If the cap was left off the radiator the blockage in there will be the least of the problems.The upper inlet of the block is a highway for mice to get in and set up condos in the block.You can't just flush the block,everything that was carried in through the big openings won't go out the same way.Everything will float up,and get stuck on the openings going up to the head.You will be removing the head to blow everything out.Acorns are notorious for this.You will also most likely find mouse nests knotted up in the water pump impeller.A new or cleaned radiator won't help with a plugged up block.For a tractor I would opt for a repaired and cleaned radiator over a new one.
