What do you need a mower conditioner for?
The invention relates to a grass-cutting mower containing a device for spreading grass evenly on the ground after mowing.
The machine in accordance with the real invention contains a frame on which a mowing unit equipped with a cutting device, a grass conditioning system and a tunnel directing the grass to the rear of the machine are mounted. The whole unit is connected by a drawbar to the tractor and is mounted on 2 wheels located at the sides of the machine.
Such a machine has to be able to move relative to the frame together with the cutter bar so that it can follow the configuration of the ground contours. Mower conditioners should also be fitted with lifting aids to avoid ground obstructions and provide transport on roads to prevent the implement from coming into contact with the ground.
Apart from the lifting device, the machine is also equipped with a guard, which is fixed to the cutter bar without moving.
On recognizable machines, the hood, mower bar, conditioning system and grass guide tunnel form a rigid unit designed to move vertically to pass obstacles and for transport.
This rigid unit, in which all elements are joined together, is entirely satisfactory when it comes to the operation of the machine during the mowing. But difficulties arise during conditioning and placing of grass cuttings, when the unit is lifted in order to pass, for example, an obstacle. In this situation, the ejection direction of the grass changes depending on the position of the working tools and the tunnel, so the cut grass does not lie in a uniform layer.
Over, in many machines, taking into account the movement of a rigid unit, and specifically the rear part, when the cutting tools are lifted, it is necessary that the frame is quite high on the ground, and such an arrangement has a negative impact on the stability of the machine.
The task of the invention is to eliminate the above drawbacks by creating a mower-conditioner containing a hood pivotally connected to the grass discharge tunnel, which, in turn, is pivotally connected to the frame.
The intended purpose is solved in a machine of the mower-conditioner type, containing a frame with a grass cutting mechanism mounted on it, equipped with a cutting device, a conditioning system and means for lifting these parts relative to the frame, with all that this assembly is equipped with a guard, and the designated machine additionally contains a grass discharge tunnel located in a specific continuation of the conditioning system, according to the invention the guard is articulated with the tunnel by a transverse axis installed behind the conditioning system, and the designated tunnel, in its.

The mowing bar 3 of the mowing portion may, as is clear, contain discs arranged on a holder side by side, rotating at a high speed in a plane parallel to the ground to cut the grass.
After mowing, the grass is picked up by the conditioning system 4, which may be designed, for example, as a rotating drum equipped with whips which pick up the mowed grass. This drum is partially enclosed by a shroud 13 which starts at the front above the cutter bar 3 where it is connected to the hood 6. The grass is treated in all this to speed up its upcoming drying and then removed to the tunnel 14 for laying on the back of the machine on the ground.
Tunnel 14 extends to the rear of the machine beyond the wheels 9. It contained an upper part 15 and two side plates 16. These side plates were placed in planes pointing in the direction A of the movement and inward from the wheels 9.
Fortschritt E-303 mower conditioner
A variety of equipment was used for each type of forage. For silage and haylage special combines were used, but for hay mowers were mostly used. There were two types of machines, such as tractor-mounted and mounted mowers, and self-propelled mowers.
There were not many self-propelled mowers, but they were made. The farms especially appreciated the Fortschritt E303 mower-conditioners made in the GDR. These German mowers were mainly supplied to the Soviet countries. But after the unification of the GDR with the FRG, the Fortschritt brand gradually disappeared, unable to compete with Western brands. But Fortschritt products, particularly the E303 mower-conditioners, still work today.
Advantages and disadvantages
The Fortschritt E303 mower conditioner was designed for mowing hard-stemmed crops with subsequent flattening of the stalk for faster drying of hay and knocking the cut grass out of the swath. In addition, this self-propelled machine could be used to mow crops in a “stack” for separate harvesting.
The advantages of the Fortschritt E-303 were enough:
- The E303’s powerful power unit allowed the use of reapers and wide-cut mowers;
- Interchangeable working units made it possible to use this self-propelled device for several types of work;
- Structurally, Fortschritt E303 was an uncomplicated device, which ensured its reliability and easy maintainability;
- The design of the E303, in addition to the self-propelled chassis and reaper included several types of windrowers, allowing you to form swaths of mowed crops for specific requirements.
Among the disadvantages of the E303, however, can be noted a strictly defined application of the device, except for mowing grass and crops E303 could not be used.
Mower conditioner E303 was structurally consisted of several basic elements, each of which had its own designation. Thus, the self-propelled chassis was designated as E307. The chassis was of rear-engine design. Originally the power plant IFA 6VD was installed on the E307. Later, the self-propelled chassis was equipped with a D-242 power unit.
