Seven Tests We Run on Each and Every Design of Green Grippers

The Craftsman front-propelled mower featuring Green Grippers is designed to overcome a variety of obstacles, including navigating a combination of sand, small rocks, roots, and St. Augustine grass. Seven rigorous real-world assessments are conducted to evaluate the performance and durability of the Green Grippers lawn mower wheel attachments.
    1. Hill Climb Test: We have heavy to moderate inclines on our property with the (sand, small rocks, roots, and St. Augustine grass) mentioned terrain mix. Engage the mower’s self-propelled function to climb the hill and navigate the ditches. Observe if the Green Grippers maintain traction or slip excessively. 

    2. Sharp Turn Test: In an open area with the full terrain mix, (sand, small rocks, roots, and St. Augustine grass). We mowed a tight circle at a moderate to fast speed. See if the Green Grippers hold or cause the mower to lose control. Repeat at various speeds to see if any issues arise. Watch Video

    3. Root Obstacle Course: We mow a designated path with a high concentration of tree roots. Feel for any vibrations or hear scraping noises that might indicate the Green Grippers are making excessive contact with the roots. Inspect the wheel attachments for signs of damage after each test. See Pictures and Video

    4. Durability Test: We mow a designated area representing your typical mowing path for several sessions (consider 8-14 mows). We look for visible signs of wear and tear on the Green Gripper wheel attachments. Click Here for pictures. Looking for tread wear or wheel cover cracks. This helps us assess long-term durability.

    5. Hot Sun and Cold Rain: We also keep a test wheel cover in the hot Florida sun through the Summer and expose them to the brisk and wet winters in N. Florida. 

    6. Wet Grass Test: Early in the morning in Florida or after a light rain, mow a section with wet St. Augustine grass, sand, dirt, rocks, and roots. Observe if the Green Grippers lose traction or clog with mud. See if mowing efficiency is significantly impacted. Click for Test Pictures and Videos

    7. Loose Material Test: We have loose dirt and, a sandy area on your property. We mow that section every time we test and observe how the Green Grippers perform. This test is as important as it gets. Click Here for Videos and Pictures

New vs. 9 Month Gripper
Green Gripper Wear Test: Traction After 9 Months and the Design Advantage of a Thick Outer Wall

As you can see, the used Green Gripper on the right shows signs of wear on the treads. This Green Gripper lasted 9 months of testing. The treads provide traction even after they’re worn down. The lawn mower may lose a small percentage of grip, especially on uneven terrain or wet grass, after time. That’s why we 3D Print the Green Gripper Wheel Attachments with an Outer Wall thickness of 29mm.

Green Gripper Wear Analysis: Balancing Durability with Traction

This image reveals wear on the Green Gripper’s outer wall, with some flattening of the ridges. This naturally raises concerns about potential traction loss. Here’s a breakdown of key factors to consider:

  • Usage: The frequency of use and the type of terrain, like concrete, will affect the Green Grippers’ outer wall. Even after the Green Gripper has encountered significant impacts the function remains intact. Frequent use on concrete will accelerate outer wall wear compared to green surfaces.

  • Severity of Wear: Determining the extent of tread wear is crucial. Are the ridges simply flattened, or is there deeper wear exposing the base layer? Significant wear can lead to a more noticeable decrease in traction.

  • Manufacturer Recommendations:

  • Consult the Green Gripper for information on expected tread life and replacement guidelines.

First Model of Treaded Lawn Mower Wheel Cover
From Mardi Gras Leftovers to Market-Ready Marvel: The Green Gripper’s Humble Origins
The Green Gripper’s journey began in a most unexpected way – with a dash of Mardi Gras magic! Here’s the story behind this innovative lawn mower solution:

A Spark of Inspiration: Some leftover purple filament with gold flakes, intended for Mardi Gras, became the unlikely leftover PLA. Our old self-propelled lawn mower needed better traction, and a solution was born.

From Prototype to Progress: Wheel measurements were taken. We fired up Fusion 360 and the first Treaded Lawn Mower Wheel was printed. Success fueled the creation of a second set of wheels, this time in a more practical black PLA filament.

Prototyping and Refinement: Recognizing the game-changer potential right away. Three different wheel designs were tested within a short timeframe. This rapid prototyping has led to the current, design ready to take the market by storm.

The Bandit v1
Green Gripper Tread Optimization: Balancing Traction and Efficiency


Designing the perfect Green Gripper tread faced challenges. The first attempt in Fusion 360 made the tread too thick.

We then took cues from the “Bandit v1-4” design. Our strategy was simple:

  • Refined Tread Pattern: We found that by tweaking the pattern, we could make the tread thinner without losing function. This went beyond just cutting groove depth.

  • Optimized Spacing: Instead of thinning the lines, which reduced traction and caused mud buildup, we spaced the treads out. This surprising move improved even rolling and deep traction.

The Tank v1
The Tank: A Bold Experiment in Green Gripper Design

The Green Gripper’s development journey wasn’t without its detours. Enter “The Tank” – a radical design concept that pushed the boundaries of functionality:

  • Extreme Design: This two-piece friction lawn mower wheel cover embodied an “all or nothing” approach. It boasted a heavy build with a shallow tread design.
  • The Screwless Dream: A key focus was achieving a secure fit without the need for screws. While it initially demonstrated promise, the dream turned sour. Sun exposure caused the plastic to expand, leading to the dreaded “torquing out” and ultimately, failure.


While The Tank itself never reached its full potential, the lessons learned from its creation proved invaluable in shaping the Green Gripper’s future iterations.

We tested them on concreate and stones and they still did well

The Green Gripper isn’t afraid to get dirty. In fact, it thrives in the dirt! We put it through a grueling nine-month gauntlet designed to simulate the harshest yard conditions imaginable. Here’s a breakdown of this epic test:

  • The Gauntlet Begins: On August 14th, 2023, the Green Gripper embarked on a relentless mission – to conquer our toughest test yard.
  • Nine Months of Punishment: For an unforgiving nine months, the Green Gripper battled the elements. It soldiered through until June 12th, 2024, facing every challenge we could throw its way.
  • Retirement and Reflection: On June 15th, 2024, the battle-tested Green Gripper will be decommissioned. A thorough analysis will then commence, allowing us to glean valuable insights for further refinement.

Our commitment to continuous improvement is unwavering. By keeping the doors wide open throughout this process, we ensure the Green Gripper evolves into the ultimate lawn mower companion.
