Disc for L4400

[zkubota]

Wanting to get a disc for my L4400. I'm thinking 6 to 9'. I know weight is a concern, but what variations on a disc are there? different type edges, different stagger?...or are they all the same.

BTW: I'll just be keeping my MX track disced up.

Any resources for finding one used in Arkansas?

With 45 engine HP you can handle up to 9' if not plowing too deep or too heavy of a unit.

For maintaining a track, I'd probably look in the 6-8' range among 3pt. units with solid discs as opposed to serrated....you're wanting to smooth and condition a prepared area versus bust-up new ground. An older, used 3-point disc that you could attach a drag of some type (pipe, RR tie, etc) sounds like the ticket for you.

Resources? I did a quick search on tractorhouse.com and fastline.com but didn't find much in the way of small used discs in AR. Craigslist maybe..???

If you wanted to get really wild, you might look for an older 9-10' drag disc-harrow. These have suspended disc gangs and a lighter build and are mainly for levelling already plowed ground in prep for planting....look like a "disc plow" but are more of a harrow.

I'm pulling a 10 ft disc using a 45 hp tractor with no problem.

Mornin Zkubota,
I agree with the others, your 4400 should pull 6-9 ft harrow no problem. My Massey 1040 , 3800 without the loader pulls this Taylor Way 7 ft harrow no problem. I have only played around with this harrow mainly because I have a few more things to fix on it but its a good match IMO !

What exactly do the serrated disc do that the solid do not?

Is there a certain type of design to stay clear of, say a particular way the disc are hung on the rack?

Serrated discs are better at chopping up plant residue. Probably irrelevant for your use. Smooth disks leave a smoother finish.

Disks are really pretty simple. Main issue is bearings - are they in good condition if it's a used unit? Older style is greasable bearings. If they are greased each use, it is very durable. Older-older style is oiled wood block bearings - easy to make new ones, and reasonably durable. I doubt anything made in the US since 1960 has wood block bearings. Most modern is sealed bearings, which are no maintenance and work fine, but may not last as long.

I have a 6.5' disk that I pull with a 50hp tractor. No issues. I agree with other comments on what you could pull, but I'll bet something like 6' is going to be most practical for your track work.

"What exactly do the serrated disc do that the solid do not?

Z-man summed it up.....serrated discs are for trash cutting and getting a better bight into harder ground. Smooth discs are for conditioning and loosening.

No, no real design to stay away from especially in your case where you're looking for something to simply powder and level a course. If you need it now, look around at some of the local dealers for a regular duty 6-9' disc (Howse/King Kutter/etc) and add you a little drag of some sort. If no hurry, dig around and find an older disc sitting in someone's yard or out back the dealership. Nothing wrong with the older units with greasable bearings.....unlike sealed bearings, when they get a little play in them you can just pump a little more grease in them and go on. When sealed bearings go........they go.

For you, I'd say find some older unit which might not be so pretty (but not rusting to pieces), grease it up, and take care of business.

Rarely have I seen a more aesthetically pleasing and proportional weight than your chained-on 10' (12'?) section of I-beam.



Nice......

if you're just looking to keep the mx track "groomed" then i would go w/ a med or light duty disc. i think a heavy duty w/ the extra weight may cut too deep and you would have a very soft track. w/ a med duty you can always add the extra weight if needed. i have a jd105 disc 6ft which i pull w/ my 790 it handles it well in most conditions but when its a bit wet or heavy soil i def need 4wdm and could use a bit more weight on the tractor.
