Put PT422 on Side (Kinda)

[J_J]

Another fear story. About 5 years ago, I was cutting a slope with a Dixie Chopper 60 in, with no ROPS, that I had been cutting for three years. This one day, the grass was wet and I made a down hill turn, which I hardly ever do. Started to slide down the slope in full reverse, no good. There was a 4 ft drop off to the next level down. As soon as the front wheels hit the edge, I bailed out, all 210 lbs of me bit the dust, and then the Dixie Chopper fell on top of me. Engine still running upside down. Was afraid gas was going to spill on me and I was pinned under the Chopper. I managed to cut the engine off, and drag myself from under the Chopper. I had just missed an air condition unit when I dove off, lucky me. If I had stayed in the seat, I would have landed on my head with the full weight of the machine. Anyway I hurt all over, and thought my leg was broke. They determined that I had split the side leg muscle, and that I might just live with it that way. ROPS might would have helped some, but there is nothing to hold the head close against the ROPS. Also, the steering handles can't open up unless you are in neutral. Extreme fear factor set in. After that I cut that slope with a walk behind mower. I never wear a seatbelt around water..

What do the regular wheel motors cost??? I Thought someone commented on another post that a new plain motor was about $400

How about a scrub brake like minibikes used to have? (A curved shoe that can be moved into contact with the tire tread.) It seems like it might even be pretty straightforward to design it to be spring-applied and hydraulically released (using small, cheap cylinders from Surplus Center), so it would automatically apply in case of hydraulic failure. It probably wouldn't be hard to design it with an easy way to release it (or just unbolt it) for towing.

What so you guys think of a wood or rubber wedge with a chain on the end. In an emergency, drop the wedge in between the tire and frame, and the tire will grab the wedge and jam it tight. The chain will stop the wedge at the right place.

This is a picture of my hammer holder, and you can also see the spray lube holder behind it. You may wonder why a hammer . I have the 3 pin hook up for my attachments. Some times those pins need a little extra help to remove them.

That is kinda what I had in mind only make it completly a mechanical brake without any hydraulics for the two front wheels. When I mentioned Fred flintstones brakes I had got my pt on a hill where it would coast down and I put both feet on the two front wheels to see if I could stop the machine from leaking down the hill. I couldn't completly stop it but I could slow it down quite a bit so I thought that with a scrub brake with mechanical linkage and a lever to apply the brake with your hand and the handle being longer from the pivot to the handlethan from the pivot to the brake pad [shoe] , that would give you more leverage. I beleive this would work at least for the green machines. Put a spring on the brake shoe where it connects to the linkage to let it have some give that way you could fix a notch in the handle so that you could fix a hinged peice of metal that would fall down on the handle and catch in the notch if you wanted the brake to set and hold without you having to hold the handle all the time. It would be a help when using the minihoe while on a hill, or any other job where you wanted the machine held in a stationary position. I'm glad someone else has the same idea. Now who's got the tuit to duit.

JJ,

I'm not sure you could rely on a wedge on a chain to drop in place securely enough. I think I'd want some kind of guide to make sure it didn't get spit out, and a way to force it into place.

A simpler alternative to hydraulics and automatic application might be spring loading and a locking pin to hold it open. Yank the pin (maybe with a cable attached to a "panic handle") and the wedges or shoes jam the tires.

Let's keep the ideas coming. Maybe we'll come up with something simple enough to actually build!

First the question would be, is this something you would like to use for just emergency stopping? Which is my interest, and more like what J.J. is describing, or something two fold for emergency braking, and also when using attachments like the mini hoe. /forums/images/graemlins/ooo.gif

Toy,

That sounds like it should work as a service brake. It might be a challenge to rig a linkage that would be quick and easy to grab for emergencies, but I think that any additional braking would be an improvement.

Hey, I just had a thought - it might be possible to use something like a mechanical clutch pedal linkage on an old truck or ag tractor. Put the pedal at the back of the footwell so you could stomp it with your heel. I'll have to look and see whether there is room for a pivot tube across the tub either inside or outside of the front wall. Hmmm....

The wedge idea is a good one, that can be expanded on for simple emergency stopping. Much less time consuming, and easy to make. Just my 2 cents. /forums/images/graemlins/smirk.gif
