Common questions about used grinders
Horizontal grinder vs tub grinder — which is better?
Neither is "better" — they're different tools. Horizontal grinders handle dirty, contaminated, or mixed feed at consistent throughput. Tub grinders handle bulky, irregular material (stumps, root balls, large brush) more easily. Most operations end up specializing in one. We have a full comparison in our blog: "Horizontal vs Tub Grinder: Which Is Right for Your Operation?"
How many engine hours is too many on a used horizontal grinder?
Tier 4 industrial diesel engines (CAT C18, Cummins X15) are typically rated for 15,000-20,000 hours of useful life with proper maintenance. A grinder at 6,000-10,000 hours that's been well maintained is a solid buy; one at 15,000+ hours should price reflect upcoming engine work. The grinder unit itself (drum, hammers) is rebuildable indefinitely as a wear part — it's the engine that ultimately determines remaining life.
What size grinder do I need for X tons per hour?
A 30-40" diameter horizontal grinder (CBI 5800BT, Morbark 3800XL) typically processes 30-50 tons/hour on clean wood waste. Larger machines (CBI Magnum, Morbark 6400, Peterson 5710D) handle 60-100 TPH. Production drops on dirty or contaminated feed. Tell us your typical feed and we'll size accordingly.
Do horizontal grinders handle stumps?
They can, but tub grinders handle stumps more efficiently because the tub geometry holds bulky material under the hammer. If stumps are >30% of your feed, a tub grinder will outperform a horizontal of similar HP. If stumps are occasional, a horizontal with a feed roller is fine — just feed slowly.
