  • Page 5: Foreword

    Cultivators • We thank you for choosing and putting your trust on the Multiva S-Tine Harrow. We hope that the product fulfils you requirements and serves you for a long time. We advise you to carefully go through these instructions before commissioning the machine. The inspection and maintenance activities described in these instructions are vitally important for the proper functioning of the machine and the validity of the warranty.

    A type plate similar to the one below is attached to the harrow. Please write all the information from the type plate in this manual. When you are dealing with the supplier of the Multiva machine or a factory representative, please mention the model and serial number of the machine. This is recommended to avoid delays and unnecessary misunderstandings.

  • Page 7: Safety Instructions

    SAFETY INSTRUCTIONS These safety instructions and safety distances must without exception be followed when using the machine. The machine must be configured according to this manual and this manual must be utilised in the operation and maintenance of the machine. Never allow any person to ride the harrow during work or transport! 2.1.

  • Page 8: Hitching And Unhitching

    HIGH PRESSURE HYDRAULIC OIL! Escaping hydraulic fluid under pressure can penetrate the skin causing serious injury! DANGER! Proper function of the locking mechanisms must be checked before any road transport; Locking of the side wings and the ball valve for the side wing hydraulics.

  • Page 9: Using The Harrow

    1. Transport support pin 2. Spring cotter pin The harrow has a transport support which prevents the machine lowering down accidentally in case of a users fault or a sudden leak in the hydraulics. Transport support pin 1 must be set to its hole and locked with pin 2 before any road transport.

  • Page 10: Maintenance

    2.5. Maintenance For maintenance, the harrow must be stopped and it must be blocked to stop it from moving. Maintenance must be carried out on an even and stable surface to prevent the harrow from tipping over or moving. Note the danger of slipping: Do not step on any part of the machine. Maintenance-related and other measures should not be carried out when the harrow or one of its parts is raised and unsupported.

  • Page 11: Commissioning And Basic Adjustments

    COMMISSIONING AND BASIC ADJUSTMENTS 3.1. Measures before commissioning The sections of the harrow requiring lubrication have been lubricated at the factory and oil has been driven to the cylinders during test runs. Still, it is recommended to review the lubrication points before the first period of usage.

  • Page 12: Adjusting Hydraulic Hoses

    3.3. Adjusting hydraulic hoses After hitching the harrow to the tractor, adjust the hydraulic hoses between the hose rack and tractor to a suitable length. The length of the hoses can be adjusted by loosening the hose rack lock (point 1 in the illustration, x 3).

  • Page 13: Operating Principle Of The Front Levelling Board And Depth Adjustment Hydraulics

    Troubleshooting in the event that the side sections cannot be raised, Optima T500 - T700 : Feel whether the pressure reaches the hoses of the side sections' lifting cylinders when the side sections are raised. There is pressure -> Check that the hydraulic return connector is properly attached to the •...

  • Page 14: Harrow Position Adjustment

    3.7. Harrow position adjustment The horizontal position of the frame in relation to the vertical position is adjusted with the top link 1. The adjustment ensures the even working depth of all tines. The position adjustment is tractor-specific and depends on the height of the tractor's tow hitch. When the top link is shortened, the front end of the frame lowers - correspondingly, lengthening the rod raises the front end.
  • Page 15 Optima T500 and T550 Standard models with mechanical cranks for depth adjustment: The centre section limiter pieces adjust the working depth similar to other models. The working depth of side sections is always separately adjusted from the side section crank (point 1). When the crank is turned, the working depth grows.

  • Page 16: Use And Adjustment Of The Harrow

    4.1. Seedbed preparation The Multiva Optima T s-tine harrows are designed to perform seedbed preparation of soil, to which primary tillage has already been carried out, to prepare the soil for seeding. The harrow is used to loosen and crumble the soil to achieve a sufficiently fine result.

  • Page 17: Starting And Setting Into Work Position

    4.3. Starting and setting into work position Raise the harrow to transport height. Ensure that the safety distance of the side sections is clear. Lower the side sections. The lock pieces on the side sections open automatically. Maintain the hydraulics actuated until the cylinders are fully extended.

  • Page 18: Adjusting Working Depth

    4.5. Adjusting working depth Working depth must always be measured from behind the harrow, from tilled soil and the harrow should be adjusted according to each field block and the sown plant. The adjustment must be carried out according to the hardest soil of the block. On softer areas, the working depth may be decreased during tilling by using the depth adjustment hydraulics and the depth indicator.

  • Page 19: Using The Levelling Boards

    4.7. Using the levelling boards The purpose of the levelling boards is to crush clods and even out the level changes of the surface of the field. A correctly adjusted levelling board crushes and mills clods but does not gather a large wall of soil in front.

  • Page 20: Using The Rear Harrow

    The relation between the front and rear levelling boards in Optima T harrows can be quickly changed by using the crank adjustment at the back end of the harrow. The adjustment position can be seen from the scale. 4.8. Using the rear harrow The purpose of the rear harrow is to even out the ridges caused by the s-tine harrow and to sort out the soil material in the tilled layer.

  • Page 21: Using The Cage Roller

    4.9. Using the cage roller The cage roller is intended to crumble clods and even out the ridges left by the s-tines of the harrow. The weighing of the cage roller is adjusted with a crank. Turning the crank clockwise increases the weighing of the roller and turning the crank counter-clockwise decreases it ( point 1).

  • Page 22: Maintenance

    MAINTENANCE In spare part and equipment issues, we recommend contacting the supplier or, if necessary, the manufacturer of the machine. 5.1. Wear parts Mounting of a new s-tine: Set the tine clamp first on to the frame bar. Turn the s-tine through the clamp and place the bolt to the hole.

  • Page 23: Maintenance Programme, Inspections

    MAINTENANCE PROGRAMME, INSPECTIONS The following pages contain detailed instructions. The table can be applied in practice depending on the size of the harrow and amount of field to be cultivated. Service work should be carried out when either the hectares or working days are reached. Table columns: 1 ) After the first 20 ha or after one work day 2 ) After the first 200 ha or after 5 work days...

  • Page 24: Wheel Hub Bearing Clearance

    6.3. Wheel hub bearing clearance The bearing clearance of the wheel hubs must be inspected regularly to avoid the bearings to get damaged. It is very important to tighten them especially during the first operating period, after 50 – 200 ha, when the taper roller bearings have settled in. After that it is enough to check them every 500 ha or once in an operating period.

  • Page 25: Side Section Locking

    6.6. Side section locking The operation of the side section locking must be checked once every operating period before commissioning the machine. There is a spring between the plates of the lock piece that presses the cams behind the plate in the side section (point 1).

  • Page 26: Selector Valve Operation

    6.8. Selector valve operation Optima 500 – 700. When the machine is commissioned, ensure that the selector valve lever is moving without obstructions. The movement is checked by lowering the harrow approximately 50 mm down from the transport position and moving the actuator arm back and forth. The locknut at the end of the thread of the actuator arm must be adjusted so that there is a clearance of a few millimetres in the actuator arm when the harrow is at...

  • Page 27: Maintenance Programme, Lubrication

    MAINTENANCE PROGRAMME, LUBRICATION All lubrication points must be re-lubricated after the machine has been washed. DO NOT use a jet cleaner to directly spray the labels or parts with bearings. Maintain a minimum distance of 30 cm between the nozzle of the cleaner and the sprayed target. Clean the lubrication nipples before lubrication.
