As AMCO’s most massive tool, the G2 Wheel Offset Harrow is famous for its primary tillage performance in tough conditions. But did you know the same features that make the G2 a force to be reckoned with during planting also make it an asset in the construction industry?
“In construction, equipment has to stand up to repeated heavy-duty use, impacts, moisture, sunlight, and weather,” said AMCO Marketing Manager Michael Atwood. “The G2 has gained a reputation as a rugged harrow that can handle these demands.”
The G2 is specifically designed to take on challenging jobs, like working ground that has never been broken before or operating in heavily wooded conditions. Dual spring stabilizers keep the G2 level in changing ground conditions and help the harrow absorb rough terrain.
Weighing in at an impressive 10,179-18,342 lbs., the G2 is equipped with 36″ x ½” cutout blades. It offers a maximum cutting depth of 18 inches and cutting widths of up 20 feet. This gives the G2 has the power to get down to the root system and move significantly more dirt than other products on the market, making it the ideal harrow for clearing away vegetation.
To handle the 379-550 lbs. of force per blade exerted by the G2, AMCO partnered with a local manufacturer to design an oversized hydraulic cylinder with a special clevis that lifts the harrow into transport position on dual wheels.
“The G2’s scraper is another major advantage,” said Atwood. “It’s a welded system with a curved moldboard, which keeps the blade free of debris when you’re cutting through trash, mixing, aerating, and leveling soil.”
In addition to the scraper, the G2 has several other features that protect it from rough terrain, weather, and harsh impacts. The harrow’s powder-coat finish is more than twice as durable as a wet-paint finish, protecting it from scrapes, abrasions, and flaking. The G2 is also equipped with 2¾” triple-lip sealed Protect-O-Shield® bearings, which eliminate blown seals and prevent wrap damage. Safety features include a transporting lockout, safety chains, a slow-moving placard, and light kits.
“The G2 Wheel Offset Harrow gets the job done,” said Atwood. “It’s an asset on any construction site, whether you’re breaking up road beds, clearing underbrush, or breaking new ground.”

When you’re out in the field, nothing slows you down like having to replace a bearing clogged with dirt, stubble, and debris. To keep you moving, AMCO fortifies the following equipment with our industry-leading Protect-O-Shield® Bearings:
Protect-O-Shield Bearings are extremely durable; their design virtually eliminates blown seals and wrap damage. For starters, the triple-lip seals lock in grease to keep the bearings properly lubricated. The bearing also holds the seal securely in place during lubrication, preventing pressure from the grease gun from causing a blowout.
But the real secret is our protective shield, which provides an extra layer of defense against dirt and debris. The protective shield covers both sides of the bearing. Any material your equipment kicks up while moving through the field is blocked from damaging or getting stuck in your bearings, allowing you to cover more acres and spend less time replacing clogged or damaged bearings.
“The Protect-O-Shield Bearing is designed to be over-greased to purge out dirt and debris, which will help increase the life of the bearing,” said AMCO Marketing Manager Michael Atwood.
AMCO Protect-O-Shield Bearings are guaranteed for two full years. They should be re-lubricated with appropriate conforming grease after each use and at the end of the season. During lubrication, the bearing should purge new grease and then be rotated to ensure the cavity is completely filled.

Disc cutting depth has a major impact on overall crop yield. Cutting too shallow may lead to weak root systems, varying soil temperatures, and uneven emergence. Cutting too deeply puts unnecessary strain on equipment.
But setting and maintaining the ideal cutting depth is a delicate balance. To help you master it, AMCO has created this list of five key factors you need to consider while setting up and operating your disc.
When setting your disc’s tillage depth, the first thing to consider is blade diameter. Over the years, AMCO’s tough tillage experts have found that the ideal cutting depth in normal operating conditions is approximately 25% of the blade diameter. For example, for a 32″ blade, the cutting depth is about 8″. But for a 26″ blade, the cutting depth is about 6.5″.
Once you’ve calculated optimal tillage depth, set your disc to that depth using the depth controls.
Weight per blade
While it may be tempting to jump right into the field after setting the tillage depth, other factors must be taken into consideration. For example, the more weight a blade carries, the deeper it will cut—no matter the diameter.
Weight per blade is calculated by dividing the weight of the disc by the number of blades. Make a short test pass in an area similar to where you’ll be tilling and measure the depth of the blade furrow. If the furrow is deeper than one quarter of the blade diameter, there is too much weight on the blade. Relieve the pressure by reducing the tillage depth using the depth controls. If it’s too shallow, increase the pressure by increasing the tillage depth.
Like weight per blade, blade angle effects tillage depth. Specifically, setting the blades at a sharp angle increases blade penetration, while a shallow angle decreases penetration.
As you make adjustments to factor in weight per blade, also consider adjusting the blade angle. Keep making adjustments and performing test passes until the disc furrow measures one quarter of the blade diameter.
Even if your disc is locked in to all the right settings, field and operating conditions can impact your disc’s cutting depth. For example, operating a disc too fast or too slow prevents it from penetrating the soil at the correct depth. The disc won’t be able to effectively break up and toss the soil, which leads to shallow cuts.
In most conditions, the optimal operating speed is approximately 4–6 miles per hour. In sandier soils, discs can be operated up to 8 miles per hour. If you are unsure what the right speed is for your soil conditions, make a few test passes at different speeds and measure the furrow depth.
Like speed, soil conditions can have a major effect on tillage depth. In sandy soil, the disc may sink and cause the blades to cut too deeply. Tough, chunky “gumbo” soil might keep your disc from getting the correct penetration. If that’s the case, extra passes might be required.
