Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it’s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users’ profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses – Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it’s related to a horse for sale, regardless of who’s selling it, it doesn’t belong in the discussion forums.

Stallions – Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services – Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products – While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements – Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be “bumped” excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues – Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators’ discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the “alert” button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your “Ignore” list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you’d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user’s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum. These rules may be amended at any time to address the current needs of the board.

  • Kubota B7800 won't start: UPDATE first post

    My Kubota died on me yesterday, in a neighbor's yard of course. Put it in neutral to move something out of her yard, and it cut off like the safety switch had kicked in. Now it won't restart. The dealer is an hour away, no trailers available to get it there, and no-one around here can figure it out. Looked online, and it seems there is a recurring problem with the safety switches. I've jiggled everything, made sure all was in neutral, checked connections, tried jump starting--nothing. Just hoping someone might have some ideas for me!

    UPDATE: Tractor is back home, working fine. It was the safety switch under the forward/reverse pedal, it had broken. No idea how, something must have gotten thrown up there just right. Five dollar part, much more for labor and hauling. I want to go to tractor school now.

    Very likely a microswitch that has either failed or isn't "caught" by whatever it guards. With my smaller BX22, it's sometimes the PTO lever that needs to be engaged and then disengaged if the machine will not start. If you hear any "ticking" or other sound when you do turn the key, one of the microswitches is likely to blame.

      Not familiar with that tractor, but if it has a switch under the seat that kills the engine when you get off/fall off, that is most likely the villain.

      Male a jumper wire and bypass it.

        Thanks, I suspect one of the safety or micro switches too. I just don't know enough about machines to know how to bypass them. When you say make a jumper wire, do you mean take any old wire and stick it in either side of the switch? I can try that. I've already disengaged both PTOs and tried to make sure the hydrostatic pedal is completely neutral. When I turn the key, I get one click and then nothing.

        Sure makes me feel like I wasted my money at a university when what I really needed were some practical skills!

          rather than bypass a safety switch just use a meter to check the switch's condition, if it is at fault replace it.

          Do not bypass a safety, they are installed not as a source of bother but as a safety to keep you from harming yourself

            One click?

            I doubt that it is a safety switch.

            I don't know how your tractor is wired, but my experience with JD is that if a safety switch is involved, you will not get any clicks.

            The reason being that the safety switch is located in the circuit in such a way that ZERO power is available to the tractor.

            I would suspect a bad battery or dirty battery terminals or posts.

            Checking the battery with a volt meter is not sufficient. If the battery is suspect, you need to clean the posts thoroughly by removing the cable clamps, cleaning the inside of the clamps as well as the posts.

            Then put the battery on a charger. When it is fully charged, put a load meter on it for the period required and see what the load meter tells you.

            A battery can test 13v on a voltmeter and fail the load test.

            If the battery checks out, then trace the safety switches one at a time.

              A jumper is the quickest way to prove a fault.

              I doubt OP has the ability to determine whether a safety switch is faulty.

              My suggestion is meant to determine the problem. Whether one bypasses permanently or for only a few seconds is their option, not my business.

              I would say that when testing, one should be in the seat and not doing something dumb like standing in front of the rear wheel.

                This is exactly how I would deal with it and have. I have found most problems tend to be pretty simplistic. I always start from the basic and work up. My engineer friends always want to approach it from a complicated side. I/we are assuming that when you turn the key nothing happens, doesn’t turn over? Start with the safety/idiot switch, pull off the wires on either side of the switch, either jump them with a wire that has alligator clips on it, or tape them together if they do not have a plastic cover making sure there is good metal to metal contact. Or take a small finish nail or something of like that will fit in the ends and push together. If still nothing happens check the safety switch on the PTO and or make sure it is turned/pulled off. Maybe a bad switch that won’t turn off. Disconnect the wires to it and tape the ends. Check and make sure no wires fell off any where.
                I have by passed all of the seat safety switches on my mowers. They are a PIA, one always has to get off and on to move stuff. Having to restart the thing numerous times when mowing takes time and puts a lot of wear and tear on the starter and the battery.
                Most mower have hydrostatic transmissions these days so they don’t move when started out of the seat. And most have PTO safety switches that won’t allow the mower to start when engaged. If an operator can not tell when the mower is engaged by the sound they shouldn’t be operating it.
                If this doesn’t work get back. Or call the repair shop they may give you some basic advise.

                  You may or may not get power to some circuits with the seat safety open. I can start our tractor with the seat safety open, but it will not move unless the safety is closed.

                  Our lawn tractor needs the parking brake engaged to start if the seat safety is open.

                  Jumping the seat safety is easy, the others not so easy depending on where they are.

                    Just unplug the switch, do not pull out the wires. Get a small piece of wire and jump the pins in the plug to complete the circuit.

                      Always start with the battery and its cables.

                      Not doing so is akin to taking the engine apart and then finding out the fuel tank was empty.

                      And don't forget to check the battery ground wire attachment to the frame.

                      I had to completely redo the one on our lawn tractor. Vibration would work the factory attachment loose.

                        Thank you, everyone, for all the good suggestions. I wouldn't permanently bypass the safety switches, I was just trying to get it started long enough to get it out of my neighbor's yard. Alas, nothing worked, and I had to resort to getting it winched up onto a tow truck. I didn't feel quite so dumb, though, since the repairman they sent out to get it couldn't start it either He tried the jump wire on the safety switches and even on the starter--got it to turn over a few times, but not start.

                        Certainly a learning experience for me. And again, thank you all for your help!

                          Had a fuel solenoid relay go bad on our JD, a learning experience for sure. Would crank, but not start. I now know far more about our tractor than I ever really intended. I won't even get into taking the 3 point apart...

                            This wouldn't work on my Cub. They are female ends with plastic covers. Simple to pull off insert a small finish nail to connect the 2 wires. I have never worked on Kubotas. I only buy what I would like to think are American brands. Hard to tell these days.

                              Let us know what the problem was. In case I ever get a Kubota.

                                I sure will! It may take a week though, the shop is backlogged.

                                  Yes, please keep us informed! I have the same tractor and I want to know if there's a potential problem lurking. It sucks to have it happen but at least the service guy couldn't start it either. I always feel a little vindicated when none of the simple fixes they suggest to "the little lady" doesn't work out for them either.
