CHAIN IDLER SPROCKET ADJUSTMENT
(See Figure 8)
The chain idler sprockets (one per side - located under the side chain guards) can be adjusted to remove
excess slack in the chain caused by normal chain wear or stretch. Before adjusting idler sprocket position,
ensure that the chain and all sprockets have been cleaned and that the chain seats properly on the
sprockets. A build-up of dirt on the sprockets or chain can cause the chain to become too tight. Inspect all
the sprockets, bearings, and the chain for wear or damage.
With the tine reel elevated, loosen the idler sprocket and move along the slot to adjust to the proper
tension setting. Chain should have a up and down movement of 1/2” inch to 3/4” inch (12 mm to 19 mm).
Take measurement above the idler sprocket, see figure 8. Retighten idler sprocket and recheck tension
setting measurement. Set both sides the same.
If the chains cannot be adjusted within the movement of the idler sprocket, the chain can be shortened by
removing a half link. Each chain has two half (offset) links. Remove one (or both) half links. The shortened
chain will reposition the idler in the slot allowing for extra adjustment. Both chains should be the same.
