Dynamark Mud/trail mower

I am still getting used to posting. So forgive me if this is a wired post, but
Red have you or do you plan on doing any engine mods for more power?

Looking good man, keep it up

Looks as though you might just have it ready for an Ohio mower off on the 20th of March... Hint hint

Let's try this for a third time because apparently on mobile if you swipe over it deletes your response and you have to start over.
I finally got some work done on her I got her running after some stupid wiring mistakes on my part(grounded out the kill wire before the ignition switch) I got my mud flaps on, my foot rest pads, a new support for the rear rack, a choke cable, foot throttle and a hand brake, she just needs a battery the shifter plate cut out, and some skid plate action and maybe some lights and she's done! I'm gonna post this then upload pictures

And I must keep up with my own posts Mathew d I usually get emails when someone replies to my post but I haven't lately and Bigmoot I don't have and plans of power mods for this one these twins have enough torque for now

Looks almost ready for renegade ridge

Well looks like shes ready for what, another 8 years of abuse?

Looks great man, you just hook the factory brakes back up? and you definetly need to make it to renegade ridge

redline itll be 10 years this november since i got this mower! hopefully i can get that many more out of it but with this twin..... idk lol i already rolled it once

creepycrawler and offroad ohio i hope i can make it but i came home with a three wheeler this weekend instead of bringing the dynamark back home, i bent the clutch down alot. the front end will come up off the ground just by giving it throttle idk if this is a mower i wanna bring where there is hills

Just load the front tires with a few gallons of windshield washer fluid, that will keep the frontend down, that's what offroadohio did till he got used to his clutch

I've done the same thing on mine. Need to reload my murray because it got a leak and I knocked the bead off and dumped all the fluid then yesterday my friend flipped it over backwards.

is there a mobile app?

Wow has this build come along way and so have I since I last posted. Since I last left this build off I freshly redid my old reliable the “mud dynamark” this was my 12th birthday present she was mint condition when I got her! 13 years later and boy has she changed. Every build slowly progresses through out the years and so do we. At the time of my last posting this was a bog tractor. There is nothing but flat muddy trails where I have most access to so that’s all I ever needed it for, and then the haspin rally came into my life, and then riding and becoming part of the Ohio Offroad mowers, and most recently the Top Tractor Challenge 2019. This mud mower named the “mud dynamark” has slowly turned into a killer trail machine!


Here is a list of modifications that have been made since last post I will try my best to cover them all, along with pictures
-mistakenly painted it light blue the day before TTC19
-18x7-8 sun f front tires
-24x11-10 swamp witch rear tires (amazing performance)
-custom rock ringed wheels
-home made dual muffler exhaust (sounds decent)
-removed my side mount brake handle(running no brakes at the moment)
- 2”x3”x3/16” rectangular tube custom front axle 2” wider, new reinforced spindles, all grease able joints
-front axle moved forward infront of original frame plate(2”-3” stretch)
-removed the rear rack and mud flap fenders and replaced them with a pair of oem style fenders
-just installed a pair tree kickers
-working on installing a new rack

Pictures to follow in next post

Haspin acres right after redoing it, haspin acres the next year





Post ride at my first taste of the trails at creepycrawler’s house, 10” polaris scrambler wheels with 3/16” rock rings I made, all new tires on the new wheel set up





The night before TTC 2019, during, and after taking home 2nd place!

New front axle build, after the front axle was complete, and the internal rubber bumpers to help the front axle from crashing into the frame during flex





Ride #2 at creepy crawlers!, oem fenders are back on!, and post roll over picture!






Some trail riding, rear rack mock up, and TREE KICKERS! hopefully no more pinched legs!

This old girl is gonna need another refresh soon, she gets rode hard and put away wet a lot! Seems like she always wants to be on top of me all the time, and if not me she loves being on top other people too :/. The frame is starting to show its age and has cracks and crack repairs, the motor is tired, the peerless 820 has been on its last leg for atleast two years now. It’s still sporting the haspin welded diff repair from 2018 I believe lol thanks moose and Doug! Lack of working brakes, clutch is getting worn out, and she’s slow. Did I mention the UGLY blue paint?

Here are the goals for 2020
-new motor, I have a 20hp vanguard vtwin that’s been in the shed waiting on a new build but I have picked up a new motor so this 20hp can find its way into her
-put a fresh 820 in it. Lock it with a solid go kart axle along with a speed gearset from Roms peerless. The mid range ratio
-I need hydraulic brakes of some sort, I’ll figure it out
-I need to figure out how to do a dual throttle set up on the vanguard. I want the governor to still work at lower rpm but I also want to be able to rev up past 3600rpms

Lastly I need to decide if I want to keep repairing this chassis or i should build a new reinforced chassis pan and just swap everything onto it

In the long run, I think you would be happiest building a new reinforced chassis pan.  If you were a casual rider like me, I'd say repair.  You are not, you ride regularly.  I've seen how you ride.  You like to give it your all.  Build a new frame man!  Like you said, this is your old reliable, and it has sentimental value.  Give it the refresh you would like and want to give it.  Don't hold back man!

@MightyRaze thanks mighty I appreciate the input. There is some sentimental value as to wanting to keep the chassis and just repair it, at that point there’s not much left of the original machine. I have a couple chassis kicking around what I’ll probably end up doing is reinforcing a new chassis pan and then put it way until this frame gets too bad

Can you repair and reinforce the original?

@MightyRaze yes I could but then that’s more down time, it’s bent up and cruddy. I could do a new chassis pan and swap everything over onto it in a day or two vs having to blow the whole thing apart, reinforce, then reinstall everything

I understand man!  

Have you decided on the new paint?  I know you like to dis on the blue!

Think I might go back to the maroon before the blue or another variant of a dark red. I dig the blue just not on this build, probably gloss black wheels or silver

I think that would be the best option. Less work on you and it'll be around for another 10 years. One other thing I really dig the blue but I don't think it's for that machine. A fresh coat of the old paint you had on it would be the best option in my opinion.

She really has come a long way! Definitely looks awesome with the bigger tires all around.

Do you have any more pictures of the custom front axle build? Sounds like a beefy setup. I love the bump stops too!

@AllisKidD21 I actually deleted all the pictures the other day, luckily I was able to recover them




Some of the frame repairs and re repairs

Now a bunch of photos of the front axle build













I forgot to mention I now have a 2500lb super atv winch on the front, I also intergraded front hood mounts into the front bumper supports to finally have a solid hood mount

All frame work for the axle house was made out of 12/10 gauge steel so very stout and puts even more weight over the front for hill climbs. My front tires also have about 2 gallons each of rc antifreeze

Oh yeah I do remember that you did fix the frame.
