Stack Pictures
 

Another post somewhere showed a block crack around the exhaust port area, which may have been caused from a stack installation that was poorly supported.

I'm not sure if my support is a "cure" for stacks, but it should help with block cracking concerns. The plate is 1/4" aluminum, note it's supported underneath by flatstock to where the Quietline lower muffler shield is attached to the block. (The block is from a 1650)

The stack pipe is made of scrap stainless steel swimming pool ladder pipe I polished. Too bad the engine ran "lean" and "blued" the pipe before I had a chance to drill out the main jet in the card to richen it up a bit.

It's also got the insert muffler inside the pipe as I mentioned on the old forum.

This tractor started off as a 149, but now I guess it could be considered a 169 with the K341. It's been outfitted with the Cat 0 conversion many years ago. Cat 0 implements collected are a rear blade, box scraper, landscape rake, and a draw-bar for the trailer ball. The landscape rake challenged the Cat 0 lifting capacity (due to long length) until I shimmed up the implement relief valve spring, fortunately, the pressure was still within the range of the factory spec. Over time, I had to re-enforce some the the Cat 0 setup here and there, one example replacing the lift rod connections to the lower lift arms (hair pins kept breaking) with coupling nuts with 1/2" bolts welded on the side. Since the Cat 0 setup has so much travel, it's nice use it with the draw-bar/trailer-ball to pick up trailers, without getting off the tractor!
To balance the tractors weight with heavy rear implements, I added a homemade front suitcase weight rack. To aid steering, retrofitted a later model steering box with an additional turn lock to lock. Upgraded front wheels/spindles to 1".
Converted the generator/starter to ring gear starter and alternator, with the QL wiring harness. It's been wired for an electric PTO, but haven't installed the PTO clutch yet. Note with oversized washers, the QL PTO switch fills the cigarette lighter hole nicely.
A couple of years ago, it snapped a rear axle while attempting to free up the stuck Cat 0 box scraper in extreme heavy clay mud, by rocking the tractor back and forth. Then upgraded to a later model QL rear with internal brake, and retrofitted it with a fine spline later model differential with 30mm axles and axle housings to match. Had to have one of the axle housings machined to work with the IH cast iron case. Internal brakes allowed for inboard mounting of additional wheelweights too. Tractor uses include ground, gravel road leveling and finish work, cleaning up rough grading left by larger equipment, trailer hauling and jet ski launching.

Good lookin' Cub. Quality work it seems!

Nice looking 149! :beerchug:

Thats a lot of work you have done to the 149 or 169 Mabey you should call it a 1469 with all the changes you have made. Either way thats some beautiful work you have accomplished. :IH Trusted Hand:

Thanks
 

Thanks everbody! It never ceases to amaze me on what this old tractor has done over the years!

I agree drysumpjet. These are some of the tuffest pieces of equipment ever build. I am always amazed that after 30 almost 40 years that mine will still move about anything you hook it to.

:IH Trusted Hand:

drysumpjet,
Very nice work,I dream of finding a 16 horse single,if there is such an animal, and putting it in my 123,a bit hot rodded,with a big old stack!!!Guess ill have to know if the 1650 had a single in it!!Oh and find a 16 horse in california!!

Jason, the 1650 used the K341AQS (flywheel starter) one lunger and the 169 used the K341A (external S/G).

Just wondering, from a newbie, what is the thing about stacks? I have seen a bunch of members' pictures with stacks mounted on their Cubs, but they're also always talking about problems with cracked exhaust ports. Is it just a matter of looks or is there a real performance issue?

By the way, that's a great looking 149/169. Just getting started on my 1650.

That is by far one of the nicest Cub Cadets that I've ever seen!
Awesome!!! :High5:

For me it's two fold. The original muffler on the K161 shoots right out at the loader frame and leaves a little black soot. The straight pipe does away with that issue and just plain looks cool to me. And only cost me $5.00. So I guess it's a 3 fold reason. Performance, looks and cost. Oh yeah, it's sounds cool too. So 4 reasons now.

There is also very little weight with just a straight pipe. Now of course something could grab ahold of it and do some damage, but that's a risk I'm willing to make.

I agree, the stacks look really cool and they give a cub, the big tractor look :beerchug:

Here's the stack I made for mine. It's clamped to the muffler so I can remove it quickly if I need to.

Looks good! Sweet tractor....you have a fertilizer spreader on your sleeve hitch? nice shop by the way!

Great job, IHinIN! Your 100 looks tough. :ThumbsUp:

Thanks guys. The fertilizer spreader is going to be used as a salt spreader. It's bolted to the tractor using 2 of the fender/seat mount bolts and 1 thru the hitch hole. There's pics of it in the homemade attachments thread.

