Dynamark Mud-Bogger (UPDATES)

New guy here! I've been followin' you guys as a guest for a while and figured I'd post my tractor for you guys to see. I'm kinda at a stand still right now and need some ideas. Anyways here it is after my latest creek ride..






Here's a tool box i made.


And heres the rack i have mounted on the back. I'm gonna weld some pieces around it to give it some sides.


This beast had been sittin in my barn for around ten years before i pulled it out. My papaw had bought it new in 1980 something.
What i've done so far..

-Took the deck off
-Put Atv tires on the back
-Strengthened the hood and some of the frame
-Took off the decals
-Spray painted it
-Trimmed my fenders off to fit the larger tires
-Made and mounted the toolbox and rack
-Adjusted the brake/clutch to handle more speed

What I plan on doing..

-Adding new tires on the front (need ideas)
-Modifying the rack more
-Repainting (maybe)
-Playing around with the pulleys and brakes some more to make for a smoother ride
-Hopefully find a better steering system

Thanks for lookin'. All ideas and comments are appreciated!!

what size tire in the back

You know i really don't know off the top of my head. I'll have to get back to you on that.

front bumper and maby put the old rear tires on the front check out my builds for some idias

I have a stock version of one of those - when i bot it many years ago and replaced the shattered spindle bushings so it would steer straight - and while i rebuilt the deck i took it down in the swamp behind my folks place - it dug in pretty good in stock form, only thing i changed while i mudded it was the smooth front tires - thing wouldnt steer worth a darn. It actually still steers pretty bad - even after adjusting and tweeking the steering setup.


Since it sounds like itll be doing permenent mud detail - id go for a pair of ATV or knobby wheels for the front - best steering would be direct steer , unless you plan on lifting it , in that case retrofitting another steering setup off another tractor might be better.


The transmission in mine is pretty beefy - its already set up stock to run gear oil .

I bot a pair of rear tires similar to yours at a flea market for $25 - wooley boogers - those are going on my 90's GT murray trail machine ( eventually) .

I find the best places to look for stuff is at flea markets/thrift stores - our local 'Restore' also has a bunch of cool stuff now and then - bot a bunch of golf kart rims real cheep ( last 2 were $2.50 each) - so those are places to look.

I agree about the tires. I can barely even steer in the mud haha. I'm currently looking for some tall knobby tires for the front since the back tires won't fit with the foot boards. I doubt i'm gonna change the steering too much though. I might just beef it up a little bit.

They're 22x11x8. Pretty great mud tires if you ask me, haha.

alright since u have 22s in the back i would put 18s in the front or 16s

So, today has been crazy haha
My cousin bought a 12 hp Murray to make into a mudder, and asked me to help him.





After putting fresh gas, and a battery in it, it fired right up. After we took the deck off and inspected everything, we changed the oil and the drive belt. Afterwards he drove it and i drove my Dynamark around the field and somehow both of our tractors gave out at around the same time. After two long pushes to the garage i fixed his mower. He couldn't get his to start, which was caused by a faulty solenoid, which we replaced. Now here comes the question..My tractor feels like it doesn't have enough power to even move. It jumps and jerks and will move a little in first and reverse, but won't move up and kind of hill. I noticed the belt has a small worn spot on the fat side. It almost feels like the belt is slipping. Any ideas?

Time for a new belt - get a kevlar red/green/blue belt - something heavy duty- wont be cheep, but itll last longer.

Actually, i was suprised to find that the pulley thats attached to the brakes was spinning too close to the brake pedal housing and was rubbing. All i had to do was re-adjust it so it would be a little farther away which also tightened the belt too.

I added a stack to my mower and i love the sound of it! I made it out of some old pipe. The only thing i had to buy were the elbows.

how do you upload photos i try and it will not upload?!
