Kubota M62 Cranks, Won't Start, Backhoe/3PH Interlock Issue (SOLVED!)

When you connected the backhoe hoses did you also change the two valves under the seat? Tractor deadheading the hydraulics?

Slime in stored or low hour equipment diesel fuel always a problem in warm humid climates that has to be considered.
That was exactly my second comment to him (on his youtube video) after mentioning the cut out, and to make sure they were hooked up and set right.. exactly.

That would be too much like tempting fate, not to mention being hard on the starter. 😄 What I did do, though, was to carefully roll over to a stump on a flatter part of the lot here, run the RPMs up to about 2200, and give my rusty backhoe skills some dusting off. It was a small stump, and old, and it came out in just three bites. Meanwhile, dark clouds were moving in from the north, and to stick close to the house, another stump, a pair of them, seemed like they also needed some attention. The small one was a manzanita, and came out in only one bite. The oak, on the other hand, had what was left of three trunks. After an hour of busting roots to dig a box around it, it still barely moved when I pushed it with the FEL. About that time raindrops were falling, the temperature had dropped into the mid 50s, and it was time for lunch anyway. After wasting the rest of the afternoon trying to figure out Medicare, I did crack a beer, on the back porch, but it was too cold and windy out there to sit long enough to finish it. Today I hope to finish with that oak, then head up the hill to see about digging the terrace I need for a new water tank. I have a feeling it's a much bigger job than I thought, so I'd better get started...

Something else to check on your Kubota, based on our chat today about you having that yellow ***** cat thing in your yard, don't worry, I won't tell them.... sheeesh ;) but I digress, here is the thing I mentioned on Youtube, figured others may find it handy as well so here's a link to the post I just did and a link to the video... it was originally done for a friend with no plans for youtube so forgive the shaking and poor quality, but good points none the less.

Try as I might, I haven't managed to break it yet. But I do have a slow leak on one of the front tires that's probably a bad valve stem. Kubota uses rubber stems in the front, so I'm going to track down some steel ones. Anybody got a recommendation?

So... talk to me babe.... you trenched... how did it go?

Good stainless steel bolt in off eBay for about $1ea. Tractors, trailers, trucks 🛻 get changed after having a rash of stem failures. Run Gempler’s bullet proof leak slime in the tractor fronts. High ply and extra deep treads on the M59 front tires.

Do think the air in the tire dose react some with leak stopper and requires at least yearly re-pressure in the first couple of years.

Interesting..... I have a slow leak in my front right, assumed it was just me...

Tried the crawl feature, but ended up just picking up the FEL a little bit then shoving the tractor forward with the backhoe. FEL back down and back to work. I thought the crawl feature would be perfect for making small adjustments when attaching implements to the 3PH, but it engages too abruptly and moves the tractor too far. So at this point I really don't know what it's good for, especially since it only works if you're sitting in the seat.

The ground here is really, really rocky, and about half of what came out of the trench was rock. There were places I couldn't get deeper than a foot before I hit really hard bedrock, so I had to call it good. But I needed to screen what came out of the trench to keep the rocks in the fill from puncturing the plastic pipe in the trench. So I made a set of grizzly bars with a little help from a neighbor. Most of the steel came from the junk yard...

I found a 12" trenching bucket at a used equipment dealer up in Medford, Oregon. That's what I was taking out of the VW van for that photo you remember. Saved way more than the cost of gas over the price Kubota wanted...

But that reminds me, I did bust a hose digging that trench. Steep hillside, a long way from the garage and no way to move it. A local shop made a new hose, but it was a real PITA crawling into all that hydraulic mud under the tractor to change it. Kubota lines aren't really that robust...

Glad you survived Snomageddon. Got a few inches here a couple times, but it was mostly gone by noon. Only the third or forth time in 13 years I've seen snow here...

Got a link to those valve stems? There must be a million of 'em on eBay and Amazon...

Sorry, that was over 10-15+ years ago. Always insisted bolt-in stems on the trucks and equipment trailers. Use as short as possible. Like the metal hex stem caps with o-ring.

Deep mud has taken out some rubber stems which makes a huge mess. Have yet to have a bolt-in stem failure. Mud, wood, rocks sure like snag a valve stem. Like the extra collar stem protectors on the rims the TLBs have. Sure would add to tractors used in the woods.

I agree, I have found zero use for the crawl mode.. .was hoping you had more success.. speaking of buckets... I found a seeeeeemookin deal on a WB bucket.. of all places, EBAY!!!!!! HUNDREDS dollars cheaper than my Arizona Kubota dealer... It was only like $149.00 for shipping/freight from Mass to NW Arizona (near Vegas).. amazing. Below is the feedback I left them..... HIGHLY RECOMMENDED if anyones looking for a bucket.. it's an authentic WB, it came with the tags and appears to be the real thing.

Check out the other goodies they have, from hoods to pins... rippers etc... they're my NEW GO TO SOURCE for my M62....

You're scaring the hell out of me with your over extension of your cylinders here... not my place to say it but personally you'd probably be safer having that bucket back halfway with the leading edge dug into the ground than with that cylinder reach... but I'm no expert.. you're not back dragging so probably good but extended that far, any impacts on the back end are going to be carried by those cylinder rods (unless you're laying it so far that your resting the bucket on SS system which I'd think can't be good for premature wear on the already tiny SS locking tips (mine are just barely able to hold the SS quick coupler on is it is, maybe yours are longer) ... zoykes...

I parked it like that only while changing out that busted hydraulic line. While digging, I dig the lower edge of the bucket in to provide stability and keep the tractor from slipping down hill. I didn't have the stabilizers down in the photo because the busted line was on that circuit. I was really nervous doing it there, but I really didn't have a choice as the tractor wasn't going anywhere as it was almost out of hydraulic fluid at that point.

You've re-instilled my faith in you. :) Can you elaborate on which hose you had to replace, I may get a backup made, thanks.

Looks like a pretty good deal to me! It's amazing what Google can find. When I was searching for that trenching bucket, it found Hunt Tractor in Central Point (Medford), Oregon. Kubota gets $969 for a 12" QUICK ATTACH TRENCHING BUCKET (K78720). They sold it to me for $600.00 OTD. Oregon doesn't charge sales tax, so while I was up there I ordered a thumb for the backhoe and a top'n'tilt setup from the Medford Kubota dealer. They shipped everything for less than the sales tax my California dealer would have charged. A while later I was visiting a buddy in Klamath Falls and picked up a couple fivers of SUDT, again no sales tax. But Oregon kills him with a really stiff property tax, and I couldn't take the long wet and snowy winters up there (though I did give it considerable thought...).

k... we need to talk cus that's my next purchase, I should buy through them, may be worth the road trip... (thumb and rear hyd)

I wonder if it's not better to have rubber stems unless you have valve protectors on the rims - it seems to me that a rubber stem getting hit may cause a slow leak, but a metal stem is more likely to be broken off entirely?

What a relief! I was afraid you figgered out just what kind of an idiot I really am...

It was one of the lines to the backhoe hydraulics, I think to the one that raised and lowered the boom. It was two years ago, and I'm a little fuzzy on it, but I do remember the 'hoe going limp and smelling hydraulic fluid. Here's a photo of the fittings the line connected to, taken inboard of the right rear wheel. I do remember pretty clearly what a PITA it was to get at it, though.

There are metal protectors for the valve stem on the rim. But when you don't notice that the tire is flat (easy to do because the sidewalls are real stiff and the tire doesn't look flat even when there's no air in it), the bead unseats and pulls the inside end of the valve stem inside the tire. I'm a slow learner, and it's done it twice now. I'm gonna take a chance and order these.
