Thanks for all the great advice guys.
I ended up doing a little work with the Kioti this evening. Keep in mind that I've never really driven a tractor before. This past summer I drove my father-in-law's early '80's model Case around a lumber yard about 20 yards at a time. So, today was my first "real" experience actually operating one. After about 5 minutes of actually admiring the machine sitting on my property, I went to work. We've excavated a house seat where we plan to build a house later this year, so I have mounds of dirt sitting everywhere. So, I decided to lay into one.
My first impression is that the KL130 loader isn't exceptionally powerful. Of course, I'm sure there's some technique I'm lacking just yet. Nonetheless, I sank the bucket up in a mound of dirt, but it wouldn't lift a scoop out of it. I know there's the curl/lift technique that you're supposed to use, but I'll have to work on that. But I really expected the loader to lift out of it. I had to back up a little bit to lift or curl. But it has rained here for 2 straight days, hard at times, and that probably has a little (or a lot) to do with it. And after researching a little, I think the issue wasn't the loader's power so much as my inexperience. I was trying to lift very wet soil that was piled up almost 3 months ago. My kids have played all over it, it has rained and snowed on it. I didn't loosen the soil at all beforehand. I dug in at the bottom of the pile and tried to lift. The mound is about 5' high and I'm not sure what my RPMs were. The Kioti was probably rolling it eyes at this time

cursing his misfortune for having landed in the hands of such an incompetent operator!
Next, I decided to take some washboarded gravel humps out of my driveway. My driveway is sort of steep in a section and the new gravel we got about 2 months ago made a series of 4 or 5 decent-sized humps from the traffic going up the hill. So, with the tractor pointed up the hill I back-bladed using my FEL. That worked out pretty well. But the middle section of the driveway is humped up from years of traffic and I had a hard time actually getting down to the gravel in the wheel paths. But the hump didn't last long once the Kioti layed into it!
Lastly, I learned a valuable lesson that should have been a no-brainer. I decided to drive the tractor down into this big swag, on the side of which is a long ditch that has remained uncovered for about 7 years (see earlier post). Once I got down in the swag I remembered that it had rained 2 days straight as the tires sunk up quite a bit. It was VERY marshy. Nonetheless, I tried to back my box blade into the mound of dirt to cut it off and push the dirt back into the ditch. I think it would have worked out well if I would have had any traction. I put it in 4WD and sat and watched all 4 tires spin and fill with mud. So, lesson learned...tractors don't like mud!!
