MillCreek makes a small aerator for smaller tractors. I saw one at my Kubota Dealer mounted on the B1500. Its a 3pt mounted 60" wide version. Make shure you get one with the 5 spoon option. More holes per foot with 5 spoon, plus it rolls easyer. I have a 630 millcreek on my Kubota B7500. I know the 630 is over $1500 new. I bought mine used and rebuild it for a total of $450. The smaller ones are just as well built. The are just a little cheaper, have less spoons, smaller frame, weights less, etc. I would recommen looking at one.
