Damage to the PTO may occur Do make straight passes during work no turns allowed 16 1 OPTIONS TINES Tines are essential for the correct working of the machine Several tines are available for this machine see the spare part pages for a total overview Generally speaking tines can be divided into two categories Solids and Hollows We advise using genuine tines since they are fully adapted to the machine In fig 11 several tine combinations are given The tineholders have 5 x 12 mm 1 2 holes and 2 x 24 mm 1 holes for adapting tines The lock bolt A may be tightened till 40 Nm 30 Ibs ft and B till 70 Nm 50 Ibs ft If the tines still slip out of the adapter grind a flat area to the tine 16 1 1 SOLID TINES Solid tines will break the hard compaction in the ground The tine angle setting see par 6 0 determines the amount of kick action in the ground If the angle is adjusted from 90 degrees up to 75 degrees the kick action increases With a 90 degrees setting we hardly create any tine motion in the ground with 75 degrees we have the maximum tine action in the ground When tines are new they may disrupt the turf specially when the root system is weak Clean the tines first by hand or use the machine for 10 minutes at another rough area If the rootsystem is weak don t try to break the soil much deeper than the root system Adjust the working depth till the penetration is about 7
3. The combination must be tested for noise safety risk and easy usage It is also necessary to draw up user instructions The VERTI DRAIN is suited exclusively to grass fields Every VERTI DRAIN user must be fully informed of the information contained in the user manual Inspect the ground where the VERTI DRAIN is to be applied Remove loose obstacles avoid uneven ground Never step off the tractor if the engine is still running Ensure that other people are standing at least 4 mtr 14 away from the VERTI DRAIN Use appropriate clothing Wear strong shoes with a steel inforced toe cap long trousers tie up long hair Do not have any loose pieces of clothing Never try to force the VERTI DRAIN a situation which is visible in the partial loosening of the front roller from the ground and unstable behavior of the VERTI DRAIN Check the VERTI DRAIN once a week to ensure there are no loose screws or nuts and bolts The VERTI DRAIN may never be used without protection covers and safety stickers NEVER crawl underneath the VERTI DRAIN If you need to work underneath turn the VERTI DRAIN on its front Always switch off the engine and uncouple the power take off before starting any maintenance adjustment or repair Also block the VERTI DRAIN against sinking and block it against forward backward movement or sliding Use only the original VERTI DRAIN spare parts tines in order to ensure the safe operation of the machine Ne

5. 5 mm 3 more than the root system depth This allows the roots to grow deeper Next time penetrate deeper Using this method will safe you from damaging the turf and will establish a healthy rootsystem 20 We advise to use the solid tines with the sharp point facing to the front roller This will create the best tine action in the ground However with a weak turf it is worth using the tines with the sharp edge facing the rear roller The rear roller may not be locked Use always tines with the same length and size Replace a bent tine immediately When this is not done the machine can be unstable Don t use any thicker longer tines as what is offered by us Shorter worn tines can be used in case shallower penetration is required Note that the depth reading on the decall is only correct when using the full maximum length tine If oval holes are created it means that we have a weak top layer and a hard pan underneath Use thinner tines or wait till the wet top layer has dried If topdressing needs to be applied spread it first before using the Verti Drain If the ground is hard to penetrate irrigate first use smaller diameter shorter tines or adjust working depth If not done the machine will be hurt in the end With heavy tines the tine holders may start to float Reduce the PTO speed at that moment immediately because damage may occur when the tines hit the rear roller 16 1 2 HOLLOW TINES With hollow tines the soi

REPLACING THE TRANSMISSION OIL SEAL In fig 9 a top view of the crankshaft is given To replace an oil seal at the transmission handle as follows 1 Loosen nuts II and IV which may be tight because of the loctite Some heat may help Remove big end V after the big end pin VII is removed Remove cover III by unscrewing all the bolts nuts RW N Slide crank VI away from the gearbox using a hammer and hitting it slightly at the center until big end pin VII is free 5 Rotate crank VI and slide big end IX from the big end pin VII 6 Remove handle X after marking the position and removing nut VIII 7 Pull oil seal out with a screw driver 8 Clean area and assemble new oil seal 9 Clean handle X and splined shaft and assemble the handle at the right position 10 Before attaching nut new lock plate first fill the space under the locking plate between the splines and the handle with liquid silicon paste 11 Attach a new locking plate and nut VIII Use loctite for the nut as well 12 Assemble the other parts the same way as they have been removed 13 If the crankshaft seems lumpish see further 15 2 3 15 2 2 REPLACEMENT OF A CRANK WITH BEARING Replacing a crank is necessary when it is cracked or when the big end nuts start to come loose on a regular base Either the crankbearing the crankbearing fitting or the big end pin holes in the crank are damaged Replace the crank bearing as soon as possible to avoid any mor
10. assembly 2 see Fig This can be achieved by the angle A of both clamps 3 and 4 Start with assembling clamp 3 at a distance of 48 mm 2 from the draw rod head end This is critical otherwise the tineholder can t be turned up anymore 21 Next the other clamp 4 can be positioned at a maximum length of 280 mm 11 away from clamp 3 If the length is more measured when the draw rod is in its neutral position damage to the springs and other components may occur Be very careful in fitting the springs on the eye nuts 5 6 because the spring has to be stretched which can be dangerous Itis important to adjust all springs at the same pre tension at a machine The tension can be reduced by reducing the length 280 mm The spring can be taken out as well The tine holder can be turned upwards when the assembly is done correctly Check whether the springs or eye nuts hit something after the installation With the auxiliary springs assembled the capacity may increase but we still have to be aware of overspeeding the machine Like with all other Verti Drains with a rear roller the tines may turn towards the roller and hit the roller for different reasons When we apply too much spring force on the tines especially in combination with the 12 mm V2 we may destroy the hole edge since the spring is pulling hard at the moment the tines are leaving the ground Extra spring force is not advised for such application
11. c depth 4 Are there any hard objects in the ground If so operate the VERTI DRAIN with a very low PTO speed or adjust working depth 5 Is there any danger of flying objects such as golf balls which could distract the attention of the driver If so the VERTI DRAIN can not be operated at that moment 6 Is there any danger of subsidence or land mud slides If so the VERTI DRAIN cannot be operated on the field at that moment 7 Is the ground frozen or very wet Postpone operation till circumstances are better 8 When ground is very compacted use shorter thinner tines to penetrate or adjust working depth 10 0 TRANSPORT OF VERTI DRAIN The user is responsible for the transport of the VERTI DRAIN behind the tractor along the public streets Check on the national legislations Across open ground a maximum speed of 12 km h 8 mph applies In view of the weight of the VERTI DRAIN a higher speed could be dangerous for the driver and bystanders The machine could also suffer damage due to jolt which can occur with higher speeds At least 20 of the tractor weight should rest on the front axle when machine is lifted 11 0 UNCOUPLING OF THE VERTI DRAIN The machine can be disconnected from the tractor as follows 1 Open the rear cover 2 Rotate the crankshaft with the combi tool until both central tineholders right left from the gearbox are at their highest position Turn all other tineholders upwards against the stop Low
