LPGS sizing

[jenkinsph]

If your road is crowned and you run your LPGS along the edge of the road and on one side of the crown in general you will not lose your crown. If you run the LPGS centered on the crown down the center of the road you will start to flatten the crown.

I agree with this^^^^.

I have a 4 ft and an 8ft lpgs, if you use it for driveways it is best to have one that is half the width of the drives. I use these for smoothing fields so the wider widths are better for that job.

A 70hp utility tractor with proper ballast should handle an 8' lpgs easily. Your 4020 could handle 12' model.
