Yep, that is a two inch receiver in the front of the aerator. ExMark/Toro Company is coming out with a spreader and sprayer attachments that will let you aerate and spray or spread at the same time. I think a real game changer doing two things at once will save on time and money!
Based on the hardness of the ground...you will increase the downward pressure(the machine can go up to 1200 psi) which will give you a deeper plug....but the deeper the plug the slower the machine. I feel you really only need 2 1/2" to 3 1/2" and not 5 inches...which the machine can do.
The handling of the machine is what has really impressed me! It is very quick, easy, and you always feel in control....and that was in a very wet yard. So I am looking forward to getting drier weather here in Northern Illinois...so I get start working through My Customers....since Spring has been here the last 3 weeks!
