Ariens Company has discovered that push nuts used in the manufacture of air ride seats p/n 04383700 may
not have been properly seated. In some cases, improperly seated push nuts have come off, allowing control
arms attached to the air-spring saddle to come loose leading to the saddle bending and damaging the air-
spring bellows.
Dealers are to inspect all unsold inventory in the model and serial number range listed above and correct if
necessary.
1. Check the Milsco serial number of the seat on an affected unit. If the serial number of the seat is
above 53-798950 then it is not necessary to do any further inspection.
