(A) should be between marks (G) on spring tension
bracket (B) for correct belt tension.
2. Turn belt tension handle (C) to move trunnion for-
ward or rearward until it is between marks.
3. If trunnion cannot be placed between marks, loosen
capscrew (D) and reposition idler pulley (E) as nec-

lar to the hitch. Retighten capscrew (D) and repeat