Variator transmission for E307. Only one axle was used for propulsion, the front one, and the chassis was controlled by the rear axle.
All controls E307 were located in a sealed cab with a large glass area. To access the cabin, there was only one door. The driver’s comfort is ensured only by the adjustable seat and the ventilation system of the cabin. Mower scheme E-303
KPS-5G self-propelled mower: design and specifications
An important task of the agricultural worker. Mowing seeded grass, for this task using mowers, in this article we will consider one of them. KPS-5G, its device, adjustment and characteristics.
This machine mows grass with simultaneous crushing of stems and laying them on stubble in a swath or bed. Without conditioner, mower can be used as a swath conditioner, but if windrower is installed instead of reaper it can be used for transporting and turning swaths.
KPS-5G mower design
Mower conditioner consists of frame, running system with front driving and rear steering wheels, diesel engine D-240, cutterbar, conditioner unit, drive of operating elements, hydraulic drive of driving wheels and hydraulic system.The reaper is equipped with a cutterbar with two counter-rotating knives and single fingers, a four-sided reel, an auger, a drive mechanism and a break-bar mounted in front of the reel. Reel and headstock can be raised and lowered by hydraulic cylinders.
The conditioner consists of two ribbed rollers, the pressure of which is regulated by springs. Connecting and disconnecting shields behind the rollers to form a swath. Operating elements are driven by diesel engine through the main gearbox, V-belt transmission with a clutch in driven pulley and chain drives.
Rotation to drive wheels is also transferred from diesel engine through the main gearbox, the hydraulic drive system consisting of hydraulic pump and hydraulic motor, three-stage gearbox, central and final drives. Vast hydraulic drive provides infinitely variable speed up to 6.56 km/h in I, up to 13 km/h in II and up to 20 km/h in III gear.
As the machine drives, the piecing bar tilts the crop, the reel pushes it towards the cutterbar and after cutting it feeds the auger which narrows it down to the width of the conditioner. The ribbed conditioner rollers crush and flatten the stalks and then the mass is ejected into the windrower, which forms a swath in the field.
The play between conditioner rollers is set at 8 10 mm. The compression of the spring depends on the thickness of the layer and the properties of grass. The compression force should be 200 300 N per 0,01 m of the rollers length, but in order to flatten the grass stalks, t. Е. Their structural shells are disturbed.
Mower-conditioner cutterbars work tools are adjusted similarly to the corresponding work tools of combine harvesters.Swath-forming shields are set to get the desired width of the mowed swath.
Self-propelled mower KSU-1
Rostselmash” company is one of the five largest world companies producing agricultural machinery. The company consists of 13 plants and production is based in 5 countries: Russia, Kazakhstan, Ukraine, Canada and USA.
Rostselmash products are popular around the world because the company offers an excellent price-quality ratio. According to recent data, Rostselmash has more than 70% of the market for production and sales of agricultural machinery in Russia.
In this article you will learn about the universal self-propelled mower KSU-1. The development and production of the multi-purpose mower started in 2009, together with the production of the new TORUM class 7 harvester.
KSU-1: features and benefits
The KSU-1 self-propelled mower is rightfully considered versatile, as it is perfectly suited for combined harvesting of grain and fodder crops. The mower can not only mow crops, but also lay them in a windrow, crush and flatten forage plants. All this can be done by installing the necessary adapter. This model is ideal for farms that do not just grow a variety of crops, but are also engaged in livestock and forage harvesting.
But what makes KSU-1 better than other mowers?? This question can only be answered after getting a closer look at the equipment of this versatile machine.
The mower is equipped with MMZ D-260 engine, which power reaches 155 liters.С. With a capacity of more than 7 liters. The main advantage of this engine is unpretentiousness in the quality of fuel used. Quite economical under load and with adapters. Fuel consumption does not exceed 3 liters per hectare.
Pneumatic system installed on KSU-1 since 2014, which provides greater autonomy of the mower. Pneumatic system consists of a compressor with automatic pressure support of 4-8 bars and a 100-litre receiver. Quick couplings for connections, which greatly facilitate maintenance of the equipment. In addition, it is worth noting that the pneumatic system provides a reserve of air for 5 minutes of work already after the engine shutdown.
New hydraulic system with a single tank of 50 liters has been installed to improve serviceability and operation. Variable displacement pump guarantees economical power consumption which reduces fuel consumption.
Mower adapters can be attached to the mower without additional parts thanks to the universal hitch system. The main advantage of the universal mounting system is the lateral and longitudinal ground contour following of the adapters offered by the company. No more than 15 minutes to assemble any adapter.
