[AT] Pasture drag, rake, ???

[Dean VP]

I have 6 acres that I mow with my Garden tractor 3 of which is a pasture on
a slope which at one time had horses on it.  Now I try to keep the pasture
looking nice by mowing it with my Garden Tractor albeit at a slightly higher
cut than the rest of the regular lawn. The last couple of years the pasture
has gotten really rough from multiple sources including our not so friendly
Moles and pocket gophers. There are several old growth stumps buried in the
pasture which was well done except will the dirt fill occurs it doesn't
completely fill all around the stump down below. So over time and our
incessant rain some settling occurs and even some small occur.  I try to
fill the gaps with dirt as I find them but each year 2 or 3 more show up. So
bottom line is the pasture has gotten rough and beats the crap out of me
when I mow it. I would like to use a tool to try to smooth it out a bit and
thatching the grass mat in places would not be a bad thing.   But our soil
is terrible and at best could described as glacial till filled with various
sized rocks.   So I really don't want to disturb the rocks too much since I
have to mow it later.   So I want to smooth the soil out, not disturb it too
much.  Known as a quandary. 

I'm thinking about acquiring pasture rake or drag with short teeth on it to
work the top couple inches or so and  try to smooth out the mole and gopher
mounds which I have manually knocked down a bit prior to mowing,   I have no
experience with a pasture type rake.  I have experience with a spiked
toothed drag we used on the farm in NW Iowa.  But that was used to smooth
out  loose ground in preparation for planting corn or soy beans. That isn't
what I need. I think I need maybe 4 4' square flexible sections that can
flex with the varying terrain and catch the low as well as high spots. I
think I can pull an 8' 8' unit with my 20 to 22 HP Garden tractors. I'm more
concerned about traction but I can put chains on if necessary.  I'm thinking
I would want to take several passes at various different directions.  And
hopefully I could use this same implement to dethatch the rest of the lawn.

Some of you surely have experience with something like what I need. What do
I need? What are it's critical attributes?  Where do I buy it?  I do live in
Horse country so there are a few stores that cater to horse owners and of
course I have Tractor Supply, Lowes, Home Dept, Grainger, etc. and ???/

I'm looking forward to being educated.
