Three reasons the F15/F15B is ideal for fall fieldwork


As all farmers know, there’s no rest after harvest—as soon as the crops are in, it’s time to prep seedbeds for the next planting season. Fall fieldwork is key to generating good emergence and yield, so it’s important to get it right. Here’s a few reasons why AMCO’s F15/F15B Double Offset Tandem Disc Harrow is the perfect tool for the job:

  1. The F15/F15B breaks up soil compaction. Folding flexwings follow the ground contour, while the unit’s double offset tandem design smooths the soil. This action breaks up compaction caused by heavy combines and other equipment, setting you up for the perfect seedbed.
  2. The F15/F15B manages residue. Overlapping front discs cut through tough residue, evenly incorporating it into the soil where it can break down and release nutrients. As an added bonus, breaking up residue also promotes accurate seed placement, since un-decomposed residue can interfere with seed drills in the spring.
  3. The F15/F15B incorporates chemicals. Fall is the time to promote the health of your field, whether that means applying fertilizer to supplement nutrient deficiencies or herbicides to control weeds. The same overlapping discs that cut through residue also incorporate chemicals.

Did you know? The F15/F15B now features PEER® Maintenance-Free Bearings. Like the Protect-O-Shield® Bearings AMCO has used in the past, these bearings are triple-lip sealed and feature a protective shield that covers both sides of the bearing to defend against dirt and debris. Because the bearing is trunnion-mounted and maintenance-free, there is no need for daily lubrication.

Upgraded AMCO bearings add 25 acres per day to productivity


PEER Maintenance-Free Bearing

When you’re working in the field, productivity takes a hit every time you have to stop to replace a clogged disc bearing. Add that to your time in the shop relubricating, and you could be running into an efficiency problem.

But there’s no way around it. Bearing maintenance is just part of the job … isn’t it?

Not necessarily. AMCO has upgraded to PEER® Maintenance-Free Bearings. They feature the same design as the Protect-O-Shield® Bearings AMCO has employed in the past—triple-lip sealed, with a protective shield that covers both sides of the bearing to defend against dirt and debris. The difference is the bearing itself, which is trunnion-mounted and maintenance-free. With this bearing in place, daily lubrication becomes a thing of the past.

“It’s a highly durable bearing that growers don’t have to invest in maintaining,” said AMCO Marketing Manager Michael Atwood. “Growers can expect to work up to 25 more acres per day with the time they save. Plus, they won’t have to constantly purchase grease to keep bearings lubricated.”

The maintenance-free bearings are housed in high-strength ductile iron and have a longer life than their predecessors. They are interchangeable with existing mounting patterns and compatible with both Rigid and Shock Absorber Bearing Risers.

Keep your crops above water with raised soil beds


In the Ag business, rain is a blessing … until it isn’t. Across the country, we’ve had a pretty soggy summer and fall. Some areas have gotten nearly three times their average rainfall.1

So, what can we growers do to keep our crops from drowning?

One tried-and-true solution is raised soil beds.

Benefits of raised soil beds

Raised soil beds are typically built using tools like AMCO’s High-Clearance Bedding Hipper Assemblies. Construction happens in the fall after harvest or in the spring before planting. The basic idea is to boost plants up out of the water, which can lead to better growth and yields. For example, researchers found raised beds had a 17.7-bushel advantage over flat ground in a 2007 study at Mississippi State University.2

The benefits of raised beds don’t end there. They can also improve irrigation in your fields, since water is able to flow freely between the rows. Soil is also able to dry faster and retain moisture better. Finally, weeds like ryegrass don’t like growing in raised beds, which means easier weed control.

Fall or spring?

Whether you build your raised beds in the fall or spring varies by region and soil type. Many growers who plant in heavier soil, like mixed clay, build beds in the fall so they’re ready for spring planting. When spring arrives, they just knock off the top ridge of the beds with the hipper and plant into them. But farmers who plant in softer soil often opt to build beds in the spring so the beds don’t degrade over the winter (and to avoid a time crunch during harvest).

8-ROW_ISO-Staggered-OpposedConstructing raised beds

  • Operate the bedding hipper at 5 to 8 mph.
  • Don’t run the hipper any deeper than necessary. High speeds and shallow depths create uniform beds, while low speeds and deep depth settings may cause bulldozing in front of the hipper’s gangs.
  • Always vary the gang angle to suit your ground conditions. Staggered gangs work well in most soil conditions and layer soil into smooth, slightly rounded beds. Opposed gangs make higher, pointed beds and operate well at high speeds, but they clog more easily in heavy, moist soil or fields with lots of trash.

But the real key to constructing solid raised soil beds is using the right tool. AMCO’s High-Clearance Bedding Hipper Assemblies offer top-level performance in high-residue conditions, as well as trouble-free seedbed preparation. Features include:

  • Blade sizes from 16″ to 24″; choose from smooth or cutout blades
  • 1½” square axles and Protect-O-Shield® Bearings to eliminate blown seals and prevent wrap damage; backed by our exclusive two-year warranty; each housing features two bearings for added durability
  • 6-, 8-, 10-, 12-, and 16-row assemblies

Did you know? Because raised beds let soil dry faster, you can plant sooner in wet years, which leads to faster crop emergence. On the other hand, raised beds also help soil retain moisture. In a dry spring, farmers just drag more off the top of the bed to get the needed moisture for planting.



Top four benefits of the AMCO Terracing Plow


For growers who live in regions with a lot of precipitation, terracing is critical for preventing erosion and conserving water and soil. In fact, it’s such an important practice that AMCO designed a plow specifically for terracing—the only one of its kind on the market.

But what is it that makes this unique plow stand out? Why is it a better investment than traditional terracing equipment, like bulldozers and scrapers?

Here’s a list of the top four benefits of using the AMCO Terracing Plow:

  1. Speed. The Terracing Plow is capable of building 1,000 feet of terraces or more per hour, which is significantly faster than using a bulldozer or other types of heavy construction equipment.
  2. Integration. Though the Terracing Plow design is unique to AMCO, it’s easy to integrate and operate with existing equipment. This saves both time and money you might otherwise invest in hiring workers to bring in bulldozers, scrapers, and other big pieces of earth-moving equipment.
  3. Versatility. The Terracing Plow can handle both narrow-base and broad-base terrace construction, building and packing the terrace with multiple trips through the field. It can also easily refurbish older terraces.
  4. Sustainability. The Terracing Plow operates within Soil Conservation Service (SCS) specifications, which help conserve soil moisture, provide erosion control, and reduce airborne particulates.

When building a terrace, you need durable, high-quality equipment that can get the job done. Not only is the AMCO Terracing Plow the sole plow on the market specifically designed for building and refurbishing terraces—its speed, ease of use, versatility, and sustainability provide a better return on investment than traditional terracing equipment.

To learn more about the Terracing Plow, check out the list of features below or contact our team of tough tillage experts.

Did you know?  When breaking ground on a terrace, you’ll get the best results if you keep your tractor speed at or above five miles per hour. Faster speeds reduce construction time by boosting upward and inward movement of soil on the terrace. For more tips, read our step-by-step guide to terrace construction.

The right small disc can still pack a big punch

Ask a group of farmers what they like to see in their equipment, and you’ll likely to hear two things: versatility and durability.

Sure, we expect to see these qualities in large disc harrows…but what about smaller models? Are there any small discs on the market that pack a big punch?

You bet! AMCO’s 3-point discs are built to be just as tough and flexible as our large harrows. Because of their compact design, our smaller discs can handle any job you throw at them. Because of their durability, they can overcome the toughest operating conditions.