IHinIN,
Nice job on the stack.:beerchug:

OK, where did you find your pipe for $5.00??? Or do you have access to a muffler bender? I ended up cutting apart an old small block chevy header for my stack...and it is one of the louder stacks I have heard for some reason.

I stopped at a muffler shop and he bent some tubing and sold it to me for $5.00. He put two bends in it for me too. It was a short piece in the scrap bin he had laying around. He was slow and had his Crapsman in the shop working on the Tecumsah rear end. We chatted tractor for a while. That may have helped with the price.

Oh yeah, mine's loud and throaty too. I keep it in a small 10 x 12 building and when you fire it up it echos pretty nice in there. Kind of like some custom bikes with loud pipes. The last show I was at some guys were standing around my tent and letting their boys climb around my stuff not caring what happened. I went over and fired up the Cub and pointed the exhaust right at them and revved it up and moved the tractor around a little. I think they got the idea I wasn't real happy with them.

Mine has the same side exiting exhaust at the top you have.. I wonder if that is why it is so dang loud, being able to focus the exhaust at a certain point instead of straight up into the sky.

Mine was too loud for me, I hang a quiet line muffler off it when I am using it at home to keep the neighbors happy. It is only held in by a bungee so once in a while they get to hear the sound of raw power..lol. :biggrin2.gif:

SWEET! very nice work,thanks for:Cub3: shareing!

Ive got $35 in the stack on my 149, $30 for the muffler and $5 for the bend at at local place, its very quiet because of it comes off the stock muffler.

Here's the stack on my 100.

Those look really cool but I hope you guys are bracing them properly...that's a lot of mass flopping around out there. I'd hate to see somebody get a cracked block from having the exhaust port carrying all that weight.

all the weight from mine is supported by the stock exhuast mount on that heat shield

I'm not sure that's enough...take a look at drysumpjet's initial post in this thread. What he did was overkill for a straight pipe, but looks to be very strong. An excellent solution, in my opinion. That OEM muffler shield is pretty flimsy and isn't designed to have all that other stuff hanging off it. The exhaust port is carrying some of the load, too.

Those F-cub mufflers aren't particularly light.

Overkill yes.....but sooooo cool looking!!!

Stack Update
 

I have put lots hard hours on this tractor, mainly rear blade and box scraper work, requiring lots of rough ground travel. Nothing cracked, nothing loose, all good. I'm not regretting the overkill bracketry a bit, it's very solid, the key was to secure the pipe to the bracketry with a muffler clamp.

I did update the insert muffler, I had Ken at Car Chemistry www.carchemistry.com make me up a custom legnth insert. Orginally, it was a 6" insert, now it's got a 12". Ken will make any legnth insert you want.
It actually idles and wide-open/no load reasonably quiet, but when loaded, it still barks!

Thanks again for the Kudos!

Joe

ACecil- tuff looking tractor! beauty is in the eye of the beholder! i lean with Matt G. on the fears of stacks. but hey, they do look cool! and i do favor a more quiet 71. i'd like more of a drag-style exhaust pipe. :bigeyes:

Thanks John! My buddy installed it on the tractor, before I got it. The stack has been on there for five years now. :beerchug:

Stacked pics
 

after seeing ACECILS 100 with a cool stack thats for me.... plan one on my lil 70 as well looked this am and i can make a 1/2 sq stock brace and bolt it to the frame under the elbo and it will support the stack pipe love the look and seeing the flapper poppin as its runnin...agree gotta be careful with limbs catching it but i keep my cubbs out of the trees:beerchug:

My cousin, a third generation dairy farmer, always mounts his rain caps (flappers) facing him. (backwards) He gets a lot of flack from people that it's wrong. But when he's mowing the back swath, he never gets caught on the low hanging branches. Sometimes it pays to go against the grain. :bigthink:

Finally
 

As last, I got my stack put onto my 122. Should have had a better back ground for taking the picture.

Attachment 2969

Now you need to fire up the BBQ and invite us over! :)

Forget the stack check out those wheel weights!. What the heck do you do with your 122? My stack comes out the other side.

Took my stack off...too many trees...

I love that mounting plate, nice piece of work. Love all the stacks pictured here, now for my 1200 stack... Gotta think on it, but will happen soon.

Methos:
Don't let those wheel weights fool you. They're home made by using sonna tubes and concrete. They only weigh about 35 lbs. each. They look heavier than they are. So far, I only snow plow and haul fire wood. The sleeve hitch goes on this weekend and I hope to order a plow soon.
