Dedicated to legume-type crops like alfalfa, clover, conditioner rolls are the best answer. Customers cutting legumes need to preserve stems with leaves kept on. With the conditioner rolls, plants are crushed between both rolls of the conditioner. Hard impacts are eliminated. It avoids disconnecting leaves from stalks. Plants travel through the rolls space and are crushed by the pressure applied on the rolls.
Both urethane rolls have pronounced chevrons to increase the pitching point and to decrease dry-down time. Rolls are cold-molded so there is no possible tube distortion. These elements keep the conditioning efficiency consistent, no matter the situation. Conditioner rolls are available for the 630, 635, 830, and 835 Mower-Conditioners.
To improve drying performance, the operator can adjust roll spacing and pressure easily and conveniently. The spacing is adjusted by one wrench, taking 5 minutes maximum.
Cushioned roll stops are used for quiet operation. In coarse grasses, a wider spacing may be more desirable. In legumes, the operator will probably need a narrower spacing. The rolls, being made from urethane, result in better dimensional accuracy during the manufacturing process.
Roll spacing is more uniform over the complete length of the rolls. Bending is virtually eliminated, so that adjustment can be made more accurately.
Roll pressure can be adjusted to match crop conditions. Increase or decrease roll pressure by simply shortening or lengthening tensioning springs (one on each side of the machine).
Because of these two settings, operators will benefit from a highly-durable and high-performance machine.
Due to the rolls working face-to-face, transmission and movement synchronization are keys for success. Power is transmitted downward from the gearbox to the conditoning rolls by a three band V-belt.
Belt tension can be adjusted by a tensioning arm. The long-term conditioner performance and conditioning efficiency depend on the roll synchronization, meaning the rolls bars and holes must be aligned. This alignment is created by the flanges adjustable U-joint system, located on the right. Additionally, the power take-off (PTO) greasers are easy to access. The operator benefits from longer uptime and a high-performing machine.
The HPC system is equipped with preloaded tines which ensure quality crop flow, no matter the cutting condition. The crop is ejected regularly at a higher speed and the windrow forming shield works more accurately.
The impeller conditioner with preloaded tines is one of the reasons for the success of the HPC system. The location and shape of individual tines are located to obtain conditioning efficiency and windrow formation in most crop conditions. The large-diameter conditioner provides high inertia for low-power consumption and higher throughput.
The 600 Series is balanced, resulting in limited to no vibration of the machine, providing more driver comfort. Long-term reliability is also increased. The combination of setting possibilities and the machine’s versatility help to match all challenging condition.
The correct conditioning speed can be chosen by interchanging the two pulleys driving the rotor.
The conditioning hood is now mounted on a parallelogram kinematic. This exclusive market feature provides better conditioning efficiency and decreases dry down time, along with improved crop-flow at higher speeds and produces easy-to-manage windrows.
The conditioning intensity is visible due to a gauge. On 600/800 Series machines, a quick adjustment provides precise clearance between the conditioning hood and the impeller to match crop variety, density, and moisture. A simple crank on the right-hand side of the machine changes the distance between the hood and the impeller, setting the right amount of conditioning for any crop. This adjustment makes work in tall thick grass easier.
High-conditioning intensity is often advised when mowing natural grasses, graminaceous, and short crops. On the contrary, light conditioning is required for daily feeding in combination with a self-loading wagon. The impeller is not designed to condition leguminous, so if the operator chooses to do so, they need to, choose a light conditioning effect. The conditioning intensity is visible due to a gauge as well.
A spiral-bevel gearcase supplies power to the cutting platform. The gears are heat-treated for added strength. The power take-off (PTO) shaft is bolted into the disc through the drum, not directly into the first sprocket. Due to the torque transmitted through the first disc, a dedicated shear hub is installed. It is specially dimensioned to assume the higher torque and correctly protect the cutterbar from shock. The large diameter of the cutterbar’s discs easily support the higher torque.
Three V-band belts ensure an efficient roll and impeller conditioner transmission. (See roll conditioner and impeller conditioner for more information about these systems.)
Standard shields provide windrows positioned in the middle of the cutterbar. The single windrow is easier to manage for machine pick-up not capable to swallow two windrows. The swath width is set using two adjustable deflectors under the conditioning hood. The two forming shields are adjusted by the multifunction tool and the desired windrow width can be adjusted quickly. Windrowing performance of the 600 Series Mower-Conditioner with standard forming shields are exposed in the upper scheme.
NOTE: Approximate distances can vary depending on cutting speed, ground, kind of crop, and yield.
John Deere mower-conditioners provide a wide range of windrows so the operator can easily choose a large swath or high and fluffy windrows. This allows the machine to match varying crop and drying conditions to make better shaped windrows that dry faster and can be picked up easily.
The rear adjustable swathboard allows the operator to adjust the windrow shape. When the swathboard is lowered, the windrow is more compact. When raised, the windrow is aerated. This simple feature is an important machine versatility point. The plate is compatible with all the swath management solutions except the grouper, where a dedicated plate is supplied.
A double windrow of up to 6-m of cut grass can be picked up in a single pass with a 3-m wide SPFH pick-up, reducing operating time and cost. By better self-propelled forage harvester (SPFH) loading, the quality of chop is improved, and the required working speed to optimize the SPFH productivity is lowered. On every second windrow or when the grouper is not needed, the conveyor is hydraulically raised up above the platform.
