The only problem I had, not really a big problem, I made a dolly to store the aerator on. The dolly has 3 inch wheels on 2x4’s on the flat. The dolly is a little too high for the 3pt to connect to. I have to take 2 blocks off the aerator and back the BX over the blocks to raise the tractor off the ground. If I do this I can get the aerator on with no problem, and then slide the dolly out. Getting it off I just reverse the process.
I find putting the tractor in low and pulling the aerator works best. If you go too fast, when you hit a rock it bounces the blocks off the aerator. Besides low gear gives you more seat time! I do a cross pattern, go one way and then the other. I aerator the lawn in the fall and spring. I just leave the cores on the lawn, in a few days they fall apart and into the grass and you can not see them. It pulls nice 3 inch long cores. One thing to check is if you have cable TV make sure you know where it is, because if not, the aerator will find it! Yep I found mine the hard way. I had the cable company come out and bury it deeper when they came to repair the one I hit.
I am pleased with the unit. I purchased the unit local from a Kioti dealer. Ken Sweet was a little more $$ with shipping. I thought I would support the local economy. Well it took 6 weeks to get the unit, dealer told me 1 week, and he wanted to charge me for the pins to attach the unit to the tractor. If I has to do it again, I would purchase it from Ken and get it in a few days like when I got my rototiller from him.
