Flush & Refill

• Remove the radiator cap (10 on previous page).

• Place a container under the radiator drain and loosen

the drain plug 11).

• When the radiator is empty, re-tighten the radiator

drain plug (11).

• When refilling the radiator, see your Kubota Engine

Manual for coolant specifications.

•  Replace the radiator cap (10 on previous page).
•  Fill the reservoir to 3/4 full.
•  With the radiator cap removed, start the engine.
•  Check the amount of fluid in the radiator, adding coolant

as necessary.

• When the coolant level in the radiator remains constant,

replace the cap on the reserve bottle and re-secure the

cover to the top of the engine enclosure.

Cutting Wheel & Teeth

Among the most critical elements of the stump cutter are the
cutting teeth. They are also the most subject to damage and
wear, as in the course of cutting stumps they may encounter
a numerous assortment of abra sives and objects in the
stump’s environment, such as dirt, stones, and occasionally a
large rock or buried scrap. The loss of and wear of teeth can
sig nifi cant ly impair the efficiency of a stump cutter and also
result in overexposure of other teeth, resulting in premature
failure or wear. There fore it is important to make frequent
observation of the con di tion of all of the cutting teeth, and
replace any missing or sig nifi cant ly worn teeth, as soon as
feasible. Read all of the instructions which follow before
changing cutting teeth.

Rayco Teeth

• Safety: Rayco’s cutting tools are always attached with at

least two fasteners. This redundant fastening system is

far safer than those systems employing only one fastener.

Rayco’s cutting tools are also more visible than some of

the other cutting tools that are available. Some of the

cutting wheels available today are “transparent” which

can lead to an operator or bystander becoming confused

as to the actual limits of the cutter tool.

• Proper Balance: Rayco’s cutting wheels and mower

rotors are designed to achieve a dynamic balance that

avoids vibration. Using other cutting tools can set

up vibrations that will harm the machine’s structure &

reduce bearing life.

• Number of Teeth for Depth of Cut: Rayco’s cutter wheels

are designed to provide an economical cutting wheel

assembly solution. The teeth are spaced to provide a

maximum depth of cut for the number of teeth on the

wheel. Some of the wheels available today use a large

quantity of teeth to get the same depth of cut that a

Rayco wheel will achieve with half the teeth. While the

individual tooth cost may be less, the overall costs are

more. Additionally, having too many teeth in the stump

at any one time can lead to aggressive “grabbing” of the

stump, causing the stump cutter to violently hop. This

can cause injury to both man & machine.

• Tooth Projection: Rayco’s stump cutter teeth are

specifically designed to ensure that the carbide tip can
