Possible to move deck forward an inch?

I know this may sound weird but I want to move my deck forward about an inch. My soil here is clay type and compacts rather hard. I bought for my rear tires the 1 1/2" spikes you drive on and bolt for a type of aeration. I know it's not true aeration but it could help keeping the soil broken up at times when needed. Only downfall is I can't have these on and mow at the same time.

The left rear tire is clear of the deck about 8" but the right rear of the deck is almost against the rear tire. At the highest setting it's only about an inch from the deck itself. Weird design but it works I guess. The spikes hit the deck at settings 6 and 5 which are the highest. I try to mow in 5 as I don't want to chop the grass to low in say 4.


My tractor is an older Sears Craftsman with a 38" deck dual blade. Again if anyone has any ideas let me know. I can't seem to see anything underneath that would allow me to move it. Just two bolts in the rear to lower it possible. The front is on the bar type hinge to allow it to move up and down.

Argggg..... It would be nice to be able to move and use these spikes most of the summer so when I water most of the water gets down in the holes to help moisten the lawn up.

Any ideas?????
Thanks for your time.
