Traveling at the slowest forward speed with rear deflector fully lowered will give finest possible finish. This deflector adjustment is good for mulching, mixing, and burying weeds, fertilizer, etc. The more you increase forward speed and deflector height, the coarser the finished results will be.
SECTION IV MAINTENANCE AFTER EACH USE 1. Clean all debris from machine especially underside of deck and affixed decals. Replace any missing or illegible decals. 4-1 MAINTENANCE CHECK LIST Perform scheduled maintenance as outlined below. Lower machine to ground, turn off tractor and set parking brake before doing maintenance inspections or work. Some checks may require raising machine off ground and supporting with blocks.

Using a flat blade screwdriver, rotate the fastening pin in its seat 1/2 turn until the head of the pin becomes unlocked in its housing on the cones. (Figure 4-2) 4.
