Did a little grading yesterday in my new landscaping project. Used the tired old CC70 & my belly blade. After about 2 hrs I noticed the left rear tire was low, was effecting my grading. I go over to the shop and add a couple PSI, I run them kinda low on pressure. I hear a couple pops, snaps, and finally an area about the size of a SOFTBALL pops out of the sidewall of the tire. Thank Goodness for inner tubes & tire chains. I think the whole sidewall would have split if it wasn't for the chains!
My "Pitstop" was not NASCAR or F-1 quick, about 20 minutes to remove the old tire, swap the chains and the single wheel weight to one of the old 6-12 GY turf tires off the 72 and get back to work.
All I gotta say is the factory GY tires were/are pretty crappy to fail and blow out like that after ONLY 45 yrs.
On clear hard packed dirt the belly blade really works good. I can peal about 1/2 to 1 inch of dirt from all the high spots and drag it into the low spots. Only problems are with grass/weeds, BIG rocks, and roots. I uncover a BIG rock about the size of a softball every now & then!
