I have 130hrs on my 990 that I bought on new years eve of 03. It is 4WD, PS, with the 430 loader and R4 tires. I use it for moving trees, splitting wood, cutting grass, moving dirt, hauling debris, grading my driveway, and general maintenance of 10 acres. My tractor experience is limited in that my previous machine was a 850 that I had for 6 years. That said, the 990 is a wonderful machine. The only limitation I have found is the capacity of the 430 loader. It struggles a bit to lift out a full gravel load.
