Small Engine Advisor
Although the Small Engine Advisor is a commercial site for ordering parts (which is a great resource in itself), it has a wonderful array of free troubleshooting guides for small engines. We all have mowers and blowers and string trimmers, and this is a great place to find out what's wrong so you can try to fix it yourself or at least have an idea of what to tell the engine repair shop when you haul it in.

Leaf and Lawn Vacuum
Although mowers do a good job of shredding leaves for mulch, with a large wooded landscape it is incredibly time-consuming to manage leaves since they still have to be raked out of beds for the mower to reach them. The DR Premier Leaf and Lawn Vacuum solves the problem. This piece of equipment pulls behind the mower and vacuums up and shreds the leaves in one movement. It has a large storage container as well as a hose that you can attach when you need to vacuum leaves out of the beds. It has reduced our leaf management time by half, and has given us bushels of finely shredded leaves for mulch. For more info, visit: http://www.drpower.com/.
