I thought the same thing last weekend after I washed my new B7500 after it's first five hours were logged. I, however, take it a step further. Stupid as it may look to passers by, it goes like this:
Take a leaf blower and blow off all the grass clippings from the tractor and the deck. Especially after you remove the belt covers from the deck. This eliminates spattering wet clippings all over your tractor, and chasing them from side to side of the deck with the hose. Then wash the tractor as you normally would. I use a pressure washer (with care) and rinse with the low pressure setting. Then, take the blower again to blow off the water. This especially works well to rid the deck of standing water on top, and in the curled lip around the outer perimeter of the deck edge. Be careful not to blow water into any orfices or covers. Most of the water that normally drips from the unit and spots your nice wax job will probably be eliminated. This works really well in the joints of the loader arms, and between the cooling fins on the transaxle. Yes, I know your neighbors will look at you like you are nuts, but soon they will be copying you as it works well getting that never-ending water drip from the mirrors on your car or truck that spots the body panels.
Be sure to remove and clean the screen in the radiator and the grille before washing, as wet cottonwood seeds and dandilion fluff stick in the smallest holes while washing.