The mower is equipped with a steering rear axle, which has a swing angle of ±8° around the pivot point. The axle has increased stability and balance, which helps achieve high maneuverability. Rear axle is also equipped with hydraulic cylinders and steering trapezium. New design of the last one, enables unfolding of the mower on the spot and backwards and forwards movements without loss of control.
KSU 1 первый укос
Not to forget the wheels on the travel drive. And the design of the axles (steerable and gantry) provides the obligatory transport clearance of 1 meter, which helps the mower to overcome swaths, ditches and bumps unhindered. This is especially important when entering and exiting the field.
Cab of KSU-1
Special attention deserves the cabin of self-propelled multi-purpose mower. Comfort Cab is equipped with adjustable steering column and seat. Refrigeration, audio system, air conditioning and heating for operator comfort. For sun protection a special sunblind has been installed in the cab to prevent direct sunlight. The cab is well soundproofed and has excellent panoramic visibility, making it easy for the operator to respond during work.
There is a control panel and an anatomically designed joystick with quick-reaction buttons next to the operator’s seat for controlling the mowing process. There is also a monitor with a modern Adviser system.
Adviser system is responsible for fuel consumption accounting, collecting and processing information on mower working systems, calculating indicators of work performed, providing information on mower condition, service warnings and much more. With this system, not only can the operator control the mower, but all of the work systems, including the adapters, right from the cab.
In 2017, Rostselmash engineers upgraded the universal self-propelled mower. The new version features an electronic engine management system. A new YAMZ engine has been installed, with an output of up to 180 hp.С., and fuel consumption is up to 7% less.
The front linkage has been strengthened for the Draper Flow 900 adapter. The mechanism increases reliability using additional equipment with reinforced arms with thicker walls and springs. The hydraulic system has also been improved, as the steering pump is connected to a new variable capacity pump. In addition, hose and piping routing has been improved.
Engineers also decided to hide the rear air intake with a vented hood, but the function of its opening remains the same. Fixed panels have been removed between the rear air intake and side hoods. And to improve the ventilation of the motor we added new holes.
New headlamps have been installed on the KSU-1, which have sealed connectors to prevent dust and moisture from entering. And the direction of the light can be changed depending on working conditions.
And of course, the design of the mower has been improved.
Now let’s move on to the technical characteristics of self-propelled mower KSU-1, which are presented in the table.
Let us note at once that there are two versions of KSU-1 with mechanical and without mechanical drive of mowers. Distributors have both the old model of the KSU-1, and with the improvements.
In the table we give technical data on the KSU-1 without improvements.
|Shaft rotation||2100 rpm|
|Power||up to 157 l.С.|
|Tank capacity||340 liters|
|Type of running gear||Wheeled|
|Turning radius||5600 mm|
|Ground clearance||1000 mm|
|Swath opening width||1800 mm|
|Travel speed and working speed||24 km/h and 18 km/h|
|Weight||4769 kg and 4903 kg with mechanical drive|
Attachments are evaluated by cutting height, swath width and number of functional segments. A set of 4 rotors or segments is considered optimal. These enable strips with an average width of 2 to 3 m to be picked up. As the number of functional segments decreases, the width is reduced to 0.5-0.8 m. Modified with optional rotors, these RTGs are capable of cutting a 7- to 9-meter swath at a time. Usually a tractor rotary mower performs these tasks, not the chassis models. The cutting height will vary from 50 to 200 mm. This value is adjusted depending on the conditions of the work. In addition, the work rate is taken into account, which is determined among other things by the power of the tractor. Mowing speeds range from 3 to 15 km/h on average. The most powerful 150hp machines operate at 20 km/h.
Despite the obvious benefits of this multi-tasker, it is not always obvious. First, such equipment requires special technical support and maintenance. Secondly, irrespective of drive train and chassis type, mower conditioners only work well with high horsepower. For example, not every mini-tractor can cope with the simultaneous use of a mower, conditioner and windrower. For this reason, this type of mounted implement is well worth operating on large farms and on rare occasions. Private farms with a complete silage harvesting cycle.
Machine design supposes inclusion of several operating elements. Thus, the self-propelled mower-conditioner provides for a chassis, cab with an operator’s seat, power plant and control unit. By the way, the fuel most often used is diesel. The drive unit is connected to the cutterbar, which performs the most basic operations with the grass. Usually the mounted system is versatile in terms of connecting the working machines. Users can completely change the machine’s functionality with the help of changeable adapters.
In this case, however, the main operating components are the cutting discs, conditioning unit and swathing unit. The tasks of the above-mentioned parts can be complemented by windrowers and grass cutters. Depending on the tasks you need the mower-conditioner to perform, you choose the configuration of the layout of the attachment. The set of operations will, in turn, depend on the requirements of the grass storage and pre-treatment.
