I understand your position. However as a golf course superintendent who runs 2 steiner I can assure you that cutting 6-8" is totally normal for any course. First off fairways aren't steep enough to need a Ventrac and there cut 2-3x a week with low cut lightweight fairway mowers. The rough is not kept low and neat its left to grow and cut weekly at the most and with thunderstorms and lightning we end up with 4-6" height pretty much weekly and occasionally higher. No one's mowing steep 30 degree slopes 2-3x a week, if they were they would be down to dirt in 2 months from scuffing up and down the steep slope. I don't care how well they climb at 30 degrees you will get some wear if cutting excessively.
... I love your videos and products, but I still don't believe that the 25 diesel with 84" deck is suited for any steep slope mowing. In 2012, 25hp motors running a full hydrostatic drive(horsepower robbing) belong on 50"-60 decks at the most. For what that machine and deck cost with duals in the 30,000 range it should have performance to match the size of the deck and cost of the machine. What Ventrac really needed to do was go with the much stronger, longer lasting, more efficient 3000RPM diesels . There are so many to choose from in the 32-40hp range..The 3600rpm diesels are not the best choices for hp requirements of the 4500,but there cheaper and smaller than the 3000 rpm models and prevents Ventrac from having to make hydraulic pump alterations to run. them. So I understand it, but I don't think what's easiest and cheapest is always the best...
