Well, here is my 20 hour update. I love it! I have cut the grass 3 times (about 2 times more than my wife thinks I should have), hauled a 10 cu cart full of rocks, hauled mulch all over the yard, helped my neighbor move his mulch, got 3 loads of firewood from my neighbor down the street. It never seems to slow down even when loaded down with the rocks. The cart I have converts to a wheelbarrow, so the tongue is 2 pieces. This helps with stopping because it gives a little. I have not had any problems with the slopes or unevenness of the yard. I set the tires to the proper inflation and the ride seems pretty good even over my very bumpy yard. Like I say, it doesn't seem to even notice the loads I have put on it. Beats the **** out of spending 4 hours push mowing (now about 1.5 hours).
