  1. I have a 2005 4410 sprayer with just over 5k hours. Previous owner said one hydrostatic pump has been replaced (not sure which one). Today I started noticing some wonky things, I'll list them in the order I noticed them in. Also the dealer is coming out Monday to diagnose the problem. I figured I'd post it on here and see if any had any thoughts, or if nothing else I'll post what we figure out to help someone else out. (this all started happening when I was nearing the end of my load, so the sprayer was hot) #1 I noticed the chemical pump stopping and starting again when stopping and starting driving. (mph, not rpm) #2 Then I noticed the sprayer being pretty sluggish when using the hydrostatic lever. I was working around poles so I was doing a lot of starting and stopping. It felt kinda like I was spinning out, but I wasn't. And with the speed pot at it's minimum, and the lever at it's maximum, where I used to get 9mph (if I remember right) now I was only getting 4-8mph. (Sometimes 4 sometimes 6 ext,) #3 I switched fields and noticed I was only getting 26mph, and slowly work it's way up to 29. Where before it was 32 bang on everytime. #4 With the engine idling, the ladder won't quite raise all the way. But as soon as you rev the engine it'll come right up. Which speaking of the ladder, the ladder does not fail the "real" ladder test. (Pot speed 100%, rolling at 5mph, go full speed with the hydrostat lever, the ladder doesn't move at all.) The sprayer on the other hand takes an eternity to reach full speed. (or 29mph) I did notice however, when I was rinsing the tank. That when I do the ladder test with chemical pump on, the pump pressure will drop down to 15 or 20psi. Unable to stay where I put it. We used a infrared thermometer on what I think was the case drain on the wheel motors. The dealer said if the swash plate is messed up it'll bypass a lot more fluid. They were all within 10°(F) though. We're kind of suspecting the left side charge pump. Because from following lines it looks like that's what runs the chemical pump and maybe the ladder? Couldn't quite tell though. But honestly nothing quite makes sense to me.
  2. Hi guys, In an effort to find the answer on my own and not have to rehash a topic that has surely been beat to death, I have searched this forum and some other places, but to no avail. Either I can't find the answer or I'm not smart enough to understand the answer.... so, here it goes. (Also, thank you for the help with all my other 886 woes. You guys are awesome!) I have abandoned the PTO pump and mid-mount valve and plumbed the loader lift and tilt direct to the remotes on the 886, purged the air and topped off the hydraulic system. 1 - Loader is gosh awful slow. Is this normal for the little tractors? 2 - Loader won't lift front end of tractor off the ground. Hardly takes up slack in loader pins. 3 - I can hear a "relief" sound at max cylinder stroke going up and when fully tilted. 4 - PTO is strong if that means anything. 5 - 3PT seems to work as usual. 6 - Steering is strong and sequels hard on full turn like it always has. 7 - TA shifts strong, brakes are very good, everything responds fast and well except the loader on the remotes. So, where do I need to check pressures, what order do I check them in, and what other info do you need to tell me what to do next? Don't worry, I'm almost done with this thing, I think, and will quit pestering you guys for info soon, we all hope!? After that, it's off to the hobby ranch for a slow painful death.... Maybe for both of us....
  3. I recently changed the hydraulic filter in my 574. Before I did this I had no issues at all with the hydraulics. Now I can't seem to get the filter primed back. I have actuated the lift controls over and over again to try and bleed the air out of the system. I don't have any pressure and I can't hear my pump whining like it use to. Do you think it's possible I had a weak pump and finally just went out upon trying to prime back this time? I've NEVER had this much trouble after a hyd filter change. Below is a picture of the filter. Dry as a bone. Not getting anything into the housing when I start the tractor up. Thanks in advance for any insight.
