Cornhusker State Newbie

Hello from Omaha. I have come across the forum in the past and didn't have need of the expertise of members until recently. I've been running a Toro Wheel Horse model 265 h garden tractor to cut grass and do some light hauling in my yard here in town. I am not mechanically inclined but can figure out some basic stuff. I should probably have the yard professionally mowed like the neighbors do but I enjoy the time I spend doing it. I am an owner of an advertising firm here in town and am slowly stepping out of the business but don't plan to start a new career as a tractor mechanic. That's why I need your help.
