Farmers often ask “Other than to open a field, why should we windrow potatoes?” The long answer is “Because it's an easy way to boost harvesting speed, utilize the full capacity of the harvesting equipment, decrease equipment costs, and reduce variable costs such as labor and fuel.” The short answer is “Because it makes the most sense.”
Think about it this way. A harvester trailing two windrowers will dig up to four times as many rows as it otherwise could on its own. By extension, it will finish a field up to four times faster. A harvester digging up to four times as many rows will be operating at its full capacity. Years of field tests have proven that running a machine at full capacity improves the percentage of bruise-free product through the machine.
A wise businessman would never spend two dollars for a solution when he can buy something better for only a dollar. The simplicity of a windrower makes it cost considerably less than a full-fledged harvester. Because the harvester loads everything dug from the field into trucks, only one inspection crew is needed. Each windrower theoretically also saves the cost of an additional truck driver and his fuel. Added together, the efficiency boost and cost savings make the 6500 Series Windrower a good business move.
The aggressive slope of the digger bed filters out more soil faster than any other windrower on the market. Operators have found that this allows them to dig at faster ground speeds. To boost digging performance even more, all belted chain rails are less pronounced in the digger bed. That leaves fewer catch points for vines and weeds to build up and disrupt the flow of potatoes.
Digging through 10 to 12 inches of soil is tough. Your implement needs to be tougher. The frame of the 6500 Series Windrower is built to withstand seasons of heavy use in difficult digging conditions.
The 6500 Series Windrower is the first in the industry to position its rear wheels underneath the machine. Having the industry's shortest wheelbase and tightest turning radius make Double L's windrower unbelievably maneuverable. For you this means that your headlands can be utilized more for growing crops than for providing space for turning around the implement.
Wouldn't it be nice if all fields were perfectly flat? If they were, there would be no need for innovative ways to compensate for digging on side hills. The fact is that all fields aren't flat, and windrowers have to dig over uneven terrain. With Digger Pitch and Roll, independent axle cylinders lift or lower either side of the digger bed to line it up with whatever grade you may be digging on.
Operators need to see what's happening all around the machine in an instant. The enormity of these machines can make that difficult. Day or night, cameras in critical spots show the machine's performance and transmit video to the operator of its blind spots.
The ISOBUS port on a tractor provides a 30- and 60-amp electrical circuit to its implement. This is more than adequate to power the windrower's controller and electrical lighting.
Work doesn't always start after sunrise or end at sunset. To be effective in the dark, Double L's field equipment offers the option of LED lighting. It is the brightest, longest lasting field service lighting available.
If the operator doesn't engage the rear cross when he begins digging, it won't take long before the windrower is buried in a mound of potatoes. Using the ISOBUS connection from the tractor, the windrower controller monitors PTO speed and warns the operator if the rear cross hasn't been engaged.
The primary and secondary chains of the 6500 Series Windrower are the longest in the industry. Combined with their aggressive incline, they sift dirt better than any other windrower on the market.
Painted mild steel can only stand up for a short while to the constant abrasion of potatoes and dirt before giving way to corrosion. Stainless steel lining in the digger bed protects both your product as well as your equipment.
A windrower's main responsibility is to augment the capabilities of the harvester. A harvester performs at its optimum when product is balanced evenly through the machine. The dual-boom discharge on the 6500 Series Windrower splits the yield dug by the windrower and distributes it evenly into two furrows in front of the harvester.
A shortcoming of traditional windrowers is that farmers had to order them with either a left- or right-hand discharge. Windrowers with directional discharge are capable of discharging potatoes on both the left-hand and right-hand sides of the machine.
Several functions need to be performed by the operator at the end of each row. Wouldn't it be easier if all of these functions were tied together into an end-of-row macro? We thought so, too.
With some minor calibration, the rear wheels of the windrower can easily be straightened out. Push a button on the controller and the windrower will right itself.
The rear cross on a 6500 Series Windrower is 48 inches (121.92 cm) deep. The yaw adjustment angles the rear cross under the secondary chains so product spreads across the full width of the chain.
Control of the rear cross determines when and where your crop will be discharged. For that reason, tractor operators are given full control of the rear cross from the cab. They can turn it on or off and regulate its speed.
