I see now what it was hitting. In your picture, the bracket it was hitting is to hold a bent wire hanger for storage of the top link. I guess I forgot I took that off my tractor long ago, as soon as I had a hyd top link added and that wire hanger became obsolete. Don't worry about losing that little bracket. And yes, an inch or two of ground clearance was all I ever had too. Once you use the PHD on the 2520 and enjoy the small tractor size and great maneuverability matched to a job that doesn't require a lot of HP anyway, you will forget all about the little bracket. Its a fantastic setup. I always ran mine at just above idle. Oh, one more thing. Weld (or hire it welded) a 4-6 inch pc of tubing, maybe 1.5 or 2 inch inside diameter, crossways (horizontal) on the very top end of the auger bit tube. With this, if your auger ever borrows under a tree root and stalls the tractor, you can put the PTO in free wheel (select the mid PTO instead, using the shift lever), and put a shovel handle or similar thru the welded on tube to turn the auger out of the ground backwards. WAY better than digging it out, or putting a big pipe wrench on the auger tube and backing it out that way. Either way, remember to free-wheel the PTO, and of course ENGINE OFF.
