Toro TimeMaster 30" (Model 21199 / 20199)
2012–Present 30-inch dual-blade wide-area commercial/residential walk-behind mower with Personal Pace self-propel and BBC.
Quick-Glance Shop Specs
Full Matrix ↓The dual-blade timing belt jumps teeth when striking roots or irrigation heads. If the engine bogs instantly upon engaging the BBC (blade brake clutch) or vibrates violently, remove the plastic deck top cover immediately—do not run the blades timed out 90 degrees or they will impact each other and bend the spindles.
