My Senior design project - a "Swamp Thing" tracked vehicle clone

Instead of detuning the engine, it would be much simpler to restrict the movement of the accelerator or hand throttle.

Please explain what this is referring to?

So lately, I have been working trying to finish up the dashboard. Here's a snapshot of it powered up but without the engine running. Everything works! Next up, I plan to update the steering master cylinders by adding vacuum boosters.

I need to get a vinyl label made up for the transmission gear over-ride knob to replace that temporary paper label.

I got the vacuum boosters added onto the steering master cylinders. I helped a bit but still turns hard on grass as expected. It should work great in the snow. Lately, I've been tinkering with a snowblower design for Snowzer that will use a underutilized 20hp Onan I have sitting in the shed. I am not sure I am going to build it - we'll see. Does anyone have any old scrap snowblower augers they would like to donate for a good cause? I'd need a cast iron right angle drive too.

How wide an retired snow auger/blower are you looking for?? I assume it would be off a compact tractor.

 

[Garauld]

I was going to collect some augers off old Troy Built or MTD snowblowers and cut/weld them together as needed. I am designing the snowblower for Snowzer to be 62" wide.

Any updates Gary?

Not really Arly. I've been playing around a bit on the design of Snowzerblower which I may or may not build:

Here's a design question for the group: when you look at the 5v belt being driven by the 20hp Onan engine, you'll see a belt tensioner device. This will act as a clutch to engage/disengage the blower by tightening/loosening the belt tension. I would plan to activate it with a small pneumatic cyclinder (under the housing) using a three-way solenoid valve inside the cab piped to an air supply. Do you think it work better as shown to push on the belt or should I move it to the inside of the belt to pull on it to tighten the belt? Stay well.

Good! Now I got something to think about.
