Before You Start

These update instructions provide information on how to modify

performance, reliability and/or safety of the original equipment. A

detailed Operator’s Manual was supplied with the main unit when

it was purchased. Refer to the Operator’s Manual for information

on safety, operation, adjustment, troubleshooting, and mainte-

nance pertaining to this equipment (some of these sections do

not apply to all equipment).

General Information

These update instructions apply to the 2N-24 and 2N-30 Depth

Stops listed below:

196-189A 2SNT DEPTH STOP UPDATE KIT

Starting on page 4 is a detailed listing of parts included in these

kits. Use this list as a checklist to inventory parts received.

Instructions

The existing hydraulic depth stop valve is being upgraded. With

the new valve the coulter depth is adjusted by means of a knob

on the valve assembly (remove bushings before operation).

CAUTION!

Escaping ﬂuid under pressure can have sufﬁcient force to penetrate the

skin. Check all hydraulic lines and hoses before applying pressure.

Fluid escaping from a very small hole can be almost invisible. Use pa-

per or cardboard, not body parts, to check for suspected leaks. If in-

jured, seek medical assistance from a doctor that is familiar with this

type of injury. Foreign ﬂuids in the tissue must be surgically removed

within a few hours or gangrene will result.

NOTE: JIC ﬁttings do not require high torque. JIC and o-ring

ﬁttings do not require sealant. Always use liquid pipe sealant

when adding or replacing pipe thread ﬁttings. To avoid pos-

sible danger of cracking hydraulic ﬁttings from overtighten-

ing, do not use plastic sealant tape.

IMPORTANT: When using sealant on pipe threads the friction

between the threads is reduced; therefore, be certain not to over

tighten which may cause damage to a valve, cylinder port or ﬁt-

ting.

Disassembly of Existing Depth Stop

Refer to Figure 1:

With the drill attached to the tractor, unfold and lower the drill into

ﬁeld position and relieve the cylinder pressure on the ﬁeld lift cyl-

inders . Remove the hard line (#1) and disconnect the hose (#2)

from the rod end of the left hand cylinder which the depth stop

valve is attached to. Unpin and remove the cylinder (#3). Re-

move and discard parts 4 through 10 from the cylinder.

When you see this symbol, the subsequent instructions

and warnings are serious - follow without exception. Your

life and the lives of others depend on it!
