Hell all,
In Australia we originally had the Yuba spark arresters on our tractors and I want to refit one to my Power and Super Major tractors.
A couple of months ago I found on a farm dump an old rusted one that I want to use as a sample to make a new one, & I thought that others may be interested too.
I have yet to take measurements but that should happen soon.
Mike, I'm interested in seeing a picture of your old one and how it was mounted etc, because I didnt realise they were made to fit majors. Also why were they only fitted in australia? Is it to do with the different climate, i.e, very dry?
Oh yay, look, another seized bolt! Lets get a hammer.....and some kano.....and some cider!
When I was looking for a new muffler for my tractor I ended up buying a brand new Yuba spark arrester. As far as I know it is a legal requirement to have a spark arrester fitted if you want to use your tractor on total fire ban days in Australia. The design has not changed much, only the brass cap seems a little smaller now.
Regards, Frank.
Real tractors don't need tin work to be beautiful.
G'day one and all.
This is my first post -- and anyone kind enough to call me a 'newbie' will make me feel young again.
I and my partner farm about 700 acres in the sou' west of Australia in a place called Kendenup. We have 2 tractors -- a Deutx DX110 4x4 and a workhorse SMD circa 1960 which I am slowly rejuvenating.
Spark arresters.
Mainly used in the mid and top end of Oz. In the lower quarter [about 500 Ks wide] of my State I have not glimpsed an arrester fitted to a tractor.
Fire bans are usually declared here at the end of the spring rains, about October, which means you cannot light any fires without special permission. Also, any work in paddocks useing petrol/diesel engines, hand held or wheeled, must have in attendance a fire truck or trailer with at least a 1000 litre water tank on board.
During the hot, hot months, generally Jan -- March, if the temp. starts climbing above the mid 30s and into the 40s C then a complete fire ban is issued and no vehicles are allowed to work or travel on the land. Having seen the devastation a bush fire can cause, only a fool would ignore a total ban.
A question, please. The good book says that the SMD filler/level plug for the steering box is on the left hand side -- but I'm damned if I can see it. Help appreciated!
Pavel.
The steering box level/filler is a hexagon headed plug on the side of the box, above the gearbox filler, right where the column joins the steering box. We used the injector spanner to remove it as the head size is 1/2" AF.

Attached is photo of the three different Spark Arrestors manufactured by E. Brockman & Son under the trade name Yuba. One the left of the photo is the early type Spark Arrestor which was used on the Model N with a straight pipe and the E27N it fitted on top of the Burgess Sausage. The centre Spark Arrestor is for the New Major series from Mk1 to Super Major. And the Spark Arrestor on the right is from the E27N. The only difference from the E27N and the New Major is the length of the inlet and length of the outlet. (Outlet on the E27N was 4 inches - Outlet on the E1A was 17 inches). I am pretty sure that the Dexta used the New Major Spark Arrestor as well.
If anyone needs to make one, assuming there is no copyright issues, here are some measurements,
I picked up an old rusted spark arrester from a farm dump and hope to make one myself, the tricky part will be the
4 fluted spiral in the middle that uses centrifical force to throw sparks to the outer part of the muffler.
Thank you Brian -- lube in the st.box has made a hell of a difference when the FEL bucket has half a yard of gravel in it.
Thanks too to Dandy Dave and Halloween. Whilst I've only recently registered, I've been an avid reader of this site for some years and am struck with the friendliness and help to be found here.
I must say, Mike, I thought your draughtsmanship very professional. However, the internal workings of the arrester are a little beyond my unsteady hands and weakened eyesight capabilities.

The Dog Leg on some Yuba's was the result of 2 different Manifold Outlets. Also, the Manifold Outlets on Australian tractors had the 2 ears and bolt to spark proof them.
If you cut your old Yuba up and remove the cone, you will be able to use it again as they were cast or bronze, and didn't seem to come to any harm.
Dandy Dave!
