What happens when the topsoil contains rocks the size of basketballs?
What happens if it hits a shelf of shale?
They never seem to have that in the demonstration videos. Google fails
to answer these questions for me.

We did extensive testing…
Our LM42 we bought was great with direct burial, but not good with a
chute for ¾” pipe.
It was reliable, but in harder ground it was an issue – no setting for
the angle when going shallow.
We even custom built a chute… great concept, but not practical for our
ground conditions
Single tires with good rubber is OK, duals are better for harder
ground.
We went with a zahn (mini skidsteer) that is tracked and articulated.
The angle of the plow can be fully adjusted to the conditions
With a serrated blade, we can easily go through roots… even a couple
inches of frozen ground
We use a “Bullet” style to pull the conduit with a carrot or kellum
grip (Chinese finger trap)

video is for a silt fence, but it gives the idea of why this works very
well
A team of 2 guys can easily do 5-8 houses in a short day (conduit).
Tracks, and articulation…. Is the secret. So is slow and constant
speed
Rushing the install….. results in stretched/broken conduit.
We also bought the “mighty mole” attachment for compaction boring under
cement driveways.
This wasn’t cheap, but it is very effective / clean / fast

make sure to sleeve under driveways with good conduit before pushing
through fiber or a smaller conduit where needed
For some of the bigger acreages, we pull in with the RTX1250 and use a
bullet with 3/4 conduit or chute with 1.5”
The ground disturbance is more, but doing this… it impresses the
farmers when we are “rolling black coal”
We also protyped a conduit pressurized with water and a jet where we
attach a carrot. The water helps for sure, but at some point… the
added work for the water/equipment was just a little bit too much to be
practical. Another one we looked at was sending a stream of water down
the plow itself, but then we need the water source moving… and it used
a lot of water to be effective. Think of how a big tree mover sends
the big knifes into the ground easier with water…that was the model we
compared it to. Very functional… just impractical in practice.

I'm trying to decide what make/model of plow to get. The options, as I
see them, are the Vermeer LM42, Ditch Witch 410SX, or Case Maxi
Sneaker. I'll be using this for customer drops as well as some
main-runs.
I like the mini excavator attachment for the LM42, although I don't
know how limiting this will be for the machine if I'm also using it for
customer drops. The drill attachment for the 410SX also seems like it
could be useful.
Anyone have experience with these machines? Recommendations?
Also, does anyone know what model of Case Maxi Sneaker this is?
