FOREWORD Congratulations on the purchase of your VERTI-DRAIN. To ensure the safe and lasting operations of this VERTI-DRAIN you (and anyone using the machine) should read and understand this user’s manual. A complete knowledge of the contents of the manual is necessary in order to ensure the safe use of this machine.
SAFETY INSTRUCTIONS Always use the VERTI-DRAIN with the correct tractor as described in the technical information The user is responsible for a safe Tractor/VERTI-DRAIN combination. The combination must be tested for noise, safety, risk and easy usage. It is also necessary to draw up user instructions.

Fig.1. 2.0 FIRST SETUP, LIFTING MACHINE FROM PALLET The machine stands vertically up on the pallet. To remove the pallet and get the machine horizontal on the ground, handle as follows (see fig.1 ): 1. Open the rear cover 2. Connect a cable to lift point * ensure the cable/crane/lift truck can lift minimum 4000 Kg.(9000 lbs).
Fig.2. 3.0 GENERAL CONTROLS In fig.2. some key details of the machine are shown, as follows: 1. Safety decall RA, before using machine read manual. Decall is located at the toolbox with manuals and combi-tool. 2. Safety decall RB, Keep 4 mtr (14') distance to the machine 3.
4.0 PTO The PTO is a very important item. It drives the machine from the tractor and ensures the safe operations when correctly maintained and installed. The PTO shaft has its own CE certification. Read the PTO shaft manual, which is connected to the shaft itself L standard = 33 mm 1.300"...
4.2 USE OF PTO For the correct use of the PTO, the following items need to be checked: 1. During work the angle of the joints may never exceed 30 degrees 2. The joints have to be in line all the time 3.
Fig.5. Fig.4. 5.0 WORKING DEPTH ADJUSTMENT. The working depth can be adjusted when the machine is lifted from the ground as follows, see fig. 4: Unscrew nuts 1 at each side of the machine one turn. Screw spindle 3 in or out. Every revolution is 4 mm (0.160").
@ The length of the draw rod assembly should be 560.00 mm (22.050"), which can be set by the calibrating shims, see the spare part page Combi Tool Fig.6. 7.0 GROUNDSPEED The groundspeed determines the hole spacing D in the drive direction, see fig.6. The VERTI-DRAIN doesn't need a creeper gear, however if the customer wants a close hole spacing, the groundspeed should be low enough, which depends on the tractor.
Fig.7. 8.0 STARTING PROCEDURES The starting procedure is VERY important. If the start up is not done as described hereunder, serious damage to the machine may occur. Proceed as follows, see fig.7.: 1. Drive to the spot you want to start the operation. 2.
@ NEVER drive backwards, when the lowest tines are less than 120 mm (5") above the ground. If the tines get caught, serious damage will appear on the machine. @ Do not use a hydraulic top link. 9.0 GENERAL USAGE OF VERTI-DRAIN The VERTI-DRAIN can only be used when the circumstances are right.
12.0 PROBLEM ANALYSIS Machine vibrates Crankshaft rotates irregular Machine not at 90 degrees. PTO joint angles different. PTO joints not in line. Tough circumstances Adjust working depth. Use thinner/ shorter tines. If dry, irrigate first. Solid/ hollow tines Wrong tine Change tine, use shorter one.
After every 500 operating hours. gearbox. 14.0 EU-DECLARATION We, Redexim Utrechtseweg 127 3702 AC Zeist Holland, hereby declare fully on our authority that the product: VERTI-DRAIN 7521, WITH MACHINE NUMBER AS INDICATED ON THE MACHINE AND IN THIS MANUAL, to which this declaration relates is according to the stipulation of the 2006/42/EC directive for machines as well as the following standards: NEN-EN-ISO 12100 : 2010 and NEN-EN-ISO 13857 : 2008.
15.0 TECHNICAL INFORMATION Generally speaking, this Verti-Drain is not a complicated machine. A couple of technical items will be explained. If you still have questions, please contact your dealer, who is willing to assist you Fig. 8 15.1 TORQUE SETTINGS. In fig.8., the torque settings of the most important bolts/nuts are given.
Fig.9. 15.2 THE CRANKSHAFT In fig.9. the assembly of the crankshaft is given. Also look at the spare part page for a more clear view and setup. On a 7521 the angle between the handles on the gearbox should be 45 degrees. 5.2.1 REPLACING THE TRANSMISSION OIL SEAL.
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 more damage to other parts, as follows: 1.
16.0 OPTIONS, WHEEL KIT. The part number for a full transport kit for the 7521 is 9500110. This kit will be separately delivered and can be mounted to a standard 3-point linkage machine. Generally speaking, a machine with wheel kit will reduce the minimum horsepower required by 10 HP.
12. Assemble both top links AC between the top link support AH and the draw bar AB with pins AD. Note one side of the top link is bent AI, which should be mounted at AH. 13. Fix the hoses S (long one) and T (short one) to the hydraulic cylinder and 90 degrees connector Y. 14.
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.
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.

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.
16.1.4 REAR ROLLER EXTENSION KIT The kit 211.752.002 can be mounted at the standard rear roller supports and moves the roller further away from the moving parts inside the machine. Since the rear roller is further away from the machine, special attention for shaking of the rear roller is necessary under tough circumstances.
