14
Some tillage implements have close to 180 degrees of wing travel into transport position. Machines like this include
short wing machines with low transport height and 5 section machines (outside wings only). This type of fold
can cause interference problems with SMC Mounted Harrows. The following are steps to prevent problems:
MODEL 74:
1. If mounting brackets/arms hit in transport position, one of the 2 interfering brackets/arms must be moved.
2. If sections hit in transport position, limit travel of top section by:
a. Slide and secure lock collar down support rod a maximum of 3”.
or
b. Replace standard 8H1308 pressure spring with 8H1306.
or
c. Add third mounting arm assembly.
MODEL 94 through 106:
1. If mounting brackets/arms hit in transport position, one of the 2 interfering brackets/arms must be moved.
2. If sections hit in transport position, limit travel of top section by:
a. Slide and secure lock collar down support rod a maximum of 2.5”.
or
b. Add second mounting arm assembly.
or
c. Install travel limit 1/2” x 5” stop bolts* (8X0073) in mounting brackets (8H2120). Secure stop bolt
with 1/2” lock nuts (8X0242), do not over tighten, mounting arm MUST be free to rotate on pivot bolt.
*Stop bolts should be used as a last resort. Extensive frame damage could occur if stop bolts are incorrectly
installed or if eld obstruction causes mounted harrow section to exceed travel limit.
ALWAYS raise machine slowly into transport position the rst time after installing Mounted Harrows, watch for
interference and make adjustments as required.
