both sides. Tire pressure in both rear tractor tires must

be identical.

PRIMARY BELT ADJUSTMENT

CLUTCH CABLE INSTALLATION

Tractors with manual clutch mechanism:

Disengage the clutch:

If your cable (item 1) does not have a spring at the end,

attach the cable to the spring (item 3) on the tiller and

attach the cable on the adjustable tension rod (item 2).

Secure in place.

Note: The tension rod (item 2) can be adjusted or

inverted (as shown) to accommodate the length of the

cable.

Note: If you have a cable with a spring at the end, go to

the next step.

If your clutch cable has a spring at the end, you must

remove the original spring from the tiller.

Attach the cable’s spring (item 1) to the extension bar

(item 2). Attach the cable shield on the tension rod (item

3) and secure in place with a hair pin.

Note: The tension rod can be adjusted or rotated to

accommodate the length of the cable.

Install the spring (item 2) that releases the tension on

the belt, the short hook in the idler arm (item 3) and the

long hook on the rod (item 4).

Adjust the cable when the clutch is engaged. The spring

(item 5) should be stretched to approx. 3/4" to 1"

Install the stopper (item 1) with a 5/16 x 3/4" bolt, flat

washer on the slot and flange nut. Adjust the stopper in

order to be sure the belt does not fall off the engine

pulley when the P.T.O. is disengaged. However, the belt

must be loose enough to allow tiller to stop turning

immediately when P.T.O. is disengaged.

OPTION

If your tractor does not have a clutch cable or the cable

is too short, a "clutch mechanism kit" under model

number #700319 is available as an option.

OPERATION

BEFORE TILLING:

-Mow the grass and weeds before tilling, these can wrap

around the tines or tine shaft.

-Remove all objects that can damage the rotary tiller

such as rocks, branches, etc…

-Check the tines before tilling. Repair or replace any

loose, bent or broken tines.

-Do not till when the ground is too wet (if the soil forms a

ball in your hand when squeezed). The wet soil will

stick to the tines and tine shaft.

When breaking ground, it is recommended to till in

two to four stages. The first pass should be tilled at a

shallow depth then progressively deeper with each

pass.

When only a small area is to be tilled, make a pass

through the middle, then circle the pass going

towards the outside.

Whenever possible, till straight ahead, tilling in circles

will leave ridges.

WARNING

TO PREVENT INJURIES AND FOR MORE

TRACTION WITH ACCESSORY:

-Do not drive faster than 3 km/hr (2 m/hr) with the

accessory on the ground.

-Do not drive faster than 10 km/hr (6 m/hr) with

the accessory in raised position.

-Do not operate on a slope greater than 10°.

CAUTION

TO PREVENT INJURIES:

-Remove all objects and keep people away from

the working area.

-Never let children operate the rotary tiller or

tractor.

-Never let children ride on the tractor or rotary

tiller.

-Never operate the rotary tiller without the guards

and shields in place.

-Wearing ear muffs, a dust mask and safety

glasses are recommended.

IMPORTANT

AVOID DAMAGE TO THE ROTARY TILLER

Never back up or make sharp turns with the

rotary tiller in the ground.

-Push the throttle lever to the medium position.

-Disengage the parking brake.

-Put the P.T.O. control in the ON position to engage the

rotary tiller. (See tractor’s owner’s manual for

instructions).

-Lower the tiller and adjust the tilling depth to 1" or

deeper after first pass.

-Engage the transmission in first gear or move forward

slowly if the tractor has a hydro transmission.

-Till the ground at a shallow depth and at slow traveling

speed (3km/h max.)

OPERATING THE ROTARY TILLER

CAUTION

TO PREVENT INJURIES

Tiller may push the tractor forward when tilling in

firm soil and on grass.

Make sure the tractor’s brakes are functional.

Always make sure the engaging system is

functional. If it is not the case, make the required

adjustments.

If the tractor is equipped with a manual clutch,

always stop the tractor’s engine before leaving

the driver’s seat.
