This is a grazing pasture with just an unchecked Spring growth of grass, about waste high. Would the RD990X be able to mow this?
Isnt the Woods RD990 a finish mower ? I have never owned a finish mower .

Set the wheels down as far as possible in the rear and a 1/2 inch less in front. Check your belt tension before you start and have at it.
Let it lay for several rain free days and hit it again using a different travel pattern.
