4 SPECIFIC INFORMATION This parts catalog contains service part numbers for replacement parts for your Mud Hog kit. There are six different kits included in this parts catalog. The following information will explain the difference in the kits and which one you have model cotton pickers have had improvements made by John Deere over the 9960 model. To take advantage of these improvements, the Mud Hog kit for a 9965 has some different parts than the Mud Hog kit for a 's use a rocker switch instead of a toggle switch in the cab to turn the Mud Hog on and off. There is a place in the console for the rocker. There is also a place for a fuse and relay assembly. John Deere has included a wire in the wiring harness for Mud Hog hook-up located conveniently near the Equa-Trac II (E-T II) valve. The 9965 also has a built in device that senses neutral and keeps the Mud Hog from running when the transmission is in neutral. This eliminates the need for a wobble switch that is mounted on the transmission cover of a These changes make the electrical installation simpler on a 9965 than a 's also use ORS hose ends and fittings for the flush and drain hook-ups and for the manifold block to the Equa-Trac II valve hook-up. In a 9965, the flush and drain are routed thru holes provided by John Deere in the front wall of the cooler and reservoir compartment. In a 9960, the flush and drain are routed thru the door in the bottom of the reservoir compartment. There is also a difference in some of the parts between System II and System III Mud Hog Kits. System II kits contain wheel motors with 57 cu. in. displacement. System III kits contain wheel motors with 38 or 76 cu. in. displacements. The system III wheel motors are two-speed motors that can be shifted from full to half displacement thru the use of a displacement control valve and an additional toggle switch. Shifting from full to half displacement will give you less pulling power but allow you to run faster than at full displacement. The easiest way to tell if you have a System II or System III kit is by looking at the number of hoses running from the E-T II valve to the wheel motors. System II kits have 4 hoses per side and System III kits have 5 hoses per side. Another difference in kits is in available tread center options. Your kit will adjust from 82" to 90" or from 94" to 118" in 4" increments.
