Glad to hear you got it figured out. By the way, the pedal you've been mentioning isn't a gas pedal, its your hydrostatic drive engagement pedal.

On my L185 you push the throttle all the way back and then down low below the right side of the dash there is a small lever that you pull up on to shut the fuel off and kill the engine. Then don't forget to shut the key off. Don't turn the key off with the engine running.

Possibly the pump is gone but it sounds like it was putting out enough pressure to blow a hose. Maybe its simply an airlock? It should self prime but maybe try loosening a fitting on the loader and then applying hydraulic pressure to that fitting and see if any air comes out. You might have to...

Hmm, maybe there is some kind of short or something in the solenoid circuit. When you say "press the gas" I'm assuming you mean the accelerator pedal operated by your foot. Maybe try just using the hand throttle in case the foot throttle linkage is causing some kind of electrical issue that is...

OK, if you think the solenoid is fine, you can disconnect the power wire to it and then run a separate power wire from the battery to it. This will isolate it from any of the shut downs tripping it closed. Then try running the tractor and see if the problem persists. If the problem disappears...

The shim thickness required should be the same as the amount you need to loosen the bolts. If that helps.

You can't run it without having the solenoid in place or you'll have fuel leaking as soon as you turn the key on. But you can test the operation of the solenoid simply by: 1. Shut off fuel petcock. 2. Disconnect wires to the solenoid and unscrew it from pump. 3. Reconnect wires and ground the...

I don't know if a B7800 even has a fuel shut off solenoid, but regardless, it sounds like a fuel starvation issue. Lots of times a diesel engine will idle just fine but die or run rough as soon as you place any load on it (such as engaging pto) or try to increase the RPM. When was the last...

Start with the simple things. Is there fuel in the tank? Is the fuel shut off valve open? When was the last time the fuel filter was changed. Have you checked for fuel flow to the injection pump? Fuel to the injectors? Is there any smoke out of the exhaust while cranking the engine over?

Yup. A classic case of you get what you pay for.

All engines vary in oil usage depending on engine condition, type of service they're used for, type of oil used etc., but no, they don't use more oil as a rule. Generally though, they do hold more oil than a comparably sized gas engine.

Yeah, a lot of Kubotas blow air forwards. It keeps the hot air away from the operator and cuts down on exhaust soot collecting under the hood. Its probably correct.

Yup, 80w90 gear oil is exactly what you need.

If by hydro, you mean the hydraulics that run the 3pt, yes you can use sae 80 gear oil. Yes it is all the same reservoir. Some slight foaminess is normal if you checked it shortly after running it, but if it is milky at all, its contaminated with moisture and needs to be drained / flushed /...

To me, this sounds like you've got a fuel line collapsing. Maybe that's why it only happens when warm and the line is soft due to heat. I'd look real close at the fuel line, especially between the filters and the lift pump. It might be forming enough vacuum to collapse the line??? Does it do it...

To get water in either the pin or vent, the axle would pretty much have to be submerged. Maybe the PO sunk the tractor? The other possibility is condensation build up over the years. I'm not 100% sure, but I believe the the front axle pivot pin is actually lubricated by the oil in the front diff...

Yes, bleed the lines at the injectors. The cap on the fuel tank has nothing to do with getting air in the lines. The only way air can get in the suction line to the pump is either your fuel level in the tank is too low, a loose connection in the fuel line / filter assy. somewhere or possibly a...

You keep saying you used TSCs hydraulic oil in the trans. If its a straight hydraulic fluid, drain it out and replace it with either a universal TDH (trans, diff, hydraulics) fluid or 80w90 gear oil. You don't want to use straight hydraulic oil in the trans.

I know how everybody gets sensitive when it comes to oils on this site but I'm only going by what Service Dept Vic says in one of his videos about Trans oil changes that is posted on here. Basically he states that if you don't have a FEL, then you don't need to use UDT in a standard trans, but...

If its a hydrostatic transmission, use Kubota UDT or equivalent in the trans. If its gear driven, use 80w90 gear oil unless it has external hydraulics added to it, then use the UDT. Use 80w90 in the tiller.
