WD45 rear hydraulics struggling

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

My main tractor has been in the shop half the summer, so I picked up an older WD45 so I could keep up with my work of moving bales to horses and keeping the fields topped with the brush-hog.  She purrs like a kitten and seemed to be exactly what I needed.  I tested everything out that I knew of (I'm pretty much a tractor beginner), including raising and lowering the rear hydraulics.  

Then I got it home.  And I can't get the darn thing up.  At first I made the mistake of trying to make it move while my foot clutch was engaged.  THen I remembered I need to let the foot clutch out, so I did so, but no luck.  Now it will come up very, very slowly, and then once it is up, it will come down. But it won't lift anything. 

So now I have two broken tractors and am falling way behind in my work.  Hoping someone here can give this rookie a quick solution.  Thanks

	Is it adjusted for "Hold Position?"

	How is the oil level? Check it on left side near battery box.

	Totally agree. The main two reasons I encountered issues were either low hydralic oil level or the adjustment screw not properly adjusted. Otherwise the WD hydralic lift is awesome. Good luck!

	I did find the hydraulic level low, despite the seller assuring me he topped everything off and he did a fresh service. After that, I was able to get the back to lift a brush hog, but it took about 30 seconds for the lift and I had to increase the throttle pretty high to get it to move at all. I am going to read the manual regarding the "ADJUSTMENT" mentioned above. Thanks. Now I have to figure out why the PTO shaft on the brush hog won't seat on the tractor's spindle. Another thing I notice is that this configuration on this tractor jams the implement right up to the tractor. I suppose they make longer arms?

	Hmmm... Is there a sliding thumb key you have to press to get the PTO to engage on the tractor (and that will lock it in place)? My hydraulics will run out if I have to donate fluid to a ram or something. Usually remote cylinder operations require the most proper fill level. Wouldn't surprise me if hydraulic fluid runs out or spills into another compartment in the tractor. You may have the cultivator "delayed lift" setting configured? But 30 seconds seems very long...

	Dad had something like this happen once when trying to lift the mounted disk. He eventually discovered one of the lift arm cylinders was reversed like you would do for the front mount cultivator.

	So it turns out that the extension spline, which I guess is really a slip clutch of sorts, was slightly twisted. It was barely perceptible, but we have gotten another and will install it today. I did find an Allis Chalmers restoration expert, and he's coming tomorrow afternoon to pay a visit to work on the hydraulics.
