Intended use

The subsoiler is an agricultural machine designed for loosening and ae rating soil at a depth of up to 60 cm in order to improve its physical and biological properties. Aeration and irrigation of the lower soil layers obtained thanks to subsoiling ensures an excellent agrotechnical effect, positively affects the development o f plants which have a deeper root system. Subsoiling is performed in a given field once every few years most often (4-5 years). A signal that may indicate the need for subsoiling may be water pool in the spring. After subsoiling, there is no need to perform deep plowing, and one can sow plants by using fruiting tools. The MGX subsoiler used immediately before the fruiting treatments h as a positive effect on the soil structure and improves the conditions for the development of root crops.
CAUTION! The MG X subsoiler is designed exclusively for soil cultivation. Using it for other purposes will be understood as misuse and will result in the loss of warranty.

• careful and unhurried operation of t h e machine,
• careful reading of the operating manual,
• keeping a safe distance from dangerous zones,
• prohibition on staying on the machine and in the machine operating zones when the tractor engine is running,
• performing maintenance works in accordance with safety rules,
• using protective clothes, and in the case of work under the machine also a helmet,
• protecting against access to machine s by unauthorized persons, especially children.

Handling and Usage Information

The subsoiler is usually delivered to t h e customer ready for operation, however, before starting work, the technical condition of the unit should be checked, especially the condition of the operating elements and screw connections. During the inspection, the subsoiler should be secured against tipping over with properly set support legs (they are standard equipment of the subsoiler). Loose screw connections must be tightened During the operation of the machine, the following may be adjusted

• operating depth of tines by changing t he position of the supporting roller in the adjustment handles.
• spacing of operating tines of the subsoiler.

If a subsoiler with supporting roller is purchased, its subassemblies must be assembled during the first preparation of the unit for work. To this end, set t he subsoiler on a flat hardened ground, in a place that allows the roller to maneuver. First of all, mount the tightened holder of t he roller arms in the right place. To transport the roller, use a lifting device with a lifting capacity of at l east 500 kg due to stability during transport. Set the arms in the subsoiler holders and connect the arms with the roller clamp with screws (fig .2) Fig. 2 Connection of the arms with the roller clamp.

Before starting work, the technical condition of the subsoiler should be checked, especially the condition of the operating elements and screw connections.
CAUTION! The correct procedure for assembling the rollers in the arm holders requires the screw to be evenly tightened diagonally so that the entire plane of the arm holders is adjacent to the plane of the roller clamp profile. This is the most reliable way to connect the roller arms to the machine!
The subsoiler also has adjustable spacing of operating tines. It allows to adjust the width of the field sub s oiling. The adjustment is made by loosening the M20 screws in the tine holder, and then moving the tine along the frame profile to t he desired position. After setting all the tines, the loosened screws of the tine holder must be tightened again.
Table 3. Range of operating tines spacing of the MGX subsoiler.

Type of the subsoiler| Minimum working width [mm]| Maximum working width [mm]| Number of tines
---|---|---|---
MGX 2200| 1500| 2200| 3
MGX 3000 (4z)| 1800| 2750| 4
MGX 3000 (5z)| 2200| 2750| 5

Minimum front load when coupled to the rear Coupling the subsoiler with the tractor

The tire pressure of the tractor wheels should be compliant with the manufacturer’s recommendations . The lower links of the three point suspension system should be at the same height, in the spacing corresponding to the spacing of the lower suspension points. When coupling the machine to the tractor, the unit must stand on a hard and even surface. Fig 6 Three point suspension system of the tractor:

• 1,2 lower rods,
• 3 upper link,
• 4 left hanger,
• 5 right hanger with adjustable length,
• lifting arm,
• lifting roller

When attaching the MGX subsoiler to the tractor, perform the following action s

• switch the tractor’s hydraulic system to position regulation,
• remove the lower coupling pins if the tractor’s three point suspension system is not equipped with coupling hooks,
• carefully reverse, hang the machine on the lower links, then se cure,
• connect the upper link of the tractor (in units not equipped with a trolley) during the operation of the unit, the attachment point of the upper link on the machine should be higher than the attachment point of this link on the tractor,
• check lifting, lowering o f the subsoiler and operation of all systems

Each tractor cooperating with the machine must be equipped with a set of weights and maintain controllability in transport, i.e. at least 20% of the tractor’s weight must be loaded on its front axle.

Maintenance and lubrication

Each time after finishing work, the subsoiler should be cleaned of soil, and then parts and assemblies should be inspected. Otherwise, if the rollers get stuck to the soil, resulting in additional load, there may be problems wit h the operation of the machine!

• After the first 4 hours of operation, retighten all screws and then periodically check tightness. Fai lure to do so will cause the play to deepen and result in damage to the machine.
• Lubricate the grease points o n the hinge pins daily during the life of the machine. Bearings of the tubular roller and leveling discs should be lubricated every 25 working hours (does not apply to bearings of maintenance free discs these bearings do not require maintenance and lubrication).
• When replacing worn parts, use thread locker , original screws and nuts.
• Always remember to tighten the screw connections properly.

CAUTIO: Periodic lubrication is a guarantee of machine durability. The durability and efficiency of the machine largely depend s on regular lubrication. Use mineral lubricants for lubrication. Lubrication points must be thoroughly cleaned before pressing or applying grease.
CAUTION! It is forbidden to work on a damaged machine caused by any event that resulted in cracking or deformation of the frame, roller or other machine assembly!

