I cut straight lines in some places, and go Zamboni on the bigger areas. Mine is a tough yard to cut. I mow about 5 acres with lots of random trees, steep-ish hills, a 2 acre pond that's spring fed, so up at the shallow end, the ground is always mushy and the grass there always grows like wildfire.
I run the JD 425 for about 4 hours, then the push mow under the fruit trees, and close to the back porch and patio for another hour. I finish up with the weed eater along the water's edge, around the tree trunks, and edge the flower beds for another hour and a half.
If we have enough rain in the summer, this happens every weekend.
