I've got a mulching head built by Alamo that I've used on a half dozen or so machines with flow between 18 and 22 gpm. It's originally built for an excavator since it's only 48" wide, but has an adapter plate on it for the skid. I bring in limbs with the dump trailer and drop them in the corner of a field, then use the Alamo to shred them up...saves a lot of hand work. Picked up another Tl120 and decided to try the Alamo on it even though it's only maxes out at 15 gpm. I was pleasantly surprised it only took 45 minutes or so to grind up 7 dump trailer loads of 4" and smaller limbs. It really throws the chips a long way out in front of the machine too. Backing over it is more productive than going forwards: All done mulching: Pushed up the debris with the skid and bucket: Question: with every machine (bobcat, nh, cat, takeuchi) the head will sometimes make the auxiliary pump vibrate. I can stop the vibration by either throttling down or by putting a load on the head. Any one else have similar experiences?
