I was raised in the country and have bush hogged and bailed hay all my life but this grass is a mystery to me. There is some bahaia grass, some bermuda grass, some Johnson grass and then there's this stuff I can hardly cut. If I cut it regularly its not too bad but down here where I live we have been getting raid practically every day. We are over 12" over normal for the month and it's not letting up. I will try to post a picture of this grass when it grows out and see if somebody can identify it.A 6ft hog with the 31HP L3200 should be quite compareable, as you say, to a 5ft hog run by a 25 HP L2501. The old "5 HP per foot rule." Of course "heavy" is relative and no telling exactly what the grass composition is like for TBone without being there.
