7.0 DRIVING SPEEDThe effectiveness of the aeration depends upon the condition of the soil, the driving speed,and the speed (rpm) of the PTO.To aerate using the Verti-Quake ® , a driving speed of between 0.5 and 1.5 km/h (0.3 – 0.9mph) is recommended, in combination with a PTO speed of max. 540 rpm.The driving speed and the rpm of the PTO should be adjusted according to the soil conditionand the amount of aeration needed.8.0 START/STOP PROCEDUREThe start procedure is VERY important. If this procedure is not followed exactly as describedbelow, serious damage may occur to the Verti-Quake ® .The start procedure is as follows:1. Visually inspect the Verti-Quake ® and make sure all parts are functioning properly.*!! If they are not, these problems must be resolved before the Verti-Quake ® is to beused !!2. Check the oil level in the gearbox. The oil level should be in the centre of the gaugeglass.3. Connect the Verti-Quake ® to the tractor.4. Drive to the place where the soil is to be treated.5. Lower the machine until the knives are almost touching the ground.6. Switch on the four-wheel drive. Switch on the tractor in the right gear.7. Switch on the PTO at a low speed (rpm).8. Slowly raise the PTO speed to approx. 300 rpm.9. Start the tractor moving and smoothly lower the Verti-Quake ® into the ground.10. Raise the PTO speed to a maximum speed of 540 rpm.11. Raise the driving speed to a maximum of 1.5 km/h (0.9 mph)Fig 12@ Adjust the top rod in such a way that the rear part of the dragging legsare parallel to the ground.This will reduce the pressure of the machine on the ground and willprevent damage to the soil. (fig. 12)@ Always work in straight lines. Curves may damage the soil to betreated.16

Stopping is done as follows:1. Stop the forward movement of the tractor.2. Slowly reduce the PTO speed to approx. 300 rpm.3. Stop the PTO as soon as the knives are out of the soil.4. Gradually raise the Verti-Quake ® from the soil.5. Drive to the next place and start again as described at the beginning of thisSection.*!! NEVER operate the tractor gears when the Verti-Quake ® is operated.The Verti-Quake ® may push the tractor forward at high speed!!@ It is absolutely imperative that the above procedures are followed.If the machine is placed into the soil while the PTO is not running, this maycause serious damage to the machine.@ Always lower the Verti-Quake ® into the soil VERY CAREFULLY.@ Two safety provisions – breaking bolts – have been built into the machine in caseof overloading.− Each knife is provided with a breaking bolt, which will break if the Verti-Quake ® is overloaded.The knife will, however, remain suspended to the main shaft by amounting bolt.− A breaking bolt on the PTO prevents overloading of the Verti-Quake ® andthe tractor.*!! If the breaking bolt is broken, replace it with an original with the correct strengthclass !!9.0 OPERATION OF THE VERTI-QUAKE ®Before the Verti-Quake® is used in any place, the following should be checked first:1. Are there any loose objects lying about in the field? Remove these first.2. Are there any slopes? The maximum slope for the Verti-Quake ® is 20 degrees.Make sure to always move downhill.3. Does the ground contain cables or pipes? If so, determine their depth and set theoperating depth of the machine to 60% of this depth.4. Does the ground contain hard objects? Adjust the operating depth accordingly.5. Is there any danger of flying objects, such as golf balls, which may distract the attentionof the driver? If so, do NOT use the Verti-Quake ® .6. Is there any danger of sagging or sliding? If so, postpone working with the Verti-Quake ® .7. If the soil is frozen or very wet, the treatment should be postponed until thecircumstances are more favourable.17

10.0 TRANSPORT OF THE VERTI-QUAKE ®The user is responsible for the transport of the Verti-Quake ® behind the tractor whentravelling public roads. Check the national traffic regulations.On open fields, a maximum speed of 12 km/h (7.5 mph) should be observed, because of theweight of the Verti-Quake®.A higher speed may endanger the driver and/or other people and may even damage themachine.* When the machine is in raised position, at least 20% of the weight of the tractorshould be supported by the front axle.11.0 DISCONNECTING THE VERTI-QUAKE ®Fig. 13The machine is disconnected from the tractor as follows:1.
