Abstract
A quick-adjusting jackstand apparatus is particularly useful on any harvesting attachments. An improved jackstand has a coarse adjustment and a fine adjustment. Coarse adjustment is accomplished by moving the jackstand from a first stored position to a second extended position. A secondary fine adjustment is accomplished by rotating an inner member which is housed in and threadedly engaged with an outer member. Such rotation results in extension of the inner member from the outer member. The threaded engagement of the members is protected from excessive clogging because such threaded engagement is within the outer member.
