Description
This Used John Deere 680 Series Drawn Chisel Plow Operators Manual is the essential guide for owners and operators of the John Deere 680 Series Drawn Chisel Plow. This manual covers operation, safety, service, and maintenance to help ensure reliable performance in field conditions. Issue J8. Copyright 1998.
Whether you are setting up for the season or troubleshooting mid-use, the manual includes detailed instructions on safety signs, preparing the tractor (including hydraulic system setup for 55/60, 7000, 8000, and 9000 Series tractors), securing hitches, and careful attachment & detachment. It walks you through transport procedures, depth control operation (including TOUCHSET™ systems), wing and frame leveling, adjusting depth, replacing tools, lubrication schedules, and bolt torques.
One of the most common repair needs on these machines arises from depth control issues — springs, wear of hydraulic control parts, or misadjusted folding wings. This manual gives precise guidance for diagnosing and correcting depth inconsistency, hydraulic leaks, or problems with wing fold mechanisms.
Also included are diagrams of standard spacing for rigid, spring-reset, and flex fold configurations; specifications such as tractor horsepower requirements; and instructions for preparing the machine for storage or seasonal downtime.
