IMPORTANT: Drain port back-pressure must be less than 172 kPa (1.72 bar) (25 psi) or fan motor damage occurs.

NOTE: If your John Deere tractor is not equipped with a low-pressure drain connection, order installation kit from your John Deere dealer. See LOW-PRESSURE DRAIN CONNECTION in this section for kit listing.

3. Tractor must be equipped with a low-pressure drain port (A) for connection of fan motor case drain. When operating with a John Deere 1810 or 1840 Seeding Tool, a second low-pressure drain port is needed for connection of depth control relief circuit. Instead of a low-pressure drain, depth control bleed-off hose can be attached to an open SCV, when one is available. This SCV must be placed in "Float" position when operating.

CAUTION: Make sure tractor master shield (A) is in place at all times, to prevent entanglement with rotating PTO shaft. Coming in contact with a rotating PTO shaft can cause severe injury or death.

4. Consult tractor operator's manual for specific adjustment procedures, tire inflation, wheel spacing, and ballast requirements.
