Lol....it wasn't too much for the little tractor, it was too much for little me I'd already brought in top soil, tilled and then drug a 14k sqft area in the front previously. I knew how much work that was which is why I took a different route for the back & brought in the skid steer. I spent several days working on the front & knocked out the back in one day.
Have you had a soil test done? If not you should. My soil was very very poor & I spent a couple years amending the soil before I even tried to seed.
Yes, I got a soil sample, which called for a tremendous amount of lime. I had a guy come and put lime out with a truck that fall, then I planted it the following summer. What I should have done was kept working on the soil until I got it right, but all I had was winter grass so I had to do something quick.
