No till mole plough

[Old Spot]

Been trying to do this for a while
Knocked this up, works a treat, no heave

Is that down to 24”, where is the expander?

We need a 485 hp quadtrac to mole our ground properly with a twin leg. (Or a Cat D8). I'm not sure you're going to be doing the same job!!
How does it keep it at a consistent depth?

This certainly is not moling as I know it but I can see it’s use and think it could be good. We get tramlines and high traffic areas that could do with water letting down without needing 400hp which we haven’t got our 200hp tractor struggles with one leg. How deep will it go will it get into gravel properly

All good comments,
I am trying to go in at 16-18 inches across the land drains.
My land is flat heavy clay, I now only farm a small area so drive at 3.6km/hr
I was aiming to put a depth wheel each side but tractor keeps it amazingly still
I used a single leg golf course/turf mole plough to get zero heave - this is mark two
It’s just to assist with drainage after planting

Sisis make a mole with a reared angled leg for putting drainage in amenity grassland with out heaving. Does a very good job. Add in an expanded on the bottom of yours and you’ll have a great machine to getting the water away with out needing huge HP.

If the ground is fairly even with a bit of fall, then a mounted mole can work quite well.

Be careful though if crossing rutted tramlines. I think that caused a lot of trouble in one of my fields where the moles failed at the headland tramline and caused water to drain to and water log it. I have since changed from a 2 leg fully mounted to a single leg sliding beam to help prevent that happening again.

Mole never needed that much power to pull. At low speeds though over powered tractors are an easy way to have enough weight for traction required to pull one.

It looks like @Old Spot has only got around 3" bullets on that as well. I am tempted to change mine from a 4" expander to a 3" and narrower leg for laying good moles without having to go so deep.

We have a single leg mounted mole and it works quite well at 18 inches in some heavy clay so I am sure that would be fine for a small amount

Knowing the depth of the gravel is essential for shallow moleing

 

[Matt L]

With shallow moling you run the risk of them collapsing by field operations happening after.
You definitely need to check the depth of cover to the gravel backfill if you want to go for shallow moling

 

[Wombat]

Or go straight into the ditch

You need length between the skid and the blade to get a mole plough to contour best.
You also need undisturbed (firm) soil above the tip of the torpedo to hold it in the ground.
