Down pressure shocks for Deere, Kinze planters
New from Black Machine Mfg., Vinton, Iowa, is an air "down pressure" system for Deere and Kinze planters that uses regular air shocks the same type used on passenger cars to apply extra strength for cutting through heavy trash.
On each row unit, the standard heavy-duty springs are replaced with an air-operated shock and mounting bracket. The advantages:
-One adjustment sets down pressure for all row units.
•All row units automatically receive and hold the exact same pressure (up to 150 psi).
Once installed, the system is charged with air to provide the desired "down pressure". It can be recharged, as needed, with air from a portable air tank. For field situations requiring frequent changes in the amount of down pressure applied, an optional, planter-mounted battery-powered air compressor is available. It allows you to change the amount of down pressure for all row units "on the go" right from the tractor seat. One switch turns the compressor on to add air to increase down pressure. A second switch (Schrader valve) bleeds air to reduce down pressure.
The system is currently available for Deere 7000, MaxEmerge, MaxEmerge II (including vacuum) and Kinze planters. Air shocks, mounting brackets and air hoses sell for $130 per row. The optional air compressor sells for $205.
