What mulcher head are you looking at? For the money and the short life of them I didn't think they were worth it.
What type of trees and size are you guys mulching? The Fecon I had stalled and was a piece of crap and left more of a mess. I would rather put that money into another machine and push the trees out. My friend had a Fecon and it was always breaking down. He traded for another brand, but not sure which. Those Fecons don't like locust or hedge around here. I can see where they would eat pretty well with very small brushy trees and cedar trees, but there's not much of that here.
I had it on a Terex and Cat 299's. I wouldn't say it was inexperience, but you can make yourself feel good about yourself that you think you're a proHead stalling is a carrier problem, inexperienced operator, wrong size head/motor, or application beyond the carriers capacity. We mulch up to 8" diameter with the carbide hammers, 24" plus diameter hardwoods with the knives. Locust you need to run the knives for sure. The heads pretty simple with few parts to break.
I ran it on some cedars and it ate them for a snack and wanted more.Here in FL I mulch mostly pine, sweetgum, cedar, maple, and oak being the hardest. All in the 6-8" range. Did 10 acres of planted eucalyptus trees recently for a UF tree farm. That took about 12 hrs.
Keeping the belt adjusted on the mulcher is very important, if too loose it just slips on the big stuff.
