I am picking up mt L4701 in a couple weeks and, this weekend, I am buying a 100 gallon Pak-Tank 3-Point PTO driven sprayer. The sprayer will put 800 lbs (potentially) of water plus the weight of the sprayer itself hanging off the back or the tractor. I will have rimguard in the rear tires and I plan on spraying with the front end loader removed. Any thoughts on the need for and how much weight in front counterweight I may end up needed?
