What now? Disc won't penetrate

Re: What now? Disc won\'t penetrate

Slamfire,

What happens is that the cultivator catches on root and the tractor can't move forward, but tries. Since the rear wheels can't turn, the front of the tractor lifts up instead. The tractor has enough torque that it could just turn itself over backwards. A quick foot on the clutch drops the front end down again. Could be dangerous if you were moving fast.

Pilot, While I do agree that front weights won't hurt and I'd guess some of the reason a lot of us don't run front weights is we have FEL's which in itself is typically plenty of weight. If you hang an implement on something solid no amount of weight is going to keep the front down and even if it did something else IS going to break or crack the tractor in half. Gotta be careful out there and be ready to clutch or stop someway, even a D8 can lift up if you hang on something big enough with the rippers although they usually instead of raising the front end just dig themselves a hole and get real low to the ground quick.

Pilot.. I think the issue is .. that if your 3pt implement is attached correctly.. snaging an obstruction shouldn't lif tthe tractor.. the TOPLINK should prevent it, and stall the backflip.

Pilot,

Now I KNOW something is not right.

When you hit a root, the disc should roll right over it, lifting the entire implement up slightly. It should not get caught and prevent the tractor from moving forward. Are your discs balled up and not turning freely?

Are you really using a disc harrow, or a cultivator with chisel plows?

From his original post, I believe he tried a regular field cultvator instead of the disc ... don't think he's getting the disc hungup on roots ...

Re: What now? Disc won\'t penetrate

Pilot, I too am the proud owner of an Oregon blackberry patch, (aka timberland). Over the years I have used several methods to control them:

Method 1: spray with the appropriate chemical at the appropriate time then mow or disk. Some chemicals work better in the fall as they translocate to the roots, others work better in the spring and summer. Chemical selection and timing are important and you will need leaf area to absorb the chemical so mowing first may not be a positive step.

Method 2: Rip the the soil with a heavy shank cultivator and remove as much of the vine and root material as possible. Allow this to dry and it will become quite brittle. A disk may do some good after the majority of green material is removed.

Method 3: I've done a fairly good job of snagging blackberry vines (both out of the ground and out of trees) with my front loader and tooth bar. This will scrape them off the surface of the soil and allow you to disk more effectively.

Method 4: Mowing: blackberries do not tolerate close mowing. A season or two of close mowing, especially if chemicals/cultivation are also used, can clean up a problem.

Method 5: The ultimate: My favorite weapon is a toothed grapple that can pull, and rip the vines and disturb the soil all at once. When you are done with this method the soil is loose and you can disk mow or spray as needed to maintain control. Hope this helps.

Re: What now? Disc won\'t penetrate

Soundguy & others: You are right! The the toplink should prevent the tractor from flipping. It should work that way. All I knew was that when I caught the cultivator on an obstruction, the front of the tractor lifted up. I didn't test how high the front of the tractor would go--It looked like it probably came a foot off the ground and was still climbing when I hit the clutch. When it looks like the tractor is going to turn itself over backwards, you don't stop to measure how high it might go. So it might have stopped. Or maybe I had the top link hooked up wrong, but how many choices are there? Looks pretty foolproof, to me. So I don't know how far it could have gone, I just know the front of the little Kubota was looking for the sky.

I have switched to a Yanmar 180D, 50% heavier than the Kubota 6200, so I'll see if that works better.

As for the comment about a disc not hanging up, I was talking about a spring tooth cultivator, not the disc at that point. The disc problem was lack of penetration.

I have indeed had what you describe happen, but not when I was using a 3 point hitched implement. Properly configured, when the implement hooks something it tries to pivot on the lower pins and the top link pushes forward on the tractor. I'd imagine if the implement couldn't pivot on the lift arms something else could happen. Fergie spent a lot of time getting the geometry of the 3 point hitch worked out. If your tractor is basically a 2 point hitch model that's been converted, perhaps something is wrong.

Re: What now? Disc won\'t penetrate

If I did this right there should be a couple of pictures to follow of my weed farm. This is my lawn /forums/images/graemlins/crazy.gif, I had it leveled out 2 months ago and waiting for fall to seed. Tried running my 3 pt. disc over this mess but ground is to hard. Way to rocky to bush hog or till and york rake just glides over the weeds. I want to try to get the rocks out myself without hiring a harley rake and operator. But between work, vacation and building this house myself I lost the "War of the Weeds" /forums/images/graemlins/tongue.gif. My question is: what is the best way to apply weed killer to stuff this tall and what's the best kind /forums/images/graemlins/confused.gif. If I do plant in the fall is there enough time for the chemicals to be absorbed into the dirt so it won't effect the grass seed...


Thanks -Sarge
