to show the application of the narrow 5/8” wide PSA
(pressure sensitive adhesive) hook velcro. Only three (3)
edges of the rectangle will receive mating velcro. As
shown, do not install the velcro underneath the forward
most edge of the filler so the decal will not be obstructed
and this will allow easier grasping and opening of the
filler for servicing. Note: make sure the surfaces of the
tractor are clean, dry, and at room temperature for best
adhesion of the velcro.

13.3 Per figures 13.3 through 13.3.4, install the larger
underseat filler. Photos continued on the next page. Dry
fit the filler in place to determine where all the flaps fit
best then install the narrow 5/8” wide PSA hook velcro
