The soil probe helps operators to determine the proper operating depth of their ripper points,
38 mm (1.5 in.) below the bottom of the compaction layer.
The probe allows obtaining the maximum amount of soil fracturing from the entire family of John Deere ripper points. Marked in 51-mm (2-in.) increments from 254 mm to 559 mm (10 in. to 22 in.), the probe provides accurate feedback of compaction layer depth.
It is stored on the mainframe of the ripper for convenient access. The operator's manual explains the proper use of the soil probe.
