Spring loaded wheel and shaft prevents wheel travel and the oversized shaft prevents flex and premature bearing failure. An optional cross support brace can be added for additional rigidity. Please don't hesitate to watch out blower comparison video and feel free to reach out to us with any questions on installation or fitment.
Please consult the compatibility guide below to ensure fitment. This blower is constructed of high grade materials and is engineered to operate smoothly, efficiently and last a long time. Blower comes with a 1 year replacement warranty.
Please note: power cords and blower chassis diagonal support braces are NOT included with replacement blowers.

Replacement blowers are intended to replace worn or defective blowers and do not include the components of a full blower kit. This blower may be used as a universal replacement blower, so please review dimensions before purchasing.
