Ford Jubilee locked up after hitting rock with brush hog

[FERNHILLFARM]

I was brush hogging and my Ford Jubilee locked up after hitting rock with brush hog. It instantly shut off and the start button won’t compress, I can’t shift out of gear, can’t lift the brush hog. Basically nothing works and I don’t know what to do. I tried taking the brush hog off but the PTO is locked and won’t turn.
I did use a Jack and lifted the brush hog up and ithe rock is not stuck in the blades.
Thank you for any help on what to do!

get the pto shaft off the tractor some how sounds like you busted the gear box that's the first place i would start

I don't see how the start button has anything to do with hitting something with a mower.......may just be time for a change and accidentally coincided with the event. Normally Hogs have shear pins in the drive line, sacrificial element, a 1/4 to 1/2" bolt, that break before any damage is done to anything else.

As Mario said, disconnect the mower from the tractor. Figure out why the start button decided to crap out at this time. Once you get through that, even if you have to bypass it to get the tractor started, put the tranny in N and push in the clutch.

Does the tractor start or not.

The PTO is locked up which in turn locks up the transmission so it is stuck in gear. so block the tires and jack up one rear wheel till it is off the ground and rock it while trying to take it out of gear

I saw that happen once. I am with Marlow bent/twisted shaft, broken gear in tranny. Also the collar that puts the pto in gear.

Good idea old, but he may have damaged something.

 

[RobCons]

May have broke something but I have done the same thing and freed it up by rocking the tractor.

If the Jubilee is like the rest of the older N series, the push button has an interlock that won't allow it to get pushed in when in gear. If something went kerplunk in the tranny, rear end, etc. & has the drive line bound up to the point it won't pop out of gear, there's no pushing that button.

Sounds as if someone may have forgot to install an Overrun Clutch on their PTO.

Mule
Thats just what i was going to write
I have a feeling there is some thing broke.
you always use a Overrun Clutch on your PTO
running without one is a big NO NO

Over-running clutch wouldn't have helped in this case. A slip clutch or shear pin was what was needed. Over-run clutch is for when the tractor comes to a stop, but the implement is still running at speed.

Maybe disconnect brush hog PTO from tractor for starters. Possibly to avoid confusion and reduce variables.

In your panic, did you forget to push the clutch pedal to try and shift the tractor out of gear?

Very simply put the tractor's driveline is bound up. The weight of the tractor is pressing against the rear tires, and the force is traveling up through the wheels into the transmission, over to the PTO, and out to the mower, which is somehow jammed and can't turn.

After you jacked the mower up off the rock, did you try to turn the blades? Could there be something else jammed in there, kicked up by the rock?

Next thing to try would be to get a long pry bar, insert it in one of the PTO knuckles where it will allow you to put some pressure on it, and attempt to turn it backwards. This might allow a helper to get the tractor shifted to Neutral, and once that happens all the pressure will be relieved.

Do you have another tractor, or any sort of vehicle you can hook to the rear of this one and put a little backwards pressure on it? You're not trying to drag the tractor, just put some pressure on it, so you don't need a big tractor or truck. Even a small car will work.

I don't have a Jubilee, but have had similar experiences when my tractors stalled suddenly when the mower encountered a super heavy load (like tree branches, rocks, stumps etc.) The tractor could not be started because it was in gear and the PTO was on. I could not turn off the PTO or shift out of gear because all the gears had been jammed together because of the sudden stop.

The first time this happened a got a neighbor to come over and try to pull the tractor. As soon as the pulled tractor moved a couple of inches, the jammed gears loosened enough for me to turn off the PTO and shift to neutral. When this same thing happened a couple of more times over the years I was able loosen things up just by rocking the tractor slightly (sometimes by only shaking by oversized butt like I would if I was trying to rock a small boat)

Bingo.

Sounds like what he should have on that mower is a stump jumper. My woods M5 mower has a slip clutch and a stump jumper on it.

Absolutely! Some people do not know what an over-run clutch does, apparently.

This is why a slip clutch is recommended on several types of PTO equipment . While it would probably not affect this situation. A tractor with transmission PTO should also have an over running clutch .

"Over Running Clutch": If you had a locked up gear train, like with a "transmission driven PTO" (vs a "live", or "Independent" type) the implement shaft follows the transmission output shaft which is locked to the rotation of the tires and if you are running at a certain PTO speed, tractor moving across the ground at a certain speed, the whole drive train is locked together and when you cut the engine throttle, the PTO RPMs follow what the rear tires are telling the drive train to do.....keep on turning, not follow the throttle control position.

Translated, If you are running along and think you are going to stop by pushing in the clutch and attempting to shift into N, it isn't going to happen until the whole train, implement included, has slowed to the point where your desire can be accomplished.

An Overrun clutch is a sawtoothed affair where by in one direction you are on the vertical part of the gear train and have direct drive, the power direction. But when the driving force attempts to slow down, you cut the engine throttle, the sawtoothed portion of the clutch rides up and down the slopes and vertical portion of the clutch allowing you to disconnect the drive part of the train from the driven part.

Same thing in marine engines.....when you accelerate the gear train is locked together. When you decide to slow down, the overrun clutch in the lower unit allows the engine to do what it wants to do while the clutch allows the propeller to follow the force acting upon it by the oncoming water. Were it not for that, if you were tooling along at say 35 MPH and decide to abruptly chop the throttle, you would be getting your teeth out of the windshield.......no brag, just fact.

Its the afternoon, hot outside, got the chores done I scheduled for today, nothing else to do so I though I would annoy you guys with some "folklore'.

Sure it would have, if not seized and properly adjusted for the tractor/mower combination. That’s the whole purpose.
