Select the Spot-Spitter model that suits your application. For flow rate information and number of Spot-SpitterS per lateral, refer to the online design tool.


a. Determine the length of tubing required to reach from the hose lateral to the desired location of the Spot-Spitter. Length should be long enough to allow for thermal expansion and contraction of laterals, but should not exceed 5 feet.

Figure 1
Cut one end (insertion end) at a 45º angle and the opposite end (spitter end) at a square 90º angle. (Figure 1) Confirm that both cuts are clean to ensure a water-tight fit. A clean 45º cut facilitates insertion and reduces the chance of tube blockage if inserted too deeply. A clean 90º cut ensures a proper flow pattern when fitted to the spray tip.

Figure 2
Using a John Deere hole punch, create a hole in the lateral hose by pushing and twisting the punch into the hose. (Figure 2) The hole punch has been specially designed to quickly create a large, clean hole that contracts within moments to create a leak-proof seal around inserted tubing.

Figure 3
Immediately after punching, insert the angled insertion end (see step 2b) of the tubing into the hole. Push until the angled end penetrates to about one third the diameter of the hose. (Figure 3) No glue or fittings are needed. IMPORTANT: the angled insertion end of the tubing must not touch the opposite side of the hose, as this may block flow.

To install an standard Spot-Spitter: insert the spray tip of the Spot-Spitter into the square-cut 90º end (spitter end) of the tubing. (Figure 4) Twist while pushing the tubing until its end passes the barb-ring on the spray tip. Do NOT push the tubing end past the stop-step. Twist the Spot-Spitter until the directional indicator nub (flat surface on Spot-Spitter SHORT) faces the desired direction, and push the base of the Spot-Spitter into the soil to the desired depth.

a. To shut off any Spot-Spitter model, simply remove the spray tip from the tubing, flip the Spot-Spitter and insert the shut-off tip.
b. To repair a hole in a John Deere lateral hose (or when tubing must be moved), you can create a water-tight seal by simply inserting a Goof Plug into the hole.
c. To remove obstructions from any Spot-Spitter model, simply remove the spray tip to flush out any debris.
• The information presented here does NOT constitute a system design and should not be used as such; it is a guideline for installation only. Consult an irrigation system designer or engineer for a complete system design.

• Use only John Deere polyethylene tubing (0.125 I.D. X 0.187 O.D.) and John Deere polyethylene hose. See the John Deere Hose and Tubing data sheet for specifications.

• Filtration requirements are a function of water quality and emitter size. Standard Spot-Spitters require only 50 mesh filtration; mini-flow Spot-SpitterS require 150 mesh.

• Pressure regulators may be needed to meet system requirements and to comply with the John Deere hose and tubing warranty. The recommended operating pressure for Spot-SpitterS is 15 PSI; the maximum operating pressure should not exceed 25 PSI.
