I have a Hustler Z. There are 2 accounts with steep hills. One is a corner lot, with the corner being a lake. The owner states that in the 30 years he has lived there more than once a mower has gone into the lake. I started mowing this property using a John Deere 14 sc, wearing cleats and will refuse to do the job unless the grass is completly dry. I like the challenge. It could be an hill climbing event, like the Lawn Mower X Games! I've heard about the stability of the Hustler Z, but have yet to try it out on this yard. 1. Is any one else doing the same thing? 2. What is the safest technic for mowing hills with a ZTR? 3. Whould weights low at the very front of the unit help things? This is a very Good paying account and feel it can be done safely with my equipment, using the cleats and walking only on the steepest part then weed eating the rest. 4. Anyone use ROP? 5. Will the oil pump starve, destroying the engine? 6. What do you feel is the safe limit never to exceed, thinking of installing a incline meter.[Level Gauge] There is no room for trial and error on my part.
