Scale Model Dozer Ride On For My Son

[HOTFR8]

What ever you do with the muffler just make sure it fits in with the build and suits what you have done with it to date.

I would say keep a muffler that gives you a spark arrestor. You would not want to see it catch fire after all this work.

 

[neonnblack]

Spark arrestor? Hell, i was thinking flame thrower!

 

[CNGsaves]

Spark arrestor? Hell, i was thinking flame thrower!

A little propane or CNG tank tucked in the back with a regulator could take care of that !!
Flame-thrower inside top of exhaust stack !!

This idea has got me thinking . . . . how about HEATED snow blade !! Ice-buster !!

Seriously, I'd wait until you've decided on engine covers and such. I think a smaller exhaust pipe would look better (ie skinny but include your flapper). With entire mini-dozer being custom design, just can't think a bolt on is going to work. You're going to need to BUILD it !!

My only concern on a vertical stack is that you get it high enough to get the exhaust above your head so your not breathing exhaust or having it burn your eyes. I do like the muffler you show in the last example.

no neat sig line

I was going to say the same thing. I used to have a small Simplicity garden tractor and when the stock exhaust finally fell off I fabricated a vertical stack with a flapper. It was really cool to look at, but in function all I got was a face full of exhaust which usually led to stinging eyes and a good old headache before the lawn was fully mowed. From a purely functional standpoint I would highly recommend staying away from a stack unless you are going to make it long enough to safely get the fumes over the top of your (and your sons) head.

Very cool project.I can't fathom how you have time in your life to pull this off, but somehow you've done it and it looks great.

I personally think the stack would take away from the look of the dozer, but I'm more of a streamline-aesthetic kind of guy. Are you putting on engine covers like below?

My vote is to either keep the stock muffler or do similar to a car and run a pipe back with a muffler and dump it under the chassis. This would put the exhaust fumes under the dozer and not in front of the driver. I would see if fumes are an issue with the stock muffler first.

If you do go with a stack, you may find it difficult to package the muffler without it being part of the stack like the below pics

 

[NoSloCoupes]

Just read it all....amazing build!

 

[brucer]

I bet you never have to ask your kid to clean the snow off the driveway..

 

[catsteve]

The 22's had a side mounted exhaust that came out throughout the side engine panels

like this one
http://www.cheffins.co.uk/lot/-470820-vintage-0

The old cats also had factory exhaust extensions which added about 4 feet height to get over your head when operating. They were held in place with guide wires.

What about a thin moto cross type muffler? that mounted to the side wouldn't look out of place.

great work by the way.

I have read this thread, until my eyes have bled, and this by far is the greatest thread. Thank you for documenting this build. You have done what many have dream on and never attempted. I got here by looking up on google diy tubing benders and saw your porch swing (which I may add is also a very well made piece of furniture)and saw at the bottom of the post your post the dozer build that took me a few days to read through. After a day I was registering on these forums and this is my second post. My first was just my introduction. Again thank you for documenting your build.

 

[dozerbuilder01]

where did you find the tracks from ?

Ebay. They are meant for a ditchwitch sk500

I bet after this round of snow you are wishing it was complete enough to clear the drive.

I know. I've gotten lazy with shoveling. I do a real half *** job now because I keep hoping I'll have it done soon to plow.

As long as you can't decide, here are two more options:

1. If the sound from the stock muffler is acceptable, B&S makes muffler deflector plates that bolt to the stock muffler (using those 4 threaded holes in the face of the muffler). Not knowing the engine model number, this might not be the right one but it is for an Intek engine:
   
   
   
   
   Cut off the appropriate piece of mandrel bent exhaust tubing from this J-bend and weld it to the deflector plate. You'd have the vertical stack you're after and no bulky muffler on the side of the dozer.
   
   
   
   

Thanks Bob. I definitely liked this idea the best. So that's what I did. Got a piece of tubing from Jegs and a flapper cap from Farm and Fleet and made my own flange.

