I was informed I could go ahead with a project thread on my tractor, so here goes. Maybe it will even motivate me to get this thing done.

First, I have to start from scratch. My lady didn't like the fact that I had three unused lawn tractors in the yard, so they are gone. I told her I could work on our current grass beheader, but she isn't crazy about me removing the deck, so that's a no-go as well. Anyway, I got to find me an old lawn mower.

The first thing I'm probably gonna have to do is engine work, but that'll come when I get my hands on one, so I ain't gonna go into details yet. Past thoughts included me placing a 4-wheeler or small motorcycle engine on it, but I don't know about that either.

Since this is going to be a completely custom build, I'm gonna have to piece together a 3-point hitch system. On my old version, it was just a matter of cutting and shaping scrap iron pieces (I worked at a hardware store, so this was candy :smile1:). That's probably the same approach I'll have with the new project.

Powering the system, though, is gonna be a little different. The old version had a hydraulic pump hooked up to the motor, which operated the lift. I can still go this route if I need to, but I was hoping for alternatives. Manual lift comes to mind, but some of the attachments may be too heavy. Has anyone used a pneumatic system for something like this? If it is possible, I could probably do something along those lines.

One thing I'd like to add that my old one didn't have is a PTO. If I'm gonna have a tractor, I might as well have a tractor, right? The problem is, I don't even know how to begin with this. I've thought about a belt driven system, and a standard gear system, but I just don't know. Any advise on this would be appreciated. Pics are nice too.

Anyway, that's it in a nutshell. I hope to get this thing going either this week or next and I can update this thread as I go.

Just a couple of quick thoughts on your planned build Hubb. Since you say you want a 3 point hitch I think you are talking garden tractor sized project. Do you want it to be able to handle a full line of attachments such as a plow, disk, mower, snowblower etc. When you say PTO do you want just a belt drive or are you talking a shaft drive setup? I would consider using hydraulics for the lift over a pneumatic lift. You have more control with hydraulics and the cylinders can be a lot smaller in diameter with hydraulics, more pressure with hydraulics than air system. If you are thinking at all about putting a loader on your tractor the hydraulics would be handy. The other option would be to use electric actuators for the three point hitch and loader. Just a few of my thoughts, Mike

I would definitely not use pneumatics for the lift. If something hung up while lifting, then let go, the compressed air would shoot the lift up like a bullet. With hydraulics, if hung up, the bypass in the pump would kick in. You can get some wild action from pneumatic.

Why don't you sketch it out, make a build sheet, run it by the guys here? When you get a finished mock up that will fly, then start building. You don't want to have to try and add wings after youv'e jumped from the cliff. In your post I here a lot of wishes, and dreams, but you need to have a true vision. What's your background, your ability, your talents?

I do a lot of DIY projects and I've learned a long time ago to make plans before the build. The other tractor I had (me and my cousin built when we were about 14) was pieced together without plans, but it worked. With that said, I've been doing stuff like this for a while now. Cutting / welding / shaping metal, small engine work, etc is all under my belt. Really, it's just a matter of doing it.

I'm working on the sketches now. As soon as I am able, I will put them here so they can be criticized / improved on.

Yes.

When you say PTO do you want just a belt drive or are you talking a shaft drive setup?

Yes.:smile1: I'd like to be able to hook up the deck to the 3-point hitch to still be able to cut grass. And, to be honest, it would really just be for bragging rights. But since I really have no experience fabricating either system, I don't really know the route I would need to take. I would think that a belt driven system would be easier, though.

I am anxiously anticipating to see this progress. :D

I vote go hydro for the attachment lift system at least.

As George said if you could find a good hydro tranny with a ported charge pump you would have enough hydraulic supply for a lift cylinder or two for your mower lift and a three point hitch. Not all hydro trannies have the ported charge pump. If you get a hydro tranny from a garden tractor and the tractor had hydraulics on it most likley it has the ported charge pump. If you wanted more hydraulics you could add another pump later
