What is unique is precision packing – packing where it counts. We use a spring loaded packer plate to pack a thin, firm layer of moist soil over the seed at the bottom of the furrow. In dry conditions, Technotill owners can choose to seed deeper into moisture and in wet conditions, the system does not over-pack. Technotill owners expect a high percentage of seeds to germinate quickly and evenly.
In heavy soils and wet conditions, the pack is set at ¼ inch. In other soils the pack can be set thicker, to a maximum of ½ inch. When seeding grass, the pack is set thinner than ¼ inch. The pack is clearly visible. In clay soil, it is as firm as the seedbed. In lighter soil, it is less firm, but still clearly visible.
The bottom of the packer plate is raised or lowered using a nut on a threaded rod. A jam nut secures the setting.
In most cases the packing pressure and pack thickness are set in the same operation. The spring is compressed between the upper and lower cast frame of the packer.
The uncompressed spring measures 7.25 inches. According to manufacturer’s specifications:
1/2 inches of compression = 70 pounds spring pressure
3/4 inches of compression = 90 pounds spring pressure.
The seed is placed at the bottom of the furrow on an "unfractured‟ moist seedbed. Technotill recommends that the seed be placed into the moisture layer so that moist soil will be packed over the seed. In limited moisture conditions, plan to seed slightly deeper to ensure enough moisture to support germination. In excellent moisture conditions, seed is generally placed 1- 1.5 inches deep.
The pack thickness remains the same at any seeding depth. As seeding depth increases, expect that more loose soil will fall over the pack. This can be controlled, to some extent, through speed.
Any heavy-duty air-seeder, floating hitch cultivator, or fixed hitch cultivator in good repair can be used. The tool bar must have a heavy-duty (minimum 1x2 inch) C-shank and heavy-duty (minimum 450 pound) trip mechanism.
Narrow furrow openers with front seed delivery are required, which allows the Technotill Precision Packer to be bolted to the rear of the shank. Please call Technotill to discuss the available choices.
A choice of packer plates is available. Packer plates with an additional tungsten carbide wear plate are expected to have similar wear to the carbide on the opener tip. A packer plate without the wear plate has been designed particularly for heavy clay soils, but is less durable in more abrasive soil.
A blend of “starter fertilizer” can be placed with the seed. Dry, liquid or NH3 fertilizer can be side-banded.
This varies, depending on soil test results, soil type, moisture conditions and the type of crop being seeded. We recommend that a blend of starter fertilizer be placed with the seed and additional fertilizer side-banded.
After the seedrow is packed, the fertilizer is sidebanded into the wall of the furrow. The fertilizer is placed the thickness of the pack higher than the seed, and approximately 1 ¼ to 1 1/2 inches from the seedrow.
In older models, a chain was used to break up dirt, straw and chaff lumps; provide a loosely packed, protective layer above the packed seed; and mix dry fertilizer with the loose soil in the seedrow.
The chain is no longer needed. Fertilizer is side-banded, straw and chaff management practices have improved, and the chain was found to be ineffective in light soil and wet conditions.
The most frequent spacing is 9-12 inches, with a minimum of 7.5 inches. Wider spacing reduces soil splashing from rear rows to front rows and provides more clearance in heavy residue conditions.
The Precision Packer works below the surface of the soil, which reduces some problems. Wider row spacing accommodates more trash. Proper straw and chaff management during harvest is important to ensure that residue is chopped and spread evenly across the field.
All Technotill products are warranteed for the first year. Parts that fail will be replaced. The Technotill Seeding System is made of steel alloy materials with heavy-duty fittings which have been found to stand up in abrasive conditions and stones. Technotill carries a stock of replacement parts.
In these conditions, Technotill recommends using a standard skid plate and a pack thickness no greater than ¼ inch.
Customer experience indicates very little problem with plugging.
The packer plate is the point of wear on the Technotill Seeding System, so easy replacement is important. A tungsten carbide wear plate brazed at the rear of the plate increases durability. A plate without the wear plate is available for heavy clay and gumbo soil. Experience has shown that this plate cleans more easily in very 'sticky' conditions.
Expect improved germination. Use the normal rate for cereals and pulses. Experience indicates that the seeding rate for canola is usually 4-5 pounds/acre.
The Technotill Seeding System requires approximately 3 to 5 horsepower per shank. This is about the same as a 16 inch shovel.
3 horsepower per shank accommodates normal seeding conditions. 5 horsepower per shank allows for seeding deeper in dry conditions or direct seeding into heavy sod.
Additional horsepower for the tank depends on tank size.
Yes. We recommend that fields should be rolled in the same direction as the seed rows. The roller rides on the hump between the seed row, and does not seem to compact additional soil over the seed row.
Technotill is designed to be a durable system, but it doesn’t last forever! In addition, Technotill has improved the design of a number of system components: the yellow bracket which attaches to the shank, position of the fertilizer sideband, the packer plates, and the shank bolts. These improvements have improved durability, ease of installation, and performance.
Check the following:
1. Wear on the packer plate. The plate should hang below the casting in which it is installed. If the packer plate is worn, the rear of the casting will be worn. In that situation, there is not proper packing of the seed row.
2. Wear at the orifice for the sideband. If the carbide wing is not intact, there will be significant wear on the casting, resulting in incorrect fertilizer placement.
3. Wear on the packer hinge bolt.
4. Wear on the opener. Check wear on the carbide tips, and the sides of the seedboot.
Very little maintenance is required, but to maintain performance, we recommend:
Annually, before seeding:
1. Check for wear on the packer plate, carbide wing in front of the fertilizer orifice, and wear on the packer hinge bolts, and roll pin.
2. Check for wear on the opener: condition of the carbide tip, wear on the sides of the tip and on the seed boot.
3. Check Speed Loc adapter to ensure that it is centred on the seed boot and that the bolts holding it to the seedboot are tight.
4. Check that the shank bolts are tight.
5. Check pack thickness and adjust to correct for wear on the packer plate, shank linkage, or seedboot tips.
1. In the field, check that the cultivator is level.
2. Periodically, check that the packer plates are intact, the hinge bolt is tight, and the roll pin is properly placed.
