hyd control valve on 3 pt

[clemsonfor]

winston, My system doesn't have the B like in the link you posted. I assume the B is where you are indicating the relief is. There is nothing under the big shut off screw.
My filter screen is clean. Since I've had this tractor, I changed the hyd oil, Last yr I changed over to Transmission fluid.
I shut the big knob off and the 3 pt holds.

At idle with big knob all the way out. the 3pt will drop. It will raise back up at about 1500 RPM

I think I solved the slow loader issue. When The tractor is first started in the AM. loader speed is great. It seems like I lose some loader speed after using the tractor for several hrs straight. I think the oil is getting hot and thinning out causing me to have to run higher RPM to get the same flow. I think I'm going to experiment with thickening the HYD fluid some (maybe add some STP) and see if that helps with the thinning of the HYD oil when it gets hot.

Clem, I intend on keeping the tractor even though I'm looking for a larger (50-55 HP) tractor . So, I may as well have it working right. I think they have those valves made in china. Probably why they go bad so often. LOL

Carey063, I have no idea what you mean by a kenmac/ winston thread. I have read and appreciate all the comments. I didn't comment about the dirty suction ,because I know it's not dirty.

dump that transmission fluid and put some 303 fluid into it. You don't have to throw it away, catch it in clean buckets. Any heavy equiptment site would have some they would give you free. If I was closer I could give you tons that my loggers go through.

303 fluid was on sale black Friday at TSC for $16.99 a bucket!!!

Yes, I believe as it gets hot, The fluid thins out too much causing everything to slow down.
At first, I thought it may be something to do with the 3pt control valve. After using the tractor first thing in the mornings, I really noticed how well the loader works until it gets hot.

It did the same thing with the JD303, which is why I switched to transmission fluid.
I believe tractor Ernie used transmission fluid in all his yanmars and never reported any problems.

wasn't Ernie in the Pacific North West or was it Pennsylvania? Penn would be closer to the souths climate in the summer but the PNW is nothing like your climate down there.

Well, I guess now it's a Scotty, Clem, and winston thread.. LOL

On a serious note. Yes Scotty, My thinking was /am, I having 2 separate issues being caused by the 3pt valve, but I really don't know for sure.
I am going to replace that valve as soon as Fredricks gets them off the boat. LOL . Maybe, just maybe, replacing the valve will cure both of my issues.

As stated earlier. When I first start using the tractor /loader I can lift a full bucket of what ever at around 1800 RPM. As the day progresses, I have to raise the RPM to about about 2500 to raise that same bucket full.

Clem, The loader did this same thing with original JD303 fluid I bought from JD dealer.I paid more than that for it at JD.
Only reason I changed to transmission fluid was to see if it made any difference . Nothing changed, I get the same results with transmission fluid as I was getting with JD303.
I still have the JD303 fluid in buckets somewhere .

After adding some STP to the mix, I was able to lift that bucket full all day at around 1800 RPM.

It's about to start turning cooler here, so It may be next summer B-4 it's hot enough outside to notice any change in loader performance when fluid gets hot.

If the new valve don't fix it. I'm going to load it up and take it to Fredricks and let them fix it. While I'm there, I can look at some of the Mahindra tractors he has

I have read a not so stellar review of a Mahindra tractor on another forum I am on. Everything from cylinders leaking to metal parts needing re welded, bucket quick connects coming off causing damage to pins in the traN's mission coming out causing the loss of low range. If interested PM me I will send you a link. I know they dont like links to other forums here.

There are similar posts here. Enough to give me second thoughts. Mahindra sources tractors and components from all over.

I would study which models are best, before considering one. None of the modern tractors are as simple and bulletproof as what we already have. Or as owner-maintainable.

 

[winston1]

I would put a good word in for the Kioti. My Bobcat is a Kioti with Bobcat written on it. It has been a dependable machine. It is a 2008 model so their might be more electronics now but not much more than the older Yanmars on the 2008 model. I too have heard some bad feedback on the Mahindras, mostly to do with electronic controls.

