The Shopfitting Shop Rolling Lawn Aerator & Grass Spiker, Manual Rotary Garden Tool Machine, Handheld Push Pull Roll device for home grass yard

I bought this for my dad as he is a very keen gardener. It was very easy to assemble and it is very sturdy. The t-bar handle means that it is very comfortable to use. Great value

Fiddler to put spikes in one by one

Would be useful if the handle height is adjustable. It's fine if you are 6' plus tall but being 5'6" I had problems getting sufficient downward force to get the spikes into the ground to a sufficient depth.
