Those are reasonable, respectable results for the first year of pulling. If you have enough power to spin out you have enough power to bring the front end off the ground. You need to work on balancing the tractor. This is a matter of weight bracket locations, weight placement, hitch, tire pressure, tire tread, etc. At this point, work on moving weight further back until the front end is just skimming the ground or off the ground 6-12" at the very end of your pulls. See if someone can record your pulls with an emphasis on the back tires. Are they squatting a bit, have a little bit of a wrinkle in the side wall at the end of the pull? You want a shark front edge on your tires with the back of the lugs lower than the front edge. You do not want a lot of tread on the tires. Half the original lug height is plenty on most tracks.
