Folding Marker Breakaway
Refer to Figure 33
The marker arm has a pivot at the hinge which is
connected rigid with a 5/16 inch bolt (1). The shear bolt
will break if excessive force is put on marker during
operation allowing marker arm to swing away rather
than cause damage to the marker.
Note: The shear bolt is a 5/16 x 1 1/2 inch grade 5 bolt
and is identified by three markings on the head,
see page 53. It must be replaced by an equivalent
grade 5 bolt to prevent marker damage.
Storage
Store the drill where children do not play. If possible,
store the drill inside for longer life.
1. Unload seed box.
2. Thoroughly clean seed and seed-treatment residue
from boxes and feed cups.
3. Remove any dirt and debris that can hold moisture
and cause corrosion.
4. Lubricate and adjust all roller chains.
5. Take special care to oil feed cup drive sprocket in its
square bore.
6. Lubricate areas noted under “Lubrication”, page 45.
7. Inspect drill for worn or damaged parts. Make repairs
and service during the off season.
8. Use spray paint to cover scratches, chips and worn
areas on the drill to protect the metal.
9. Disconnect seed hoses from openers. Permanent
elongation and premature cracking of hoses may
occur if stored connected.
10. Cover with a tarp if stored outside.
