Fixing the second hand mulcher.

11 Nov


I’m adding the mulcher to the blog because I have a feeling this is going to be an ongoing saga. I bought the chipper mulcher (COX model 7204h)for $150 second hand. One of the three rotor arms was bent over, that’s the bent peice of flat bar at the bottom of the photo. The air chisel and a hammer freed the bent rotor arm from the welds that weren’t already fractured. Six millimeter plate was never going to hammer back into place nicely while the rotor was still attached to the engine. The seller’s optimism that a good hit was all that was needed was probably to hide that the rotor is well and truly seized onto the engine shaft. Oh well. Also well that ends well. All the old welds were ground back and with the new bar everything welded back into position.

      I didn’t manage to get the whole rotor off the shaft. Hopefully you have better luck. I tried holding the whole mulcher by the rotor and striking a bolt fitted in the shaft. I used a propane torch to heat it up, penetrating oil, but no luck.

    dont know what that bent plate is for shouldnt be on it. i just got my one fixed it the best thing i got itbhad no hammers on it the while plate was crap and bent i bought a wole new plate costs 700au i also paid them 200 to put it on to change it the only way to get them off is to cut the whole thing off the sharft without cuting the sharft oh yeah new plates dont look like that one. they fit better and cut better you have to upgrade theses chippers to work properly
