Thanks for the input from everyone. I think that I will ditch the hydraulic drive idea. I already have the gearbox and transfer case to suit the engine so I think I will go this route instead. I will put a build thread up once I get started with it. Thanks again

Thanks again, good info and I am starting to understand a bit better. Yes it is just like the Kranman machine I want to build but with all 6 wheels equal size. I could build it with differentials and this would be much more within my skill set as I have built several competition offroad trucks...

I am probably demonstrating my lack of knowledge on the subject ! I dont have any knowledge on how to split the flows and generally how to connect this system up, hence asking for advice. I dont even know how to work out how much torque is required to move the machine forward and backwards. It...

OK, but if you allow them to travel at different speeds, wont it loose traction when one wheel either lifts or has no grip ?

It will be pivot steer. I dont want different wheel speeds, I want to have them as if the diffs were locked all the time. It will only be used offroad in the forest. I was assuming that I was going to have multiple pumps so this is no problem. The engine I have already has a power steering pump...

Thanks for the answer. It will be around 1200kg empty and around 5000kg fully loaded. Tyres will be 780mm rolling circumference. I would take all guidance with the pump, I havent bought anything yet. I was reading last night and it seems that you can plumb the motors through a series of diverter...

I am going to build myself a timber forwarder with crane. It is going to be 6 wheel drive and I would like it hydraulically driven. I am thinking of using these for wheel motors : Silnik hydrauliczny BMR chłonność: 200cm3/obr obroty: 300obr/min z łożyskowaniem do rębaka I am after some advice...

Hello again, I now have 2 options from different suppliers. The first is the parker motors above, they look totally perfect, but the price is a little crazy. The other option is to use standard wheel motors and use a valve like this one ...

Thanks for all the info. I wanted to try and avoid the arms which disconnect the drive if possible. This looks like the perfect solution, but I havent found a price yet : https://hydraulicsonline.com/product/parker-tf-series-medium-duty-clutch-motor/ I need to work out sizing, etc.. yet. It...

Thanks for your replies, its good information. They say every day is a school day, well this is my first day at school ! I would be planning on using one of these motors ...

Hello, I am wondering if you can help. I am building a forestry trailer and I want to have driven wheels to help in the bad ground. I have been told by a couple of people that if I use wheel motors with a valve block which has a freefloat position, then there will be very little drag when in...

I am about to start planning a timber crane which can double up as a light duty backhoe. I am wondering if anyone has ever tried to use the ring gear/flywheel off a large truck to do the slewing/turning. I was thinking to drive it with a slow hydraulic motor and use the gear from the starter...

Hello there I want to make myself a micro tracked timber skidder from scratch. I am totally happy with the mechanical part of the build, but hydraulics are a new area to me. Details of the build are as follows : 10hp Chinese diesel engine driving the pump Main drive wheel on the tracks 24"...
