Will it handle it

[ole dummy]

Looking at a 6 1/2 ft United disc 20x20. I have a 3560 HST no FEL, will I be able to handle this disk or do I need to look for a smaller one?

Thanks
Rick

Thanks for the reply. Looks like it is right on the borderline.

I will be curious to see if it works for you or not, since I also have the 3560 and trying to learn the limits.

You will be fine in HST/PLUS MEDIUM, toggling between MEDIUM/LOW and MEDIUM/HIGH. You will need to keep seat belt snug in order to stay in the seat.

Without an FEL for weight in front you may need front weights if you have to disc up slopes. On level ground you should be fine.

A Tandem Disc Harrow with 20 pans = 7" spacing between pans which provides more float, less penetration, than 9" spacing between pans.

To keep straight I recommend you show "CAB" in your tractor designation. That 700 pounds of cab can make a difference at times.

I just went and added it. Thanks!

Consensus: A Tandem Disc Harrow needs 40 pounds of implement weight bearing on each pan in order to cut reasonably well.

A 6'-8" wide Box Frame Tandem Disc Harrow with 18" diameter pans has 35-40 pounds bearing on each pan.
Multiple passes usually required.

A 6'-8" wide Tandem Disc Harrow with 20" diameter pans has 40-48 pounds bearing on each pan.
One or two passes required.

A 6'-8" wide Tandem Disc Harrow with 22" diameter pans has 42-50 pounds bearing on each pan.
One pass usually does it. But too much for an L3560.

These numbers vary relative to thickness/diameter of frame tubing, axle diameters, number and thickness of pans.

As Grand Ls are standard with 2-WD, 4-WD optional, and some Grand Ls have rear tires inflated with air, others have rear tires filled with liquid, I speculate Land Pride recommendations are very conservative.

An old, worn Tandem Disc Harrow with worn bearings will pull harder than a new Tandem Disc Harrow.

What are you calling pans?

Thank you for all the information, learning a lot. Now if i could just get the rain to stop on the weekends and rain during the week, so I have a chance to go out and play with tractor and get some of the chores caught up.

I looked at the disk, it was in really good shape so I went ahead and bought it. Brought it home and unloaded it and hooked it to the tractor . Made a trip through the garden with it and didn't have any trouble pulling it. It was a 18x20 instead of 20x20. I will be trying it out on some new green fields in a couple in weeks, then I will know how it handles it.

I own a 6 foot wide Box Frame Disc with 16 -18" pans. My L 3560 has no issues with it when I let the disk pull deeply. I think I could go larger but do nicely with what I have. I have sandy soils......so clay or wet soil could be another issue. If you do have problems.....you could remove the outside pans and go a bit narrower.

I think he's referring to each individual disc on the disc harrow.

I had a 3940 pulling a 6' med/heavy disk in central AL where our soil was sandy/loomy. If the soil was wet/soft enough for the disk to dig deep, almost to the axle deep, my tractor bogged down and struggled. Where the soil was harder/dryer, I could pull at about 3/4 mph. The soil never flew off the pans. My FIL had a 85 hp New Holland with a heavy 8' disk and he would disk anything at 6 mph and throw dirt about 12" off the pans. Big, big difference in the quality of the disking. I'm going to suggest a HD 60" disk for your tractor.
