New FREE Dynamark!!

What should I do with this dynamark? My friend down the road is an old man and just gave me this lawnmower for free. As long as I picked it up..

It has
11hp briggs motor
Hi Lo 3 sp.

Oh and CHMN now I got a free lawnmower.. lol
I still wish it was a stx38 lol

looks like you could turn it in to a racer mower pretty easy. but i guess i got lucky when i got my stx38 for free

Racer... Humm never really built one before. I am thinking..
1 take rear end out and dip it in oil and grease it all up.
2 take a 2 inch pulley and mount it in the rear.
3 new belt.
Anything else?

maybe change the front pulley and lower it a bit if you can. i think most people that have a racer mowers usually put some type of gas pedal or a hand throttle on the steering wheel

it has got a 3sp Hi Low rear end. Anyone know if this is the peerless 600?

Dynamarks dont have that great of steering to begin with- id use a direct steer setup - youll need it when you lower it.

Any smaller then 3" on the trans - the belt will fall off- 2" is too small. I know on my dynamarks they all run oil filled transmissions - id use a heavy gear oil - i threw lucas oil additive into my murray's trans - thick stuff but sticks to everything. Id also be looking into better brakes.


I like my foot throttle on my MTD more then the hand one on my murray - easier to control - all you basically need is a return spring hooked to the throttle ( to snap it shut) and a bicycle brake/shift cable to a pedal /hand throttle- i used small u clamps looped back to the main throttle cable .



In the picture i had to temporarily use some bolts i drilled out for a cable clamp- it has the u clamps now.

Yea I am not looking to race it. Just something to play around with..

gonna wanna weld front axle stiff... if not it will want to flip in every turn. wut size front pulley? and iv heard anything below a 3 inch in the back it will start to slip alot

wish mine was that low stock.. it would have saved me alot of work

Yea I just want something to go faster. Not looking to get in to crazy racing. Maybe a 3.5 inch pulley.

Mine arent for racing either - but like what happened to my murray - once i had a taste of some speed, y want to go faster.

I havent really been out for sub sonic speed- heck the 30 plus seemed fast enough at times, but im aiming for around 50 mph. Was just the tractor weaved all over ( front axle wasnt locked, stock steering) .

With the mod MTD- handling is TONS better - feels stable , steers tight ( even with stock steering) , did some basic lowering ( i have more planned soon) - im considering using a go kart clutch , and a straight axle - IF i can build that right angle gear box correctly- with the 18HP twin, it should move pretty quickly.

I still want to tinker some with my old murray sometime- see if i can lower it a bit, lock the front axle.

I just got a stage 2 snowblower for it for 50$.. lol I dont think I am going to race it. I will probably do some more repairs and sell it with the blower for a little profit and buy another offroad project..

Hi Lo 3 sp.

Free is good, your next step is to get paid to take them away. It looks like my Dynamark that I'm building. I just love the looks of these machines, they have one of those aggressive stances.

Get PAID to take it away? Omg you must be the luckiest guy alive...

If you guys were closer gheesh. I have nobody to offroad with . My buddy expects me to build him an offroader. I was like nooooooo My blood sweat and money. You need to help out a little if you want to play.. lol

same here i only have one friend into this kind of stuff and he always wants to use one of mine because i spend money on them and actually take care of them. his are all stock so they cant go anywhere so half the time i dont even unhook the tow rope because its not worth my time when i will have to hook up again in 2 minutes

I just plan to hang with friends who own atvs. If I can't make it, they can pull me out.

i still need to make my tractors so they can go offroading but i think i need to get one of my friends to get a lawn mower so i have someone that i can drive with so if i get stuck i have someone to pull me out.

LOL, I got paid $40 to haul the John Deer in my avatar away. Its amazing what people throw away and what they will pay to get rid of them.

I had a pull off today. My dynamark with a 11hp engine vs a craftsman with a 4sp 12hp engine with deck. I lost on asphalt.. but it was equal in snow..

If your gonna make it faster, upgrade the brakes. Stockers wont help much if you break an axle.

OMG that is so sweet man! i restore it/ mild mod it.
great score man!
