Opener Frame Down-Force
Crushing Hazard:
Always stop tractor engine, set parking brake, and remove key
before adjusting or servicing openers. You will be seriously
injured or killed if you are caught between raising openers and
drill frame. Keep all bystanders well away during drill
operation.
Hydraulic opener down pressure controls drill-wide
opener penetration and press-wheel soil firming. Use
only enough down pressure to cut a furrow and maintain
proper soil-firming over seed. Excessive opener down
force may cause bulldozing of the openers in light soil
conditions, and leads to premature wear on opener
components.
The table at right shows the approximate force at
openers for a given pressure at the pressure control
valve.
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Check all hydraulic lines and fittings before applying
pressure. Relieve pressure before disconnecting hydraulic
lines. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. Fluid escaping from a
very small hole can be almost invisible. Use paper or
cardboard, NOT BODY PARTS, to check for leaks. Escaping
fluid under pressure can have sufficient pressure to penetrate
the skin causing serious injury. If hydraulic fluid is injected
into the skin or eyes, seek immediate medical assistance from
a physician familiar with this type of injury. Within a few
hours gangrene can start to develop. DO NOT DELAY.
