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.

Some more stumpin'

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)

Really nice BFreaky.

 

[BFreaky]

Thanks. It works as expected. There is always some space for minor improvements, but I'm satisfied with it as it is.

 

[BFreaky]

And finally the last one, probably the biggest...took me half hour and another 15 min to dig a hole big enough to bury it at reasonable depth. The machine passed stress test, if this job didn't break it, nothing will. So now we have some 120 m2 of new clean land.

It looks like nice soil. Will you plant something?

 

[BFreaky]

It's my brothers land, he plans to grow potatoes here because they like this kind of soil

 

[Kyle_in_Tex]

I love potatoes! Prepared just about any way. 120 sq meters can grow a lot.

0.03 acres, it would be a big garden patch.

Have to to laugh at 0.03-acres being a big garden patch. Grew up on a self sufficient farm outside of Boise. Dad used his GI Bill farm purchase to buy an orchard outside Boise, then built a new farm house, and after the five year limit, subdivided it and paid off the loans. We had a full acre of garden to fill two chest freezers. Every fall, mom would blanch and freeze enough vegetables to fill one freezer, the other one held the meat from a grass fed steer, and a couple of deer.

The grandparents had about an acre and a half in garden. Their ranch was off grid, and grandma, canned every day for a month every fall.

looks like that much more than what they had
1 meter wide x 394 feet long. That would grow a lot of potatoes for a privateer.

This is not a garden, it's a farm land of 3 acres all together but this last purchased part had some trees and bush on its edge so we just cleared it because there is no point of keeping it.
