UPDATE: B3000 - moved my BH77 closer to the cab: MOVED IT BACK OUT

[randu]

Bandit67 Just got the seat today and have it installed already. I had to do some seat bracket mods, kubota was 7 1/2 x 5 1/2 bolt spacing and the new seat was 5 x 5 inches. I have not cut the 2 1/4 of the stand yet but will wait and see when I get the extension out . I am going to take the 9 inch extension out tomorrow but just wanted to get a feel for the new seat configuration. Your right it's tight, I sure don't want to gain any weight. It looks like everything will fit together from the measurements I have taken. I am 5'11", 200 lbs with a 36 " waist and a 30 " inseam and I figure I am at the maximum size for this mod.

Hey Randy,

I had some sort of old fiberglass faced plywood laying around for years from an old dog box project I did way back when that is extremely durable and holds up better than standard plywood in the elements with a couple good coats of enamel paint. Boxes were used mostly during the winter months for the sled dogs, and took all sorts of abuse from snow, road slop, etc. without breaking down. Just can't remember what the heck that stuff was called. For the backhoe seat bracket, I primed & topcoated with Krylon enamel to match the Kubota Gray.

2 sets of mounting holes. 1 set of 4 holes to mount the plywood adapter plate to the Kubota seat frame (7.5 x 5.5) using factory Kubota seat bolts and 5/16-18 x 3/8" T-nuts, and 1 set of 4 - 5x5 holes to mount the new seat to the adapter plate using 1/4 x 1 1/4" hex bolts. Used plywood because I don't have much in the way of metal fab equipment. $2.30 worth of hardware from Home Depot to get the seat mounted.

Oh, yeah, I added a couple of washers as spacers between the Kubota seat bracket and new adapter plate on the 2 rear-most Kubota seat mounting bolts (closest to the joystick controls) because I didn't like the forward tilt of the seat. Used washers only because I wanted to see how it felt, and may end up cutting some full length wedges that span the entire front to back length of the factory bracket, just to make a nice clean install, but the washers are working fine at this point.

I cut the seat post down with my old Harbor Freight Horizontal/Vertical Metal Cutting Band Saw.

Once you're done, post up some pics of your setup...

I used a metal plate for the base, I also have the Harbor Freight band saw. I will post pictures when I finish.

Here are three pictures of my shorten backhoe conversion. The first one is the original, the second is the original with the new small seat and the third is with the 9 in extension removed and the seat post cut down 2 1/4 in. This was done on a B2650 HDSC. I want to thank bandit67 for the inspiration and his work and showing me the way to do this. I might also modify the seat plate to get it a little closer to the cab. Hope I get the pictures in the right order.

Nice! Looks good!

Now maybe you can help me. I see you've done the hydraulic thumb mod. That's something I've been thinking about doing. Would be curious to know what you did, parts used, etc. Or point me to your build thread if you did one...

Let me look it up and get the details. I just used a 12 volt diverter valve with an on /off switch. Its not as good as the factory setup but they don"t offer one for the B2650. There was a person that had previously did this that I copied. Not really expensive and very easy to do .I think I can find it by tomorrow.

I got most of my info from this thread
http://www.tractorbynet.com/forums/build-yourself/125912-custom-hydraulic-backhoe-thumb-3.html

It started around page 3 and I looked at bumperm's posts. I think all the info is in that thread, I have a parts list somewhere if you can't find them in that thread.

OK, I had seen that thread recently. Unfortunately the pics are no longer available, so I thought I'd see what you came up with if you've done it more recently. Sounds like the hyd. cylinder Bumperm used was too short, so I guess I'll search for one that is a couple inches longer, as I don't have the tools to modify the cylinder on my own.
If you found a better fitting cylinder when doing yours, I'd appreciate the info on that one.

Thanks Randy.

I used a cylinder from Surplus Center 9-4945, 2 1/4 x 10 1/2 x 1 1/4 for $99.50 in June of 2014. I used this on my BH 65 first and then moved it to the B2650. It worked for both backhoe's without problems. I also have a spare diverter valve since I had bought them in a pair. If you want I could sell it to you for my cost? Hydraforce SV!0-24-6T-N-12DS

I'm trying to do the opposite move my seatback for leg room .I'd like my home to sit a little bit away.i can counter weight with suitcase weights up front.
I bet subframe is different from cab models to non cab.dont have a cab and mine was designed to turn tractor seat.i hated that and added the Johnny seat and straight levers.now I want a bit more leg room .I'll figu
