Forest Thinning/Fuel Reduction 

Grinder and excavator 

The horizontal grinder and excavator only work as a pair so they are hired out as a pair. We have our own expert operator who operates our machinery. The price includes the operator, fuel, and regular wear and tear on our machine.  

For large jobs (over a weeks worth of work) we will split the trucking costs to transport in the machinery.  For smaller jobs the trucking costs are on the hiring party.

Damage to the grinder from contaminants in your slash or brush (as chokers, choker bells, chain, or other damaging items) will be paid for by the hiring party. Our operator uses a professional-grade Fisher metal detector prior to grinding, to lessen risk of contaminants reaching the grinder. 


Some tasks  only require the excavator, such as brushing with the brush head, shearing brush with the shear, spreading or piling chips on your site, re-decking logs, or other excavator tasks. 

Additional Information

In California, all commercial forestry work is regulated by the state agency, CalFire, which requires that registered professional foresters (RFPs) analyse the site and apply for the most appropriate permit/exemption. The actual physical work must be done by a licensed timber operator (LTO). 

These professionals are, with few exceptions, needed even when the purpose is not commercial, as when forest owners desire to treat their lands to lessen wildfire risk to them, without selling the resulting forest products. CalFire permits (some of which are called 'exemptions') or, depending upon location, county permits are needed. Only the defensible space exemption application, for work within the smallest distance from a residence, may be prepared by the landowner or his/her LTO. An RPF must prepare the permit/exemption application, otherwise. 


Counties vary in their regulations regarding forest reduction, forest thinning, and defensible space creation, but county control only applies in limited situations (see Regulatory Summary chart on this site). 

Where the work to be done involves urban settings and locations very close to structures, and the products of the work are non-commercial, an arborist, rather than and LTO, may be the correct service provider according to CalFire. 

Because each potential work site is different, our potential client should hire an RPF to discover what regulations best apply to the site, and to prepare the CalFire and/or county permit applications. We at MaxMix meet with you on site, to make a rough estimate of equipment and labor type for the work needed. We then share information with the RPF, if you desire, and the RPF then applies for the appropriate permit/exemption, which can take several weeks. 

Contact us to learn more we can provide a list of reputable RPFs in Humboldt County, who are willing to do these forest health management/fuel reduction jobs, which are typically smaller jobs. The choice of the RPF is the client's since he/she pays for the RPF service directly. Once you, the landowner, has a permit/exemption in hand, MaxMix's LTO and crew can do the work you need.
