I added the drag back fingers that are on the LT70 to my 40 Wide head, After some light welding they work great! Make for a much better board return system instead of just using the drag back arm by itself. @YellowHammer

123maxbars,
 Now you will have to add the @Yellowhammer Dragback Shelf. Looks like a worthwhile mod. Do you think it would be less useful if you had the walk along instead of the command control console? Thanks for the video.

I think so, I would add it if i did not have the command control,

It works best with the stationary console, and it's a five minute mod.  Simply weld a narrow plate across the bottom of the dragback arm and you'll have complete control of dragging back the board and putting it where you want it on the table.

The stock dragback drops the board as soon as it clears the cant.  You can see that in @123maxbars excellent video.  This mod keeps hold of the board and allows it to be carried all the way to the end of the travel of the head, so to drop the board on the end of the outfeed table.  It really does work for such as simple thing.

Robert, Nathan, Do ya'll always us the dragback?  I often square up a cant and just cut to the deck, using the weight from the upper board to keep the lower boards from moving.  Then I raise the stack on the toe boards and move them with the tractor.

I can tell you I use mine all the time.  WM ships the 70 with a pin to hold the actual dragging fingers in the up position should you not want to use it.  I don't think I have ever put that pin back in.

I always use mine.  It allows me to inspect each board as it come sliding by me
Also, the goal is to not have to touch the board so I bring them all the way back and off the end of the dragback table directly onto the awaiting pallet.  It doesn't always work perfectly but especially with big slabs I try not to handle them but let the machine do the work. 
That's why I like the dragback mod so much. Big reward with little effort.

Ideas for a cushion to put on the table for back end of slab falling more than about a foot.  Whacks the mill and can break a slab. Not my idea of an orderly sawing operation.  I suppose if one is bringing it back far enough so it is tipping off the front end of the table that could reduce the fall.

Boat Bumper
Boat seat cushion (throwable PFD)....probably would get torn up too quick
old sofa cushion....I think this would be pretty good
2" styrofoam (works but breaks up)
Sawmill spare tire (too heavy)
small tire no rim
some kind of 1-2" heavy rubber pad would be nice
large stuffed animal

And how to keep the fixed table from moving...

Yup - the table could have a better system to hold it in place.  I have found that if I set it up so the end of the table is slightly elevated it helps to keep it from bouncing around.  Just a touch up, too much and you will bind the last board when bringing it back.  

I suppose an hour under there with my welder and I could come up with a latch to secure it, yet come off easily.

Pretty nasty when a too short board  falls down before it gets to the table  ::) ::) ::)

When sawing live oak or heart longleaf pine we have found diesel fuel to perform best as a blade lube.  When sawing other logs we will use PineSol, laundry soap, cotton picker spindle lube or antifreeze.  We were putting diesel in the lube tank when needed and then someone would need something sawn that did not require diesel and then the lube tank had to be emptied and refilled with something else.

Anyway, I had an OMC VRO tank lying around for decades since removing it from my boat.  I would prefer to mix the oil rather than rely on it.  It fit well on top of the mill's diesel tank and plumbed in easily to the lube line.  It does need a little finer adjustment than it currently has but today it worked well.  Even when sawing other species,

 

 

 using diesel on the last cut or two will ensure the blade is clean and will not easily rust.

The brass fittings were some I had saved after redoing the fuel supply on a 1979 Dusky center console that we used to have.

if your farm store does not carry it (in cotton country, spreading north)  i got 5 gallons for just barely more than the price of 1 gallon on amazon.

Here is one source:  LINK  I believe that there is a $9.00 flat rate shipping and you must order multiples of 4 gallons so 4 gallons + shipping would be $28.60.  8 gallons would be $48.20.

Just to verify, this is cotton picker spindle cleaner. I think the lube is like grease - someone on the forum mentioned they bought some once and it did not mix with water, but the cleaner is an emulsion that mixes with water. The "Lube and detergent" MM linked to is the correct stuff, but I guess the labeling can be misleading. Long story short, make sure it is the stuff that mixes with water.

YellowHammer

The drag back shelf holds the rear end of the slab up so that it doesn't slam on the table, and the front end levers off cant to the table as it's pulled back.  If then slab is pulled all the way back then it doesn't slam, it slides off the drag back shelf, rolls off the dragback table roller, and slams onto the pallet. I'll even drop or raise the head while dragging back, which controls the boards as they are being returned.  It's done with the anywhere hydraulics on the 70 or the mods on the 40.  It the video I have posted, you can see me raise the rear toe board so the dog boards is rolled on it instead of being dragged across the bed.  On the 70, I have raised that last dead roller a tad, higher than the kill deck, so when I'm pulling back dog boards, they are rolled over that last roller.

Sometimes I do inadvertently drop a big slab, and boom.  

My 70 table clips to the mill to keep it from walking.  Doesn't yours have the same feature?

I adjust my table rear end high so that I can drag more boards onto the pallet.  I also welded a tail roller to my table so the boards roll off on the pallet.

This is the stuff I usually use.  Notice on the bucket it says,
 "The oil that will not burn."

I would expect it is the same as yours.  

For those not familiar with the 70, the 5' table when sawmill is set up, clips to the front of a smaller table that is fastened to the frame with all-thread rod and brackets.  This smaller table and its "fastening" will move incrementally because of the heavy forces of slabs falling on it and the larger table.  Moves more if you inadvertently whack it with the front end of a board.

It is not hard to re-adjust the smaller fixed table, and it is necessary to do so periodically, to keep the tables,in their travel position, from encroaching on the front outrigger adjustment nut. And to keep the two tables parallel with the length of the sawmill-they tend to cock sideways a little as they move.

I wish these didn't move, but maybe it is necessary that they do so to avoid damage. Also, the front fixed table really needs to be kept in vertical adjustment as if it were a bed rail, to accurately saw long timbers that reach it and respond to stresses in cant sawing.

I don't know who first posted about this mod but it is one of the best mods for the arm type board return. I did a bit of a mod to the original mod and I like it even better now.



You can see in this pic the original 1" by 1/4" flat bar that I added and in the second pic you can see the triangle shaped piece added to make the shelf very reliable and positive for the job it does.  It is quite a bit wider and the edge is parallel with the cant instead of angled.
