I bought a er074 Terra Force tiller attachment from (Temporarily blocked due to reports of company closure). I dealt with Rick and Travis. Both of them were nice and helpful when sizing my attachment need. Bought it on a Monday or Tuesday and received from Fedex on Friday. The generic video tutorial on their youtube channel was very important because the manual that comes with the attachment is terrible. The diagrams are actually backwards in some instances. Make sure you are prepared to cut the pto shaft. Guarantee it will be too long. I attached a picture of the soil after 2 runs with the er074 Terra Force Tiller