Sorry, didn't take any close up pictures.

I appreciate everyone's feedback. I really have no clue what I'm doing so I either ask or try it myself. Or both.

So here's what I've found:

I like the stock muffler because it's made for the engine and it's fairly quiet. I also like a stack with a flapper cap pretty much because I think it looks cool.

I did not notice exhaust in my face while riding it today. If it does bother anyone riding it in the future, I can always take it off.

Now for the problems. First and foremost, vibration was too much (frozen ground) for the little sheet metal screws holding my pipe to the muffler. It fell off within minutes.

The next problem is the heat. The one reason why I considered the external muffler was because the stock muffler is close to hydraulic hoses and the fuel tank. I borrowed a friends thermal imaging camera and this is what I saw.

That vertical sliver of heat to the right of the muffler is the fuel tank. I didn't think to look at it from another angle so that is most likely just a reflection of the muffler. I couldn't quite get a shot of the hydraulic hoses underneath but they aren't melted so that's good. If I keep the stock muffler, I think a heat shield would help a lot especially during warmer months.

Just for fun, I took a shot of the pumps.

So I need to figure out a better way of attaching the stack if I chose to keep it. Right now, I need to focus on some other things.

 

[dozerbuilder01]

Thank you again for all of the feedback. I'm glad you all enjoy following this build.

As for my post above, it appears that I took if for a spin for the first time with the new engine and the plow. I took it to my parents house. They have more room. I can't leave you guys hanging so here is a video.

I couldn't have picked a worse day. It was cold and raining. Eventually turning to ice. I sprayed it down with WD40 to keep rust at bay. But it's not a big deal because the whole thing is going to be dipped or sandblasted.

Overall, it did really good. The new engine has a lot of power. Didn't bog down once. The smaller engine pulley brought down the top speed which is good.

I have a little bit more work to do and then I can start stripping it down for paint.

 

[fatboy99]

The Blade works well and the dozer has pretty good pushing power for its size. This has been a great build to follow.
Thanks for all the effort in sharing all the photo's and The detailed write ups.

 

[jhn9840]

This is the coolest project on GJ. Read every post since day one and just watched the video. Looking forward to seeing it all painted.

[Hghgrad]

Still amazed with the work that went into this. It's awesome, wish I had the talent to do something like this.

 

[EOC_Jason]

LOL... I was just waiting for you to plow into those pile of bricks.

Yes, you can tell the speed has come down some. I remember the old video of you zipping around the yard, that just wouldn't be safe for kids on such a big vehicle.

Porch swing build? Never saw that one! Why did you hide that in free parking! It definetly belonged here! Another awesome fabrication inncluding all the tools you built!

love the dozer build btw

 

[pertneer]

I like the new video! looks like it will have no problem moving any snow we get in Illinois. I can't wait to see it move dirt, the ground looked really froze, yet it still tried to move the uneven spots that you tried.

What are your plans, paint or powdercoat? Are you powdercoating frame?

I thought about it. My friend rode it and plowed into a pile of logs. It was fun to watch this thing move around after all of this work.

I am happier with the speed. It's even slower when I turn down the engine. The throttle control is on the back of the seat so my son won't be able to turn it up.

I'm not sure. This forum was there too at one time. When I first joined, I didn't notice the fabrication section so I thought free parking was where it should go. I had this one moved but didn't want to bother the moderators to move the porch swing thread.

Yes, the ground was pretty hard. It scraped the junk in my dads burn pit fairly well.

If the weathermen are right, looks like we are supposed to get a good amount of snow over the next few days. I will be trying it out then.

I've never been a fan of powdercoat. I'm most likely going to do paint. My dad is really good at body work and we've used DuPont for years. I can't remember if it's the Imron or Centari that's a really hard industrial paint. He's going to talk to the paint supply store that he goes to and see what they recommend.

 

[dozerbuilder01]

Here is another short video. My parents have a few hills and the area behind the garage is kind of steep. I wanted to see what it would do. With the weight of the plow on the front, it was very stable the whole time I rode it.

