Hints on the right putting into operation of hoes and tined weedereinboeck-wartung-199x134

The "Hoeing and weeding-Season" is just around the corner and we will give some helpful hints for an easier put into operation of your machine at time.

Important: Make familiar with the operating instructions
Before the first use of a new machine always carefully read the operating instructions. Also if you are already familiar with the principal functions of the machine, the manual contains detailed information, which can be very helpful for use and maintenance.

Timely supply of spare parts for used machinery
Used machinery should timely be brought up to date, at the best before the start of the season (e. g. already in winter). Be very thoroughly: That means, change inadequate parts at an early stage or take care you have the adequate spare parts on hand. Wearing parts (as shares or tines) should be available in a sufficient quantity, at best already before the season. Even in organic farming each day a machine cannot be used, you risk to lose the "fight against weeds".

Regular maintenance
Not only before the season, but also during labour care for and maintain the machine. Therefore refer to the specification in the manual. The old saw "Who lubricates well, goes well" is still valid. As a rule it is more effective to lubricate several times with small quantities than press rarely but much lubricant into the bearing. For sealed bearings, too much lubrication can push out the seals. This often causes damages on bearings as a consequence.




Unimportant if front or rear mounted, take care that when hitching onto the tractor, the hoe frame is absolutely even in working position. For rear mounted machines please keep in mind the side links and the lower links are adjusted equally respectively. Only this way a constant working depth over the whole hoeing width can be guaranteed. For the first use exactly adjust the distance between the hoe elements to the row spacing. For obtaining highest accuracy in the field, if possible, move in the same direction than for sowing.
For highest hoe performance of course the unworked surface along the plant rows should be kept as small as possible. Depending on how the machine is guided and how large the plant row already is, this area varies even considerably. Nearest to the plant row can be guided by the camera steering system ROW-GUARD, because the divergences are very low. In combination with e. g. finger hoes the whole surface can be hoed. Almost the same results can be obtained with front mounted hoes. But the success of operation depends highly on the skill and the experience of the driver.
Lateral protecting discs or plates on the hoe element are primarily used to protect from burring the plants in an early stage of development. Adjust the protection plates that way they do not contact the soil, but slightly above. The protection discs should be adjusted that it holds off from the plant the soil of the outer tine.
Choose the hoe depth that all weeds are cut. Too deep hoeing should be avoided; the soil would dry up too much. Further you risk soil run-off in case of a sudden torrential rain. And the increased wear of the shares and the higher fuel requirements speak in favour of keeping the working depth very low. The optional finger hoe with rubber stars pulls fine weed out of the plant row. In order to obtain the best effect and not to damage the cultivated plants, the following adjustments have to be respected: Choose the side distance of the finger hoes to each other that way, that the stars are in a distance of about 1 to 2 finger's breadth to each other, when the fingers are bent upwards like in operation. The spring on the extension of the finger hoe guarantees that the drive star always presses firmly on to the soil. Only when the finger elements lie solidly on the ground, they work best. And the cultivated crop is not rooted or damaged. The spring in normal position should be half-preloaded, then uneven ground (downwards and upwards) can be perfectly compensated. The working speed plays an important role when using finger elements. For small plants, it may not be too high!



Camera steering system ROW-GUARD

The new camera steering system ROW-GUARD holds on line the hoe by a sideshift frame. This frame is mounted without any gap between the rear-mounted hoe and the tractor. For more accuracy the side linkages have to be fixed during operation. The upper link sensor is mounted laterally to the top link fixing points – it is set so that in lifted position the upper link pushes the spring of the sensor and therefore activates the switch. In working position the upper link must not touch the sensor.
The camera is mounted laterally to the hoe frame. Please refer to the table in the manual for how to best adjust the camera at which row distance and for which plant height. Important: The hoe frame is guided by jockey wheels to guarantee always the same distance of the camera to the soil. All further adjustments and the handling can be done via the terminal in the tractor cab. During operation activate the steering, start the constant oil flow, guide between the plant rows, lower the machine and at the moment you drive, the steering starts working. If you find out during operation that the hoe doesn't run exactly between the rows, but is declined towards one side, then correct it by shifting the camera on the hoe frame by exactly the amount into the direction the hoe is misplaced (for example: The hoe runs 2 cm too far to the right, then shift the camera 2 cm towards the right).
The working speed principally depends on the working quality of the hoe. Using the ROW-GUARD speeds up to 15 km/h are no problem.



Tined weeder AEROSTAR

The AEROSTAR is one of the most successful weeders around the world and has been proven thousands of times. The multifunctional use in drilling and root crops makes it an all-rounder in mechanical weeding. Adjustments in terms of aggressiveness highly depend on the cultured crop itself. The general principle is: As aggressive as possible against weeds, but without damaging the culture. When mounting the weeder please consider that the upper link is not too short. During operation the fork should lightly lie on the back element. If you do not have any experience, start with tines in middle position and test on a small surface how this adjustment does work. The quality in work depends highly on the right working speed – the faster the more aggressive.
About 70 % of the effectiveness of weeding is made by covering the weeds in germination phase with earth and only 30 % by weeding.




The AEROSTAR-EXACT was presented at the AGRITECHNICA 2013 in Hannover. Hundreds of machines are already in operation and convince not only by the exact functionality but by the precise adjustment possibilities, too. And it is very simple: For the AEROSTAR-EXACT the tines of 600 mm are always set in light "on hold". This can be done hydraulically from the tractor seat. A notice on one of the outer cylinders helps to find again the desired tine position. The support wheels are adjusted that way the weeding elements run absolutely parallel to the soil during operation. The bolt of the top linkage should be about in the middle of the long hole.
After the principal adjustments you can optimize the adjustment on a small surface. For a considerable adaptation in aggressiveness, position the support wheels upwards (more pressure) or downwards (less pressure). For fine adjustment give more or less pressure on the tines via the hydraulic tine adjustment.




The rotary hoe is easy to handle. The support wheels are mounted that way the lower edge of the main frame is at least 65 cm above the soil; so you can avoid – even with full pressure on the fields – to overstretch the springs. In working position the elements of the machine should be in horizontal position or slightly be inclined rearwards. This allows the same pressure between the first and the second disc row. Via the hydraulically accessed parallelograms the pre-pressure of the discs can be adjusted from the tractor seat. The working speed should be between 12 and 25 km/h. General principle: the faster you drive, the less aggressive the machine works towards the plants.
For the ROTARYSTAR the appropriate time of use is crucial. The best way against muddy and crusted soil is to undertake a passage as soon as possible after rain. That means, when the superficial soil has dried up and the field is not damaged during passage. The crust is fine crumbled at relatively low pressure and the capillary attraction is interrupted. The crumbled structure offers the ideal basis for the following weeding.
