Transport Disks

Hi guys i am thinking of getting a small transport disk and have a question.How do you adjust the depth of cut . also what would be the best size for my 1070 john deer 4 wheel drive tractor its rated 35 pto hp Thanks art

you adjust the depth by using the hydraulic lift on the disc. I think an 8' disc would be ok for your tractor but in my soils nothing bigger then 8'

Why not go with a three point disk?

Hi Mr Tritoman thanks for your reply but i though that alift disk would be better at finnishing a plowed field and burying trash in the fall any comments thanks P.s. the closing wheels for my jd 71 worked nice thanks

A Disc is a Disc. Be it 3pt or a pull. I think your gonna accomplish the same thing. bjr

A transport disk is typically heavier, therefore may do a bit better that a 3 pt. Other than that they work the same.

Not only is a transport disc heavier it also floats with the contours of the ground. A 3pt disc you have to have a floating toplink in order to gain results close to a transport disc and even then a good transport disc will do a better job. 3pt discs are great though if you have small fields or are working food plots in tight areas as you can just raise the 3pt and go. A transport disc can be a problem if you get into a tight. So both have goods and bads but I would easily choose a transport disc over a 3pt for 99% of the discing work I do but then again the smallest field I work is 3 acres (its one of our food plots) so I don't have to worry about tight spots.

Hi guys thanks for all the replys I have another question dose any one have an idea on the price of a tufline tw72020 disk or similar type disk. Thanks art

We recently priced a 10' tl series and it was in the $4000+ range. Seems like a lot for tube steel and a few disks. Add hydraulics and the price will go up fast. Most pull types are for far more HP tractors than you have. If you are going to be transporting this around or have tight corners you may want to rethink the 3 pt hitch.

My 39 drawbar hp will barely pull a 8' disk in moist soil and would much prefer a 6 ft.

My tractor is a 4wheel drive 2009 JD 3720 (35 HP pto) and with loader and wheel weights it weighs about 4000 lbs. This summer I borrowed an 8 foot wheel disk and used it until one bearing went out. Time was short so I had someone else with bigger equip finish the tillage job. Late summer I found a 10 foot John Deere wheel disk on auction and bought it at a reasonable price. After fiddling around with the leveling hitch a while I got it leveled out. I found I could pull it just fine in ground that had been previously tilled. I pulled it as deep as it would go, and sometimes the dirt was piling up in front of the front gang (before I got it completely leveled out). This RWA JD disk is not angle-adjustable. If you have an angle-adjustable disk you can always back off the aggressiveness that way.
If you are trying to break heavy ground with it the 8 footer would be a much better choice. But disks don't really work to break ground anyway, and they will not do anything with sod either, so really you have to have it plowed or chiseled first. Now If I could only find a four-tine chisel to pull.
