Tractor backhoe - homemade

[BFreaky]

Made some upgrades; joysticks got direct link to distributors because cable control is waay to jumpy for this kind of machine. Also, hydraulic pumps are no longer mounted directly to the PTO shaft, that made coupling a nightmare because both pumps and gearbox weigh 36 kg so I had to lie down and mount it overhead...that's why I changed pump rotation, bpught different type of gearbox and turned it 180 to get some distance to use short cardan shaft.

Also added block valves to secure outriggers

I found some free time and made a stump ripper, it makes a great job pulling tree stumps.

Nice, the tractor sounds like it's just barely above idle. Must be a beast.

Tractor works at 1200-1300 rpm, backhoe has tandem gear pump 2 x 50 cc/rev, pto works at max 540 rpm, here about 400 rpm. It can go even faster but what's the point, it will only heat oil faster

Some great engineering!

Have you used the triple boom adjustment already in a situation where you needed it ?

 

[BFreaky]

Yes, all the time. Triple boom is the best decision ever. You can extend it to reach far, and curl it to get as close as possible. Also if you lift something too heavy for your boom cy, 2nd cylinder will help

Close, max power

Digging a hole to put all those roots and stumps inside. I have to make a bigger bucket to dig it faster. This is only 400 mm wide(narrow)
