It is hard to put a finite number on how long the product will last because there are a lot of variables to consider such as cumulative run time, turf conditions, and maintenance. If you are using a residential TimeCutter product for a commercial business, rather than a commercial product (like the Z Master) you could expect that the life of the product would be shorter. Performing regular maintenance on the product will help to ensure that you get the most out of the unit. All of the components are quality tested before they are used on the machines so that we are confident that we are providing consumers with the best possible product.
