2003 TLB L35 BT900 Backhoe Hydraulic Thumb

[RaleighL35]

I wanted to share my latest project on the L35. I could not find anywhere on the internet where someone else has attempted this type of thumb installation. Long story short, I Frankensteined a way to add a hydraulic thumb that is as close to a factory option as possible when it was never offered by Kubota for the BT900. I did not like the idea of an aftermarket spool valve with hoses hanging all over the place.

I was able to find a Husco sectional valve 5002-A1 on Ebay to add to the controls. I noticed all the holes were already made for the section to be added. ($150)

There was even the three holes to install the foot pedal control. I sourced all the pedal control parts for a BH92 backhoe. ($375)

The thumb is from Gentec and is part number HT824. ($1200)

I then took the tractor to a local hydraulic hose shop, who were able to custom make all the hoses and fittings for me. ($500)

This project seems expensive but is worth it in the long run. This tractor has served me well and I have no plans of replacing. See the pictures to show all the details. Hope this helps anyone that is considering adding a hydraulic thumb.

Man that’s awesome, nice job. How in the world did you fit 2 more hydraulic lines through there is what I need to know haha!

Nice!

VERY NICE WORK!
I have a professionally built custom thumb on my 2006 L48 TLB.
Yours looks every bit as nice!
You are likely already wondering how you did without it for so long.

I think $2225 is fine for total expense.
The original owner had mine custom made, and installed by the selling dealer ( combined with an excavator style Q/A BH bucket coupler ).
I would not be at all surprised if the cost for mine was twice your cost,.... and that being in 2006 dollars.

I had the same thought. Maybe 1/4" lines? I suspect he routed them outside the swing joint. I'd been thinking about using a diverter mounted on the boom to avoid more hoses through there, but this looks slick.

Now you've got me thinking about adding a section to my loader valve to get a third function. The Messick's part numbers lead me to believe it uses the same type Husco valve. I'll have to check it out next time I'm down there.

I did use 1/4" lines routed thru bottom boom. It is snug with all the lines, especially with all of em covered with nylon protection. No problems thus far. Have used the thumb a lot and love it.

I’m basically using the Raleigh L35 method just with a couple home made parts to save a few bucks, his was so flawless there is no need to reinvent the wheel
