Seeing the name Seldovia, let me offer some thoughts:
You can get away with no grooming, and just land and take off with enough power. I have taken off with the belly in the snow.
Do you really want to do that at your home strip? Seldovia gets some warming and rain, and deep snow. Think about leaving tracks in 1' of snow! How hard will they be when it freezes back down!
The reason to groom is to have a smooth surface for continued operation. Tracks compress the snow, the snow becomes HARD! The next time you land you will run into the hard snow and it causes impact to your gear...
Then it will get warm, and you will take off and making ruts, the sides will be compressed, and when it freezes you have a ridge. Land and bang into that and you might break something.
I once landed at my remote strip in 33 degree weather, jumped out and chased the wolf that was crossing. Because I did not get the strip groomed and it then got cold that night, the strip froze solid I had ruts all winter long that would jerk the plane around if I hit them wrong!
So from the simple to the lengthy:
1. Get a small sled like a tundra or bravo and invite the young neighbor kid to drive up and down for an hour. You will need to do a bit of fixing after, but not much, (you buy the fuel). Kids get to go riding, you get the strip packed.
2. do it yourself
3. get two pallets from somewhere and set them side by side, tie a line from the back of the sled to the front center of the pallets; if deep snow a pre-pack will be needed. Pull the pallets up and down to take out the ridges in the snow. Pallets will last a couple of groomings before coming apart.
4. Tie a log sideways to the back of the sled and go
5. Take a couple of 4x4's and build a simple aframe drag. You need to make it wider than the sled, but depending on the sled size you need ot have it where you can pull it through a foot of snow. Make sure you have cross members to support it, and to act as cutters when it is a bit of crust on the top. (a ladder sideways will help or work as cutters also). You might need more weight on the Aframe depending on conditions and sled type. Trees or more lumber can be tied on to make weight adjustments easy.
6. make the aframe out of steel
7. What MTV said
8. Buy a fancy groomer for ski trails to pull behind the sled
The key I learned for smooth strips is that you need to do the grooming when the snow is soft enough to flow, and have a drag that will cut the surface high spots and carry some of the snow into a low spot and let the snow drop out. Having a front and rear sideways cutter, (two poles/boards) spaced a couple of feet apart perpendicular to travel works great. The longer the groomer the less wavy the strip will be.
Skis from a sled will leave tracks, so a groomer behind will remove those for a smoother surface. Once you do groom it is best to depart off the end, turning out on the fresh groom will leave tracks, which when frozen will be hard bumps. Let the strip settle and freeze up. IN cold weather it might only be an hour, or you might have to wait over night. A foot print should not be a hole when it is ready.
Note: As you cut and roll the snow with the groomer the moisture will be released a little bit, so once it is back on the surface and left alone it will freeze the snow down hard.
If you do leave tracks on soft snow, the sooner you groom it the better chance of having a smooth surface the rest of the year.
Starting with fresh snow and keeping it groomed will make it easy, trying to groom after it has been rutted can be a pain in the tail.
Old cutting edges from graders make great groomer cutters, and can often be gotten free at the local plow yards.
A well groomed strip will hold out longer in warm weather, and be much less wear on gear. They also work well as a drag strip too!
