Title: 7900 update
Post by: Tractorsaw1 on December 08, 2017, 12:29:27 pm
Just wanted to say thanks to Kevin, Nate, & Mike Lee for helping me out on this rebuild.  I picked up a 6400 that had a bad crank & rebuilt it.  Found some used 7900 parts & here it is having some fun.

I have a couple 7900's. They are excellent for full grown tree work.

One I bought new as a 6400 and I put a 7900 cylinder and heavy duty air filter on it. It originally had a catalytic muffler which I changed out.

The other was originally a 2006 tree service ground saw 7900 and I up-dated it to 2009 setup with heavy duty air filter and the two saws look alike and both run good.
