my homebuilt tractor

[Iplayfarmer]

I was perusing YouTube (as I sometimes do) and came accross this video about a homebuilt articulated tractor similar to what you're proposing. I know a lot of your plan is done, but you may be able to poach a few ideas from this guy. His tractor seems very well built and very well designed.

This is a very interesting project. I am wondering, will it be a 2wd or 4wd?

I'm pretty sure it's going to be 2wd. If you look closely at the pic showing the articulating joint, there is no provision for running a drive shaft though it. That's how every articulated 4wd tractor I've ever seen was designed. I suppose that a clever person could manage to drive the front wheels with an entirely separate means such as another gas motor up front, or maybe a hydraulic motor. But, in the case of this homebuild, I don't think that's part of the plan.

Hey Kebo... The whole PT line is 4 wheel with 4 individual hydraulic motors.. so, there are articulated with 4 wheel drive.

it will have another hydraulic motor in the front but i have to get it first also will air in the oil matter or do i need to replace it

IMHO, Air in the oil is not a deal killer. Let it settle and the air should come out.

The other sourse of foamy oil, water, is not good. If you ever get foamy oil due to water, toss it and start over.

(I reserve the right to be wrong should someone more knowledgable or just more convincing chime it to the contrary.)

well i am going to get a new engine and pump here is what i want a 16 hp diesel driving an 8 gpm pump at 2500 psi but what i want to know is 8 gpm enough flow to drive 2 hydraulic motors and 4 hydraulic rams

thanks andre

hi guys well i bough a 10 gpm pump and a 16 hp chonda engine i jave 2 weeks holidays and i hope to get the tractor running finally.I also want to start on the fel i was wondering whether it would work if instead of two loader arms i only have one in the middle as i don't have enough box tube to build a twin loader arm but i do have a long piece of small I beam that i could mount in the middle and use two lift rams and one dump ram would this work. i would be like this cad plans loader but with two lift rams. thanks Andre

Check out this thread on one arm loaders. There are some pics. http://www.tractorbynet.com/forums/grey-market-tractors/128886-unique-gray-market-front-end.html

Over the weekend i started her up with the new pump and engine and low and behold it worked. Although it didn't steer i later found that the valve i used for steering didn't work so i connected the steering ram to my drive valve (two spool) it it worked although a little fast. Then the drive motor slipped on the drive coupling that was fixed by filing a key way in it.Then when i when to test it again it just wouldn't work i opened the tank and the oil was just froth so i am going to add a tube to the bottom of the tank and more oil. thanks guy pics up soon.

These pictures are smaller and hard to see any details. When you get the bugs ironed out I would like to know what kind of speed you get. Thanks

well im still putting away on the loader it runs and rives now. i built a loader for her but i dont like it so im scrapping it and either building a new fel or putting on a 3 point hitch.

just a thought, but my Wallenstein log splitter uses automatic tranny fluid in the hydraulics. Standard pump, valve and filter, but a tank full of ATF. Wallenstein claims that the transmission fluid doesn't foam. And so far we've never had a problem with foamy oil in it.

 

[David Devuono]

Bobcat did you ever get you foaming oil problem sorted out. Can you comment on what kind of speed you are getting. I am close to getting my own buggy going but am interested to know more about how things are working out. I have not seen any pictures of how the hydraulic motor is connected to the rear end. Wheres that video you promised?

i did sort of the oil i cleaned all the hoses and resealed the tank stopped the oil contamination. it top speed is about 10 kph. i dont have any news at the moment as it am re building it. as it is just to dam wide i really should have done that when i started but i was only 14 and didnt know to much about that stuff know i have the experience i will narrow the axles and rebuild it.

 

[bobcat fan]

hi guys a bit of an update i decided that the tractor was to big for my need so tractor mk 5 has begun i am making a single tube frame like a cadtrac and am narrowing the axles down the frame is made from 4x4x1/4 tubing. i have already finished the articulation joint and one i figure out how to shorten axles i will transfer all the components over with out the need to drain the tank of oil. photos coming next week

 

[kebo]

Sounds like evolution in action lol!! It will be interesting to see the pic's of your newest design.
