Dynamark offroad mower

This is my dynamark that I pulled from a shed after 20 years. I built it with 27 inch rear tires. This is the 1st tractor i ever built. Unfortunately the 930 transaxle broke yesterday so a build is to come in the spring


I plan on replacing the 12hp Briggs with a 20hp opposed twin and adding different wheels and tires and possibly an 820.

Cool mower dude I like the low and wide stance! Ouch... that hurts, get er fixed so we can see more! Lol

The wide stance mowers seem to always snap the axles, too much stress I guess

The Wheels may come back on a future project but I am unsure at this point

You could probably make a brace to hold the bottom bolts of the transmission. That way even with the wider tires it wouldn't spread out like that and crack the case.

i gotta get me a dynamark someday

The makers don’t plan for our rough treatment, but WE can plan for it.

A gusset and plate outside the frame could pick up all 4 bolts out there and probably prevent such mayhem. A lower cross brace could be added too.

I’ve always been of the mindset that the best way to do a setup like this is a doc locker/live axle and to put some bearings and build an axle housing out of steel tube. I don’t know if I explained that good but I hope it helps. Might be Monopoly money but it’s my 2c

Thanks guys for all the feedback!!! Does anybody know if an 820 will fit in a dynamark 12/39

Yeah, @redzz02 has one in his I believe.  The mud dynamark build somewhere.

A very nice model, I haven't seen such on sale for a long time. I like that you repair it yourself; rarely will anyone undertake the repair of such equipment. I usually don't mess with this and just pay specialists to fix this piece of equipment for me. I recently ordered equipment for the farm, and I hope that I will not encounter any breakage soon since I paid enough money to not know the problems. I would also like to know who of you also ordered something there and whether everything is fine with your equipment after some time

An Update of sorts, I Guess, So the dynamark has not been worked on and will be getting some upgrades soon. All I have done is move it to the barn so its not taking up any valuable room for my truck project. So Upgrades SOON!
