Awesome Paul pics when you have them. These were the big things I noticed in the first few hours of tractor operation:
Be especially careful on any slopes. Tractors arent cars and they respond very differently.
Get used to wearing that seatbelt. It was actually harder for me on the tractor because I get on and off so much.
These machines are very strong. Anything you hit with them is going to get messed up...like corners of a barn, other things on the property. As mentioned you must go slow.
Lastly, if you have any implement on the back, remember the swing of said implement as you turn. The tractor has a tight turning radius, but that implement out the back will get you in trouble. Always be mindful of it when turning anywhere.
