Tub Grinder with Operator

A tub grinder is open-topped: a loader tips material in and the mill takes it. That makes loading fast and tolerant of awkward shapes — stumps with soil still attached, root balls, tangled storm debris — which is why tubs dominate cleanup and clearing work.

A horizontal grinder feeds material through a controlled infeed conveyor. It throws far less material, handles long stems better, and produces a more uniform product with less contamination, which is what you want if the output is being sold as mulch or fuel.

In practice: dirty, mixed, stumpy material goes in a tub; clean wood destined for a product goes through a horizontal. Describe your material and let the operator tell you which of theirs is right.

Grinders consume material faster than most people expect, and their economics depend entirely on staying fed. A machine waiting on a loader is burning fuel and an operator's day for nothing.

That means a loader or excavator with a grapple dedicated to the grinder for the duration, and often a second machine moving finished product away from the discharge. Plan the whole circuit before the grinder arrives.

Say in the job post whether you are supplying the feed machine or need one. Some grinder operators bring a loader, most do not, and discovering that on the morning costs a day.

Grinders throw. Metal, stone and wood come out of them at speed if contamination gets in, and the exclusion zone around a working machine is measured in tens of yards, not a few feet. Sites need space, and people need to be kept out of the discharge line.

Contamination control is the practical version of that. Wire, fencing, nails and stone in the feed damage the mill and create the projectiles — a tidy feed pile is a safety measure as much as a productivity one.

Noise, dust and fire risk all need planning too. Ground material self-heats in large piles, and neighbors notice a grinder long before they notice a chipper. Consider hours of operation and pile size before you start.

Day rates with the operator included, weekly rates on longer projects, and mobilization charged separately and substantially — these are heavy machines that need proper transport. Some providers price by tonnage or by volume processed instead, which suits a defined pile.

Fuel is a real number at this scale and is often billed separately. Wear parts — tips, hammers, screens — are consumables the operator carries, but heavy contamination that damages the mill is a conversation worth having in advance.

Rates and terms are agreed directly between you and the provider. Treelign holds no payments and takes no commission; settle rate basis, fuel, mobilization and the contamination position before the machine is booked.

Post the job with the material type, the estimated volume, the site and its access, whether you have a feed machine, and what you want the output to be. Operators whose radius covers you are alerted immediately.

Each service on a job carries its own crew size, so a grinder can be hired alongside a wheel loader, hauling and a chipper on the same job, each service filling independently.

For a clearing or cleanup project, post the loader and the hauling as separate services on the same job. They are usually different providers, and posting them together is how the whole circuit gets staffed rather than in three rounds of calls.
