Ariens 21547853 Blade Adapter

Product Description

This is a Blade Adapter. Manufactured by Ariens. Blade adapters are designed in strict accordance with federal safety guidelines. They must be weaker than the cutting blades and yet strong enough to withstand the engines normal speed and resulting blade torque and vibration. When a mower hits a stationary object at 3,000+ RPM, the forces exerted on the blade and associated parts can be quite considerable. Sometimes a series of lesser impacts eventually results in enough vibration and combined stress that the blade adapter finally fatigues and fails. Broken blade adapters are most frequently the result of one or more of the following:

• The mower blade hitting a stationary object resulting in significant torque or vibration to the adapter and possibly also transferred through to the engine crankshaft.
• The mower blade being unbalanced, damaged or from the use of an unapproved cutting blade.
• The engine or engine crankshaft being damaged and thus resulting in excess vibration being transferred to the blade adapter.

All of which may result in excess vibration and subsequent blade adapter failure.

If you need reassurance in verifying that this Blade Adapter will fit your mower please don’t hesitate to call or email us. Be sure to have your model and serial number available.
