Tilling a yard with Bobcat T66 and Harley rake

Tilling a yard with Bobcat T66 and Harley rake - This customer's yard was vary uneven and the grass was clumpy/ patchy. We used the Harley rake to till up the yard and then we graded it with the bucket. We spread compost / horse manure then used that Harley rake again to mix it in. We covered the area with grass seed and straw
