CAUTION: All repair procedures must be done by authorized dealerships. It is not
recommended that untrained individuals perform any repair work. The following
operations are detailed for qualified personnel only.
5.01 - Gearbox
To remove the gearbox from the frame do the following:
1. Never rely on the tractor lift system. Install blocks or stands under the cutter deck to
prevent it from falling.
2. Remove the castle nut safety pin (see #7, fig. 10).
3. Remove the castle nut (see #6, fig. 10) securing the blade carrier rotor to the pinion
shaft. Remove the rotor.
4. Remove the nuts holding the gearbox to the frame and remove the gearbox.
If it is necessary to open the gearbox and replace internal parts, be sure to replace any
oil seals or gaskets to ensure a tight fit when reassembling.
To replace the gearbox, reverse the above operations, making sure the castle nut (see
#6, fig. 10) securing the blade carrier rotor is torqued to 350 lb.ft. and that the safety
pin (see #7, fig. 10) is installed properly.
