    We just picked this trencher up for free from a company where the corporate top brass said "clear out all the junk" & we thought it was better than junk, so we loaded it on our boom truck & brought it back to the yard. We have no experience with the Davis/Case trenchers, but thought it is worth trying to check out everything on it & try to get it going. Any idea how old it is? The Ser # is 1140513. It looks to be in decent shape & we will not waste any time in finding out!

    Does anyone out there have one in working condition that can comment on this model?

    Well, we worked on it for an hour today & Tony got it going! Not bad for a free machine!

    Anyone know how we can adjust the chain out to tighten a bit?

    I had a look & did not see one. Is the grease fitting on the part near the tip that moves in/out, or on the fixed part?

    It's on the end, on the part that moves in and out. Should be next to the roller, on the side at very end. It goes to a cylinder, much like tensioning mini ex tracks. And like that set up, they can blow seals and not hold tension. Going off memory here, it's been 25 years since I dealt with these. 25+4, 30+4, DH4, DH5 etc.

    Well, we tried it out for the first time actually this morning, as we have a trench to do for a new electric service to a building here on the property. It has been about 10 months since it ran & took a bit of coxing to get it going, but once running it worked ok. So far so good.:)

    I do have a Operator manual for sale for the 40+4 trencher if interested. jc
