hydraulic scheme

[Isthola]

Hi, I'm new here. For our zB1-15 Bulltra I'm searching for some advice installing a rear shovel.
Does anybody own a hydraulic scheme of this tractor? As far as I understand the hydraulic system on my tractor, back and front hydraulic are in a single system. Lifting motion means light weight first lifts then the heavier weight. Lowering means heavier weight first, then light weight.
Does anybody know whether it's possible installing an second circle?
Thankful for any advice.

It's likely that you can tap the hydraulics, as with most tractors, however whilst I hope someone here can direct you, there aren't many of these about in the US so info is limited. Best I can do is a Japanese user manual with a wiring diagram! If you take some pictures of any valve blocks on your tractor it may help others help you.

Welcome to OTT
Although I'm not familiar with your tractor model most hyd systems are very similar. You can probably add a control valve by inserting it so hyd oil flows through the valve in route from pump to 3 pt hitch.

Post some pictures of the hydraulic piping and we should be able to tell you where to tap into the hydraulic system.
No you don't need to add in a second loop, the main hydraulics should be good enough to run what you need to.

Thank you for this quick reply.
This manual is very helpful despite it's japanese, but pictures show some details.
Next days I'll try to install the mechanical parts without hydaulics and than send pictures. I found some installations in this chat done in 2009, but I'll try an easier way.
As soon I have pictures I'll be back.

Hi, now I have some pictures of my planned installation and a hydraulic circuit scheme. This is a scheme of a B1700 hydraulic. Does anybody know weather it is similar to a B1-15? Or is anybody able to show how this single circuit could be completed with another double acting cylinder? My plan is to use rear hydraulic for lifting and lowering the shovel and the double acting cylinder for tilting.

Thank you for your information.
