New 1100 cranky start/Bed won't lift

Good day. I have about a 2 week old RTV 1100. Has been running beautifully up until this afternoon. It came with a hydraulic commercial straight blade installed. I'm taking it in next week to have some accessories installed. I removed most of the hydraulic blade components myself, as I am finished with the blade for this year, and want to put the brush guard back on the unit. I unhooked the electrical connectors and the hydraulic hoses from the front hydraulic blade unit.

Then, when I went to start it, it was very difficult to start. Took several tries of holding the ignition on. Finally caught. It ran, but with very reduced power, and the hydraulic bed won't lift now. I had successfully used the bed lift just a couple hours earlier. Hmmmmmm

I can't imagine that removing the hydraulic blade unit from the front caused this, but I did nothing else to it.

Would appreciate any assistance from anyone. I know about as much about this stuff as I do nuclear physics. And I'm a fish biologist, so nuclear physics isn't my strong suit. Thanks. RR
 
Hi Rem, I don't have the 1100 - only an 05 900 with the hyd bed. I have just gotten a Kioti tractor with remotes though. According to that tractor manual, if one of the remotes is engaged it could be harder to start and would have reduced power when running. Of coarse this is just a possibility- but maybe something to consider- Maybe a lever out of place??? Does the bed work independent of the blade and with a different control? I don't know how one of these sit ups look but did you have color coded hook ups the blade hyd connections go to? Good Luck . Bordercollie
 
Thanks for your response.

All I did was disconnect the three hoses coming from the front of the vehicle directly into the hydraulic blade unit on the front.

The bed control is like a parking brake handle just to the left of the driver's seat.

I dunno ... it has to be hydraulics but I don't understand why disconnecting the blade would have caused this. Could be a coincidence and something totally unrelated is wrong.

I'm uncertain as to what you mean when you refer to "remotes". I'm really new at this stuff.

Anyway, I'll contact the dealer on Monday and see what they say. Poor guy (Kubota). He'll have a quiet day tomorrow.

Thanks again. RR
 
I have an 2008 RTV 1100 with a plow but not the same as yours. Is there some place that you need to hook the three hoses to? Maybe under the front carriage.

Thanks for your comment, Randy.

I have covered the ends of the hydraulic hoses with a clean, durable covering and secured them to the front of the vehicle. We will find a more permanent spot for them when I take it in next week.

There is no evidence of leakage from the hoses or under the carriage. And the hydraulic fluid level in the reservoir tank is fine.

I'm just really at a loss as to what has caused this. I'm beginning to think that my having removed the blade hydraulic unit was a coincidence to the other things happening.

I have prepared an email to the dealer explaining all and will send it tomorrow. Then I'll drop by there late morning on Monday after they've had time to digest it, and I have had my now departed filling replaced. Maybe they will have an answer for me right away. I dunno ...... Must be something I ate or whatever. Thanks again. The old guy is gonna power out for the night. I'll let you know what I find out as soon as I find out something. RR
 
Looking at the build your Kubota website they have listed a hydraulic removal kit listed,maybe something has to be inserted or connected into the hoses when you uncouple them?? If they gave you the plow installation booklet, it might be in there.

I believe you will find you are dead heading your hydraulics. Is the lever to operate the plow in neutral position? May need a coupler for 2 of the hoses to allow them to loop the pressure back to the tank.
 
The remotes are where a person "plugs in the hose{s} of extra hydraulic equipment. I agree that the hydraulic flow must be part of the problem. The fluid probably needs to circulate on around. Other wise it will just sit in the lines- so of like a kinked water hose. The fluid .reservoir may get over hot if the oil can't circulate. I wouldn't worry- I imagine it will be a simple fix. If you use it though keep an eye on that reservoir temp. In the past tanks have melted from excess heat.Bordercollie
 
Rem, I forgot to ask... Do these hoses quick attach(the push and release fitting) to the RTV? Most equipment I have seen - the hoses stay with the implement- don't know about plows though. Also make sure the control lever is indeed in neutral. Bordercollie
 
It does sound like hydraulic to me. As members have mentioned, it may be necessary to loop-back or bypass the flow to the plow.

Not mentioned but worth looking into. Is there a "float" position for the plow that needs to be used when the plow isn't installed? This is the same type of "float" that your cargo box has when you push the control arm all the way down where it locks in the float position.
 
Good morning. Well, here anyway. Thank you for all of your responses. Completing the flow "circuit" makes sense to me. I have tried most of the other suggestions, save that one.

I think I'll just leave it alone for now until I contact the dealer. I'll get direction from them and proceed from there. I hope it is a quick fix, as I suspect it is, but I don't want to cause additional damage.

I think I'll go ride my motorcycle. It's almost above freezing here and is supposed to soar up to 48 or so F. Awesome. I'll take what I can get.

Thank you again. I will most definitely let you know once the problem has been determined. Obviously the biggest problem is me. RR
 
Well folks, you will be pleased to know that I have, upon your guidance and support, corrected the problem. I once again perused the operator's manual
(Duh !!!!!) and found that it is indeed necessary to reconnect two out of the three hoses to each other. This obviously completes the circuit and the bed lift began to work immediately.

I hope I didn't do any damage in the meantime. I'll start looking around now for someone to blame. My wife will be awake soon.


Thanks again for your suggestions. I'll have the dealer check everything out after I explain to them exactly what my wife did. Bye for now. RR
 
Nuclear Physics

Rem you need to be careful about discussing Nuclear Physics. One nite I walked into a bar and sat next to the village drunk. He looked me right in the eye and said let's talk about something. I recommended Nuclear Phusion. He asked if I knew why when a cow took a dump it was a big round pile on the ground; when a horse took a dump it was a bunch of apple like dung on the ground; when a sheep took a dump it was a bunch of round berries on the ground? I of course said no I didn't. Again he looked me staight in the eye and said: You want to discuss Nuclear Phusion and you don't even know sh__!
 
Point taken. Only two of the many things at which I excel in knowing nothing about.

But at least I won't repeat that particular hydraulics mistake again.

As an old aquaculture instructor once told me .....

"You are going to occasionally kill fish. But never kill fish the same way twice".

Apologies for the digression. RR

muleman i was thinking the same thing . when we would build cranes (hydraulic cranes) one thing that would shut them down was a sticking valve. i would check to see if them hose do need to be connected with a union and if you connect them and it still has the problem you could go back and start checking the valves or controlers as some call them. my wood splitter has a sticking valve and it bogs down if i don'e release it nuthing major but if it happens on something else like a rtv it could shut the engine off or even burn up the pump. if i remeber correctly hydraulics really don't do anything until you restrick them. when they aren't being restricked the oil just free flows but when you stop off one end of the line thats when the rams start movin. now if your boggin down i would say it's a hydraulic issue. is there anyway to put a inline pressure gauge ?maybe mount the gauge in the dash that way you can watch your pressure when workin. i don't know why the rtv'as don't have pressure gages we put them on all the cranes they can tell you if something is wrong right away.
 
It's all good now. Turns out I had to connect two of the three hoses that were supplying the hydraulic blade uint up front. The manual indicated which two. I guess it completed the circuit. I mentioned it to the Kubota dealer and he wasn't aware that was necessary, either, but it clearly was. As soon as I did that, it all started to work. He's working well now. All good.

Thanks for all your responses. Cecil (the Diesel) rocks !!!!
