B2320 I want to increase the lift capability

First of all, I never told the dealer WHAT capacity I wanted, just that I wanted to know if I could increase it by changing the cylinders. I didn't mention the load I had already lifted. He said I'd blow the pump so I asked if I could change the pump too, and he said that is the only pump they make for that machine. He said you can get anything you want from a hydraulics place but kubota can't and won't do it.
Second, the logs I might have to move from time to time I would mill as I have a poor man's version of the wood mizer made by lumber smith. If the trees are any good, not rotted or diseased, I want the longest timbers or boards possible.
Finally, I just put a skid steer adapter on the tractor to attach a tree scoop for a couple dozen of my young trees needing to be moved. The attachment plus the weight of the adaptor probably exceeds that of the bucket. So I lose some lift capacity. Kubota lied to me about the adapter. All the following occurred on the phone. They told me they didn't make the adapter for the B2320, they changed and redesigned the B2320 and called it B2301 and IT has the skid steer quick connect but it wouldn't fit my tractor. I told them someone on tractorbynet told me the B26xx with the LA504 loader has the same dimensions as mine but they said no. I told them I think my information is good and I was looking at a picture of the SSQA. He still wanted to deny it but I convinced him to measure from pin center to pin center and told him I had necessary measurements like from center of tilt piston to center of other tilt piston so he goes out and measures from edge of tee on cylinder to edge of tee on other tee. Know I know he being kind of a d--k but I let it pass as I had written down enough measurements to extrapolate the measurement from the points he measured at and turns out the loader they told me wasn't available for my tractor in 2010 does in fact have the right dimensions for the ssqa to fit. Then I was looking in my kubota manuals for info on the hydraulics, any specs that might be helpful for the load increase like what cylinders are on the machine and I happen to catch a line in the front loader assembly book that says the following instructions are for the optional LA504 loader, the same friggin one they told me that didn't exist when I bought my tractor new in 2020 which was also when they could have sold me the ssqa and the LA504 instead of trying to screw me out of more money further down the road when I needed a skid steer attachment. I won't spend any big money with them anymore. I don't like even the slightest hint of greed in business owners and the people I dealt with are the family owners of the dealership. They do good work but they screwed me. I'm poor and can't afford to fill the pockets of people who own multi million dollar businesses.

Your poor. Ok. Why not sell your late model 2320 and buy a 15 year old farm tractor that can lift 1400 pounds if that is what you need to do.

Thanks for all your help GP, I'm truly in awe of your willingness to share relevant information.

Seems like your looking at a lot of information that is either inaccurate or you're misinterpreting it.
The la304 is the only loader that Kubota approved for the B2320, doesn't mean others might fit, just means if you're buying it from a dealer together then that's the loader you're supposed to get or else the dealer could be liable for damage etc.

The la504 is the factory loader for the B3200 and B3300su models, these are much larger frame tractors then the B2320 and was never an option for the B2x20 series.

In 2010 there wasn't a ssqa adaptor listed from the factory for the LA 304, there were aftermarket one and adaptors to that used a pin type quick attach system.

Your your la304 boom cylinders are 1.57" bore x 13.2". The LA364 boom cylinders are 1.77x13.7, not sure if they would fit.

You were able to lift that heavy concrete block because you were most likely low enough to the ground that it was still in the breakout force in the lift arc, that area has a higher capacity, the lift capacity will decrease the higher you lift due to the loader geometry.

As to increasing your lift capacity, you can possible put a LA364 on the b2320 but that would be pricy.
The factory relief should be set to 2000psi, check your pressure and if you'd like, set it to 2200 (10% increase is the highest I would go).

I understand the desire to get more lift, however pushing too hard will result in some expensive repairs.

TMGT, thanks for the courteous response. I appreciate civility instead of combativeness. I'm not an expert on all things tractor but I know enough to get myself in trouble. I used to be a stubborn mule about asking for help, now I'm a stubborn mule who asks for help.
All that being said......I will try to attach a couple photos of certain information from my 2010 B2320 Tractor owners manual and L304 assembly instructions manual. These photos should clear up why I mentioned the LA504. Also, so far about 15 people have responded with the suggestion you made about resetting the pressure relief but no one has given instructions beyond saying something about adding #10 washers. I'm reasonably sure I can find the pressure relief valve and I know what #10 washers are but unless it is so obvious as to where the washers go or any other adjustments to be made, I just hoped someone would explain and/or post a photo of the valve with where to place the washers and where to adjust if its some nut adjuster or whatever unless the washer goes where the nut adjuster is. Maybe they could point at it in the photo. Nobody has posted photos unless I missed the post.

To see discussions on the pressure check procedure just type in, kubota pressure change , in your search engine and you will find many references including a bunch of links to TBN on past discussions/instructions on the topic. I also attached a link to a kit for the Kubota B tractors to accomplish the task. In any event good luck in your efforts.

I thought I said piston diameter, sorry if I typed otherwise. I thought piston diameter would be enough info
