Why won't my zero turn go forward or reverse?

If your zero turn mower won't go forward or reverse, it may be due to a few common issues. First, check the safety features, such as ensuring the operator presence switch is engaged and that the parking brake is released. Additionally, inspect the drive belts for damage or wear, as well as the hydraulic system for any leaks or low fluid levels. If these components seem fine, the issue may lie in the transmission or control linkage, which may require professional attention.
