Kioti 7320 powers shuttle hyd issues

[WV hayseed]

I have a new Kioti 7320 with cab and power shuttle and loader. Took delivery with 3 hours on the tractor. Episode #1. Dropped the 3 point to hook up a mowing machine and it would not raise. Well already it is trying to fight me. Un hook it and check everything and 3pt will not raise. Called dealer, said a valve may be stuck. I pick the arme up bu hand to the top and they start working. Hook back up to the mower and go trim. Next day hook to my discbine. Go mow 15 acres and all is fine. Episode#2. Change fields and re-engage discbine at 1200 rpm and pot slams in and kills tractor. Increase rpm and same result. Increase rpm same result. The only way to engage it was to keep bumping the switch and when it started to turn kick it off then back on until it would take it without killing the engine. Called dealer, he has never encountered that issue. Called Kioti and no adjustment on pot engagement. I said their has to be a solution. Episode #3. Mowing on steep ground I notice the steering getting knotchy, steering wheel turns, stops, turns again, stops, turns. All fluids are on the full mark. Called dealer, asked the hours, I said 11. Dealer said maybe a plugged filter or pinched hose. I checked hoses. All seem good. Gotta get my hay in so keep running tractor while dealer chases problem with Kioti. I change filters at 20 hours and drain just over 9 gallon of fluid out. Book says 15.9, but it is a Korean interpretation so was that actually gallons or liters, who knows. I put 10 gallon of Permatran semi synthetic (great fluid) back in. Fire it up and check for leaks. Shut it down and check level, it is on full. Proceed to run tractor same issues. Call dealer. He stated the rubber coupler on the suction line may be leaking air. Tightened it. Same issue. Drained fluid again. Replaced coupler with an industrial one and industrial clamps. Same issue. Continued to run tractor. Steering getting worse uphill or down hill it won't steer. Episode #3. While trimming uphill tractor ceases forward movement, no hydraulics to lift mower, nothing works on the hydraulics. Coast to level ground and it works again. Hydraulic fluid is on full mark. Dealer comes over and checks pressures. They are fluctuating. He drained fluid and replaced Orin's on suction line. Same issues. Replaced hyd pump. Worked fine for a few hours then started same pattern of issues, however, I did not let it progress and burn up a new pump. Dealer replaced filters and hyd fluid with his brand, 10 gal to the full mark. Same issues starting up again. Dealer called Kioti. They stated it need 16 gallon of fluid!! Dealer came and dumped in 6 more gallon! This put it 65mm above full. Still having a few issues but not as severe as before. I now have 126 hours on it and am not comfortable running that far over full.
Anyone else having this problem and how much hyd fluid is in your 7320??

Sorry for your problems, I think I would have tried to return it and asked for a new one at 11 hours. Sounds terrible

Got one three weeks ago . 46 hours now no real issues. But I’ll be up for my 50 hour service soon . Then will see. Keep us posted

If it's not operating correctly then don't take it back from them. I'd also have them put anything in writing that they do that puts ANYTHING out of specifications listed in the service manual. I'd then look to work the heck out of it to force it to break: operating within normal limits of course, but AT the limits. If it doesn't break and it does what you need (w/o causing any headaches) then that's what you want.

I will say it is one of three things. Air leak on the suction side, restriction on the suction side (something rolling around someplace blocking oil inlet) or bad hydraulic pump. But that last one is not at the top of the list because of two separate pumps are being effected, so if not suction issue that I would guess restriction either in the transmission or between the transmission and pump inlet.

Well I have a really good relationship with the dealer and he comes to my house for most repair attempts. He has had the suction side completely off the tractor and we inspected it. Also looked in the hole in the tranny, nothing obstructing. 3 sets of new filters.
I delivered it to him with his rollback for this last attempt. He adjusted the steering pressure, as it was set low causing a hard to steer issue with fel attached. I also bought a brush bucket with grapple from him and he plumbed that in for me. It is just odd that he has another 73 cab on the lot and we compared everything to it and they are identical. I told him I know it only has 10 gallon capacity to the ful mark in the trans as well. The same trans and dipstick on the 73 non cab and 66 non cab he has beside it. Frustrating! At least my tractor steers better now.

 

[WV hayseed]

Mugeye, please let me know how many gallons come out and how many you put back in to reach full mark.

RandyT, I do work it. It was broken in pulling a 10 ft diskbine. Last 21 hrs has been brush hogging, and I don't mean mowing my yard. I am not as hard on it as I am my ole Hesston but it gets worked. I timber with the brush hog on the Hesston. Kioti needs a better seed screen on the front. I had to take a leaf blower to get all the crud out of the different coolers. I took a 5 gallon bucket of crap out from under the hood. I do take care of my tractors. When finished for the day they get cleaned and serviced.

I think you quoted the wrong person, I just said what I feel was the issue with the hydraulics. I didn't say you didn't work it, or abused it. Went back and reread you post about changing the hydraulic pump,

You also mentioned the 15.9 which I bet is gallons, since 16 liters is about 4 US gallon. So 16 gallon would be about right. I had issues with the hydraulic on my 45 a few years go after changing the fluid at 50 hours. After everything would get warmed up my loader would get jumpy and the steering would get hard to turn. Kept checking things and one day I pulled the dipstick for the hydraulic while the engine was running, and the oil was white but no water present in the oil and full of air bubbles. After shutting the tractor off, within a minute or two the oil would return to normal. Changed to another brand of oil and the problems went away. Basically the oil was foaming when hot

 

[WV hayseed]

Yes Sir sorry I got the wrong one. I don稚 have a foaming issue. It has had three different fluids in it. Original, Permatran semi synthetic and the dealer replaced it with Legacy. None of them produced foam. Just a very few bubbles at the worst.

I would just like to get it resolved. Great tractor if I can get this corrected.
