I went to GIE to test out hydro and ride on aerators. I wanted to demo source1 plugr,lawn solutions,lt rich and turfco. The ride ons at 7,000+ cannot be justified at this point to only be used maybe 6 weeks a year. I had read alot about the lawn solution dual hydro and it is a great machine. Plugr pulls nice plugs but seems abit aggressive on turf. Then i come across the new Turfco hydro wb that has just been introduced. In my opinion this is the smoothest machine out there. It feels just like running a small walk behind mower. A question for those who have the Lawn Solution machine, do you ever have trouble with the chains or any other components under the deck?. The Turfco unit, if you look has very little underneath and the chains are on the outside and very easy to get to without lifting or raising up. If the Turfco unit pulls nice plugs(as someone mentioned the dirt was messed up and it was hard to tell) to me this is the unit i will buy. The one drawback to the Turfco is they will not be offering a sulky to stand on like the LS machine. If i am right the Turfco is about $1000.00 less also. I am sure i will need a ride on at some point and i did demo those also so i will comment. By far the coolest,easiest and most practical for any larger size property is the Lawn Solution hands down. But at $8500.00 you will need to do tons of aerating to justify that cost for a machine that only does 1 thing. The LT Rich has its place by being capable of doing a few other tasks other than aeration. The LT Rich machine is a beast probably not capable of doing smaller areas like i believe the LS machine would. LT Rich builds top quality stuff second to none. One product that did catch my interest was the Z-Rator. Yes, i know there are those on here that have called it junk and not worthy of a look but i saw it used it and think this thing works. Some don't like the gap between the two sets of tines but even if you have to go over the area 2 -3 times it's better than walking on large properties. Another plus is its an attachment that goes on your ZTR so you dont have a dedicated machine. The only thing that might keep me from buying could be the price. I believe it's around $2000.00 and i think it should be somewhere in the $1200.00-$1300.00 range. I am sure the Z-Rator will pull better plugs than all the awful tow behinds that you can never get enough weight on.
