Whitearrow,
On some level flat ground, like a driveway or similar, raise the hog up and measure the distance from the bottom of the blade to the bottom of the side skids. (block the cutter so it won't squash you or your arm!) Then measure the distance from each side skid to the ground at the front and the back. Adjust the lift arms so the cutter is level, both fronts are at the same height and both backs are at the same height. Then lower the cutter down so that the back wheel is on the ground and the front is at the cutting height you want. Measure the skids at the front and back. The front should be about 1" lower than the back. If it isn't, you need to adjust the lift and / or the back wheel. After the cutter is at the correct height front and back, then adjust the top link. You want slack in the top link on level ground, so that when you crest a hill, the cutter can follow the ground. Most cutters have a swinging top link attachment point. Looser is better than tighter.
I like to cut in the 5-9" range, depending on what where and why I am cutting. Higher for rough areas that haven't been cut in a while that may have hidden treasure. Lower for roads and trails. Sometimes even higher in the 12-15" range to refresh a clover patch.
Oh, cutting the dirt will both fill you up with dust and empty your wallet of $$$ as it does bad things to the gear box, output shaft and blades over time. Having a heavy cutter won't hurt your traction, but will lighten the steering. If you are getting stopped, you are hitting bottom!
Once you get it figured out and do it a couple times, it will a snap.
