Abstract

ABSTRACT

A mower having a belt tensioner that includes a belt engaging primary pulley swingably supported by a primary arm.
A rod coupled to the arm carries a spring that acts to push the pulley into engagement with the belt. The rod acts to pull the pulley away from the belt to release the tension in the belt for removal of the belt. A handle attached to the rod is turned by the operator to positively swing the pulley away from the belt. The handle may also be gripped by the operator's hand to lift that portion of the deck during operation to avoid gouging irregular ground conditions or striking obstructions.
