Update

Seems I have been ignoring this blog.   The foundry stuff have moved to https://nmlfoundry.blogspot.com.

It is mid August 2021 and the weeds on our 2 acres have gotten away from me.

The DYT4000 has a blow head gasket since last year.
Have the DR Trimmer working but stops after a while seems to be overheating.   May take it down to the car wash and clean the fins.  They are open but may have a coating of weed goo that is insulating.

The BX has several small hydraulic leaks but they add up and at $60 the hydraulic fluid gets expensive.  A while back I started changing the old leaky quick connectors for the loader with new ones that are incompatible with the old.  Still have one connector that has not come loose.  Thinking maybe cut slits in it with the dremel and peel it off.  But it also looks like the hose end where the quick connector screws on is bad.  So will try to get it off on the other end and replace the hose too.

The old push mower has not been working.   Spark problem.   Thinking next step is to pull the new coil again and file the coil mounting posts down to new metal.   

Update:
The DYT4000 head gasket was good.  Should have done a leak down test.  Now it does need a head gasket.  Have 2 gaskets in stock but are the wrong number.   Not sure what that is about.

On the BX replaced the 3 steel lines that connect to the loader.  Removed the line with the stuck connector and put it in the vice.    There is still one connector to chance on the loader.  It is still leaking under the floor pan.  Oil on the radiator screen.
  
The mower works great after freshening up the coil mount posts!
