Troy-Bilt 12190-3HP Depth Regulator Lever, Handlebar Height Adjustment, Anti-Reverse Stake

Section 3: Features and Controls

Depth Regulator Lever

This lever (G, Figure 3-5) controls the tilling depth of the tines. Pull the lever straight back and slide it up or down to engage the notched height settings.

The highest notch (lever all the way down) raises the tines approximately 1- 1/2" off the ground. This “travel” setting allows the tiller to be moved without the tines digging into the ground. Also use this setting when starting the engine.

Move the lever upward to increase the tilling depth. The lowest notch allows a tilling depth of approximately 6"-8", depending on soil conditions.

For best results, begin tilling at the deepest depth possible without causing the tiller to bog down. Increase the tilling depth from one pass over the soil to the next.

Handlebar Height Adjustment

The handlebar height is adjustable to three different settings (see Figure 3-6). As a general rule, adjust the handlebars so they are at waist level when the tines are 3"-4" into the soil.

To Adjust the Handlebars:

1.Stop the engine, disconnect the spark plug wire from the spark plug and allow the engine to cool.

2.Remove the screws, lockwashers and nuts, reposition the handlebars, and reinstall the hardware.

Anti-Reverse Stake

This stake is located at the rear of the transmission, under the tine hood (see H, Figure 3-7). Its purpose is to automati- cally help prevent the counter-rotating tines from letting the tiller back up in the direction of the operator if the tiller wheels had been inadvertently left in the FREEWHEEL position. In this situation, the Anti-Reverse Stake will be forced down into the ground, lifting the tines upward out of the soil and helping prevent backward motion of the tiller.

The Anti-Reverse Stake requires no adjust- ment, but should be inspected before each tiller use to verify that it swivels freely. Remove any clogged materials (dirt, roots, rocks, etc.) that prevent the Anti-Reverse Stake from swinging freely.

WARNING

•Place the Depth Regulator Lever in the “travel” position before starting the

engine. This position prevents the tines from touching the ground until you are ready to begin tilling.

Failure to follow this warning could result in personal injury or property damage.
