Amco Offset Disc

[bindian]

Anybody have one of these in their barn or laying in their backyard? My disc is missing one. A co worker told me I won't find one and that I will have to make it out of a trailer axle cut off and welded to a plate. I also need two hubs. I'm gonna start looking at trailer parts.

One last question before I go to bed. How would Y'all fix this hitch? Bare in mind it pivots on the tongue. The egg shaped hole is about 1/4 inch from the edge. Should I just weld plates above and below it? My drawbar pin is pretty long.

you are on the right path now...
i know of a welding and metal fabrication shop in temple...awesome what they can do in little time at very reasonable prices. if it were mine, down here, i'd take it to them and say "fix it".

i'd look for such a shop in your area...not just a welder, but a place with hydraulic punches, shears, drills, etc.

best wishes...when all fixed up, it will be like new and be problem free for years!

If I were fixing it for long term use, I would do the double whammy to it. I would weld up those slotted holes and then scab on another plate on top and bottom to have at least double the plate thickness that is there now. Then it should hold for a life time (disc lifetime that is).
As for the right or left turn, I knew it was only good to turn one direction, but it having been over 50 years since I have seen an offset disc, I just didn't remember which way I used to go. The CRS syndrome is catching up fast.

I bought a 7/8 inch bolt for the wore out 3/4 "slot" and bought a 1 1/8 inch bolt for the wore out 1 inch "slot".
I had a 7/8 inch drill bit and managed to drill out that hole with my cordless 18v Makita.

I bought a 1 1/8 inch drill bit for $51. I couldn't use it to drill out the "slot". So I got out a 1 inch diameter cylinder rotary file and with my high speed pneumatic router, carefully ground out the 1 inch slot into a 1 1/8 inch hole. So for now, I wasted $51 bucks. But may use that bit in the future. Who knows?

Anyway, the Cylinder mount is bolted in place with the aid of a 4 foot cheater pipe.

I then took the complete transport wheel assembly off, as it will go to the machine/welding shop to have a 1.5 inch long slot welded up or have a bushing installed to take it back to a 1 inch hole for the cylinder's aft mount. I had to hold it up by a chain with my loader bucket while we removed the 10 inch long one inch diameter bolts with that above mentioned 4 foot cheater pipe!

The 2 existing stub axles and hubs will have to be replaced. The Amco dealer in Nome, Texas wants over $350 per wheel for wheel, hub, bearings, and axle stub. I can buy a complete NEW trailer axle and hubs, with bearings for $190. That would need to be times 2. The axles will have to be cut down and welded to a 3/4 mounting plate.

So $380 or so plus welding new axle stubs to the mounting plates is way better than $1400. Add in $240 for new rims and I am still better off than buying new from the dealer. No wonder farmers are the McGuyver's of the tractor and implement world!

I got the hole for the cylinder welded up last week and picked it up this week.

I painted it last night and installed it today. I have been in correspondance with an Amco dealer with no help penning down the model number. It took involving an Amco repersentative to figure out the disc is a WOF8, WOF9, or WOF10. He said most parts are out of stock and production. It sure is handy to have a backhoe as a shop crane to lift the rockshaft into position. That thing was almost too heavy for my son and I to move by hand!


But............I had bought new axle stubs, bearings, and hubs from a trailer supply. My local welding shop welded them to new 3/4 inch plates and had them ready for pickup yesterday. I painted them last night and installed them today, adding the hubs and bearings this evening and getting tires back on it to move it outside to wash off and paint in a few weeks.


I was able to screw the rodend on the cylinder out 1/4 inch. That, with the welded hole and bigger diameter mounting bolts did the trick in getting the hydraulics to raise the disc enough to pin the wheels down. Now it is outside to prep for painting.

Brandi,
Looks like you are coming along great with the project. Reminds me that I have alot to do this year too. Gotta get busy.

Jenkinsph,
Thanks. What have you got going on, project wise, in 2013?

Brandi,
I am getting into laser guided leveling with machine control. Basically trying to increase my footprint for custom tractor work in areas with ditch irrigated lands. Seems to be more work laying in pipe and reducing the amount of open ditches. All in all it is a living.

After the rains today, I removed the hitch from the tongue. As you can see, it is dire need for some TLC. The tongue end "box" section is drooping.

