    L3830 cold weather hydraulic issues

    Symptoms described match water in the system turning to ice. Running with ice can cause significant problems. I would get it enclosed and use heater(s) to get the whole machine above freezing. Then inspect hydraulic connections and filters for any damage or water. Replace hydraulic filters and...

    L3800HST TLB has me puzzled over engine shutting off. Any help would be greatly appreciated.

    Sure presents like a safety switch. You can get a free workshop manual in pdf at kubotabooks.com. It has a section just on operator presence (safety switch) to troubleshoot. Some of the switches are double hot and grounded. So you can't just jumper without looking at the diagrams first...

    Looking for a reliable Z121 starter motor

    Two starters would give me pause. The question would be is there an electrical signal or power to the starter after the start key is released. Or, did the starter gear fail to drop down because of something mechanical or grimey. I would run some tests both at the machine and on a bench to really...

    L3200 sight glass question

    Operator's Manual, page 54: Liquid level between top and bottom of sight glass when cold. Level may go higher than sight glass when engine has been run. As MapleLeafFarmer described above. There is some liquid left in the system when drained. So the procedure is not to dump in the book...

    B7800 with 600 hours over heating.

    Russell is right. Next time measure top of radiator and bottom of radiator. Concerning belt; Go to kubotausa on internet, sub directory parts. Put in model type and mower type, then look at fan belt number. If discontinued, there will be aftermarket belts that work. Take the belt number and...

    B7800 with 600 hours over heating.

    Rephrasing what other members have said. Measure the top and bottom radiator hoses temperatures using the infrared thermometer. If the temperatures are closer together, then heat is not being dumped and thus the overheating. Coolant has to be flowing for good cooling. If the inner cores are...

    B3350 won't start - safety switches?

    Sorry that you're having this problem. I don't think that posting how to override safety devices in an open forum is wise. Some of these switches have both +12VDC and ground separate circuits. Mixing those with an ECU could be pretty dicey. Look at the price on an ECU -and- the cost to install...

    Kubota radiators!!!

    A lot depends on what is being mowed or worked. I use the radiator genie and it helps. I'm going to claim the prize for most clogging. Brand of radiator doesn't matter. What I resorted to was buying another radiator. I swap back and forth between them to prevent overheating. Mine have to be...

    OEM service tools source?

    In particular, I believe that you are looking for a thin head wrench. Number of manufacturers and can be found at Amazon and some Home Depots. Very few tools, if any, that should ever be needed from Kubota.

    Spreadsheet on computer so that I can find it. Close to operator's manual table, but with actual hours and dates for cleaning, replacement, etc. A different notes document for memory aid.

    Main 9 wire connector B7100HST old

    Sounds like you are determined to match the original connector. Measure the dimensions of the shell, pin to pin spacing, sizes and types of pins. Then look at the connectors at eastern beaver on the internet. That connector is Japanese, used on motorcycles or sport vehicles. Modern connectors...

    Replacing 12 volt battery, B-3350

    1. Keep the same chemistry as the original (I assume lead-acid). That is what the charging circuit is designed to handle - other chemistries may charge differently. 2. Put the new battery on a full charge before using. 3. Same size battery. As good or more cold-cranking amps. Don't be...

    What years were the L3800 built and engines used.

    It's all relative. What would a new 38 hp tractor cost? How much would you use it? Can you do the work yourself or would you send it to a mechanic? What's a ton of money? Used to get hamburgers for $0.18 and now restaurants charge $25 (not fast food, anyway). Work on my own L3800HST, not hard...

    Fixing hole in side of block

    Using gas for heat is essentially what is shown in the video. Note that besides the hand hammers, the ring is moved under a drop hammer. Since the tractor welds seem to be breaking at the weld line maybe try using a ball peen hammer when still hot. It would compress the material for strength...

    Fixing hole in side of block

    Observation on welds. I understand that this is about experimentation, but consider this. Nails are purposely made ductile. They are also coated with zinc for outdoor use. Ductile means that strength is sacrificed. Zinc will make for poor welds, as it interferes with the bonding. Rebar comes...
