Smart Top Link

LEVEL UP

Smart Top Link keeps a mounted fertiliser spreader level creating a precise spread pattern. Hydraulic top link is controlled by two sensors, fitted to the front and rear of the spreader, leading to better crop growth and increased yield.

REQUIREMENTS

ISOBUS
Tractor must be ISOBUS compatible to allow communication between the implement and the terminal.

HYDRAULIC FEATURES
System requires load-sensing hydraulic lines and a hydraulic top link installed on the tractor

QUICK GUIDE

INSTALLATION

Smart Top Link’s Control Unit is factory-fitted inside the cabin. The tractor is fitted with additional hydraulic control block and top link to allow automated control of top link. Make sure hydraulic top link is connected to the additional hydraulic block and hoses are connected in the correct orientation.

1. Power on the machine and make sure ISOBUS UT is activated from tractor terminal. Open ISOBUS UT view from the terminal and wait for application to load. After loading, display shows the Home Screen view of the Smart Top Link system.

1. Connect the sensor cables to the 4-pin socket at the rear of the tractor and the other end of it to the sensors.           

2. Turn on the sensor identification mode from your tractors ISOBUS display.   

  • This will make sensors blink in different colours.
  • Mount sensor 1 (Blue) to the rear of the implement
  • Mount sensor 2 (Green/Yellow) to the front of the implement.

3. Attach the sensors to the steel plates            

4. Installing the sensors to the implement

  • Pointing straight down to the ground
  • Make sure sensors are underneath the spreading disc
  • At the minimum height of 30cm from the ground while the spreader at its operating height. Sensors should be approximately at the same height.
  • Both sensors should be approximately in line with each other. Distance between sensors should be minimum of 70cm
  • Installing them to the middle of the implement is preferred.
  • If sensor is too close to the frame of the implement, there might be reflections which affect the sensor reading in a negative way
  • Make sure that the sensors do not collide with ground surface when lowering the implement!

5. Fasten the cables

  • Do not tightly bend the cables.
  • All cables should be securely fastened to the implement's frame.
  • Make sure they are not pinched between metal objects.
  • Cables shouldn’t affect the movements of any implement parts.
  • Ensure that the connectors are properly locked in place.
  • Make sure that the cable is not too loose, being in a risk of interfering with ground surface. 
  • Make sure that the cable is not too tight, being in a risk of braking while the implement is moved.

6. Set implement to working height and make sure it is level with the ground surface.

CALIBRATION

Calibration procedure needs to be executed every time installation of sensors is changed. It is preferred to perform calibration with an empty spreader.

  1. Make sure fertiliser spreader is installed to rear linkage correctly.
  2. Lift fertiliser spreader to operating height (you can check spreader manual for precise height requirements).
  3. Drive on a flat surface 
  4. Make sure the fertiliser spreader is level by measuring front and rear of the spreader manually.

Step 1

Measure distance between the sensors.

Open the settings and add the value to the field.

Step 2

Press calibration button and check that the sensor values seem realistic. You can measure the sensor heights with a measuring tape.

Step 3

Measure the distance of the spreading disc to the ground and enter that into the off set values.

Enter measured value into the offset.

DIAGNOSTICS

  • Ground distance values (raw, filtered, and calibrated values)
  • Average ground distance value.
  • Sensor statuses.
  • Sensor quality values (reliability of the data).
  • Calibration values.
  • Upper limit of the height range (can be adjusted).
  • Upper limit of the height range (can be adjusted).
  • Tilt angle degrees.
  • Offset values.
  • Software version number.
  • NEXT VT (change the ISOBUS UI priority when multiple ISOBUS implements)

SAFETY

Displays and Control Consoles

Make sure that you are familiar operating the tractor and implements and react to any warnings given by tractor.

If Smart Top Link System behaves faulty or gives Diagnostic Trouble Codes, refer to Maintenance manual for further descriptions of causes and resolutions or contact your local AGCO service dealer.

Hydraulic Safety
**Use Only AGCO Approved Top-Link Cylinders

When installing or servicing a hydraulic system or hydraulic components, be aware that hydraulic fluid may be extremely hot and under high pressure. Never attempt to open or work on a hydraulic system with the implement running or under load. The implement or machine must remain stationary during installation or maintenance.

Take precautions to prevent foreign material or contaminants from being introduced into the implement hydraulic system.

Use protection gears and stand clear of the implement when starting the system for the first time after installing or servicing hydraulic components in case a hose has not been properly connected or tightened.

Electrical Safety

Verify that electric harness cables are intact and connected correctly. To avoid entanglement hazards, route cables and harnesses carefully on the implement. Leave enough space for movement and make sure that moving parts cannot touch the cable.

Machine Safety

Make sure that top link has enough range for movement and therefore doesn’t cause implement collision with the tractor or ground surface.

When doing maintenance or other works near the top link or the implement outside the tractor, make sure that the smart top link is switched off.

SOFTWARE UPDATES

Congratulations! There are no required updates.

FAQ

  • Does the Smart Top Link change the application rate?
    - NO, Smart Top Link adjust the angle of the machine

  • Does it automatically adjust the implement height also?
    - NO, but with Smart Top Link you’re able to monitor the height very accurately, making adjustments if needed.

  • Does the crop affect the measurement?
    NO, the sensor measures to solid ground.

  • Does it work on hilly fields?
    - YES, it just keeps the implement parallel to ground (ground that is under the spreader. We use filter on the control system, so small changes on the ground doesn’t matter)

  • Can I use other ISOBUS implement at the same time 
    - YES, ISOBUS screen will have button to change between the screens

  • Can I use my fertilizer spreader that has LS hydraulics together with  Smart Top Link?
    YES,  Smart Top Link has built-in splitter for implements LS aux hose

  • Does the screen view have to be always visible in the terminal?
    - NO,  Smart Top Link can also run in the background.

  • Can this be used on other implements?
    - NO, we have just designed this for use with a fertilizer spreader.

  • Can this be used on any tractor?
    - NO, At the moment we have only tested the Smart Top Link to work on AGCO machines. 

  • Do I plug it straight into my tractor spool valves?
    NO, there is an additional hydraulic block which is installed out of the way on the top of the hydraulic block of your tractor.