 

[kenmac]

Yep, I have heard bad on them all with all the DPF, sensors, etc,.
As ya'll may remember. I bought that new Z turn Kubota only to burn the engine up @1.9 hrs.
Kinda hard to know what to get until you get it and just hope you encounter no issues

After I posted I thought and the guy I'm thinking of cross posted the same thing on this forum as well. So the same story is here. I just can't remember his name. I will find it thought when I have time.

 

[kenmac]

wow ! just googled several brands. Kubota, Kioti, mahindra, LS and JD.. They all had issues.
I believe one could google xxxx Tractor issues /problems and what ever tractor you inserted would come back with complaints.

What's a guy to do ? You can't google any brand, without some type of issue: HYD, DPF, engine, transmission, loader, 3 pt lift, etc, .

Stay with old simple reliable, time proven designs! haha. No electronic diesel controls, no filters and sensors that derate your engine cause they don't like whats coming out of the pipe.

I wonder if part of what we are seeing today in the tractor market is just what happens when new designs are driven by the home owner consumer market instead of the traditional agriculature market. Those old Yanmars - even the little 13.5 hp models - were originally designed for doing real work on small farms on difficult terrain. They had to work for a living, and a 35 year old Yanmar is still up to the task. In their old age they get retro-fitted with a loader for retirement chores, and they'll still be around pretty much unchanged decades from now.

You can see the same thing in old US farm tractors; they last forever too. But since the US farms were larger, our old farm tractors are just too big to be as handy as compacts. Mowing the lawn with the old 2 cylinder JD is a bit of a chore even with power steering.

Add to that no fuel lift pump, no fuel shutoff solenoid needed when you have a compression release for emergency shutoff, a $20 manifold pre-heater instead of a glow plug in each cylinder, a mechanical tachometer, some models that cool fine with no water pump, and my favorite - instructions for owner-maintenance of the injectors with a wooden stick and mutton tallow.

Apparent simplicity, made possible by elegant design.

Yep all of that too. I just didn't go on and on! Simplicity is the best option especially something that may sit a month or three between startups.

....... owner-maintenance of the injectors with a wooden stick and mutton tallow.

what?

 

[California]

It's in the YM240 Service Manual, paragraph on periodic maintenance of the injectors.

Scraping out carbon without damaging the sealing surfaces.

How about the part about changing the filter ever other oil change!!! Most of us would never even think about doing that for the $5 or less one costs . But I would imagine filters are easier and cheaper to cone by than in rural Japan 35 years ago.

 

[California]

Seems to me that the less frequent filter change is because there's no dust in rice paddy work.

Extreme contrast: some early big ag tractors specified daily oil changes! Several gallons.

Clemsonfor, do loggers simply dump on the ground when they do an oil change back in the woods? I found this near our mining claim with the equipment still parked nearby so there was no doubt who did it. Because it is national forest there had to be a government inspector visiting occasionally. Apparently the loggers had no fear of pollution fines.

NO!!! and that is not just my PC answer!

What year was that? Late 90s at the latest maybe? They use 5 gallon buckets to catch it all. Of course there is drips and spills like when they miss the bucket or swap a bucket but 99.5% of it is caught probably. If I catch something intentionally spilled I make them dig it up and take it with them...what they do with it then is their own responsibility. That said I have heard of some military installations that made them dig it all up and prove that they took it to a licensed contaminated soil dump site with a receipt. Also in the winter lots of waste oil is used to start fires and is burned off. But us in the forestry side of things burn lots of gallons of fuel , gas and waste oil in our torch fuel. Also when they bust a hose or something and send gallons of oil all over the place to me that is just part of the job, I do not make them clean that stuff up, it would be near impossible and I really think its accepted as "collateral damage" in logging. Some of these rougher loggers that run old stuff and just don't take the time to repair leaky hoses and connections will go through 5 gallons or more of 303 fluid in a day. Its so spread out though the common person never notices it. If the loader is really leaky it stains the spot it sits pretty bad.

Seriously I take intentional dumping very seriously, even more so if rain will carry it off with surface water directly to a creek. Accidental spillage that is small gets a pass, and i'm talking small spills, not like if you accidentally knocked over a 5 gallon bucket.
