Kubota B2650 and B3350 info and hints

[DelSc]

The Kubota website lists the B2650 PTO HP as 19.5, and the B3350 as 27. I haven't used the B3350 (I have a B2650) but it seems like you would notice an extra 7.5 HP at the PTO. I chose the B2650 it for its simplicity over the B3350, but based on the specs, I think the B3350 engine is making more than enough additional power to overcome the loss caused by the extra emissions.

A blocked DPF can cause a power loss, but otherwise it shouldn't have a huge impact, certainly not in a way that would make a 33HP engine less powerful than a 26HP engine (it could very well derate a non-DPF 34-35HP engine down to 33HP though). DelSc makes a good point about the PTO horsepower numbers -- those are advertised numbers and Kubota would get in big trouble if it lied about that.

In reality, having an HST is more of a hit on effective power than a DPF would ever be. Most people deal with it OK.

If you have a backhoe, you might have heard rattling coming from the "bucket level indicator". This mechanism is a somewhat complex linkage of bell cranks, levers and rods, with several attach pivots. On my tractor, those pivots had a fair amount of play that allowed things to rattle. The fix was easy, adding a nylon washer on the inside, a thin SS washer on the outside.

The B3350 is my first cab tractor. Where I live it gets hot in the summer and cold in the winter (imagine that) and in the summer, can be calm one second and a wind blowing >40 knots the next (thermal tripping off nearby causing inrush) from any direction. I worried some about leaving the cab door/s open when parked in the sun for fear of wind damage. And leaving the doors closed with A/C off (engine off) is not appealing either, as you gotta get back in that over. The fix: A short length of nylon cord tied to inside door latch. The cord is long enough to go past the "over center" of the gas spring past the point the door wants to open with the spring. To use, attach hook to door bar which then prevents door from opening all the way to become a "sail" in the wind, while still allowing convenient cab ventilation.



When not in use, hook can be left on, and doesn't interfere with door latch.



Can be left hooked up on the right door, if you don't use it often for egress.

Here's a good thread on adding hydraulics on a mechanical thumb (my post is #36 in this thread):

Please see above thread for more construction details and pictures.

Got a letter informing me of a HST plug "recall" on my B3350 (purchased Nov 2013.

Dealer said transmission fluid needed to be drained to replace this plug and I would need to leave the tractor with them (a pain due to logistics). In the letter, Kubota under warranty allows 30 minutes of labor to replace plug - - that doesn't sound like it would include R & R ing hydraulic fluid to me.

Anyone had this done? Does anyone happen to have a part number for the plug - I'd rather just buy the plug and install it myself.

thanks,

Did your letter contain any specifics such as serial number range and/or whether or not it pertains to the B2650 as well? Or was it just a "Oh hey, your tractor has a recall..." type of letter?

I didn't get a letter but was told by service tech that a plug and a battery cable recall was sent to them and they have the parts on hand but they had to do the service . That was a couple months ago and it hasn't been done yet .

The letter mentioned my B3350 tractor by serial number, no range given. Not sure this is the same HST plug issue as with the 2650, but I would assume it's the same tranny. Nothing about a battery lead. My letter is a couple of months old.

Hello guys - its been a while since I was up here chatting about the Kubota 2650 - anyhow I bought one however regretfully I'm going to have to sell her before i get to use it. Both my knees are out and I just can't hardly get in the machine. She's brand new I think just 4 -5 hrs for when they put the bucket backhoe on. She has been sitting in my garage.

Its a wonderful machine - It has everything heat air the works.

I have $40K in the machine and I'm willing to scarafice it for best offer. The machine is in North Georgia 2 hours N of Atlanta close to Blueridge ga.

My number is 540-353-1965

Thank you Guys!

Mike

Wow I wish that i could buy her! But unfortunally i don't have that much, but I would love to have a tractor with a heated cab.

Mike,

Dang it, that's terrible news . . . I'm assuming you seen doctors, they can do amazing stuff with surgery or replacement parts. If you get well enough, would the tractor still work for you?

I would approach selling the tractor as new. Talk to the dealer and see what kind of price they would give you in taking it back. With the lack of hours, they could sell it essentially as new. It looks like they delivered it to you and you just parked it.

If the dealer wants you to take too much of a hit, then list it on eBay and/or Craigslist. I sure would have a high reserve on it though, just guessing, but you shouldn't have to take more than a 5 to 10% hit.

 

[RCMEDIA]

Thanks guys - yeah they started going out a few years ago - and 6 month ago they really went bad - its killing me to let her go - its a beautiful machine.

 

[trollingfever]

what a beautiful looking machine!

I finally got my B2650 last week and have been busy working on modifications/improvements/upgrades to make the tractor work better and be more to my liking. On of the first things that I did was swap the hydraulic couplers for the hydraulic chute rotation on the snow blower from being run off the dump/curl function of the loader valve to the third function. This eliminates having to get past the detent in the loader stick to get out of regenerative hydraulics and allows for much easier control of the chute rotation to the right. All that was needed were a couple of 3/8 ISO B female couplers, 3/8 X 1/4 npt reducer bushings and a couple of 1/4 npt street 45's. I will be using the loader valve's dump/curl function to control the cylinder that I am adding for control of the snow blower chute.

Farmall45b,

Good thinkin'. I understand the regen issue, but it seems more intuitive to me to move the joystick left/right for rotation. I'm using the 3rd function buttons for chute deflection.

Not taking issue with your approach as I clearly see the merit . . . just not sure I can reprogram what few active brain cells I have left.

 

[Farmall45b]

I had no 3rd function on my B2320 and used the dump curl for the deflector and manual rotation. I guess my brain is already programed for this setup.

 

[Farmall45b]

One of the first additions that I made to my B2650 was to install a radio. I bought a Pioneer digital media receiver from Wal Mart for $32. It has a AM/FM tuner and also aux. input and USB input. I don't have a smart phone, but it is supposes to be compatible with I Phone and Pandora. For those who are wondering, the install was a piece of cake. Simply remove the plastic plate covering the empty radio slot. Behind you will find a connector for the radio and an antenna plug. The radio I installed came with a metal case that the radio slides into. This case fit the radio opening perfectly and had a bunch of metal tabs that you bent up to retain the case in the opening. Next I took the plug that came with the radio and used solder splice connections to mate it to the pigtail harness that my dealer supplied me with. This allows the harness from the tractor to adapt and plug in to the Pioneer radio. Plug everything in and slide the radio into the case and everything is good to go. Pretty simple and very worth it. The radio and speakers sound pretty good. It is pretty easy to hear during normal operation, at full throttle and road speed the hydro whine gets pretty loud making it pretty hard to hear the radio when set to a reasonable volume. For most applications however it work quite well. Here are some pics for those who are interested.

 

[Farmall45b]

Here is the hydraulic chute deflector that I built for the front mount snow blower. I could not justify the crazy cost of a kit from Kubota, so with the help of the fabricator at my shop we built this. It runs off the dump/curl function of the loader joystick, but could just as easily run of a third function or rear remote. It bolts to the existing holes in the chute. Not that we built one, we are thinking we may build more if there was interest from other folks in buying something like this. Wondering is there is any interest in buying this as an add on kit or buying the brackets and adding your own cylinder and hoses.

 

[Chad450r]

Nice work, and yes the Kubota kit is over priced



I did mine like this, as to save the 3rd function for my hydraulic toplink. The blower on the front and box scraper on back is the best snow set up I've ever had.
