Over-The-Row Harvester OR

The Over-the-Row OR combine is equipped with a diesel engine. It works by covering the bushes, shaking them and collecting their fruits. Over-the-Row (OR) offers an excellent solution for harvesting your raspberry or blueberry plantations with the possibility of adjustable options of your choice.

This raspberry harvester is called “Over-The-Row” because the driver and other workers are on top of the machine. The harvester works by shaking the raspberry bushes so that only the ripe fruit falls and is caught in multiple trays and a transport line that transports the fruit directly into boxes after it has been previously cleaned of leaves and other debris with the help of powerful air fans. . This model showed the highest yield with the lowest operating costs for all types of crops.

Seat Driver:  combine is controlled from the driver’s seat with buttons and analog instrumentation
Elevator: Stores and landed safely pallets with raised fruits
Vibrating system:  The system carefully robbery fruit for best quality and has various types of vibrating rods to optimize picking different types of fruit
Work platform: There is enough space to move and store the crates

Frequently Asked Questions

  • Berries, such as raspberries, produce ripe fruit at the optimal time (often 1-2 days) when the fruit is fully ripe. It is in this narrow window of time that the fruit is heaviest and sweetest. Machine picking allows fast picking on a much larger area in a short time than hand picking. The mechanization drastically reduces the need for labor and allows the fast collection of fruits while they are fresh, without them being injured.
  • Machine picking plows the whole bush, not just the visible fruit on the surface of the plant, which is the easiest to reach.
  • Machine picking is a repetitive process in which the operator’s configured machine determines which fruits are ripe at the time of harvest, compared to hundreds of workers who apply their own opinion on how ripe the fruit is.
  • Another advantage of machine picking is the purification ventilation system, which separates the waste and determines which fruits will be stored and which will be discarded. For example, if dried fruit has entered the machine, the cleaning system can be set to remove the fruit before it automatically enters the crates.
  • Machine picking is more hygienic because it eliminates human contact with the fruit, which prevents the transmission of germs and human diseases.
  • Do you plan to use the machine for three or more years?
  • Have you considered the cost of maintaining the machine?
  • Do you have a qualified mechanic in your area?
  • Do you have the financial means to buy the combine?

If you answered “YES” to all these questions, then you may need to buy and own a machine. If your answer was “NO” to some of the questions, then renting a machine would be a better choice.

Raspberries, blueberries, blackberries, coffee, gooseberries, cherries, plums and many other plants with similar sizes and characteristics.

By default, four machine workers is enough. But, depending on the volume of the harvest, you may need one to six people to harvest effectively. For example, a crew of five will consist of one guide, two sorting people, one person to stack crates, and one to fill crates. If there is only one operator, the crop will be harvested in larger containers.

In machine harvesting, there are several possible ways to damage crops. To avoid them, follow these rules:

  • When entering the row, make sure the machine is centered on the row.
  • Once the machine has entered the row (the first catcher has passed through the first stem), it cannot reverse without injuring the plant and or damaging the catchers.
  • Always use the least amount of energy needed to pick the fruit from the plants, experimenting with the machine settings before harvesting.
  • Always release the conveyor belts as slowly as possible to prevent damage.

Yes. Proper field preparation for machine harvesting is very important.

  • Side trimming is important. The wide side branches keep the gripping system open, which contributes to more fruit falling to the ground.
  • The availability of plant beds provides a number of advantages.
    • First, lifting the plant allows the catchers to open less, reducing fruit loss.
    • Raised beds usually have better drainage and protect the plant in wet conditions.
    • Mulching raised beds is good for plants.
    • Installing a pergola is very useful to keep the plants upright. The direction of the plants can allow sunlight to enter the plants better.
  • Longer rows require fewer machine turns to exit and enter the next row
  • You need space at the beginning and end of each row where the machine can maneuver
  • Irrigation systems must be an integral part of the field.
  • The distance between the rows must allow the passage of trucks and unloading machines.
  • Root crops between rows help keep the soil even and firm.
  • The slope of the field must be 3% or less in relation to the harvest. Collection on a side slope can be up to 6%.

Frequently Asked Technical Questions

Check the wire connections and check for damage to the sensors, or check the valve adjustment for the hydraulic automatic control.

Check the hydraulic fluid level, check the electrical connections to the electrical windings and switches. Check the cable connections to the automatic oil cooler switch. Check that the cooling fan is running.

The radiator may need cleaning. Check the antifreeze level. The fuel filter may be clogged or the fuel lines may be pinched.

Check the fluid level in the radiator. Check that the radiator is clean. Check that the fan belt is properly tensioned and check that the water pump is leaking.

The cups may be too loose and may need to be adjusted. Check for damaged chain and / or cups. Check waste cups and clean if necessary.

Check the gears, check the belt adjustment, check for debris and clean if necessary.

Check the battery for proper voltage and check the cable connections. Check the spark plug connections for quick heating or check the setting of the electrical solenoid.

Check fuel lines and waste fuel filter.

The hydraulic fluid pressure has dropped, causing the wheels to lock. Check the hydraulic fluid level. If the level is correct and the brake release pressure varies from 17.2 bar (250 psi) to 20.6 bar (300 psi), you can manually release the brakes by tightening a steel 48mm (5/16 in) x 2.5cm (1 in) bolt with large thread. Check for foreign particles in the hydraulic system by draining and changing the oil.

Check for low hydraulic fluid and check all switch connections and winding wires.

Check the electrical connections to the auto-equalization box and check all switches and their connections. Check for damage to the limiter connections.
