How do you protect your soils from yield-sapping hardpan?
“Soil compaction is one of the most common problems farmers face today – it severely limits yields and impacts margins,” says Cameron McKenzie, Seeding & Tillage Product Marketing Manager for the farm equipment brand, Challenger. “However, key steps can be taken to deal with it through the use of proper soil management.”
“As the name implies, compaction occurs when soil particles are compacted together, restricting the amount of space for the air and water needed for optimum plant growth. Compaction can occur naturally or be caused by farming practices. Most often, compaction is created by today’s modern heavy equipment traffic. The key to controlling it is to understand your farm’s soils, ascertain the root cause of compaction and learn how to reduce its costly effects.”
“Compaction tends to build up over time and gets worse every time you work your fields – most particularly in wet conditions,” he says. “If you haven’t deep-ripped your fields for example, compaction from a wet spring three years ago can dramatically lower yields further down the line.”
Certain soils compact more easily than others. Soils made up of particles of about the same size compact less than soils with particles of varied sizes. Wet soils compact more easily than dry, while soils high in organic matter have a better structure and are more likely to resist compaction.
Some important things to remember:
- Most compaction is caused by equipment traffic
- Up to 80% of compaction in the field occurs on the first pass of the season
- Surface compaction is caused by high ground pressure created by reduced contact area
- Deep compaction is caused by high axle loads
- Slip compaction is caused by low surface contact areas and smearing of the topsoil
- Pinch-row compaction is caused by dual or triple wheels as ground pressure from the tyres shifts from the centre of the tyre to the outside

While the skies above may look ominous in this picture, the tractors and equipment were in for a day of hard work ahead. Several weeks ago in American Falls, Idaho, AGCO dealer Agri-Service, LLC had its first of a series of events called Fall Tillage days. This is a chance for their customers and prospects get behind the wheel of our tractors and demonstrate them along with our tillage equipment. “In attendance at this particular event were approximately 18 guests representing about 8 local farm operations,” said Adam Hubbard, Marketing Manager at Agri-Service.
Available to demo were a Challenger MT685 pulling a Sunflower 4511 Disc Chisel, a Challenger MT765 pulling a Sunflower 1436 Disc Harrow, and a Challenger MT865 pulling a Sunflower 4630 Disc Ripper. Everyone in attendance was able to demonstrate each of these machines and Agri-Service salesmen as well as AGCO Product Specialists were on-hand to answer questions and point out key features of the equipment and highlight their benefits. All were able to easily demonstrate the ability to till under the crop residue while leaving an impressive finish.
As these machines were parked on a well-traveled road prior to the start of the day, there were some walk-ups inquiring about the impressive display including the static Gleaner Super Series S88 which was prominently showcased as well.
“We had positive feedback from all of the customers that attended. All were able to operate the equipment and were impressed by the tractors as well as the performance of each tillage piece. Some of them had used Sunflower [before] and some hadn’t,” stated Hubbard. When asked if anything in particular stood out to the guests, Hubbard replied, “the SF 4630, the big disc ripper and it performed very well in addition to the incredible ability and performance of the MT865 tractor.”
Agri-Service has three more upcoming Fall Tillage events in October. To learn more, click here.
Sunflower Tillage Experts Offer Preseason Advice for Proper Tillage
No matter what your tillage goal is — residue management, seedbed preparation or preparing for the next crop in a rotation — a properly adjusted and properly used tillage implement will result in fewer trips to the field, better management of the quality and performance of the next crop, and hopefully lower potential erosion.
Tillage experts from Sunflower®, the industry’s full-line provider of tillage and seeding implements, offer some advice for preparing and setting disc harrows before going to the field this fall. These tips apply regardless of the brand of disc harrow you’re working with.
“The goal should be to achieve a consistent, level soil finish across the entire width of the machine, leaving no ridges or furrows,” says Larry Kuster, senior product specialist with Sunflower, a brand of AGCO. “How a machine is set and how it is used really impact reaching this goal, and also determine how effective the machine will be at cutting crop residue, sizing it consistently, and then mixing it into soil to encourage breakdown over the winter.” Kuster offers these tips plus easy-to-follow photos and detailed instructions from Sunflower demonstrating how to set a tillage machine.
Properly pair the tractor and tillage tool. Size does matter, so don’t overpower the tool. A general rule is 8 to 10 HP per foot to pull a tandem disc harrow at 5 to 6 mph. While the design of some tillage tools allows faster ground speeds, going too fast is an easy way to create ridges and furrows. It also can cause tillage tools to bounce, producing an inconsistent tillage depth.
