New forum member - watched for several years, and finally joined so I could seek some wisdom from folks more knowledgeable than I am. I may be in the wrong aisle, but have three questions (for now) about the L2900. I've had mine for about 6 years and mostly used it with a box blade, disk and bush hog. It's a 1998 model, GST, 4x4, about 515 hours and generally in pretty good shape.

1). AIR FILTER. The one I'm replacing is open on both ends, and given the configuration of the housing, it's got to be open on both ends for the spindle to go through it and the cover to screw on to the end of the spindle. The "official" replacement is a TA040-93230 but that has a cap on one end. I assume it would be a bad move to buy a no-name Chinese knock-off on Ebay (and hope it fits) just because it's open on both ends, so would like to find a decent air filter that fits. Because of that spindle through the middle, I assume there's no "inner" filter on this one. Any ideas why the "correct" filter is incompatible with the housing, and what filter to use?

2). 3 POINT HITCH. I changed out the UDT fluid (with "official" Kubota UDT fluid) and filter when I bought it at about 300 hours, and recently -- at about 515 hours -- the hitch (with bush hog attached) became stuck in the upright position. It will raise and lower a couple of inches but won't go any lower than about 80% up. I've manipulated the knob under the seat every which way, and that hasn't made any difference and it's "open" counter-clockwise all the way at this point. I changed out the UDT fluid and filter again (and replaced the crappy, leaky sight glass while I was at it) but that hasn't made any difference. No physical obstructions and the change-out ruled out a clogged filter, etc. Any ideas what to do?

3). LOADER. I hear this is the lament of a lot of L2900 owners. I should have found a tractor WITH a loader instead of buying one and then trying to find a loader. The LA480 and LA481 are nearly impossible to find, and I've had zero luck. The Westendorf equivalent is about $12k plus shipping (twice what I paid for the tractor in the first place), the Koyker is only a little bit less, and the others are "iffy" about whether they would fit an L2900 and also prohibitively expensive.

Any input would be greatly appreciated. Thanks in advance for your thoughts!

The air filter you referenced is for the double air filter.
I think the one you want is shown below.

2). 3 POINT HITCH.

Make sure the feedback lever (part 200) and associated linkages are still connected properly. No missing split pins (cotter pins) and such.

#1: You're looking at the wrong fiter #
Single filter is a T0070-16323

#2: Feedback linkage issue

#3: You already know the answer, sell it and buy a tractor with a loader. ;)

if the 3pt will partially lower the lowering speed valve is fine. As NIWM says focus your attention on the feedback linkage.

Folks, I really appreciate it! Gonna order the “correct” air filter today, and will check out the feedback linkage hopefully before the weekend. Will let y’all know how that turns out. Thanks again!!!

Folks, I really appreciate your help, and all issues are resolved except for the three-point hitch “stuck“ in the uppermost position with only a couple of inches of travel.
Here’s what I’ve found so far. Between long work hours and dodging thunderstorms when I’m off work, I just got a chance to get the seat off and figure out how to take the knob off the lowering speed adjustment shaft so I can get that piece of sheet metal off. The “control arm” moves along with the position control lever, including the two big hex nuts all the way up against the side of the valve body. That’s on the left side of my photo, and of the diagram pictured. On the other side of the valve body, to the right, none of that stuff moves along with the control arm. There’s a hollow in the far end of the feedback lever and I think I can feel the head of a shaft in there, but that doesn’t turn either when the control lever and control arm are moving. I’m not sure what’s going on within the valve body, but I assume the feedback lever should move along with the control arm on the other side of the valve body. I’m sorry I’m talking at about a kindergarten level, but that’s about the extent of my understanding of hydraulic mechanisms. Any ideas you’re willing to share?

It sounds like you have a problem with the feedback system but I really don’t understand what you are trying to describe.

You do not show any pictures of the rear end of the feedback system that should be attached to the short arm of the lift system as shown in the diagram.

There is probably a Work Shop Manual (WSM) at this site:

Please focus on describing the movement of the feedback rod as you move the control lever to maximum height and then to minimum lift.

Thank you, Russell!

I got rained out shortly after I took those pictures, and it looks like rain and lightning is set in for the rest of the afternoon. I’m hoping the weatherman is wrong, and that I’ll get a chance to look at it again tomorrow, and will try to describe it better and get better pictures. Thanks so much for your willingness to help! Y’all have a great Saturday night!

The feed back linkage does not move with the control lever it moves with the position of the three point arm.

Thanks Wolfman!
I assumed that same shaft came out the other side of the valve body. Hopefully the weather will cooperate tomorrow and I can make more headway.
Nice to have you folks willing to share your expertise - thank you!!!

Its a 3 piece assembly that allows each end to move independently and alter the position of the spool in the control valve:

Position control crank - 060
Feedback crank - 140
Connecting link - 050
