Troy-Bilt 683-Horse Benutzerhandbuch

Section 4: Operation

• Turn the vehicle’s engine off and apply

its parking brake.

• Position the loading vehicle so that the

ramp angle is as flat as possible (the

less incline to the ramp, the better)

Loading the Tiller

1. Use loading ramps that are strong and

wide enough to safely hold the weight of

the tiller and the operator combined—

your tiller weighs between 280 and 325

lbs.
2. Move the Tines/PTO Clutch Lever

(Figure 4-2) into DISENGAGE position.
3. Set the Depth Regulator lever (Figure

4-2) to the Travel position.
4. Move Wheel Speed Lever (Figure 4-2)

into SLOW position and reduce the engine

throttle speed.
5. Shift the Wheels/Tines/PTO Lever

(Figure 4-2) into FORWARD position and

follow the tiller up the ramps (Figure 4-7).

Check the wheels as you move the tiller

forward. Ensure that they move up the

center of each ramp.

6. Prevent tiller from rolling in vehicle.

Leave Wheel Speed Lever in FAST or

SLOW position, chock wheels with blocks

and tie down the tiller.

Unloading the Tiller

IMPORTANT: Never unload the tiller

in FORWARD drive. The tiller could

tip forward and expose you to the

tines (which should be disengaged as

instructed).
1. Use loading ramps that are strong and

wide enough to safely hold the weight of

the tiller and the operator combined—

your tiller weighs between 280 and 325

lbs.

2. Move the Tines/PTO Clutch Lever

(Figure 4-2) to DISENGAGE position.
3. Set the Depth Regulator Lever (Figure

4-2) to the Travel position.
4. Move Wheel Speed Lever (Figure 4-2)

to SLOW position and reduce the engine

throttle speed.
IMPORTANT: Look behind you before you

back down the ramp to ensure that all is

clear. While descending, keep checking

for obstacles behind you.
5. Move and hold the Wheels/Tines/PTO

Lever into REVERSE drive and back down

the ramps (Figure 4-8). Check the wheels

as you move the tiller backward. Ensure

that they move down the center of each

ramp.

Changing Speed Belts

Your tiller has two belt-driven speed

ranges – HIGH RANGE and LOW RANGE

– you pick one or the other by deciding

which set of pulley grooves to move the

forward belt into. By moving the belt

from one speed range into the other, in

combination with the FAST and SLOW

wheel speeds, you obtain a choice of four

different forward wheel speeds and two

different tine speeds.

Changing the belt from LOW range into

HIGH range (or back again) is a matter

of moving the belt from one set of pulley

grooves to a second set of pulley grooves.

This change is done quickly and without

tools (Figures 4-9 through 4-13).

When the tiller is moving in REVERSE, the

wheels are powered by a rubber reverse

disc, not by the belt. Therefore, you have

only two reverse speeds SLOW and FAST,

as set with the Wheel Speed Lever.
Table 4-1 shows the range of wheel and

tine speeds available when using the two

belt speed ranges and the FAST and SLOW

selections on the Wheel Speed Lever.

Changing Belt From LOW Range

to HIGH Range

1. To avoid personal injury, shut off

engine, let all moving parts come to a

complete stop, then disconnect spark

plug wire from spark plug and move it

away from spark plug before making any

adjustments. Wait for the engine and

muffler to cool down.
2. Move Wheels/Tines/PTO Drive Lever

into NEUTRAL.

Figure 4-7: To go up ramps, use
FORWARD drive.

Figure 4-8: To go down ramps, use
REVERSE drive.

To help avoid serious personal injury,

stop the engine, remove the ignition

key, disconnect spark plug wire and

move the wire away from the spark

plug, and let engine and muffler cool

down before changing belt speeds.
