Ariens Company has identified a potential safety concern on models and serials listed in the table below.

The auger drive pulley, #00268951, may develop a crack which could affect the brake's ability to stop the

auger/impeller, resulting in an unsafe condition.

Dealers are instructed to Stop Sale Immediately of any unsold inventory which falls into the model and

serial ranges listed. Additionally, dealers are asked to contact consumers who purchased affected

machines from your dealership to coordinate repair of those machines as soon as possible. Ariens

Company is sending a letter to registered owners of all affected machines alerting them to this situation.

Ariens Company has been reworking product since this issue was identified, and all machines which have

been reworked by Ariens Company will have a black check mark on the carton label as well as the model/

serial label on the machine.

Dealers are asked to order kit #52001800 and install it on each affected unit. The kit consists of a

replacement pulley and hub assembly. Dealers should file a warranty claim for each pulley replacement

using a flat rate code of 20999. Please make sure that the machine is within the model/serial numbers

listed below. Warranty claims will be reimbursed for 0.50 at the dealer's standard shop labor rate.
