Well, found two bipods left on the place that fit well under the axles, so placed them on 2x12s and used a floor jack to lift each side and remove rim/tire. Did not know one tire was mostly full of water.
Made it quite the task to lift into the pickup. 28 miles from my place to the shop.
New tires are on, and back on the tractor as of yesterday evening. Unfortunately, just as I parked it, saw the left side going down and went flat, so expect the shop did not clean up the rims sufficiently and some burr went through a new tube. Disappointing is a word after all that.
Will see if they are willing to come out and fix this time. Said they are shorthanded at the shop to make trips.
