No rake but the rear blades are a similar design and concern. They either want to roll on their back or tilt forward with the top in to the ground. I use a couple of dolly’s from Harbor Freight and rest the blade on the back. It allows me to easily position the attachment and get the lower arms attached. Once this is done I can lift it off the dolly’s, lower it down and position the blade so the attachment is in its upright position and attach the top link. If no concrete for dolly’s then you could build a small support out of steel or wood that will keep the 3 pt attachment elevated so it is easier to attach/remove.