The lower forward weld looks sick and needs attention.

The hitch hole is elongated. I think the welding shop will not want to repair this, just make a new one.

As you can see it is really a simple assembly.
hugs, Brandi

Jenkinsph,
Sounds like you are in rice or crawdad country.

I think I would weld up the hole and run a reamer through it if it were me. Quick fix.

I live in Ruidoso New Mexico this ditch work is all in the Hondo valley. The Rio Ruidoso running out of the mountains feeds these ditches which irrigate the bottom lands in the valley.


Funny you mention the crawdads as I am a native of New Orleans and a good crawfish bisque would sound real good right now.:drool:

I picked up the Tongue and Hitch on Friday. I had the holes repaired in the Hitch and the bottom end of the tongue beefed up. Then I got it painted on Saturday.


While picking up the tongue and hitch, I dropped off the weight balance turnbarrel and spring adjuster nuts. I had made 3 each one half inch rod arms to weld on. They had them ready Saturday, after lunch. I had the length wrong on the turnbarrel and had to cut the arms shorter, do to me getting the swinging geometry wrong. As the turnbarrel shortens, the arms move aft and hit the front gang pivot bolt and nut.


Before I quit for the night, I removed all 4 disc gangs. I had 4 plow bolts spin and had to cut the nuts off with a high speed router and a 3 inch cutoff wheel. Two bolts sheared and the rest came off like designed. So it took a while, but the gangs rolled right off and the bearings all turn like "spinners", with no play in them.


While painting the area of the weigh adjustment turnbarrel, I found a frame crack. Well, now it will be a trailer trip to the welding shop.


So far, I have just used spray bomb paint. I did buy a gallon of Majic IH RED and a pint of hardener. I am not sure if I will spray it or roll it on. I'll get the shop cleaned up and ready to paint later today and plan on finishing the painting next weekend.

It's looking good. It'll be better than new when you get done with it

Brandi, you are doing a fine job that anybody would be proud of. That is gonna be one sweet disc when you finish. Your efforts are adding a tremendous amount of value to what was an aging sad implement when you brought it home. It will be a happy day when you drag that through some soil for the first time.:thumbsup:

Not to be a pessimist, But your 6520 will not be able to make use of that disk to it's fullest capabilities. I think that you will be using the transport wheels for more than just transporting. I hope I'm wrong, but I don't think so.

Good luck

According to Amco.com that disc needs 70-90hp. Tractordata.com says a 6520 is 92hp at the PTO, not sure about drawbar HP. It should be able to handle it depending on the soil conditions.

Wife and son have a Amco F-17 10'6" double offset tandem disk and the CaseIH 5140 2WD handles it fine. It's a heavier tractor but about the same HP.

I'm a bit surprised that the F43 has dual wheels. The F-17 here has singles but they are about 12" wide and it has the optional Shock Absorber Gang Risers.

bindian, Looking good so far except for the red paint ;-)

Her 6520 is not the 6520 that you are thinking about. It is a 65 gross hp Mahindra.

My mistake I was thinking JD, should have looked under the avatar. I gotcha. When my late FIL bought the Amco F-17 the biggest tractor he had was the IH 686 and it wouldn't pull the Amco. He had them install an M&W turbo and that pushed it up to 106hp on the PTO. I more problems with the Amco. He actually pulled a NH 2 row Silage cutter with it. I agree that the Mahindra is going to struggle with it.

Jim and Brett,
Thanks.
Cost of new parts is forcing me to not make it better than new. Take these disc gang mounts in the photos. A few of them have oval holes and some have feathered edges. I saw one pretty new one out of the bunch and it's hole is round. So I'm gonna ignore them for now and change them before their edge rips out.

Grateful11,
Thanks. Now, I see you have a Case.:thumbsup: Is it Green?:confused3: Also, if you read all my posts you would have read that I have already pulled it and the Big RED Beast pulled it fine. You would also read, before I pulled it, that I stated I would buy another tractor that could pull it. 2 wheel drive pulling tractors are cheap.

Now for a update on the model. The Amco rep thinks it is a either a WOF8, a WOF9, or a WOF10.:confused2: I have a basic one page parts breakdown on it and it looks like one of them. But they all look alike with some differences. He guesses it weighs about 3800 pounds.
