11.  REAR CURTAIN (soft sided only) 

 

11.1   Install rear curtain by snapping to the inside back vertical edge of the roof. 
          (see fig. 11.1) 
11.2   (NOTE: adhesive backed velcro should be applied to a clean, dry surface at 
          room temperature.) Apply self adhesive hook velcro, as needed, along the 
          rear legs and rear panel. Adhere rear curtain to newly applied velcro strips. 

 

12.   FINISHING  TOUCHES 

 

12.1   Install wiper motor per instructions included with the wiper kit.

 

12.2   Install 5/16” plastic nut covers on all interior 5/16” locknuts.

 

12.3   

For the 00 Series and 10 Series models 

          (ref.: 4500, 4600, 4700, 4510, 4610, and 4710)

          Install vinyl front fillers by applying self adhesive hook velcro, as needed, 
          along the hood and front legs as shown in figure 12.3. (NOTE: adhesive 
          backed velcro should be applied to a clean, dry surface at room temperature.) 

(NOTE: left, driver’s side shown, repeat for opposite side.) Install front vinyl 
fillers to newly applied velcro strips. 

12.4  

For the 20 Series models 

         (ref.: 4120, 4320, 4520, and 4720)

         Cut the vinyl front fillers as shown in fig. 12.4. Cut along the white 
         lines shown on the photo being sure to cut on the appropriate side 
         of the loop velcro. The photo shows the loop velcro side up. The 

long cut to be made should follow along the edge of the 5/8” wide 
loop velcro so the loop velcro remains fully intact on the small 
piece of vinyl that is labeled “keep for 20 Series”. The shorter cut 
to be made is approximately parallel to the bottom edge as shown 
(finished product is shown in fig. 12.4.1). Apply self adhesive 
hook velcro, as needed, along the hood and front legs. (NOTE: 
adhesive backed velcro should be applied to a clean, dry surface 
at room temperature.) Install the newly cut (saved) portion of the 
front filler to the newly applied hook velcro on the vehicle (not 
shown). 

12.5  Install the rear filler as shown in fig. 12.5 in the same manner 
         as the front fillers. If your tractor is equipped with a backhoe, 
         cut the filler around the hydraulic lines using snips.
