Did you have to run wire across the driveway? I was going to try this same set up but worried that the blades might be going when crossing concrete and be a problem.
This model is the 550X which is the commercial model, the 450X is the residential version. The difference between the two modes is the the 550 does not have headlights and it does not have a LED screen built in. The 450 has these features.