As you make test passes during the set-up phase, you should get a good feel for the soil condition you’ll be working in, and you can make the proper adjustments. Just make sure to keep an eye out for changing soil conditions as you till–if you sense a change, check the depth of your furrows and make adjustments if necessary.
Getting your disc to cut at the correct depth often requires set-up time, but it’s well worth it when you achieve good yields and a return on your investment. To learn more about setting and operating your disc at the right tillage depth, contact our tough tillage experts today.
Did you know? A disc will incorporate residue into the ground roughly as deep as half the cutting depth. To break dirt clods most effectively, your second pass through the field should not be on the same angle as the first pass. Instead, enter the field anywhere from 30° to 90° off the angle of the first pass; this will help reduce streaks in the residue and provide a smoother soil finish.
This month, rice-planting season is in full swing across the United States.
Rice is unique because of the irrigated conditions it’s grown in. For your rice to thrive, you need a well-built levee that produces just the right controlled flooding environment. To help you maximize the success of your rice crop, AMCO has created this guide to building quality levees with our revolutionary levee plow lineup, which includes the hydraulically controlled LF6 and LJ6 and manually controlled MLF6 and MLJ6.
STEP ONE: HITCH AND PREPARE FOR TRANSPORT
Before using your AMCO Levee Plow, double-check that all nuts and bolts are properly tightened and all cotter pins are spread. Make sure the plow has been lubricated.
AMCO Levee Plows are designed to fit category II and III three-point hitches and quick couplers. To hitch the plow to your tractor, simply pin it to the appropriate holes using the spacers provided.
The levee plow comes with standard adjustable parking stands. For transport or field work, the stands should be raised and pinned. For unhitching and storage, the stands should always be lowered to prevent tip-overs.
Caution – After parking the levee plow, always check to make sure it can’t be accidentally overturned.
STEP TWO: ADJUST GANG ANGLES
The gangs may be set at any angle from 18-28 degrees. Under normal operating conditions, the gangs should be set somewhere between these two extremes for the best results. A greater cutting angle will move the soil further and improve penetration. A lesser angle will reduce the number of large clods and the amount of “balling up” the plow may experience in wet conditions. To decrease the gang angle, remove the angle-adjusting pins, located underneath the ends of the main frame. Then, shift the gangs forward and replace the pins at the desired setting. Before cutting, make sure both gangs are pinned off at the same location. To increase the gang angle, move the gangs toward the rear and re-pin.
STEP THREE: ADJUST CUTTING WIDTH
Use the ratchet jack on the side links to adjust the plow’s overall cutting width. For 8-blade plows, use the lower mounting lugs; for 10-blade plows, use the upper mounting lugs.
STEP FOUR: ADJUST GANG TILT
On the MLF6 and MLJ6, the gang tilt is adjusted manually. The LF6 and LJ6 are equipped with on-the-go tilt adjustment, so both hydraulic gangs can be simultaneously tilted from the tractor seat. This feature also allows the operator to reduce the overall number of passes, saving time and fuel. A tilt indicator that displays hydraulic cylinder stroke is located on the right-hand gang of the LF6 and LJ6, letting you know how much the gangs are tilted.
STEP FIVE: CONSTRUCT THE LEVEE
The number of passes required to build a levee depends on the soil condition and the desired depth. Under normal operating conditions, as a general rule, a levee can be constructed in three passes. While there are many methods of constructing a levee, below we have laid out the basic steps of the most common method.
When constructing your levee:
Tip – A “borrow furrow” is formed when nearby soil is used, or “borrowed”, to build the levee. A borrow furrow can help with draining the rice field. If that is not desirable for your operation, use the optional feathering blade kit to reduce the effects of a steep borrow furrow.
Building a high-quality levee helps ensure a successful rice crop. If you have any questions about levee building or about AMCO’s Levee Plow lineup, contact our tough tillage experts today.
Did you know? Both our Manual and Hydraulic Levee Plows are designed with reversible gangs, giving them the ability to both build up and tear down levees.
AMCO’s guide to hitching and operating a ditcher
With spring (and spring rain) on the way, now is the perfect time to brush up on correctly hitching and operating AMCO’s Vertical and Offset Rotary Ditchers. Known for their toughness and reliability, our ditchers efficiently clean roadside ditches and direct water away from crops.
To help you use your AMCO Vertical or Offset Rotary Ditcher to its full potential, we have put together this short guide to hitching and operating these industry best-sellers.
HITCHING THE DITCHER
CAUTION: If you notice that parts of the ditcher need to be lubricated or repaired before operation, disengage the tractor’s PTO and wait for the cutter head and cutting blades to come to a complete stop. Then, slowly lower the ditcher until the skid shoe touches the ground. Before dismounting, shut off the engine, set the parking brake, and remove the key.
Tip: Use the ditcher skid shoe to control the depth of your ditch.
OPERATING THE DITCHER
When hitched and operated correctly, AMCO’s Vertical and Offset Rotary Ditches deliver better ditch-clearing performance and durability. For more instructions on using and taking care of your AMCO Ditcher, review the operating manual or contact an AMCO tough tillage expert.
Visit the Vertical and Offset Rotary Ditchers page on our website to learn more about AMCO’s industry-leading tools.
Did You Know? For the best performance, operate your ditcher at 2.5-5 miles per. Ground speed will vary depending on the soil type, especially in extremely rocky conditions. A good rule of thumb for all conditions is the slower the ground speed, the better the ditcher will perform.
