopper or a machine like you have.

Good luck.
