Product Usage Instructions

Kit Installation:

• Step 1:
  Join the two bars (LANRK439) together with the splice bar (LANRK411), using 4 5/16 carriage bolts and flange lock nuts. Make sure not to insert the bolts in the holes that hold the curtain.

• Step 2:
  Install the main brackets (LANRK412) on top of the canvas and its frame. The brackets should extend a minimum of 4 past the front (6-8 preferred) with a pair of 3/8 holes hanging over.

• Step 3:
  Ensure the edges of the brackets are aligned before drilling. Depending on your mower framework:

  • If your mower has round tubes, use the provided 5/16 U-Bolts and washers. Pierce holes through the canvas and slide them through.
  • If your mower has flat sheet metal, clamp the brackets in place and drill through the frame and canvas with an 11/32 bit. Secure with 5/16 hex bolts, washers, and flange nuts.

• Step 4:
  If your mower has a rounded/beveled outer corner, use the longer bracket (LANRK413) to bridge the gap. Clamp in place and drill through the frame and canvas with an 11/32 bit. Secure with 5/16 hex bolts, washers, and flange nuts.

• Step 5:
  Clamp the assembled bar to the mount brackets.

• Step 6:
  Check the clearance between the rear tire and curtain bar by aising the mower to the fully upright position.

• Step 7:
  Drill the 3/8 holes through the curtain bar and fasten.
