The 4-Core manual lawn aerator has side eject coring tines that remove plugs up to 126mm long and 12.7 (or 1/2") in diameter, increasing air and water flow to the roots of the turf and soil reducing compaction in the process. 

If you have a patch of lawn that gets a lot of traffic, doesn't absorb water, is in poor health or recovering then aerating and watering will be highly benficial. 

Our well renowned aerators are made from scratch BY TRIDENT LAWNMOWERS RIGHT HERE IN WA. From cutting the steel tube, drilling the holes, welding and painting, it's all done on site. 

 

Some of the great feature of our aerators include:

* PFVC Grips (forget the foam grips that disintergrate after one summer) 

* Super strong design with no weak points

* professional welding

* Side eject coring tines that dont clog up and eject the plugs effectively 

* Proudly Australian made 

 

* Please note: For international shipping there might be an extra cost involved on top of the automatically calculated shipping fee. Please contact us if you would like to know the total shipping cost before ordering. *

    First manual aerator I’ve used that’s actually pulled cores out. Third times the charm I guess. Built to last and do the job, not to look good and compact soil further like the mass produced rubbish at the big green shed.


    One question - when the day comes where I need to sharpen the tynes, what method should I use ?


    Cheers for a top Australian product

    Thanks Trent. the tines are very hard so wont need sharpening for a while but id use a sanding/ flap wheel in a die grinder or drill.

    Hang on i just read that again. Not to look good?? my girlfriend loves the blue colour! Only kidding, thanks for the review

    Disappointed in the ability to pierce the lawn, no matter how much effort I put into this there was no change. Handle was not suitable to take extra manipulation

    HI Bart, Have you used any other hand corers? how do they compare? We have not had any bad reviews on this product before after selling thousands, happy to hear of your ideas for improvements.

    Also are you using you foot/bodywieght to get it in the ground? normally i throw it in the turf, stand on it with all my weight going through that leg and and if needed wiggle the corer from side to side.

    Really solid piece of equipment, better than any other hand held lawn core aerator I’ve used, delivery was very quick.
