[Complete] Redzz02's Haspin Build [2018 Build-Off Entry]

Looks great! The blower shroud sure stands out, haha. I just noticed on your 3-link that the upper link is pretty much the same length as the lowers. I don't think you'll have any binding problems though since it's mounted up a bit higher on the frame crossmember than the outer links. Plus I guess you don't have like wicked up and down travel or anything, haha.

....so did the 4x4 get scrapped or just a different engine put on it?

I really like that steering shaft support idea. Seems like it would hold up for a really long time. But why mount the engine like that? Does that really save you any room?

@AllisKidD21 in my pt. 2 build video I over flex the suspension way past my shock limits, and 0 binding

@CraftsmanQuad19 first off ultimately from what I've been told the 4x4 rests in the scrap yard. I traded it as a rolling chassis for a trike, he then traded it. That guy ruined it and told me he sold it to a scrap guy for 100$ ;(.

Secondly yes I needed to mount the motor in reverse. One reason is I needed to keep the weight towards the front end on the mower. And two if I was to mount it forward, my front axle would have to move forward( mowers with stretched front ends make me sick) and my shocks would have to come out from under nieth the hood and so would my supports.

I'm not a big fan of hob cobbled builds, I like them to be as clean looking as possible and mounting the engine backwards was the ideal way to achevie that for me

Yeah that's why I was saying, it should work fine because the center link is a bit higher up on the frame mounting crossmember. That sucks about the 4x4 tractor. Shame to hear that a cool build like that is just going to waste.

@AllisKidD21 it's all good I just wish I would have saved the axles too and just scrapped the frame, I still have the hood so my next 4x4 build will have the original hood on her

Oh nice! Those squarish Dynamark hoods and grilles are super neat looking in my opinion.

@AllisKidD21 if you couldn't tell they are my favorite haha

Yeah, hahaha. Don't seem to see too many of them in the off-road lawn tractor world though really.

Could you snag the axles back from it? Maybe buy it back in as parts? Shame to see everything from that build go to waste

Rust in Peace 4x4.  Sorry to see a tractor go like that.



Anyway nice progress on this Dynamark.  I like how you re-purposed the wheel hubs for steering shaft supports.  That's a clever use of materials.

Is the motor cage going to be under the hood for added motor protection?  Is your stock hood going to fit over it and mount to it?

Are you going with direct steering?

@CraftsmanQuad19 I went to one yard and didn't see it, it's most definitely crushed and shredded by now this was over a year ago


@Crazy_Carl the hood will rest on the cage and ultimately I plan to solid mount the grill, and mount the hood itself to the cage and the dash with pins. Yes I am going direct steering, I prefer it with speed.

this thing is the tits man, cant wait to see it at haspin

spent about three days slowly figuring out this clutch, and this god awful cold weather doesnt help the brain at all either, but i think i have finally figured out a set up to work, im not so happy with my belt i ordered off ebay, it is a 5/8 belt but it is really thick so i might end up switching down to a half inch belt if i have issues (all my other builds run 1/2 inchers and ive never had issues)

the clutch pivot is running on bearings to keep it from flexing,

i got my brake caliper mounted

heres some pictures of the clutch, belt routing, brakes, and a teaser photo

Hardly a teaser...looks pretty explicit to me lol

I watched the video earlier today, this marchine is coming along great. Really looking forward to seeing it at haspin. Would love to see how it compares to the mowrons and mr.moo

That setup with the clutch bearings is a really good idea! With the amount they'll be turning they should last forever.

Really cool looking! This Frame you made is soo sturdy! Your clutch and suspension also looks great. WIsh my mower were built as good as you do yours

That is quite the setup! Very sturdy looking.

looks like 1st place to me...

Yeah, @redzzo2 works very hard

Nice progress!  I like the way the factory Dynamark body work looks on the custom chassis.  Looks like you've put a lot of thought into your clutch.  Although those look like shielded bearings you used in your pivot not sealed bearings so they might not like water very much.  Although it's not like they're turning at a high rpm like a clutch pulley.  Did you think about using an oillite bushing there with a grease fitting instead?  Also your brake caliper bracket there looks really well made.

@CraftsmanQuad19 just a tad explicit lol

@SebastianAlbrecht the hardest part is taking whats in your head, and making it come out in person. take your time its definitely do able!

@biggasmowers Thats the goal

@Crazy_Carl its what i had laying around, im not too worried about them, if they seize up they are very easily replaced and super cheap being skateboard wheel bearings

alot more has been accomplished along with some set backs. lets start off with the bad

1. my steering wheel from bmi karts is sub par, it has a slight bend and tear drop shape, ultimately it is more than usable just annoying. reason its an issue is bmi couldn't compensate me in anyway. turns out all of the ones they had on hand all had a slight bend and teardrop shape, so its a poor quality product.

2. i hate the way my exhaust has turned out, with attempting to keep exhaust off of everyone i pass, angling it downward too much has made it look odd. i will be re routing it and making a new different shaped plate for the side of the hood

3. my hydraulic brake set up was unsuccessful. it would build pressure randomly and wouldnt bleed so i got a new one, with  much smaller caliper but it still works, (good news) my original bracketry still works!  

4. i do not like the way my front stinger has turned out so it is most likely going to get cut back off

5. i went to clean the carb and the bowl seal was stretched and warped so i couldnt fire the motor up for a sound test on the exhaust

NOW onto the good stuff!

brake system set up

















patching the cut out spot on the one foot pan


exhaust setup (for now)


im not a fan of the shape of the plate or the pipe exiting the hood, this will be changed but may stay the same until after haspin


stinger that is most likely coming back off


start of the battery tray


cut out of the dash for an access panel


drilling holes for some switches up ontop and the sides for no reason haha


the start of wiring


rear bumper tacked up


new battery charging up


once my new seal comes in and some belts, ill be able to fire this thing up and see if it actually moves on its own. the front tires are mounted, hopefully this week i can weld up a fuel tank, and i still need to find a seat

I think that front stinger actually looks pretty good.  Are you thinking about going with something that matches the body lines of the hood more?

So did you get rid of your hydraulic caliper and used a mechanical one instead?  Were you using a previously enjoyed master cylinder?  My friends motor cycle had a very similar problem with his front brake master cylinder after the bike sat for 20 something years.  The front brake would lock up randomly.  I took several hard looks inside the master cylinder and it turned out that the tiny hole that is there so pressure can't build when there's nothing pushing on the piston was plugged solid.  After I cleaned that hole out it worked like brand new.

@Crazy_Carl it is still hydraulic, i just ordered a different one. it was a brand new kit but it was china and has been sitting since last fall. it had some clogged in the master that i cleared out, and it still periodically built pressure and then didnt, id bleed the master and it would start pumping then the banjo fitting wasnt sealed fully, it was more of a headache to get the original one going after an hour or so so i just ordered a new one. if the stinger grows on me ill leave it, but most likely just going to cut it off and leave the bottom tube

haspin is 4 days away and i think we are going to make it, it is mostly together now, but it is going to need alot more tweaks and a few tings redone before the end of the build off but here is some more pictures!







































redid my steering, depending how it performs ill put i gearbox or so in it, redid my brakes several times third fuel tank was the charm, still cant find my hoke flap for my carb its been stress full last months, but i can say it technically passes as complete via the rules, stay tuned for many pictures and videos during and after haspin next week!

Looking good! Frame looks good painted black. Hope you get it done in time for Haspin.
