Message Board - Machinery: What tines should I use?

11 Feb 2010 by matt hunt

Hi.

Im the chuffed new owner of a vertidrain 7416. As part of the purchase I have been offered a new set of tines. However, Ive no knowledge on this so dont know what to go for.

Heres the background...
Its a school which has one football pitch, a cricket pitch which is used as two rugby pitches over winter. A 'practice' area/playground/general everything lawn, several lawn areas which all get heavy wear.
The soil is sandy but has never been aerated. Water runs across the surface, theres not much grass at all on the lawn/play areas. The pitches have been newly seeded and renovated but are flooding at the moment.
The vertidrain can take upto 3/4x12" (18x300mm) solid or 1x10" (25x250mm) hollow tines.
(just noticed, the liturature states 14" working depth for this unit yet 12" max tine. Hows that work to get 14" depth/)

Any recommendations for what set of tines I should go for? Or can someone point me in the direction of some online reference.
Many thanks

Goes to show, always read the small print.

3/4 inch solid tines set to about 8 inch depth with 80 degree heave as a start. If the ground is too hard and the machine bounces reduce the depth. Once you've vertidrained for a while check the tightness of the tines and their length. We use 1" tines on sand/gravel and they wear an inch a day, 3/4" tines wore too quickly for us. Hollow tine when you want to do soil exchange in spring when you can drag cores around and break them up. Or you'll have a lot to pick up before top dressing.

I have a question:
If you've no knowledge about what sort of tines you want/need why on earth have you got a vertidrain in the first place ?

I think you need to get yourself on a course. You can do some serious damage to your surfaces with a vertidrain unless you know what you're doing with it. I'd expect the course would also discuss what tine for what job.
Give Christine (PitchCare) a ring and I'm sure she'll know of a course somewhere.

Of course there's no bounce, bend your back and put some bloody effort in.

Matt go for the most expensive! you'll find you'll need different tines for different jobs. We have 6 different sets we use on our 7316 ranging from 1" solids to 3/8" pencils . Also make sure you get proper instruction on how to use it because it is a very expensive machine to repair.

Spending money on a vertidrain is a big investment and I would be sure that the company that supplied it would at least spend some time with you as part of the delivery showing you how to set the machine up etc. with some basic maintenance. I recently bought a Weidemann and Chas from the company along with the rep from the company I bought it from spent some considerable time (a whole morning infact) delivering the machine, fitting it to the tractor (including cutting to correct size, the pto shaft so that it would be suitable for our tractor). A thorough explanation was given on general maintenance and tips on how to get the best out of the machine plus a extra set of tines was thrown in at cost and we went for pencil tines as we prefer to use these first to help soften the ground before going onto the thicker tines. He even showed us the best way to fit these to as they fitt slightly differently to charterhoue tines. But in the end I was extreemly impressed as so often machinery is delivered without this sort of back up. Well done Weidemann.
