Amco Offset Disc

[bindian]

I am not sure what model Amco offset this disc is. I do know it was built in Yazoo City, Mississippi. I am thinking:confused3: it is a vintage F42 model Heavy Duty. It is 8 foot 6 inch wide with 24 discs that are 22 inches in diameter. The discs are on about a 9.5 inch spacing. It is suppose to have dual transport wheels, but only has 2 with tires and one axle assembly missing and one unused axle with no hub. So it needs one axle and two hubs with wheels. I gather this disc is around 4100 pounds. Best I can figure (in my online search) is that it is a F42 Heavy Duty disc. I need help in figuring out the exact model.:anyone:

I won this disc at Richie Brother's Auction in Houston last Wednesday. I bid more ($2500)than I wanted, but now am glad to have it.:cool2: Amco's webpage says a new F42 HD sales for right at $16,000. At least one existing wheel bearing needs replacing. Somebody painted it green, years ago over the yellow. It will be RED very soon.

The closest Amco dealer to me is 2 hours away in Giddings. I hope to stop by there next Friday or the next Friday. So any help will be appreciated. I am new at using an offset disc. I have only used 6 foot 3PH (spelled LITE WEIGHT) in the past. I need advice on how to adjust it on all the various gang settings it has and spring adjustment.:confused2:

It is in the barn now waiting to have the the hoses and cylinder purged today. Yesterday evening I got excited just staring at it's immense size and then got misty eyed thinking of Dad and how many hours he pulled a disc bigger than this one.

Nice disc. Looks like it's worth $2.5K.
Hope your 6520 can pull it.
My 5525 has trouble with my 6.5 ft Towner offset disc in soft soil. It's a pure drag type--no transport wheels like yours.

Good luck.

Nice looking disk and pretty heavy too. Had a 6 1/2' like that years ago and will say those spools between the blades add lots of weight. Sure would like to find another one like I had.

Thanks Guys.

Flusher,
My concern was my 6520 pulling it, also. The guys that sold me my 6520........and that ran a Mahindra 7520 haying and discing, told me my 6520 would pull it and that if it got to hard pulling, to just raise it up with the transport wheels. I'm not too concerned. If my Mahindra is a little on the small side, I'll just buy a dedicated tractor for pulling and 3PH work, as I really like to keep the backhoe on the 6520. Mahindra has that 100 hp tractor out now. Maybe they will come out with a bigger Bradco backhoe to fit it. Also, my neighbor has 100 acres a stone's throw from my back gate and is working up a herd of Black Angus. He has no tractor and says he won't have to buy one now that he knows I am nearby and willing to work for him. This disc will fit into my business/retirement plan nicely.
hugs, Brandi

Boone,
Thanks. It is always a pleasure to hear from you!

I stopped at a truck stop to refresh on the way home with it. I looked back at the disc on the trailer and wondered.............will my tractor fit on there with the disc. When we unloaded it yesterday, I purposely backed the tractor over the tongue until it touched the spring "pogo stick" that holds up the hydraulic lines to the cylinder. It just barely fit with the loader lowered after the ramps were stowed, just missing the front tractor tires. Whew...........I thought I was gonna need a longer trailer!

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

While not familiar with this particular disc, I would say that the wheels need to be in contact with the ground at all times to control tillage depth. A good match between tractor size and disc size/type doesn't mean that the tractor can always handle the disc when cutting maximum depth. (down to the spools) The tillage depth needs to be controlled by the operator and most hydraulic lifts will include an adjustable depth stop for this purpose.

Brian,
I agree to you using the word "fullest". I am a firm believer in having too much tractor and now,.... .........that 100 hp Mahindra is looking better and better! I'd even consider a used, different color tractor to have just for pulling. We'll see what the Big RED Beast can pull first!

Npalen,
I agree. This disc does have holes to lock the cylinder lift assembly into different heights (settings) when in the ground. But I realized it will be the remote lever setting the height and fine tuning it. I am not gonna disc with it until I get all 4 wheels back installed.

Brandi, It's not just the HP, you need some traction also. To handle your disk without problems, I would say 14-16k pounds with 100hp. The 100hp Mahindra ain't gonna cut it.
Honestly, as soon as I realized that the 100hp model was not a bigger 8560, I lost about all interest.

I undestand about the traction. What.........the 100hp model won't be bigger than a 8560, as in heavier also? That sucks. Oh well, I know where a New Holland Versatile is and soon it will be on the market. I am sure the owners will let me borrow it to try it out. They pull a 24 foot disc with it.

A new Amco 8 foot 3 inch offset disc (F42 Heavy Duty) is $15,945 plus options. A new Amco 9 foot offset disc (F42 Heavy Duty) is $ 16,402. I made out like a bandit. For the difference in new offset disc and what I paid............I can buy a good used pulling tractor.

Brian,
Do you have any specs on the new 100hp Mahindra?

I bought a 13-ft wide Minneapolis Moline KS1300 tandem wheel disc (made by Krause) from Dave at DavesTractor (my Mahindra dealer) a few years ago. $600 including delivery by Dave and one of his guys. To handle it with my 5525, I cut it down to about 8-ft wide. Works fine in dry soil when I get the hayfield plowed in late September (after 3+ months of summer heat to bake out the soil). Like you, I use the transport wheels to adjust the depth.



Have fun with your new acquisition:thumbsup:

Flusher,
I have heard Krause products are very durable. How hard was it to cut down to 8 feet?

I plan on having fun with it. Thanks! I could have bid on a 12 foot Tuffline disc, but it had at least two gangs needing new bearing and maybe axle shafts and it was all rusted up. My Amco, you can spin all four gangs and the first gang is still spinning when I get around to spin the last gang.

Not very difficult job. Bought one of those Harbor Freight portable band saws and used Milwaukee blades. Cut through that square tubing like butter.

Portable Band Saw with Variable Speed

I shortened the axles and drilled a hole in the ends for a big cotter pins to hold the disc-spacer assemblies on the axles.

Use two of the scrap pieces of 4x4 inch tubing to fabricate supports for the transport wheels to move them more toward the centerline of the disc main frame.Welded the new wheel supports into place. I just left the old supports in place on the ends of the big axle that's part of the hydraulic lift assembly. This step was the most time-consuming part of this project.



Hope this helps.

I just look at the TYM specs. I know that they are not the same, but close enough to get an idea. I hope to see the actual tractor at the Tulare World AG Expo this week. I'll be sure to get pics if it's there.

I have seen these saws in action. They are slick. It could be harder to cut this disc down. It is all 1/2 inch thick angle that is 4x4. Of course, I don't wanna chop on it. I'd get a bigger tractor before putting a saw or gas ax to this heavy weight.

Brian,
I have heard the Mahindra 100hp tractor will be better than the TYM. Hopefully it will be way heavier.
