Then work across the first cuts at normal depth. 4 5 3 6 2 7 1 Fig. 10 CULTIVATING Cultivating is destroying the weeds between rows to prevent them from robbing nourishment and moisture from the plants. At the same time, breaking up the upper layer of soil crust will help retain moisture in the soil. Begin by tipping the depth stake forward until it is held by the stake spring. · Cultivate up and down the rows at a speed which will allow tines to uproot weeds and leave the ground in rough condition, promoting no further growth of weeds and grass (See Fig. 11 9 MAINTENANCE RE EA CH FIR US ST E 5H OU RS EV ER Y8 HO UR EV S ER Y2 5H OU EV RS ER OR Y5 0H AN NU OU AN AL RS NU LY OR AL LY AN NU AL LY MAINTENANCE SCHEDULE Check Engine Oil Level Change Engine Oil Oil Pivot Points Inspect Spark Arrester / Muffler Clean Air Cooling System Clean Air Filter Replace Air Filter Clean Area Around Muffler And Controls Replace Spark Plug 1 - Change more often when operating under a heavy load or in high ambient temperatures. 3 - Initial oil change should be performed after first five (5) hours of operations. 2 2 3 1, 2 GENERAL RECOMMENDATIONS The warranty on this tiller does not cover items that have been subjected to operator abuse or negligence.
