Coulter for disc hiller

[oldnslo]

Something like these?

Those look like they rotate some so would not work well fir this application.

For the OPs situation; would a old spair tire wheel, possibly with a spring, putting down pressure, work? I would think that would resist the torque better, ans I'm sure you can find a wheel bearing, couple pieces of steel tube, and a donut rim, probably on the side of the road.


I'm not entirely sure how your row spacing is working; do you have basically a 6 ft dead row between your actual rows?

The vines/trellis are on nominal 8 foot centers, but they aren't laser straight and vines don't always behave well. So in the tight spots could be 7’. I keep a center 5’ strip of native vegetation (aka weeds) that I mow with my 5’ rotary cutter. I till the rest so vines dont have to compete with weeds

Great idea! I have some old rims lying around. Maybe even a wheelbarrow rim with a Grade 8 bolt as an axle. When I tried it out today it skewed pretty badly. I’m thinking that I’d need a couple hundred pound counterweight over the rim/coulter to drive it into the soil. I have about 150 lb of 2” heavy wall tube in the tool bar frame and another 50 lb in the 3 pt 2” receiver hitch, so more weight would help. Wish I had a hydraulic top link, but that’s another project. The rim would also act as a gauge wheel better than the coulter. Must sketch

3 point mounted cultivators for corn rows had straight colters for the exact purpose you describe. These typically were U-bolt mounted to the main beam. Not sure if there are any farm equipment bone yards in your area since around here almost no one cultivates anymore. All chemicals for weed control

90% of the agriculture around here is peach orchard and grapes. So there isnt much cultivator stuff in the scrap yards. I did find a free 1970’s Burch disc harrow that I rebuilt to cultivate the row middles.

Sad about the chemicals. Around here just about everything is Roundup resistant and folks have to use some pretty nasty stuff

Exactly. Is the linkage above the blade for a spring or for height adjustment?

I use a few 3 furrow plows but never on virgin sod. I took my coulters off and never use them. Sitting in the barn somewhere.

Don’t suppose your barn is in Colorado?

Rotate is probably ok so it will roll over rocks?

Only if the Wizard of OZ blows them over

Do you think this might work? Front wheel drive cars often have a hub assembly that bolts to the McPherson strut. Many cheep chinese knockoffs on ebay