On the 600 Series impeller machines, widespread options are available to accommodate faster drying. The vanes spread the crop over the full mower-conditioner’s width. By spreading the crop on the ground, the exposed surface is greatly increased, allowing the crop to dry faster and avoiding a tedding operation.
As tedding operation is not required, leaf loss is reduced and crop contamination (stones, dust) is also reduced. Through reducing the drying time, the crop is less exposed to the risk of rain, which may decrease the forage quality. The widespread system is combined with a standard windrow-forming shield. Machine can quickly be adjusted to create single-centralized windrows. Composed of six adjustable vanes under the conditioning hood, it allows changing from windrowing to spreading quickly due to the slots. The crop is spread along the complete cutting width, leaving one free band on the right machine side. This keeps the right tractor wheel from driving on the cut crop.
Powered windrow-forming shields are dedicated to property owners, machinery rings (CUMA), or contractors looking for a cost-effective windrow grouping solution to increase forager productivity. The powered windrow-forming shields are made to group two windrows. The forming shields are linked together and are hydraulically oriented left or right.
From the cab, the driver is moving forming shields using the same selective vontrol valve as the one used for the tongue swing. A diverter valve allows to select mowing shield or tongue. To group two windrows on the first round, the grass flow is diverted toward standing grass. At the beginning of the second round, the operator moves the forming shields to divert the grass flow toward the first windrow.
NOTE: Approximate distances can vary depending on cutting speed ground, kind of crop, yield.
The grouper feature can be used with or without a front mower-conditioner. This implement lets the operator combine two normal windrows. The standard grouper is designed for both the 630 and 635 Mower-Conditioner models and can be used as a single or in combination.
A rubber conveyor belt provides precisely grouped windrows in a variety of crop conditions. The sides of the rubber conveyor are well protected by seals to avoid the material crop penetration inside the belt. Canvas is also used, and has a filament fabric to create strength and resistance to materials such as grass or clay. Along with the filament fabric, the grouper’s belt has friction and skim-coated rubber and is vulcanized under extreme heat and pressure. Junctions are now vulcanized, not sewn, in order to improve belt life.
A solid, heavy-duty, cast tongue supports the transmission. A pivot point to the right of the carrier frame draws the center of gravity to the middle of the mower-conditioner, between the wheels.
Combined with a low center of gravity due to a low carrier frame, the design provides stability and excellent balance for better tracking. Additionally, work and headland maneuvers are improved on slopes.
In cutting, the platform is naturally placed in a perpendicular position to the tractor movement so the machine’s stress is limited. The machine is always working on full cutting width, increasing productivity. Moreover, the tongue shape allows for better road travel to align the machine with the tractor.
The carrier frame is 100 percent welded to support strain and stress, increasing reliability. The wheels are located inside the carrier frame, assuring that the transport width does not depend on the tire size.
The platform frame is dimensioned to keep elements of the machine safe and functional. The frame is able to absorb constraints and keep the cutterbar and the conditioner safe. An integral welded frame supports functional components, keeping them safe by absorbing constraints, thus durability is increased.
The easy access lock system allows the tongue positioning cylinder to be easily locked. The operator only needs to adjust a lever accessible from the rear of the machine to be safe on road. There is no risk that the platform position will change while traveling on the road.
Optional wheel shocks are available for customers looking for safer machine position while parking. They are offered as standard for Germany, Italy, and Spain.
Contrary to a pulled-cutting platform, a pushed-cutting platform has a ground pressure and cutting height that do not vary with the tractor speed, acceleration or deceleration, or when mowing uphill or downhill. The wheel locations are as close as possible to the cutterbar. When driving over a bump, the wheels will follow the ground contour and will lift the cutterbar accordingly. The result is optimum ground contour traction.
The up and down movement of the platform is led by a parallelogram linkage. Two arms connect the platform and carrier frame in the down position and the platform is then pushed by the carrier frame. A single arm used to adjust the cutting height completes the parallelogram.
The cutting angle can be adjusted by a single turnbuckle on the left-hand side of the machine. The changing of the cutting angle affects the cutting height as well. The milled part of the multifunction tool allows the operator to verify the cutting angle or use a previous setting.
An optional hydraulic cylinder lets the operator adjust the cutting height on-the-go (by changing cutting angle) for changing crop or ground conditions. This is useful in a rocky area. The operator can increase the cutting height from the cab to protect the rotating discs and knives. This device requires the use of an additional tractor single acting outlet.
The 600 Series Mower-Conditioners are fitted with a brand suspension design to ensure outstanding floatation performance. The suspension is also active while on roads.
The entire cutting, conditioning, and windrowing unit is laterally suspended with two springs ideally located on both rear sides, resulting in constant ground pressure and quick return to a working position after striking obstacles. This floatation lightens the weight of the machine, providing excellent ground contour following, preserving crop stubble, improving cut quality, and reducing the wear of skid plates.
Each spring can be adjusted dependently on the weight it has to support. Suspension efficiency is also consistent no matter the cutterbar placement. For easier and quicker suspension adjustment, the 600 Series Side-Pull Mower-Conditioners are equipped with cranks and no tools are required. The optimum setting is achieved in a minimum of time.
The platform is hydraulically lifted by two cylinders. It raises and lowers the platform quickly and is conveniently operated from the tractor seat using a single-acting selective control valve (SCV). Once raised, the ground clearance is around 500 mm, facilitating maneuvers and avoiding swath cutting in headlands, pushed cutting platform, ground pressure, cutting height, acceleration or deceleration, mowing uphill or downhill, bumps, and ground contours.
