I tested a loftness CC against my timberax just to make sure I had the most effecient head. Timberax's are the most effecient and best cut up to about 6" on hardwood and 8" on softwoods. After that the timberax's effeciency drops off quickly and a carbide toothed head becomes the more effecient choice. My head cuts grass better than any bushhogg. My FIL uses one for me some and a landscaper said he could mow behind me but not the bushhogg. My head can also do in one pass what it takes two or more passes of a carbide to get finer chip sizing.
For those running a carbide head when you engage a downed tree and start over it to process the head will sometimes throw the tree out under the tractor without fully mulching it. A timberax rotates opisite direction and picks the material up off the ground and pulls the tree into itself much like a
chipper does. Once the head has grabbed the tree its done!!! It you would like look at our web site
Trinity Mulching - Atlanta Georgia Mulching Company and the first video will show this.
Like I've stated before for general brush and trees up to 6-8" the timberax is a tough head to beat. It has the most effecient use of availible hyd. h.p.
But this does come at a price because of the blade sharpening issues and the size limit of material you may encounter. Oh yea. NO ROCKS
I do know that carbides shine in different environments and for that reason i would like to have a second mulching head that would be a carbide just for such jobs that require cutting larger material.
I'll just cover this point quickly. Loftness will size the pump to the tractor at no additional cost. My head also has the "anvil" that is supported by a shelf and have encountered extreme conditions and your not going to hurt the drum or the shear plate. My head weights 2500lbs of solid steel. They built it to handle anything,
My head has the push bar with the hooks. It is heavy gauge square tubing and have pulled 20"+ trees with it with no damage and no strain. I use these hooks qiute often to pull material out from between trees that are close together. They are a valuble tool. I have also demoed heads with pushbars that were too short and one could get into trouble qiuckly that way also.
But like was stated earlier you buy the head that best suites the jobs your planning to do. Rough cut with higher production rates the general winner is the Fecon with most others running close behind. For finer mulch size and clean site I believe the timberax would prevail here.
