The Importance of Properly Classifying Stump Grinding Operations

Author, Rory Anderson, Account Executive, Rancho Mesa Insurance Services, Inc.

Almost all tree care companies’ operations include stump grinding. Stump grinders are powerful machines that are designed to chew away and grind a tree stump down into little pieces, after a tree has been cut down. The operator guides the blade over the stump to take it down below ground level. Because stump grinding is done from the ground, it can create some confusion for tree care companies on how to properly classify this exposure for workers’ compensation insurance. A lot of tree care companies assume that because the employee operating the stump grinder is on the ground, it should be classified in 0042 – Landscape Gardening, which is more cost effective than classifying them in 0106 – Tree Pruning. However, this assumption is incorrect. It’s important to understand how and where to classify this exposure, so you’re not setting yourself up for an issue at the audit.

The Workers’ Compensation Insurance Rating Bureau defines all class codes to help companies classify specific operations. Let’s look at how they define 0106 Tree Pruning, Repairing or Trimming.

0106 Tree Pruning, Repairing or Trimming
This classification applies to pruning, repairing or trimming trees or hedges when any portion of the operations requires elevation, including but not limited to using ladders, lifts or by climbing. This classification includes clean-up, chipping or removal of debris; stump grinding or removal; and tree spraying or fumigating that are performed in connection with tree pruning, repairing or trimming. This classification also applies to the removal of trees that retain no timber value.

According to this definition, a tree care company must report stump grinding in 0106 if the stump grinding is in connection to the 0106 tree work that they performed. Even though the stump grinding operator is working from the ground, they must be classified as 0106 because the stump grinding is performed in connection with the 0106 tree work that they performed.

For example, a specific job calls for the removal of four valley oak trees. The arborists from a tree care company spend the morning climbing, trimming, and removing the four trees. A few hours later, the ground crew grinds all four stumps down using the stump grinder. Per the WCIRB classification definition, the ground crew who are operating the stump grinder must be classified in 0106 because it was in connection to the 0106 tree work that they (the company) performed.

The WCIRB also states that “stump grinding performed for other concerns on a fee basis and not in connection with tree pruning, repairing or trimming at a particular job or location shall be classified as 3724 – Millwright Work.”

To clarify, a tree care company may report stump grinding in the 3724 Millwright Work class code if it has no connection to 0106 tree work. So, in other words, you may only report stump grinding in 3724 if the job calls for only stump grinding.

For example, a homeowner has a stump in their backyard and calls a tree care company out to grind the stump down. This work may be classified in 3724 Millwright Work only if the tree care company did not trim or remove the tree first; they simply showed up and grinded the stump.

Having an insurance agent who specializes in the tree care industry is instrumental in building trust so that this critical information is communicated to you properly. With this information, you can have the confidence that you are reporting payroll correctly and avoid classification issues that can potentially arise at the final audit.

Choosing the Right Classcode: A Guide to Distinguishing Tree Trimming from Landscape Work

Author, Rory Anderson, Account Executive, Rancho Mesa Insurance Services, Inc.

Many tree care companies perform work that could be classified as “landscape gardening.” The risk and exposure associated with this class code is minimal compared to those associated with tree trimming. Without the additional tree care exposure, landscape gardening workers’ compensation insurance rates are significantly lower than tree trimming rates. Common questions we receive from our tree care clients are:

• What is the difference between the two class codes?

• I’ve always only used 0106-Tree Trimming, is it possible for me to use 0042-Landscape Gardening as well?

• How can I differentiate which specific operations are considered landscape gardening and which are considered tree trimming?

When more than one classification applies to operations that are closely related, it is important to understand the boundaries of each classification. Let’s take a look at how the California Workers’ Compensation Insurance Rating Board (WCIRB) defines both class codes:

0106 Tree Pruning, Repairing or Trimming

This classification applies to pruning, repairing or trimming trees or hedges when any portion of the operations requires elevation, including but not limited to using ladders, lifts or by climbing. This classification includes clean-up, chipping or removal of debris; stump grinding or removal; and tree spraying or fumigating that are performed in connection with tree pruning, repairing or trimming. This classification also applies to the removal of trees that retain no timber value.

0042 Landscape Gardening

This classification applies to the construction, maintenance, repair or installation of landscape systems or facilities designed for public or private gardens or other areas in order to aesthetically, architecturally, horticulturally or functionally improve the grounds within or surrounding a structure or a tract or plot of land. This classification includes the preparation and grading of plots or areas of land for the installation of landscaping; pruning, repairing or trimming trees or hedges when none of the operations at a particular job or location require elevation, including but not limited to using ladders, lifts or by climbing; or chipping operations performed in connection with landscape gardening. This classification also applies to spraying or spreading lawn fertilizers or herbicides, or weed abatement for fire hazard control purposes.

According to these definitions, a tree company may be able to use the 0042 landscape class code at specific times. However, when any of the operations are off the ground, that payroll would be classified in tree trimming 0106. Also, any type of work that is associated with the tree trimming (e.g., clean-up, chipping, stump grinding, etc.) will also be included as 0106. Here is a quick real-world example that will help to clarify.

A tree company has 10 employees that worked on a specific job to trim a large Eucalyptus tree. There were only two workers that actually climbed and trimmed the tree, and all the rest of the employees worked on the ground to clean up the limbs and branches that were being cut and fell from the tree. All 10 employees must be classified into the 0106 class code because the ground crew operations were in connection with the tree trimming, where the climbers were operating off of the ground.

The next day, on a completely different job site, the same tree company with 10 employees worked on a new job to trim a handful of 8 ft Japanese maple trees. For this job, all of the work was performed from the ground and there was never a point where any of the workers operated from elevation (e.g., ladders, lifts, climbing, etc.). Three of the workers trimmed with pole saws from the ground, while the other seven employees cleaned-up the debris and used the chipper. All 10 of the employees could be classified into the 0042 landscape class code because there was never a time where a worker left the ground to trim.

Properly documenting and maintaining valid records is critical in order for your company to utilize both class codes properly. Without proper documentation, you could be setting your company up for a large additional premium owed at audit.
