How steep of a side hill can one mow with a Quick 36 and/or 44 and keep a relatively straight run? Can you do this with the steep saver? Also how much of an incline or downhill can you safely and realistically mow? And while we are at it what about scalping in the crowned areas of some swells? I figure the Q 36 would be better than the Q 44 in this department. Any input appreciated!
