All right, anyone out there who is familiar with late model John Deere dozer operation I could sure use some advice. Next week I'm renting a JD 550 to dig a small pond. It has the standard hydro transimission, single lever steering/direction control, and a decelerator. The 6 way blade is controlled by a single 3 function T bar. I am familiar with older machines that have a hydraulic reverser and a lever for each function and I've never used a machine with a decelerator. I would greatly appreciate if anyone could provide a brief description and any helpful hints on efficient operation with these controls. For instance what does one use the decelerator for? The more time I spend digging versus learning the more pond I get for my money. Thanks in advance.
