1Legg Co. "Eliminator" Swather/Header Draper
The Eliminator utilizesa unique fabric for
theside laminate. This fabrichas significantly
greaterstrength (rip resistance) than standard
drapers that merely fold over, or 2 ply, the base
belt material. Thus ELIMINATING premature edge
tear. This design will increase the rip
resistance of the edge of the draper by 50, if
the base fabric is 19oz, and by 30, if the base
fabric is 250z, over the standard folded edge.

Eliminate Cleat Base Tear
The wider base of the ELIMINATOR, in
conjunction with the new chamfered cleat
transition, allows for a smoother transition over
the rollers vs. the old radius or narrow base
cleats. This results in a substantial increase
in draper life.

Eliminate Cleat Base Tear
Patent Pending Eliminator Cleat Base
Short Transition Step starts the cleat into the
pulley. This initial Flex Force Reduction step
starts the distribution of the flex load far from
the cleat base.
The lower profile and unique angle of the chamfer
on the new Eliminator provides for greater
distribution of the flex strain on the belt in
the area where the cleat bonds to the belt.
Eliminating cleat/belt breakage at the cleat
base vs. the old radius or narrow base cleat..
The flat transition distance gets the initial
force off the belt and then starts the load into
the cleat. This thicker rubber area reduces the
destructive forces applied to the base canvas.

Belt Travel Direction
As the belt comes into the pulley there is a
tremendous amount of force being transferred from
the base belt to the cleat as a result of the
tension of the belt vs. the resistance of the
thicker cleat to transform to the pulley. Legg
Co.s Eliminator cleat base is specially
designed to deal with this force. As the Initial
Flex Load point reaches the roller, the load
starts its transfer to the cleat compound. The
small initial step flexes easily which starts the
transfer of force. As the cleat continues around
the pulley, the Secondary Flex Load absorption
point starts picking up the load from the thin
first step. Eventually, as the cleat starts
around the pulley, the special chamfer disperses
the load from the Secondary Flex Load point to
the Primary Flex Load point. Resulting in a
smooth transition around the roller and a much
greater distribution area to Eliminate draper
failure at the cleat base, and the rubber tearing
on the side of the cleat..

Eliminate Crop Slippage and Premature Rod
exposure
New ½ wide beefy cleat results in increased
cleat wear before reaching the glass rod. The
90o cleat angle results in increased bite on the
crop. Moving more crop faster.
½
88 Degree cleat edge. Better bite!
8Competition's Cleat Eliminator Cleat
Greater distance between the glass rod and the
edge of the larger improved Eliminator cleat.
Very small distance on competitions cleat.
The competitions cleat cracks here as a result
of the way the cleat is made.
Force
As the competitions cleat goes around the pulley
the transfer force is directly applied to the
small amount of rubber between the glass rod and
the side of the cleat. This is more than it can
handle and premature cracking in this area may
occur. Once this rubber has cracked the crop
will work its way between the glass rod and the
rubber which forces the rubber up and causes even
more crop to be lodge in there, until the cleat
prematurely fails and the rod is exposed.

Leggs Eliminator cleat has increased rubber
between the cleat edge and the fiberglass rod to
help prevent rod exposure. The new Patent
Pending cleat base design gets the flex force off
that area which will increasing draper life.

Other cleats may prematurely fail here.
Force
The only thing thats absorbing the force of the
cleat being pulled around the pulley here, is the
elongation properties of the rubber. And as the
draper ages, this becomes less and less. Ounce
the rubber in this area of the cleat cracks, crop
will start building up when the crack is pulled
open as the draper goes around the pulley. A
vicious draper killing cycle.
