Features
Fertilizer placement
Dry high top fertilizer knife 
Each easily-adjustable opener places fertilizer 2-in. to 6-in. deep, giving precise placement so the crop is being fed, not the weeds.
Independent opener force can be set between 200 lb to 500 lb with a trip clearance of 12 in. to meet seeding conditions. The adjustable breakout force is extremely important for seeding in rocky conditions.
So, whether using dry, liquid, or anhydrous ammonia, the John Deere ConservaPak⢠opener has the options that fit the application needs.
High-top liquid fertilizer knife (code 1215) 
Liquid tube holder (code 1215) The optional liquid fertilizer tip features 1/4-in. stainless-steel delivery tubes.
High-top liquid and dry dual delivery (code 1220) 
Dry tube (code 1220) The optional combination liquid fertilizer tip features 1/4-in. stainless-steel delivery tubes. The dry tube will mount on the shank to give operators the ability to use a liquid/dry combination.
High-top mud-proof dry fertilizer (code 1235) 
The mud-proof combination: dry-fertilizer tube and tip, code 1235, is available for those applying dry fertilizers only. This is recommended for running in sticky, heavy clay-type soils. However, it works well in all soil types to prevent mud from plugging the fertilizer tube opening. This opener is included as base equipment.
If seeding with dry fertilizer only, this option is highly recommended. The fertilizer exits the tube at a lower point, allowing growers desiring to place fertilizer at shallower depths more consistently.
The lower fertilizer exit point also allows the fertilizer to get to the bottom of the trench when more fertilizer and seed separation is desired, and for those light soils that tend to cave in the trench before the fertilizer is placed.
Dry high-top knife (available through parts) 
Dry tube (available through parts) If operating in extreme, abrasive soil conditions, high-top knives are available. The high-top design adds carbide on the entire face of the knife, and also adds extra hard steel above the knife itself, which provides additional protection for the shank.
Anhydrous high-top tip (code 1250) Dry tube The high-top anhydrous ammonia (NH3) features a 1/2-in. outside diameter (OD) steel delivery tube, and features the high-top for added wear resistance. The NH3 knives may also be used in combination with the included dry-delivery tube for those wanting to apply NH3 and dry fertilizers simultaneously in the same fertilizer trench.
Aqua anhydrous (code 1255) Dry tube The NH3 tip is also available for those utilizing aqua-anhydrous ammonia systems with 3/8-in. NH3- delivery tubes and dry-delivery tubes.
Dry knife (available through parts) Dry tube (available through parts) The standard dry knife features carbide tiles on the face to provide a long wear life. The standard knife is paired up with the 1.25-in. dry-delivery tube to provide accurate dry fertilizer placement. If seeding with dry fertilizer only, the mud proof combination is highly recommend, as seen below.

Agronomic benefits
Implementing moisture conservation farming practices
From the start, the ConservaPak⢠opener was designed with agronomically friendly farming practices in mind. From the precise seed and fertilizer placement to the minimal tillage disturbance system, the John Deere 1870 optimizes farming operations.
Hydraulic shanks are the workhorses of the 1870 air-seeding tools. They provide consistent depth control for enhanced seed placement, resulting in more even emergence and more uniform crop maturity at harvest. The hydraulic shank seeding tool uses a rigid frame for strength and support. The openers are designed to allow independent downforce for a more uniform depth across the entire width of the frame.
Seed and fertilizer separation are not compromised when seeding with the 1870. The ConservaPak design allows for banding fertilizer to 6 in. within the seedbed and up to 4.5 in. of separation between the seed and fertilizer. The deep fertilizer opener doubles as a tillage tool to shatter the hard pan for improved root development, water infiltration, and seedbed warmth.
