STEP 2: Attach Handlebar

1.Attach the two legs of the handlebar support (A, Fig. 2-2) loosely to the inner sides of the tiller frame using two 3/8"-16 x 3/4" hex hd. screws (B), two 3/8” flat washers (C) and 3/8"-16 hex locknuts (D).

2.Using using two 5/16"-18 x 1-1/2" hex hd. screws (G), 5/16" split lockwashers

(H) and 5/16"-18 hex nuts (I), loosely attach the the handlebar support (A) using the upper holes.

3.There are three height adjustment holes in the two handlebar support brackets. E & F, Fig. 2-2). Use a setting that will

position the handlebars at approximately

G

waist level when the tines are 3”-4” into

 

the soil. Loosely attach the handlebar

NOTE: If a support bracket will not move, loosen attaching screw (J) and nut.

IMPORTANT: The support brackets must be assembled to the outside of the handlebar assembly.

4. Tighten all handlebar mounting hardware securely.

STEP 3: Move Tiller Off Shipping Platform

To move the tiller without the engine running, put the wheels in their FREEWHEEL position, as described below.

1.Use a sturdy block to raise one wheel off the ground.

2.Remove the hairpin cotter (L, Fig. 2-3) and wheel drive pin (M). Slide the wheel inward on the wheel shaft (N). Reinstall the wheel drive pin and hairpin cotter through the wheel shaft only (not through the wheel hub). Repeat with the other wheel.

3.Using the handlebar as a lever, roll the tiller to a flat area.

IMPORTANT: Before starting the engine, the wheels must be placed in their WHEEL DRIVE position (pins through wheel hubs and wheel shaft). This procedure is described in “Wheel Drive Pins” in
