Normally, when one of your workers uses the skid steer on the construction site, they can easily start the equipment by turning the ignition key. However, they may have reported lately that they are having difficulty getting the engine to turn over.
Eventually, they may have to spend several minutes to get the skid steer to start, or it may refuse to start at all, which could mean that the starter is going bad.
Do you have an old car that broke down and isn't worth fixing just sitting in your yard? Did you get a project car with the goal of repairing it, only to have it gather cobwebs in the yard? Or did someone move out and leave behind a non-operable vehicle that's now your problem? If you answered yes to one of these questions, you should consider selling that junk car for cash.
