I have a rear blower as well but one for reverse. I need to adjust the tilt when I am backing up my lane way as it has a slight incline. If I leave the angle the same as I use on flat ground my skid plates dig up the stone. I really do not enjoy the spring time sport of " lets clean up the (rock) wind row on the lawn"I love mine except on the pull snowblower. I will accidentally activate it when I want to just rotate the chute.
I use the standard top link on the blower. No need to change angle of attack on the blower.
