Mowing Discing vrs. mowing

[project]

TSC has a 16/14 inch notched blade disc for compact tractors. I have a Kubota 7510 Gear. I thinking about trying to disc rather than mow . I have about 3 acres to turn over for grass control. I 'm not trying to prepare for planting. Winter and spring , the ground will slice like butter. Summer will take explosives. I've done discing years ago and know what it takes using larger equipment. My question is, can a 21hp tractor pull a small disc (don't know the weight) with reasonable success?? thanks

I saw the same thing at TSC and have the same question, but with a BX23. The soil I have here in Western CT varies only slightly throughout the year, early spring it will be a little swampy, late spring through the fall is generally nice moist loam.

I wouldnt be afraid to hook on to it! Year ago I had a small Kubota ( a B5100 I think it was?? 2 wheel drive..stick shift..12 HP diesel model) and I used a 4 ft set of disks with it here. Had to add weight to it in fact.

I wouldn't go any bigger than a 48" disk with your B7510.

?? Its rated to be able to operate a Kubota 57 inch rear tiller. Certainly it SHOULD be able to pull a 60 inch wide set of disks....depending on their actual weight.

I think the small KK set is about 4 1/2 feet wide.

Yes... but it is powered and he is not trying to pull it through the ground.
The only thing I can relate to it is when I had a B7500 and had to load the rears to pull a 48" KK BB without spinning the tires.
I never did pull a disk behind it.
I did try to pull the disk I built behind my 2wd 15hp Mitsubishi LOL that was a joke...can you say boat anchor and I only had one set of gangs on it at the time..with both gangs it weighs 663lbs and it's only 60".
I still recommend 48" a few inches won't matter.

True...very true! I looked at that series once...just thought they had more "grunt" than that??

Project, as long as your tractor can lift it, you should be fine with a small set of harrows. The question comes in to how deep you are able to cut. You will need to load tires if you haven't already. If while cutting you hit a soft spot causing your tractor to bog/dig, come up on the lift a little. Work it as you plow. However, with a small set of discs, you will probably be more concerned with getting them into the ground rather than out. If grass is invovled, they like to ride over it.

However, this is a good way to encourage a running grass to spread. Bermuda loves it when you loosen the soil.

You've got plenty of horsepower but you need a lot of traction to pull a disc. Add some ballast and go slow. Think about all those old Allis-Chalmers Bs and Farmalls. They had less HP than your 7510 and were only 2WD yet they could pull discs and 2 bottom plows without any trouble. The reason is because those machines weighed a lot more.

I have always been amazed at what small wheeled tractors pull in the east/midwest. Here in the Calif. valley Holt invented the crawler because a wheeled tractor was next to useless with a plow or disc hooked to it. Everyone had a crawler out here. D2s-D5s/td6s-td9s were the common tractors around here. I never saw a wheeled tractor hooked to a disc or plow out here until the bigger tractors started showing up in the 60s/70s. Those rubber tracked things are now the workhorses out here. I know a D2 will pull a 5' disc pretty good out here. A 4' disc is as big as I would attempt on a small wheeled tractor out here.
