Is first products the only one who makes aeravators? I called them for pricing on the 40" & 60" units...they refered me to my dealer in which he did not know the price but kept telling me he just sold a 80" unit for $9,300. Second off he asked "how I wanted the unit"....I said "loaded in my truck?" "What do you mean how do I want it?" He then said they have 8 different configurations. I didn't know how to answer him? He said you can buy it one piece at a time or as a package? Does anyone have prices on a 40" & 60" unit? Also how tough are these aeravators? Pretty rugged? can you turn while there in the ground? Im guessing you have no choice but to go slow as a snail otherwise it can't do its job properly? Do you charge more then just core aeration? I feel the extreme need to buy one due to the hard clay soils we have here in the carolinas. Secondly it seems every commercial & HOA property is being done by a aeravator here. I thought maybe im missing out on something.
