472H Potato Harvester Owner Operator’s Manual
Turning the screw increases or decreases the gap between
the rubber roller and the steel roller ahead of it. Adjust both
sides evenly.
The Ellis table is hydraulically driven. The speed of the table
rollers can be adjusted by providing more or less oil flow to
the table.
The reverse steel rollers are adjustable back and forth with
the bolt adjustment on either side of the unit. The reverse
steel rollers are also adjustable up and down by using the
rod adjustment on top of the unit. When operating in heavy
trash and grass conditions you may have plugging between
the reverse roll and star roll, if this happens stop the tractor
and PTO. Reverse the direction the rolls turn by reversing
the control lever that operates the tractor valve. Just a few
turns back and forth should clean out the plug. Different
types of reverse roller shafts are available; consult your lo-
cal Lockwood dealer.
There are other small adjustments that can be made to the
table in extreme conditions. Contact your Lockwood dealer
for more information.
The Ellis Table (See Fig. # 45) is mounted at the discharge
end of the side elevator and is intended for use in stony or
loose dirt conditions. The table features adjustable steel
and star rollers. With the rollers spaced apart, small, espe-
cially flat stones and soil will separate from the potatoes.
The greater the gap, the more small stones will fall through.
The steel rollers also feature scrapers that clean the rollers
to keep them running free from dirt.The table is powered by
a hydraulic motor that is connected into one of the tractor
ports. The table becomes more aggressive by slowing the
speed. Refer to your tractor’s operators manual for how to
adjust the flow of oil from the tractor through the external
hydraulic ports.
Adjustment:
Adjust the Ellis Table rollers with the bolts on the rear of the
table. Each roller has an adjustment of .5 inches.
The reverse roll table mounted at the discharge end of the
side elevator is a very effective option for removing dirt, clods,
small stones and trash such as vines and grasses. The table
is powered by a hydraulic motor that is connected into one
of the tractor ports. The table becomes more aggressive by
slowing the speed. Refer to your tractor’s operators manual
for how to adjust the flow of oil from the tractor through the
external hydraulic ports. The inlet end of the table is adjust-
able up and down hydraulically with a toggle switch located
on the control box in the tractor cab. Lowering the table will
make it more aggressive for better cleaning while raising the
table will allow the product to pass over the rollers faster with
less chance to clean but less chance to skin early potatoes.
