Might just be me...running my heavy duty 8' Land Pride rake (built before Kubota bought them) backwards seems to stress the tines and it starts doing some cringe-worthy jumping around.
The curved tine design works perfectly when pulling it forward.
Above, Mr. Vigo and Mr. Old and Tired both mentioned shortening the top link angle to make it work less aggressive.
The top link length is an important adjustment to focus on.
Make it long to aggressively angle the rake tines to dig and pull up rocks and roots.
For finish work, try making it short (and angle the rake about 30 degrees) while maintaining a small amount of soil or gravel in front of the tines to fill low spots as you move forward and see if it works out for you.
You may also find maintaining a slight wind-row as you rake helps when doing final smooth finish work.
One last point is to be aware of the benefit of adjusting the 3PH sidelink to maintain your desired slope from right to left across the horizontal axis, such as when adding crown to a driveway. Adjust the right side lower than the left and you move soil from right to the left, creating slope.
The left to right slope angle can also change as you raise and lower the 3PH depending on how the rake is set up, so watch for this.
And most of all, enjoy the challenge!
It's a hugely rewarding activity once you figure it out, and you are looking back across a smooth patch of ground that you crafted.
