Operating Instructions AERATION TIPS Should I water before aerating? Best aerating condition is a soft and moist ground. If you are unsure of the ground conditions, as in soil with high clay content, a simple test will determine whether it is necessary to water before aerating. Using a garden hand spade or a large screw driver, you should be able to drive the tool in the ground 2 to 3 inches with little effort. If you are unable to do so, then watering the lawn a day before aerating is necessary.
Operating Instructions THROTTLE CABLE ADJUSTMENT. Model AR25 (Honda Engine Only) 1. Start engine and allow it to reach operating temperature. 2. Adjust the throttle cable at the adjuster bracket by turning the adjuster nut. Tightening will increase engine speed, loosening will reduce engine speed. NOTE: A properly adjusted throttle will slightly increase engine speed as the clutch engages. • If the clutch engages too soon, the engine will stall.
Operating Instructions REAR WHEEL ADJUSTMENT The rear wheel depth/stability control knob (see Figure 6) allows adjustment for better stability and maneuverability by turning knob clockwise. Adjusting for depth by turning knob counter clockwise determines the length of the cores pulled in the following ways: (A)The rear wheels can be adjusted to the level you desire so you can control the penetration of the tines to within a fraction of an inch. The length of the cores pulled can be controlled accordingly.
Maintenance and Service Instructions When operating on hills you should consider the following: (A) Operate the machine up and down the hills rather than across them. (B) Use the rear wheel depth/stability control knob to set the rear wheels for extra stability. This can be a great benefit when you do choose to run the aerator across a hill.

Operating Instructions for Model TA36 What is Aeration? For healthy growth, grass roots need air space in the soil to absorb oxygen, water, and nutrients. Air space in turf soils is reduced when soils are compacted by foot traffic, rainfall, irrigation, during building construction and landscaping. Aeration by mechanically removing small plug (cores) of soil and thatch, greatly increasing the air space in soil.
