I am having my new 48" fixed deck walk behind delivered on Monday afternoon. I am such a newbie at this machinery that I am hoping they show me all the ropes. In case they don't, what topics should I be sure that they cover? What questions should I ask? I know I want to know about setting and resetting the deck height, if it is possible to change the rake and the best angle for our grass type, how to change the oil, remove the blades for sharpening, what pressure to keep the tires at, where/when to apply grease to the machine, and starting/running instructions (e.g how to start it, what throttle settings to use, how long to warm up, non-divot turning techniques). Anything else I need to know? I assume that practice makes perfect and that my wobbly practice stripes on the demo unit will improve over time. Thanks in advance in a major way! I trust that these guys will give me a full education, as they are a 5 star dealer. The owner said to make sure I ask all my questions while the delivery guy is there in person to teach me, even though he is more than willing to take them piecemeal over the phone.
