FEL seems weak- how to check

Scuuussssseeee me sir. Typo. 4010. Loader was either a 152 or 157. Seem to remember the former. I know the cylinders mounted directly to the bucket because on one occasion I was digging out one of my ponds with it. Technique was to tilt the bucked all the way down and drive it into the mud till the front wheels came off the ground....slightly. Then put her in reverse and pull the muck out. Worked great for about half the job then in doing so, I came to a spot where "something went dreadfully wrong" and I bent the shafts on the cylinders. So they obviously had lateral pressure on the shafts. With my current tractor the cylinder pushes straight into a pivoting arm which does the moving as the other end of the arm is attached to the bucket. No bent rods with this arrangement and better force application.

Are the bucket cyl operating linkges on your tractor what you were previously referring to in an earlier post? I wonder if the previously mentioned linkages will help prevent bucket cyl rod bending when back dragging bucket with ft wheels lifted off the ground? Does bucket cyl linkage as shown in photo increase hyd pressure applied to bucket?
Back grading with the frt tires off the ground is a very good way to bend bucket cyl rods especially on a JD agriculture FEL with bucket cylinder rods fully extended
BTW JD 4010 rowcrop tractor had 84 pto HP.

using that technique is a good way to bend the rods on any loader, not just a JD agricultural loader

I totally agree but will the linkages in photo help keep rods from bending as easily when back dragging when rods are attached directly to bucket or SSQA?

Not sure if this problem took a left turn or what happened, however, change you hydraulic filter and check the fluid level. Still acting funny, get a pressure gauge on it.

I dont think so. I think what helps is loader with the linkage "usually" have shorter stroke cylinders.
The issue with bending the rod becomes the length of it. The longer the cylinder, the easier to bend.

Yes on the prior reference. Interesting you found a pic of my tractor faster than I could. Nice job.
Well on the hp I was going by the manual, not the Nebraska tests. Didn't want to err on the wrong side.....reduces the feedback flak. Mine was a diesel. After my LP 4020, I never bought anything but a diesel.
On helping to solve the back drag problem, they have to as the cylinder pressure is always in a straight line. On cylinder pressure, I'm not up on it but per you guys, 0 degrees is the highest pressure. What I don't know, nor how to calculate is the effect of the "force vector" via the arms that do the angle changing. Going to guess that you are dealing with a closed system and anywhere along the line you break 0 degrees you are in for a loss; 0 degrees defined as the bucket sucked all the way up...cylinder closed. In that position there is a short, straight line to the mounting brackets of the bucket. I don't have my specs handy on lift capacity at the arms, nor the bucket max-min, but I can drive it into a peaked pile of gravel, overfilling the (6') bucket and unseat the overpressure valve. But to do so it is really full and would be awkward attempting to move from the pile to the use location.

I'd bet Jim has a picture of an old JD loader that has the cylinders fully extended. Take that picture and apply back dragging to it and you can see the problem. From the tractor seat, I couldn't very well apparently....but I got half way around before I learned of my error. But that was back in 1991 time line and I was still young at farming.

I don't have a photo of JD loader with bucket cyl extended. All I did to find your tractors photo was perform a search using your handle(Texasmark)
