This is a Brinley-Hardy spiked aerator, made in the USA, to be pulled behind your mower or a 4 wheeler. It is in excellent condition. Freshly painted. I reinforced the tongue with angle iron as well as installed a fence behind the platform to help hold the weights (such as cinder blocks) in place. All spikes freely rotate, and the 2 wheels are freshly greased. I don't know how old this is but it is very sturdy and the modifications I made make a real difference.
Reason for selling: my lawn situation has changed.
