Never used lawn plug aerator with 32 heat treater tines that penetrate up to 3" in depth thanks to a steel tray with a 330 lb capacity. Tows easily behind lawn tractor or mowers with a tow bracket on pneumatic tires. Control from operator's seat to engage tines or raise them for transit. Local pick up and cash only. No sales tax or shipping to pay for. Save yourself the aggravation of DIY assembly as I have already assembled it and it is ready for use.