Screw tightening torque
Screws and nuts should be tightened in the machine with the appropriate torque depending on the strength class of the screw and its size and thread pitch. The appropriate tightening torque values are shown in table 4.

Table 4. Tightening torque values for screws and nuts. CAUTION! It is forbidden to work on a damaged machine caused by any event that resulted in cracking or deformation of the frame, roller or other machine assembly!

Service

Due to the simplicity of its design and the materials used, the MGX subsoiler is distinguished by a very low failure rate. To maximize uptime, follow all instructions in this manual for operation, adjustment, lubrication, transportation , and storage of the machine.

Daily service

• Each time after finishing work, the MGX subsoiler should be cleaned of soil, and then parts and assemblies should be inspected. When cleaning, remove soil and plant debris.
• After the first 4 hours of operation, retighten all screws and then periodically check tightness.
• Worn out elements should be replaced with original new ones.
• When replacing worn parts, use thread locker , original screws and nuts.
• Always remember to tighten the screw connections properly.

CAUTION! Periodic lubrication is a guarantee of machine durability.
CAUTION! During maintenance works and replacements, the unit should be secured against rolling. It should be connected to the tractor with the parking brake on and the tractor engine should be turned off. Use the correct spanners and protective gloves during maintenance and repairs, and a helmet if necessary.

Off season service
After the end of the working season, the subsoiler should be thoroughly cleaned, the damage to the paint coating should be repaired, and the worn surfaces of the tines, frame, strings and roller rings, as well as the threads of the adjusting screws should be washed with “Antykor” kerosene and protected against corrosion with “Antykor 1” grease, moreover full lubrication must be carried out. During a break in operation, it is recommended to store the machine under a roof. However, if this is not possible, check the condition of the protection from time to time and, if necessary, replenish the grease washed away by rain.

Servicing the support wheel assembly
Check tire pressure regularly. In the event of a significant loss of air from the tires, check the tightness of the air valve. Then take the wheel to a specialized workshop to locate and repair the damage. Significantly damaged tires (especially profile damage) must be replaced immediately.

Replacement procedures

Replacing the tubular roller bearings If the bearings are damaged, replace them as follows:

• place the machine on an even surface,
• unscrew the four screws securing the ball bearings on each side,
• remove the tubular roller,
• loosen both headless screws in each of the bearings and remove the bearings with a puller,
• put new bearings loosely on the roller,
• roll the roller between the bearing plates and s crew the be a rings to them. Tighten the headless screws using anti loosening adhesive.

Replacement of operating elements

Excessively worn operating elements make it difficult to penetrate the tools and cause an increase in operating resistance. Replacement of wo r king elements should be carried out with the machine lowered to the ground, after switching off the tractor engine. To prevent the replaced elements from touching the ground, place durable pads (e.g. wooden blocks with a thickness of approx. 20 cm under t h e adjacent operating elements or the roller). After lowering the subsoiler, switching off the tractor engine and pulling the handbrake, check the stability of the tractor machine unit. Only standard screws should be used to fasten new elements. In the case of repeated disassembly of the machine components, it is necessary to check and, if necessary, replace the connecting elements, such as screws, washers or nuts, whose excessive wear may lead to uncontrolled loosening of the connected elements, and cons equinely their damage. When working with extremely worn working tools, such work can cause permanent damage to all machine assemblies. Tools should be replaced when their
wear exceeds the values specified in the manual. If the instructions a re not followed, damage may occur for which the manufacturer is NOT RESPONSIBLE !

Replacement of actuators
A malfunctioning actuator, unsealing, etc. should be replaced, dismantled and sent to a specialist workshop. Actuators should be replaced with the machine disassembled. Connect the actuator to the system and, mounted on one side it should cycle several times in order to completely fill the actuator with oil. Otherwise, the lowering section may fall suddenly.
CAUTION! During repairs and maintenance , the machine should be lowered to the ground and supported on supports ensuring full stability, and the tractor engine should be turned off. Us e the correct spanners and protective gloves during maintenance and repairs.

Storage of the subsoiler

The subsoiler should be stored under a roof. In the absence of a roof, it is allowed to store the machine outside. The subsoiler should be stored in a
place that does not pose a threat to people and the environment. In the case of long term storage of the machine outside, maintenance of operating elements should be repeated when the preservative layer is rinsed off. After disconnecting from the tractor, the machines should be supported on a hard and even ground, maintaining permanent balance. All operating assemblies should r est on the ground. The machine should be lowered so as to avoid impacts of operating elements on hard ground. After lowering the machine, disconnect the suspension system and drive the tractor away. Also, elements removed from the machine should be stored firmly supported on the ground, excluding the possibility of uncontrolled movement. It is recommended to store the machine in paved and roofed places, inaccessible to unauthorized persons and animals. Store the machine firmly supported on a hard surface in a way that prevents injury to people or animals

Disassembly and withdrawal

CAUTION! When disassembling the machine, take all precautions using efficient tools and personal protective equipment. Disassembled parts should be disposed of in accordance with the requirements of environmental protection. The unit used in accordance with the rules specified in the operating manual is durable for many years, but worn or damaged elements should be replaced with new ones. In the case of accidental damage (significant cracks and deformations of the frames) that deteriorate the quality of the machine’s operation and pose a threat to its further exploitation, the machine must be withdrawn from use. Disassembly of the machine should be carried out b y persons previously familiar with its construction. These activities should be performed after placing the machine on an even and hard surface. Disassembled metal parts must be scrapped.