Adjusting the tongue to match drawbar height is important to keep the tillage tool level and moving smoothly through the field, optimizing fuel use and minimizing wear on parts such as the drawbar, level lift assembly and other components that can receive unneeded down pressure if the tool is operated either nose down or tail down. A straight line of draft to the tool is the goal.
Purge air from the hydraulic lines to ensure the wings stay level with the machine’s center section. With the implement’s hydraulics connected to the tractor, simply raise and lower the implement several times to allow the system to cycle fully. Because air is more easily compressed than oil, air in the hydraulic lines can allow the wings to sag.
“If the cylinder sags one-third inch, for example, that could allow the wing to drop approximately 1 inch,” explains Kuster. “That is significant when the tillage depth you’re working toward is only 5 or 6 inches.”
Level the tool from side to side and from front to back to ensure it will work the soil at a consistent, even depth, without gouging or ridging. Keeping the tool level also helps optimize fuel efficiency, reduces wear on the implement, and allows the machine to handle crop residue with less bunching or plugging. Wings and center frames should operate at the same height from side to side. To check these, lower the tool to the ground, stopping the descent when the disc blades are close to the soil but not touching it. Use a tape to measure the distance from the bottom of the frame to the center of the pivot pin on the walking tandem or the top of the wheel spindle if a single or dual wheel is present. The measurements should be the same. Always check the center-section wheels left and right to ensure the integrity of the center lift assembly. Using this same method, set the wings at identical depths by measuring from the bottom of the frame to the top of the wheel spindle or pivot pin of the walking tandem (as shown). If the wheels on the wings are smaller than the main transport wheels, adjust your measurements accordingly.
“The great thing about this method is the operator can use it at the shop or in the field,” says Kuster. “You don’t need a level slab of cement.”
Adjust the fore/aft level so the front and rear blades are of equal distance from the ground. This is a preliminary adjustment. Once in the field, confirm the fore/aft level after traveling several hundred feet with the tool lowered in the working position. Check the soil at the center rear of the tool where the soil is returned by the rear gangs. A tool that is level front to rear will produce a complete and level fill of the valley cut by the front gangs. If soil forms a valley, the rear of the tool needs to be lowered. If a ridge is present, the rear of the tool is too deep, and the tool should be adjusted to lower the front of the machine.
Set the tillage depth to your field conditions and the job at hand. A general rule of thumb for tillage depth of an implement such as a disc harrow is 25 percent of the blade diameter. Thus, a disc harrow with 24-inch blades should be set to till no more than 6 inches deep. Implements such as Sunflower disc harrows have a single-point depth control with a convenient hand crank that adjusts the depth in one-half-inch increments each time the handle is rotated one turn.
“When setting machine depth, be sure the machine carries some weight on the wheels, because the wheels are the base of all the tool adjustments previously made,” explains Kuster. “When the tires don’t have some soil contact, control of the implement is lost.”
Follow these steps to achieve the maximum depth of a disc harrow: Operate the tool with the wheels fully retracted; yes, tires off the ground. Stop after working the soil for a few hundred feet and allowing the disc to achieve maximum depth. Lower the wheels until the tool’s frame begins to lift. At this point, release the valve stopping the ascent of the frame, and stop the tractor but leave the tool in the ground. Adjust the single-point depth-control crank until the striker plate contacts the hydraulic poppet valve. Raise the tool until the audible click of the poppet valve engages, which stops the oil flow. The implement’s maximum depth is now set, and control of the tool is retained.
Gauge wheels are especially important on flexible tillage tools to prevent front-wing corners from gouging. When set correctly, these wheels should move slightly side to side when kicked. A tape measure can be used to ensure the setting for both gauge wheels is consistent. The gauge wheel adjustment is the final step in the field adjustment process.
Operators’ manuals will have full details for specific settings on your machine. For more information about the full line of tillage tools from Sunflower, see your Sunflower equipment dealer or visit www.sunflowermfg.com.

It’s fast approaching harvest time in and around the town of Horsham in Victoria’s west, which provided an idyllic backdrop for a recent photo shoot for Massey Ferguson.
The first star of the show was a new 320hp MF 8680 tractor pulling the new 40’ MF9800 Series single disc air drill. With the camera crew in place, shooting both video and still photography from various vantage points, a great selection of shots were taken showing the awesome power of the MF8680 pulling the new air-seeder through its paces on a fallowed paddock.
Also making an appearance on a beautiful sunny day in the heart of the Wimmera was the new MF9760 self-propelled swather which was fitted with a mower conditioner front and captured making light work of a healthy crop of oats & hay in a nearby paddock.
Shots taken from the day’s shoot will be used in future promotional campaigns. Have you been in the Wimmera lately?
