meanjean, isn't it funny how steep the learning curve is when using a tractor for the first time? Boy does it come fast. Sounds like you already knew what you needed to do but just needed a little reassurance.
I do feel bad for you when you used the wheel barrel to take the place of the tractor. I bet that was very discouraging for you. We have all been in that situation but with different tasks and can't help but feel kinda let down by the little orange giant.
Keep your positive attitude and just come to terms with what the Kubota is capable of and you will never be disappointed.
When you get the scraper please post some pic's of your new toy, I'm sure she's a beauty!
