The cost of repairing a riding lawn mower can vary significantly based on the lawn model, type of work being done, and the lawn technician performing the repair. Generally speaking, lawn technicians charge anywhere between $50 to $200 per hour for labor. Also, depending on the lawn model, parts replacement costs can range from a few dollars to hundreds of dollars. Homeowners should compare multiple lawn technicians in their area and obtain quotes from each before making their decision as to who will perform the repair. Taking these steps can help ensure that lawn owners are getting competitive rates for the lawn work and ultimately save them money.
