Well done! I was on the tractor myself this weekend cutting grass - the heat was brutal. My spray cart is a Cushman with a 40 gal tank back in the bed. Do you have an issue with the glyphosate separating in the tank after one week? I'm having to use a full tank on each round, 42% is what I use - 1/2 gal per tank. Seems a waste sometimes when I'm done spraying what I need with leftovers. Then dump it. As you know, glyphosate isn't cheap - running $98 for 2 1/2 gallons here at 42%.
