housing should be adjusted so that the front
is approximately 1/8" to 1/2" lower than the
rear when the mower is in its highest position.

ments, check that both front links are
equal in length.
• If links are not equal in length, adjust
one link to same length as other link.

both front links an equal number of turns.

lower at front than rear, tighten nuts “F”
against trunnion on both front links.
