3-Point Hitch 3 point lift--how does it work???

[TractorLegend]

After getting a new rear blade mentioned in another post and coupled with the fact I have a sore neck from crooning around to the rear using it- I got to wondering:
>>>>>>> how does the rear 3 point lift work? <<<<<<
I doesn't appear hydraulic as the arms come out of the sides of the rear end...
plus the controls don't quite work the same as the loader and other hydraulic type controls, its sort of finnicky trying to use it to blade a driveway.

Would a tip and tilt rig help an aging soul??

There is one hydraulic cylinder inside the transmission housing under your seat. It attaches to the rockshaft that moves the outside arms.

Top n Tilt would be quite helpful. 3PH control isn't very fine, as you have found out. You can also change the effect of your rear blade based on which top link hole you use. The 3 holes give you more or less cutting angle. Me, I want TnT! You can also adjust angle using the right 3 pt. arm level adjust crank.

Yes it is hydraulic. A BIG piston that turns the rockshaft that lifts the arms. The lever on mine (JD) lifts arms to the selected point. Then there is a weird option of draft control (wish I Had). Making it even stranger acting.

The three point hitch has no down presure, just lift. Seems to me that I saw another post about grading with a rear blade. It's pretty easy if you put adjustable gage wheels on your blade, also when using the gage wheels you can adjust the top link to fine tune the cut. Out for less and in for more. Will try and get some pics of my grading tools in here. I also turn the blade around and lower the casters to keep the blade just off the ground for plowing snow so as not to plow off all the gravel. Good luck.

Now don't laugh.....


Under a really heavy load, can the 3-point piston come up through the bottom of the seat?

Sorry but I had to laugh That could hurt

No the piston doesn't have enough travel to come up thru the seat. Most tractors also have a relief system that trips when the piston reaches a pre- determined point, and stops the travel before the piston comes out of the cylinder.

No. I have a link with much info and pictures that shows a typical lift stem including the piston, lift cylinder and how it rotates the rock shaft

Don't worry about your backside if the 3pt cylinder lets lose. I rebuilt the 3pt hydraulic pump and installed a new pressure relief valve on a 8n Ford I have and now I could really lift things. It worked good. So good, that the original 50 year old cylinder let lose with the end of the cylinder being completely blown off. It does wake you up. Sounds like a shotgun going off right under you. As mentioned, the piston has limited travel and with all the steel of the tractor case, your backside will be safe. No hospital visit required. Just a little, ah ****, and some more parts and work required.

does that model have draft controls too? If so, this could be an issue for you. It must have taken me a week to figure out the draft and position controls on my tractor (the manual was sooooo helpful), and I'm sure I still don't have it right (by the gouge I left in my drive last snowfall). I found the rear blade to be really effective (without gauge wheels) when it is pulled and drags dirt with it. Other than that, my lack of skill or knowledge has lead me to believe that it was wasted money, other than for pulling dirt. I didn't care for it's snow removal qualities, because it overflowed with snow quickly.

Just my opinion, and I am not a tractor guru by any stretch of the imagination.

I'm thinking that my uncle's advice is as true for tractor attachments as it was for wood working tools. Although a tool may serve multiple purposes and do okay at them, it will never be as good as one designed for only one purpose. e.g. rear blade - snow plow.

I have a J D 3203. I lift the 3 point with the hydraulics. I let go of handle and it goes forward and 3 point goes down as well. Do I adjust linkage, open or close valve under seat or go to tractor repair shop. Thank you. Gratz

 

[roadhunter]

I always had the same question. Somebody tried to tell me that some of the smaller CUT's have a different system like worm drive that controls the 3 point. I had a problem with my Bobcat tractor's 3 point and had no idea how it really worked inside.

My JCB has a external cylinder on the 3 point.

This may help.

I'm not personally familiar with that tractor. You might start a thread in the John Deere Owner/Operator forum and pose your question.

Regardless of whether it's "Position Control" or "1/4" 3pt or any other version that I know of, when you release the handle the 3pt should stop moving. I'm guessing yours is out of adjustment.

Again, pose this question in the John Deere section and someone will educate us both.

There are instructions in the Deere forum. I have a 4200 and had the same problem. Instructions were very helpful and was an easy fix. Have to lift the seat and possibly remove a cover.
