Title: Spikes Dawgs Dogs Bumpers
Post by: Cut4fun . on April 08, 2014, 04:27:47 pm
Just wondering what the reason is for DOUBLE dawgs on the saws. I am just guessing something to do with control of cut during felling? 

Yes I have owned many with double dogs but I am not a logger, just a firewood cutter bucking most of the time. But I do have some monster poplars I need to drop this year.

What is the advantages and disadvantages of DOUBLE over a SINGLE inner spike?

I find that two dogs keep the front of the case out of contact with the wood, saving wear and tear on the front of the case. And on some saws they allow the saw to sit upright without tipping over. I seriously think that most people that go for BIG double dogs do it because 'it makes the saw look cool'! However the big double ones usually take away 1.5-2 inches of usable bar length.

Helps keep the powerhead from twisting the bar when dogged in and laying on the saw.

Some trees like western cedar have thick flaky bark, takes a long dog tooth to get some hold for your fulcrum point.

I wondered about this too. I had a call from a dealer looking for an outer dawg for a Dolmar PS-6100, apparently it is required for wherever his customer was going to work. Of course we don't have anything as there is no provision on the sprocket cover.

You might compare a set of 5105 dogs on it. The outer dog fits under the small mount bar nuts. The 6100 is a small mount Husky bar just like the 5105 so I know the outer dog will bolt on. It is just a matter of the inner 5105 dog fitting on the 6100.

I use the extra set of dogs, mostly in areas that I can not cut down a neighborin tree(rigth of way thing) and have to use the saw at an unlikeable position. I can still get on the bark.
That doesn't happen too often, but when it does it just becomes easier.

The dual larger ones work better when the tree swells a lot or you're putting in a humboldt with the clutch cover down.

Customer tried the 5105 dawgs, they would not fit.

Correct, I just looked it up - the inner dogs have different part numbers

Still debating on it for my use dropping some monster yellow poplars on my land.   To go double or not on a 505 wild thing.

Here is what the set up would be with outer over just the inner ones I have now.

Although I have felled a few trees, I myself have never cut anything down really big.   

Having a inner and outer dawg might help if your flipping the saw to cut it from both sides.

Kevin those dawgs in your picture would be plenty big enough to do what you need.
