Hydrostatic drive on articulating loader

[robirot]

Yes, i don’t expect the final build to be under 10k$, but then i will have a machine that is made exactly for my needs and new.

From a purely economic point it can be discussed if it is the right way to go, but for a commercial machine i would propably just buy a new device. Finally after all i first will do the plans and zhe. decide, what route to go.

Then it propably will be a 4 hydraulic motors setup, getting the axles will be harder and expensive and also it saves the problems with the drive shaft at the articulating joint.

Get wheel motors with a tapered shaft and hubs. That's what I did when I started to rebuild my Woods ZTR. It was cheaper than a single Hydra-Trans. But as already mentioned, you'll need a divider and valves to control speed. On top of that you'll need a HUGE pump to supply the appetite of the motors. (10-15 GPM per motor is not uncommon depending on size.)

As a side note; I abandoned my Woods ZTR rebuild when I bought a new 60" Bad Boy Maverick. I may get back on it when I quit having to work on my tractors.

Yes GPM will be high, but if i build it, it will run on an Lada Niva engine (1774 cm3 58,5 kw) engine, pretty sure that will be enough power to supply the pumps

If you end up doing this project, please share the progress with us. I always enjoy watching these projects develop and seeing different techniques from what I'm used to.

$500 it went fast.

Why would you need a divider and valves to control speed?

If you use a variable volume pump that's designed for this, all you need is a way to control the directional control that's built into the pump.

I immediately thought of the Steiner 525 sitting out on my back 40 with it's axles and hydrostatic drive and articulating frame, right up till I saw the need for 3000 pounds of cargo.

So each side can work independently from the other. In case you want to turn or backup.

frame, right up till I saw the need for 3000 pounds of cargo.

yes needs to be able to carry a full ibc tote
