Part Number 51192
If your lake bottom is fairly uneven you will want to consider adding flex couplers in between the connection points of your WeedRoller PRO tubes. The lake bottom rollers will simply bolt together through these couplers in a robust, yet flexible, system.
Each linked roller will now be able to flex up to 10 degrees, independently of each other. Meaning, in uneven lake beds, you'll get a greater percentage of the rollers contacting the ground. This will maximize the WeedRoller PRO's ability to clear weeds more quickly and keep your lake bed weed-free longer.
