am very sorry but i have to get in here too!@!!!!!@$@$!@!-
i have a hard time with this slope business, it seems that everyone in the USA is attempting to defy gravity not just on this sight but every other mowing, landscaping, atv and tractor site.
so far i have only seen one person to do the right thing. Mossroad went to his kohler dealer and bought the book to find out under other what the particular engine was rated for.
all the meters in the world, all the blast, the wider tires and every other darn thing mentioned by the hills side tractor engineers on this site and all the other aforementioned locations forget, that you are taking your life in both hands if your engine fails because of lack of lubrication.
not to mention the cost of rebuilding or replacing an engine due to lubrication failure. FORGET the warranties, the coloring of the engine to a trained engineer in case of lack of lubrication is very easy to detect.
then after you know what your engine is capable of as far as degrees or percentage of incline it is rated, maybe the time has come to add another thing to watch; rather THAN where you are going.
i defy anybody to come to my birthplace and work on the mountain sides to carve out a meager, living watching your inclination meter rather than where your going and you may not come out alive.
