L3800 sick?

[bookemdano]

Dano,

I think my L3800 is running fine. However, if I am in the wrong speed range (always high gear) and try to start our or climb too steep a grade then I will loose RPM and speed. I can be running right along just fine and as grade increases I start losing RPM's. Most often I set it at the mid range for working and snow plowing. RPM's come back when I let off gas peddle and of course pushing the clutch takes all the load off and the engine returns to correct rpm's.

Good luck

This does it on flat ground, no load, and in low gear or medium. No place around here to use high. But that is exactly how
it acts.

Check the brakes to see if they are partly set on???

Forgot, I tried that. Put it on a hill, holding the brake on, put it in neutral and mashed the clutch, let of the brake and it
rolls free and stops when the brakes are applied. Don't think that's it. Got a better way to test them?

Yep, checking the brakes sounds too simple, but have seen this happen.


Mine never loses more than a couple hundred rpm and that takes a heavy load to do. No HST here though...

Before I took it in for service, mine didn't either. Makes me wonder about taking it in to be fixed now.
I mean, a simple warranty service should not have done this. If it's their fault doing a simple service, how
can they be trusted to do anything major. I will say, I went to this particular dealer because of their good
rep with everyone I talked too. I realize anyone can make a mistake so maybe bleeding the system will
take care of it. If this dang rain would let up so I could get a couple hours work in, I'd know.

Again, Change the Filter.

The bleeder knob is a small round gray knob just above the injector pump make sure it is closed (clockwise).. There is no fuel shut off valve on that particular model. I am not sure what the problem is but it sounds like fuel starvation.

Something similar happened to my 3540. The RPMs would go down to 1700 if it was set at 2200. In high range it would not get up to speed and seemed low on power.

I changed the fuel filter and problem solved. It was a year old with 100 hrs.

Dano,

I know you will get through this problem. I had a few issues with mine when new and around the 50+ hr. mark. You will really like the tractor in years to come. Just wanted to pass on a couple of things that bothered me with the L3800.
Suddenly it didn't want to start. I'm way out on my acreage, tired out, with a new tractor and it won't start. After a few tries and some time it starts. Next few day's same problem. So I'm ready to call my dealer and get help when I decide to regrease the HST peddle and hand wiggle it back and forth. No more starting issues! Turns out that the peddle must be centered up so if it isn't greased well it has trouble doing that.
Second is that little safety flip switch under the seat (the one the lawyers designed). During cold weather PTO on or off, SEAT up or down no matter, if I wasn't sitting on the seat the tractor would shut down. :hissyfit: I haven't figured it out yet but, when the tractor warms up then all starts working the way it should. :thumbsup:

Again I am really happy with this tractor,

 

[Recoveryhill]

Could you tell me what to
look for?
Thanks,
Dano

Forum wise I'd look for how to lose the all bold font? That's the second cousin to all Caps and kind of hurts my brain. (It brings to mind shouting)

You basically have a brand new tractor with a real problem. You referred to your dealer as a Stealer. Have they stolen from you in the past? Have you had a civil conversation with them about your problem? It doesn't matter if it's something they did or something else. You have a new tractor that doesn't operate properly and a negotiated solution should be well within reach. 120 miles is 120 miles (my dealer is 1,200 miles away) but if you are not working this out with Kubota's customer level representative, the Dealer, you are not taking the best route to a solution.

With all due respect, I'd get over the attitude with your dealer and find out how they and Kubota can assist in fixing your warrantied tractor.

I had problems with my 3800, it started fine but going up our drive it bogged and died. It lost rpm just like you said. My fault because it had summer fuel left in it and it was January, I added Power Service and let it idle for a few and then went on with clearing snow. I added 2 gallons of Kerosene and some 2 stroke oil and alll was fine. Now it has Winter fuel so I added Power Service but no Kerosene and it is fine. How old is your fuel? If it's not that then call the Dealer, they should be happy to take care of this and keep the good rep you say they have

Sounds crazy but I had a grader blade in the back of mine. When I set the height all the way up to lift it it took all the power from moving. Lowered the handle and tractor takes off. My lift needs to be adjusted for that. Same with my snow blower on the back. Lift all the way up and kills power to transmission. Other than that I agree with fuel filter and call dealer. Mark

My m8540 did that need too

Found it. Bleed it like the book said; open the bleeder knob, crank the tractor, run for 30 seconds, shut off and turn off the
bleeder knob. !st I did it cold, didn't work. Next I tried it with the engine warmed up. Worked great for about 3 trips. Old power
was back, no hesitation at all, rpm loss going up hill was like 2300 down to 2000. Then it bogged down again. Got off, opened
the valve, started and let run 30 seconds, shut down and closed the valve. Worked great again and was still running great when
I had to quit due to one heck of a thunderstorm that came up. (I'm clearing land. Each trip consists of me dragging 1000 to 1500
pounds of brush and logs about a 1/4 mile to an old strip pit hole where I'm dumping it) That pretty well narrows it down for
me. If it continues to bog down but clears up after I bleed the system, it's sucking air into the system somehow. It may be
cured but if not, I know what to tell the Mechanic when he gets here or I take it in. It sure felt good to have the old power back
in my 3800. I tightened the bowl as tight as it would go. It did turn a 1/4 to 3/8 inch.
May be a few more days before I get a chance to work with it again. Wife has me putting up a green house for her. That's going
to take several days doing it by myself. I'll let everyone know what happens when I do get to work with it again. Hopefully that
last bleeding done it. Sure would be nice if it did. Just have to wait and see.
Thanks everyone that had suggestions and advise. I appreciate it. And for those who don't like bold letters, well, I really don't care.
PC is BS. I use bold lettering cause I can see it better. Pure and simple. No one has ever accused me of being PC and no one ever
will.
Apologies to everyone else for the rant, but I am so sick of people wearing their feelings on their sleeve and demanding that
everyone else live their life to suit them. Again, it pure BS as far as I'm concerned. I spent 41 years not counting Vietnam putting
my life on the line 24/7/365 and I don't apologize or change for anyone.

Thank you for your service. All else fails change the filter.

Recoveryhill (politely) mentioned the Bold text... that has Nothing to do with PC, it is pretty much an All forum standard. Don't use it or cap locks always on. The backwards logic that it is easier for You to read, is a weak excuse, You should know what you have already said... those responding to you are Not using Bold, but yet you seem to be able to see.
Most folks complaining about having to comply with PC, usually have problems complying with SC, (societal correctness)...

Disconnect your hoses from the filter housing, clean the ports with compressed air and install a new filter. Unless your filling your tractor up straight from the pump you could be adding all kinds of trash into your fuel system. Have seen it many times.
