14.0.2 Hollow tines.
With hollow tines, the soil can be exchanged. Different sizes are available, see the spare part
manual. The side outlet should face to the rear of the machine.
It is important that the tine angle is set a 90 degrees with hollow coring tines. The tine motion in
the ground is minimum and we create a nice clean hole. If the tine is still moving in the ground,
the hollow tine may break in the end.
If top dressing needs to be applied, use the Verti-Drain first, remove the cores and start spreading
sand.
If a lot of dirt is created during hollow coring, reduce your rpm’s or irrigate first. The dirt may
wear your machine
When the turf is damaged use the solid tines first to establish a healthy root system first or adjust
the working depth.
If the hollow tines block, it means that the ground is (very) compacted and solid need to be used
first to break the ground. Irrigation may help as well, as adjusting the working depth.
@ It is advisable using the dirt protection plates B1, that prevents the cores from entering the machine.
14.1 Turf hold down kit.
A turf hold down kit is available for the 7007, see fig. 18. The part number is 211.700.002. The
kit contains: 12 x C1 self lock nut, 12 x C2 washer, 4 x C3 turf hold down finger and 12 x C4
bolt. The turf hold down fingers fit to the standard assembled front roller scraper. The fingers can
be aligned just before tightening the bolts and nuts.
14.2 Rear roller.
The standard machine is not equipped with a rear roller. A rear roller kit is available by part
number 211.700.004, see fig 19.
The rear roller L is fitted with two bearing blocks M to the rear roller support J with bolts S and
nuts N. Tighten the set screw of the bearing, when the rear roller scraper O is mounted with bolt P
and nut Q to bracket R that is bolted on together with bolt S. The rear roller scraper can be
adjusted by rotating the whole assembly around bolt S.
The rear roller supports J are pivoting around bush I that is tightly fitted with bolt U, washer V
and nut G to the angle plate E. You can choose one of the three holes H as long as both sides are
the same.
The angle plate E is bolted against the main frame of the 7007 Verti-Drain with bolts D and nuts
F.
The chain B that lifts the rear roller when the machine is raised, is fitted between bolt C with nuts
A and bolt T with nut K. The length can be changed by choosing another shackle.
@ Don’t shorten the chain too much, it may damage parts when fully lifted.
@ Grease the bearings with 2 shots every 100 hours.
@ The rear roller can follow certain undulations, but not too much.
@ Do not make any tight turns during work, because the side trust may kill the bearings. Remove
the rear roller first.
