Chain Tension. The seed meter drive has a
spring-loaded idler which requires no adjusting.
However, chain stretch may make it necessary to
shorten the chain.
Refer to Figure 65
For best chain tension the recommended vertical
distance between chain idlers should be not less
than 1/4 inch and not more than 1/2 inch. This
measurement should be taken with opener arms
horizontal.
Refer to Figure 66
NOTE: The front idler should be below the rear
idler. Be sure chain is installed with the chain
connector link retainer towards the centerline
of the opener and the clip opening (spit end)
faces the opposite way of the chain travel.
