 Topic: 1955 WD45 Diesel and 4 bottom plow
Posted: 28 Sep 2020 at 4:22pm |
Hello all,
I am in the process of taking on a new field that needs to be plowed up. The only plow I have around is this ole 4 bottom snap coupler. It has been at least 40 years since this plow has been used so I went out and got 4 new shares, new tire and newer hydraulic ram. I also spun the wheels out a touch to match the furrow.
I have one problem that I need some help with. When I unhook the plow there is a massive amount of pressure on the hydraulic line. What am i doing wrong? I seem to be missing a step in terms of relieving pressure. I let the plow down as far as it would go and there still seems to be a ton of pressure. The only thing that works is to press on the fitting (or hammer it) to get the fluid out and I hate doing that.
Eventually I would prefer converting this old unit to a 3 point hitch and putting a 2 way hydraulic ram on it - but grandpa is really excited to get this going again so here I am!

If you are using a modern cylinder on the tailwheel with one way hydraulics, the other side will have to be vented. Using two on my D14 with 82S mower with one side vented and no problem

Oh my, if that’s an origional WD45 it appears to be in excellent condition! If you turn the tractor off and wait a minute is it still difficult the unplug the hose?

If it has a ‘transport’ valve, that may cause what you’re describing, depending on how it is set.

By golly, I do believe I see the "transport valve" with it's little knob right there under the seat.
One of my tractors has one but I've never had anything to use it with.
I will be interested in why and how it causes Damon's problem.
Damon, Those big fat tires sure do give that WD-45 a "mean" stance! LOL

Any chance they are the original Good Years? Maybe second set? Good looking 45!

Thank you for your tip on the transport valve. Can you explain how these work and how I might get past this issue? Another member noticed I have one right under the seat!

My great-grandfather owned an AC dealership in the 50's. He bought this brand new in 1955 and they are the original tires.

Yes this is an all original WD45. Rebuilt the engine in 1990 - only around 100 hours on it currently and it runs like a top!

With that plow your transport valve should be turned out( counter clockwise) and pump set for traction booster control. Linkage from drawbar to pump needs properly adjusted too. Spring must be present from hand clutch cover down to draft arm. You will have no hold position like this. Just run with lever fully up. With lever full down there should be no pressure on hydraulic connections anywhere.

The purpose of transport valve is to bypass oil to rear lift cylinder while lift arms are lifting front of Implement a bit to transfer weight without the rear raising too.

Thank you for all the info! So with my current setup, if I need to run the plow down the road, i would want the transport valve turned clockwise all the way in so fluid runs to the rear wheel cylinder? Then when I get to the field, I would need that valve turned counter clockwise to run the plow?
What is the best method so I do not have a ton of pressure on the plow hydraulic line, when disconnecting? It usually comes off the valve ok, but the pressure in the line is extreme and I am unable to hook it back up as the ball valve is not movable.

When using TB position,the transport valve is out all the time. Raise lever to top of quadrant and total plow raises. In the field you run lever a thumbs width up from bottom. More if needed. Sounds like you need to read the operator's manual.

The only function of the transport valve is to DELAY the raising of the tail wheel. You do NOT need to change it during transporting down the road or plowing in the field. Your problem is not there. There are several things you are not telling us. ONE Dose your lift arms go down when you lower your control lever when engine is running?? Dose your cylinder retract at the same time, it should?? If not you could have pluged return. Could have a bad tip on your hose end or on tractor coupler. Also, if you leave your plow out in the sun all day the oil will expand and create a huge amont of pressure in the hose. Give us more detail and we can help.

Thanks again for the info. All the things you are describing is normal for my tractor. I have ran our D14 and WD45 for many years, so I don't think I need to "read the operators manual". The problem I am having seems to be a plugged return or delayed setting. Sorry if I seem completely uneducated to you but this is why I am sharing my experience on here - lots of great information and fun group to chat with.

I will give as much detail as I can on my issue:
1) When I push the hydraulic lever up, the lift arms go up all the way - then my cylinder goes up after. So the transport valve seems to be working correctly. 2) My lift arms do not typically stay where I set them, they slowly creep down - this is a setting on the pump I can change. In the past I have used hydraulic cylinder stops to help with this issue. 3) When I park the tractor and plow (usually not in the sun) I lower the lift arms and plow to the ground. I unplug the hydraulic fitting from the transport valve without any effort. When attempting to hook it back up (a few days later) there is still an excessive amount of pressure on that hydraulic line on the plow. From what you said, I might have a plugged return? Is there a specific spot I should be looking for this? Is it possible I am not lowering the cylinder all the way, meaning the plow is too far off the ground with the new plow shares I installed? I do notice that the cylinder is not completely retracted even when the plow is on the ground. 4) I have the correct amount of hydraulic fluid in the tractor

The 14 and 45 are not the same animal as far as hydraulic system. Read the manual was so you understood all the adjustments for the 45 system. You seem to act like they are alike and you know all about it. Why then the questions? Everything you ask is answered in the operator's manual.

Why are you lowering the plow to the ground and unplugging the hose ?? I'm guessing the plow settles a little more after a couple of days and then puts pressure on the tail wheel and then you cannot plug the hose back in...……...

The main reason for posting my question was that I have not found the answer in the owners manual. My main question is - why is there an excession amount of pressure on my hydraulic hose on the plow after unhooking? I just couldn't seem to find the answer in the manual.
I have ran the D14 and WD45 for years without issues so this is new to me. The D14 is 100% different and works as normal with all my equipment. I have not yet used this particular snap-coupler plow and I am having a hard time understanding why I get so much pressure on the hose. When you reply "read the manual" that just doesn't seem helpful to me. I enjoy sharing photos and experiences on here with everyone, isn't that the purpose of this message board?
I apologize if this answer is in my owners manual, perhaps I need to read it again to make sure all my adjustments are correct. But from what I have gathered, there might be a plugged return

This might be my problem! What is the best method to lower this plow to the ground? Should I be unhooking the line first, then lower the lift arms until the plow touches the ground? Should I always have the plow suspended in the air so the plow cannot settle?

We pulled the hydraulic clear down to bottom of the quadrant and never unhooked the hose till we’re done plowing.

So,your pressurized hose issue is the problem. What you describe is not normal. Park the shares on some 2x4s for support and see what happens. As Dr allis says,something must be changing/moving after you unhook to put pressure on lift wheel. You are the only one there to see what's happening to figure this out.

My question is, WHY would you want to disconnect the hose anyway?? other than unhooking from the plow altogether for storage. I've never used one of those plows with the hydraulic tail wheel, so I can't offer any help other than unplug the hose only when you intend on separating the tractor from the plow. Place wood under the front and rear plow bottoms and if you have difficulty connecting next season, loosen the hydraulic tip on the hose and slowly bleed off the excess pressure.