Here's another video of my friend riding it. Nothing too different than the other videos.

 

[machine_punk]

Duuude. That's all I have to say.

Imron was the harder of the two used quite a bit in aviation and adapted to automotive. Centari is a very shiny enamel primarily used in the automotive field. Do you think you could give us some info on the hydraulic pump and motors you used in the end. You got me itching to build something similar but completely different.

They are Parker brand hydrostatic pumps and wheel motors. I got a surplus kit from Surplus Center. It looks like they don't sell them anymore. I tried finding the link because that had the most information about them.

Looks like they sell the motors individually.
http://www.surpluscenter.com/Hydrau...0US251AAFB-PARKER-HYD-WHEEL-MOTOR-9-10672.axd

The pumps were something similar to this. Hydrogear makes a similar pump as well.
http://www.surpluscenter.com/Hydrau...WHITE-HYD-PISTON-PUMP-101010000012-9-8269.axd

It was a nice kit for the price. Too bad they don't have anymore.

Let me know if you have anymore questions.

 

[dozerbuilder01]

So that day finally came. I got to plow some snow. We got about 8" so far. Might get some more. It sure beat shoveling.

Another video with a bunch of random clips put together. They aren't the best.

Hopefully in a few years, my son can plow the whole neighborhood and make some money for college.

 

[Hephaestus29]

I watched the one of it going up & down the hill too. It looks like it makes pretty quick work of clearing the drive. You'll have it wore out before your son gets hold of it ! LOL

How much snow can you push before it starts spinning any idea ???

 

[jgreen-fsi]

I love it!

 

[daparrothead]

Wow this is so kewl! A project like this takes some serious skill's.

A+++ On this project Sir.

 

[Rodhotz]

Cool project, now to make it a little more real you need one of these!

This is the coolest build that i've seen on this or other sites, your doing a great job.

 

[CaseyJoes.]

This is my favorite thread on the whole forum! Personally the only thing that would make me enjoy this more would be if it was fitted with a Wisconsin THD engine. Very high quality inline 2 cylinder air cooled engine that makes gobs of torque, and would really look the part with the rest of the quality construction and style of your crawler!

Well, after the snow finally stopped, I got about 13" in my area. I plowed the driveway 3 times over the course of the snow fall but I never touched the back patio. So I had to go play in the deep stuff. I get hung up a few times as you'll see but I must be catching concrete or ice or something. Or I might have too much down pressure on the blade which is taking weight off the tracks. As soon as I bump the blade upward, I continue to push. For reference, the blade is about 15" tall and the top of the track is about 17".

I am having fun riding it but it will be even more fun when my son is old enough to ride it.

Very cool! I noticed in the video @ your parents when you dropped the blade it would raise the front end of the dozer up some and you could see the front of your tracks in the air. Probably same thing was happening in the snow.

 

[Garage Coffee Roaster]

Are you going to add some more weight so the dozer does not slip as much? You have plenty of torque.

Hehe... want to get into some serious trouble you could add a ripper blade onto the back! LOL...

 

[NASTYZEN]

That thing works great! It turned out awesome. You look like your having way to much fun.
So whens the next snow fall?

 

[signcrafter]

Absolutely amazing!

I've been reading this since the beginning and it's great to see it come together. Watching your video with the swing set in your back yard my first thought was as soon as your son gets on that thing he will plow that over!

Time to start making attachments for it. Put a 3 point on the back and make a drag box. A rototiller. Some different blades on the front for different things. The possibilities are endless! I would be making all sorts of stuff just for an excuse to get on that thing! A ditch witch attachment. Want to get fancy make a back hoe attachment for the back of it! Son could dig holes like crazy.

 

[pmason0]

Very cool, but you did say this was for your son right

 

[woody 73]

Fantastic Job Your son is going to love that; one day in the future he can say my dad made it happen in his Garage.
