Tines
The tines will wear with use and should be inspected at the
beginning of each tilling season and after every 30 operating
hours. The tines can be replaced either individually or as a
complete set. Refer to the parts list for tine identification and
part numbers.
a. Tine Inspection:
With use, the tines will become shorter, narrower and pointed.
Badly worn tines will result in a loss of tilling depth, and
reduced effectiveness when chopping up and turning under
organic matter.
B. Removing/Installing a Single Tine:
1. With the engine shut off and the spark plug wire
disconnected, remove the M10×25 bolt, lock washer, flat
washer and M10 nut that attach a single tine to a tine
holder. If needed, use penetrating oil on the nuts.
2. When installing a single tine, be sure to position it so that
its cutting edge (sharp) will enter the soil first as the tiller
moves forward. Hand tighten completely.
C. Removing/Installing a Tine assembly:
1. A tine assembly consists of eight tines mounted on a tine
holder.
2. If removing both tine assemblies, mark them “left” and
“right” before removal. Remove (2) pins and (2) cotter
pins that secure the tine assembly to the tine shaft. If
necessary, use a rubber mallet to tap the tine assembly
outward off the shaft.
3. Before reinstalling the tine assembly, inspect the tine
shaft for rust, rough spots or burrs. Lightly file or sand, as
needed. Apply a thin coat of grease to the shaft.
4. Install each tine assembly so that the cutting (sharp) edge
of the tines will enter the soil first when the tiller moves
forward.
5. Bend cotter pins once inserted to prevent the pins from
coming out.
Checking and Adjusting forward Drive belt
Tension
It is important to maintain correct tension on the forward drive
belt. A loose belt will cause the tines and wheels to slow down
— or stop completely — even though the engine is running
at full speed. A too-tight belt can result in unintentional tine
movement when the lever is in the Neutral (released) position.
–
Check belt tension after the first two hours of break-in
operation and after every 10 operating hours.
–
At the end of each tilling season, check the belt for cracks,
cuts or frayed edges, and replace it as soon as possible.
To Check Belt Tension:
1. Stop engine, wait for all parts to stop moving and
disconnect spark plug wire.
2. With the forward and reverse lever in an open (released)
position, measure and note the overall length of the
cable spring by measuring from the outermost coil to the
outermost coil.
