Update, I have not been able to drain the tank as of yet. I do believe the tank is plastic so the tiny particles and dark orange crap that has settled into the clear jar make me think it is crap from a metal container. The fuel I put in the freezer has not jelled or crystalized in any way, but I...

I will be draining it the rest of the way tomorrow once I get a empty drain pan.

The pump is after the filter. I did drain some of the fuel into a clear jar and noted a orange/ brown sediment that resembles algae in appearance. Aside from the substance appearing like a crystal, I am curious as to why it only gathered on the bottom part of the filter.

It was literally hard like a crystal. Now I need to find a way to bleed out the fuel pump.

So I am back to working on the 1990 L2850. I had a no fuel on cranking the other day, so I checked the fuel filter and found what you see in the pictures. I did not clean out the fuel tank after I bought it, so I am dealing with whatever is in there from the previous owner. Strange thing is, is...

Is the explanation just for an L2850 or are you speaking in general? I do not have a WSM, if you can share one I would appreciate it. All I have a general tractor book that I find rather general and not much help.

I am working on my L2850 and I have many little issues I am working out. I do have a question about the "Kubota timer 31351-31410". Can anyone give me a rundown on what to look for in a failing timer? Also can anyone confirm the physical location of the timer? BR

Is that the one that goes right in front of the starter? What are your thoughts on radiator hose inline heaters?

Thanks, My question was what everyone had experience with and any recommendations. I have an inline hose heater with a timer circuit to keep it on for 1.75 hr and off for 1 hr with another timer that I can set for four hours before I am to fire it up. I used this assembly on my last Jeep...

Does anyone have a suggestion as to what type of block heater or fluid heater works best for a L2850?

I ordered a new switch a week ago, but unfortunately I have to wait for the slow boat from Japan to arrive.

I think so too.

What is the " helper relay "? I have to pull off the two panels to get the switch out and verify the lugs on the back, and i found a source for a replacement with the same part numbers for $47. Since mine is sloppy and I have only one worn out key I am planning to replace it.

When I had it out I noted the post going into the plastic in the back are all loose. It is $70 to $78 dollars for a replacement from Kubota. I think it is time. Also just a few minuets ago I was trying to start the tractor and I let off the key and it continued to crank over.

Well to everyone an update. The battery is fully charged but there is still a drain coming from somewhere. I still get an intermittent crank no crank from the key, but I can get it to start right away when I jump battery to the keyed wire to the starter solenoid. I also noted that when it is...

Well the battery is two months old and is a Kubota replacement( cost $5 more than an Interstate), the cable from the positive to the starter is super heavy ( looks like 10mm), I also replaced the ground with the same wire and it terminates on the starter top mount bolt. I did not think about the...

I had already done that and measured 9 volts at the small wire with it disconnected from the solenoid.

I am getting the 9 volts from the switch wire on the solenoid with the key turned in the start position. I would think that I should be getting 12 volts to the starter wire from the key. I had to clean out the dirt and ice in the solenoid from the lug on top not having an environmental seal on...

Yes I have the intermittent no crank issue as well. I thought relay then I checked the solenoid. Now I plan to check voltage at the back of the switch.

The tractor I am dealing with is a 1990 L2850 Kubota. I originally thought I had a relay issue, but after getting a wiring schematic I do not see a starter relay. The issue is a voltage drop to the starter from the key. I am only getting 9 volts. I see where the key wire to the starter solenoid...
