I am looking at possibly removing my exhaust to get at the engine better for cleaning it, and also maybe putting some high temp on the muffler.

It is pretty clear that the studs and nuts are VERY rusty, (funny, because the rest of the tractor has hardly any at all) and I am afraid they will not come of without a fight. Should I just leave it and deal with it as is? What is the process of fixing/replacing this were I need to remove the muffler?

 

It seems to run really well, so I don't want to dig into it too much, but I want to clean it up to give it a fresh start. There are a few broken off shroud bolts (how do you break those!?) that I need to get at and replace.

If your muffler is in decent shape, I would leave it. Otherwise, judiscious application of penetrating oil and heat. I have found a 3/8" drive impact driver works well on head bolts so may work here.

 

The Kohler Command has a tendency to backfire when shutting off. This can "crack" the muffler. The remedy is to shove the throttle to full while turning the ignition to off.

      Dead 520LXI
      By Berco
      Hello all. My battery in my 520LXI was going out, the lights would come on but the engine would not turn over. I put a 1.5 amp truckle charger on the battery when i left for a 4 days trip. I come back and the same. I also noticed i left the key in the run position (the hour meter did not run). I swap out batteries and now the mower is completely dead. When i turn the key - nothing. I verify the battery it good (13.04v), negative is connected to the engine block, voltage is good on the solenoid side of the starter. I out the key to run and try to jump to see if i can start and nothing. Not even a spark. I have used this mover for years and has 500 hours. Could the ignition switch or brake switch be bad? The seat switch is jumped.What else could cause my mower to be dead? Thank you in advance.

      523xi Berco snowblower, how?
      By gfullz
      Hey guys! new wheel horse owner here. I picked up a 2001 523xi that came with a berco subframe. I happened to find a 40" compact berco that was hardly used to slap on it only I'm not sure where to start as there are no resources for this that I can find. I'm mechanically inclined, rebuilt the injection pump, injectors etc... as I purchased it non-running as it wasn't receiving any fuel to the injectors (it runs amazing now btw). 
       
      so for starters I'm going to go out on a whim here and say that this will require the mule drive or "pulley box". and I've got the rest of the parts in the picture. The parts of the subframe that look to bolt up seem so narrow compared to the hookups on the rest of the tractor. Any help is greatly appreciated.
