I picked up a 5000 Flexicoil with a 1720 cart last summer. I used it for putting on fertilizer last fall. The auger turns fine until I put fertilizer through it. Then is slows right down. Took about 45 minutes to fill both tanks. The unit looks well taken care of but I can’t figure it out. The previous owners said they were using a tender or broadcasted fertilizer on prior to seeding, so they hadn’t noticed.
It has 1” hydraulic lines from tractor to the back of seeder and then 3/4” lines up
to the diverter. Then 1/2” to blower and 3/8” from diverter to auger motor. Blower works like it should. Tractor is a JD 9300. Called the local JD dealer service head but he hasn’t returned my call. Any input would be appreciated.

I’m not familiar with Flexicoil but does it help if you turn up the hydraulics on the tractor? Is that how you set the fan speed? I know on our Bourgault tanks when you have the fan running faster for heavy rates the auger is a lot faster than it is when the fan is running slower for lighter rates? Possibly could be an internal leak in the motor?

I used to have a 1720 but darned if I can remember specifics on the auger except make sure it's latched or it will tip down on the front and bend in half!
Most carts behave as kevlar mentioned, they need flow to make the auger run right. I ran mine with a 876 versatile and stock hydraulics, it was a very good tank.

I think your hydraulic orbit motor seals are leaking ? That would slow dow the pump capacity.
On my bourgault cart I had to change orbit motor seals every second year .
Only other thing is maybe you have an air lock in the system.
Check your out put on your 9300 hyd outlets incase a hydraulic coupler is broken

Does the motor slow down or does the product flow slow down? If product flow slows down the auger is worn out inside the tube. Have seen that on several older tanks. You pull the flighting out and 1 foot up the tube the flighting is 1/2 the diameter it is at the hopper.

what kind of fan rpm were you running?? thatll give an idea on flow, on my 2320 i used to run fan at 4300 ish and the auger worked really fast i could load 2 products in 30 min and be on my way, buddy used to run fan even higher and he'd have to turn down the hydraulic flow in the cab to keep the auger from shaking apart then turn it up to go again
my thought is with flighting is wore or the hydraulic motor is wore out inside the oil is by passing inside, does it work better when everything is cold?

What rpm is your tractor at while loading? Bumping to 1000-1200rpm makes a big difference on hydraulic flow while loading.

I can’t remember the rpm on fan. We increase flow when we are augering and then decrease it when using the fan. Used it last fall so I don’t think it was cold. |

I took the motor apart and it looks okay but JD service guy thinks they know better. He wants to take a look at it.

I took the motor apart and it looks okay but JD service guy thinks they know better. He wants to take a look at it. As you had stated the auger turns fine when empty but bogs down/runs slow when augering fertilizer. For one thing I bet that auger is horribly rusty on the tubing as well as the flighting and not having been used for years would not have helped matters, however as you used it last fall some of that should have polished up. As to the hydraulics it would seem as though there is decent flow at low pressure, the question would be if there is good flow at high demand pressure and sure would be nice to have a flow meter to tie into the loop to watch pressure and flow that the auger motor is receiving. Had you tried another circuit on the tractor or hooked another tractor to the unit to see if that made any difference ?.
Some years ago I had the swather reel seeming to be rather gutless and stalling out although turned fine speed wise when not loaded down so I took the motor off and brought it to a hydraulic shop and while they did not tear it down they tried testing it in whatever way they had available and said it tested ok although not perfect. Rather than mess around with that motor and of course its all specialty items as the hydraulic shop did not have access to that motor style, I bought a new motor at the dealer and there was a noticeable difference in performance. I will never know what it looked like inside though, that may have shed some light on why it wasn't operating at peak performance, hard to say.

kinda what I'm thinking there northern farmer, i changed out my auger motor on my 2320 cart only as the seal was leaking once we got it apart the shaft was wore so much as we figured a new seal would only be a temporary fix so i bought a whole new motor and it never skipped a beat after
my swather had the same issue for the piggyback hyd pump all the sudden it wouldn't run the reels or canvas's, it would when oil was cold for a couple seconds but then slowly move after, took pump apart and it was all washed and wore inside the oil was bypassing like crazy

The divert valve for the fan/auger is a pretty simple unit, but it wouldn't hurt to try bypassing it in case it is leaking internally. Just connect the auger hoses direct to the tractor supply for a test.

The JD technician said it looked good but there is one section where the output shaft goes through that’s full of holes where I guess the oil sloshes through. Can’t really see what that looks like. My buddy has a spare motor lying around with same shaft size and bolt pattern so I’ll try it.
Forgot to mention motor gets hot while in use. Leads me to think there is a bunch of bypassing going on.
