Extended reliability and durability testing of the new 520
single stage snowthrowers indicates that the life of the
auger drive system is significantly improved by doubling
the material used in the auger center section.
Based on these test results, we have added a second
center section to the auger, and a support strap to the
auger housing on all units produced during and after
October 1997.
Because the auger drive performance is significantly
improved by these enhancements, we desire to have
ALL units updated to include these enhancements.
Please update all units in your stock, and contact all
customers to whom you have delivered a 520 or Snow
Tackler (They may bring the unit in for you to update, or
they may perform the update themselves — it is a simple
15 minute procedure.)
And remember to inform your customers that these
double center sections can be reversed to extend drive
life even further.
