Hi, I have a Kubota L2650 4x4 29hp. I am looking to buy a 3 pt. disc. What would be the correct size and/or weight to use for this tractor. Only have about 15 acres to work, however the soil is subburn. Thanks!

Normally about 6' or 6.5' is about it but it does depend on if it is plowed or not as well as your type of tires. ....

If you know someone who has a disk about the size you think you can use and they will allow you to try it I would before I bought one. To me there is more to a disk than many think there is. Based upon my tractor (68 hp 2wh drive) and disk (9 ft)combo you would never pull a 6 foot in my dirt. Hard dirt can be easier to pull in than sandy dirt as the disk does not cut down into the dirt and you have better traction. If you dirt is real hard, a light weight disk will probably just ride over it. How deep you plan on using the disk also greatly affects what you can pull. One big item I did not mention, if you are pulling real slow you might could use that combo here, but the action you get does not break up the dirt as well at slow speeds. kt ....

Thanks for the feedback! All the tires are V-tred and the rear are filled. The soil is sandy. ....

Art knows his equipment and is a true professional. His suggestion will work for a lot of people.
I normally run a leveling bar on my disk. If you will be using any such device you must take that into consideration. To me a lot depends on your wants and needs. You will find cutting 4 inches deep at say 3 or 4 mph on flat land to be so different than 5 mph 6 inches deep on slightly rolling land. Of course the angle the blades are set also affects. You need to know what you want the dirt to be like when you leave the field. For "my use" I rather have larger blades and more weight per blade so I can cut as deep as desired and trash. It surprises me the difference between brands of disk in how they cut and how hard they are to pull while their specs can look alike.
The size disk you looking for probably can be found in the used farmers market. If you buy any used equipment, be sure you can get the parts for it. With disk that mostly means bearings. kt

Another critical factor is the angle-of-attack of the V-formations of the disk axles themselves---the more they form a tighter V, the more power it takes to pull it. ....
