OK, first off, I need someone to tell me how to start a new topic. I just joined and don't know much about forums. Yesterday I decided to clean my 763 that I bought new about 11 years ago. I'm in the tree business and mostly haul logs out of yards and load them into a dump truck. We also load chips which seem to always fall back onto the operator. Point is, lots of chips dump inside. So I spent 5 hours yesterday cleaning the inside of my 763. I figured out a couple of things while doing this. First, remove two plates on both sides between wheels. this will give access to the drive motors and allow water and debris to escape. Second, there are two drain holes in the belly which will also allow water and stuff to escape. Third, I parked with the back end on the ramps of my trailer. This allows the water to go to the front and flush out all the stuff. I also just used a water hose until I got all of the solid stuff out, then I cranked up the pressure washer to knock off the oil and grease. Total time including pressure wash and some scrub brushing,6.5 hours. I will be doing this at least two times a year for now on and maybe more often. I also have a 2013 s205 which I will be looking at next week. thanks for reading Bob
