Use the Transport Speed ONLY when the machine is equipped with a Riding Sulky! NEVER make sharp turns at high speed! The machine has “zero-turn” capability; NEVER use “zero-turn” at high speed.
SECTION 3 - OPERATING INSTRUCTIONS 3.5 MOWER OPERATION (Continued from 3.7 HANDLE HEIGHT ADJUSTMENT Previous Page) 4. Move Engine Speed Control to the FAST (Rabbit) position. Refer to Figure 3.4. 5. While holding both Traction Controls in the neutral position, release Neutral Latch Lever by pulling controls slightly backwards. 6. Simultaneously (and slowly), release both Traction Controls. Machine will begin to move forward. 7. Adjust Speed Control Lever to a comfortable travel speed. 8.
SECTION 3 - OPERATING INSTRUCTIONS 3.7 HANDLE HEIGHT ADJUSTMENT (Continued from previous page) STEP 3: Insert rod (5/16” diameter x 7 3/4” long) through alignment holes in the left and right traction control shift lever arms and the switch bracket. The rod should pass through both the left and right traction control shift lever arms. This step is important as it places the shift lever arms in Neutral and aligns them with the Neutral interlock switches located in the switch bracket. See Figure 3.9.
SECTION 3 - OPERATING INSTRUCTIONS 3.8 ADJUSTING CUTTING HEIGHT (Fixed Decks) SLOT The Mower has three methods of adjusting cutting height listed as follows: 1. Moving position of BLADE on cutter spindle shaft. 2. Moving position of CASTER WHEEL on support. 3. Moving position of MOWER DECK on power unit.
SECTION 3 - OPERATING INSTRUCTIONS 3.11 ADJUSTING FIXED DECK ATTACHMENT SPACERS (4) The Mower Deck has four different positions for attaching it to the power unit. The lowest setting provides a cutting height range from 1 1/2” to 2 1/2”, the middle low cut from 2 1/4” to 3 1/4”, the middle high cut from 3” to 4”, and the highest cut from 3 3/4” to 4 3/4”. Make sure the Spacers on the Caster Wheels are moved UP or DOWN as shown below to correspond with the bolt positions to keep the Mower Deck level.
SECTION 3 - OPERATING INSTRUCTIONS 4. With cell caps removed, connect battery charger to battery terminals. RED to positive (+) terminal and BLACK to negative (-) terminal. 5. Slow charge battery at 1 amp for 10 hours. An alternative fast charge should be no more than 2.5 amps for four hours. 6. If battery will not accept charge or is partially charged after 10 hours of charging at 1 amp, replace with new battery. WARNING Shield the positive terminal with terminal cover located on battery harness.
SECTION 3 - OPERATING INSTRUCTIONS 3.17 NEW BATTERY PREPARATION 1. Remove battery from carton. 2. Place battery in a well ventilated area on a level nonconcrete surface. 3. Remove battery cell caps. Fill cells as required with electrolyte (purchased separately) to proper level. Fill to 3/16” above cell plates. Filling battery with electrolyte will bring the battery to 80% charged state. 4.
