Skidding winch - need bigger tractor?

[Dead Horse]

rbargeron, takes a big man to do that...............

you ok in my book, son!


and that tractor clutch is fooked!


Also, FWIW, I can understand the winch jerking a tractor around some, specially with a hang up. How some ever, some basic fundamental rules apply!

First, your lanyard needs to be long enough such that you are well off to the side of your tractor when winching.

Second, watch the cable as it feeds into the top of the winch, NOT the log. You will be able to respond much faster with clutch control if you keep your eyes trained on the winch head.

Third, If you have "raised up" or nearly tipped over" your tractor while winching, you have NOT set the winch up properly. It will NOT do that, CANNOT do that if set up properly. The physics are all wrong.

Pull straight back (90 degrees) from the winch frame. Use a block if you cannot get the tractor angle right.

Larger farmi's have a movable pully mounted lower on the frame which significantly changes the direction of force, basically driving the winch frame into the ground. It is there for a purpose..... using it results in the force being applied to pulling on the lower links and pushing on the top link, rather than pulling on the top link, using the lower links and feet of the winch frame as a fulcrum..

Picture of said pully on a farmi 601, it is mjust below the farmi name. It is movable with pin holes on the center spine of the winch frame. The heavier the pull, the lower you mount the pully.

It is important to be sure you have a robust top link, in any case, wether tension or compression forces are at work.

Words to live by - especially the lanyad thing.

I'm way too old to be your son. BTW that 601 looks like one I traded to a guy in upstate NY a few years ago. It would lift a 90hp Deutz. Take care, Dick B

Could be the same one!. I bought it from a guy near lake Placid. It needed a complete rebuild but that was about $150 bucks in bearings. It pulls like a locomotive, now.........

And set up right, it will NOT lift a Hesston 100hp, even with the FEL dismounted. Wit a heavy pull you use the down pully and the physics will not allow it to do that. The leverage is just all wrong. Plus, I run the trqactor at 1000 RPMs. There is absoutely ZERO need to run the tractor RPMs any higher than peak torque. On that Hesston, peak torque is 1500 RPMs, and I have not needed it, even with a pull of three very large beech trees up a steep slope.

Like I have advised...... it is ALL in technique.

and "son" is a term of endearment. Sorry it didn't sit right with ya.

I just got schooled in winchology - read the thread with Bob Mayer's comments. Cut & pasted that to a Word doc for future reference. Thanks for pointing me to that golden nugget, rbargeron. Also enjoyed all the learnin' from this thread - it motivated me to pull the WSM and study how the PTO driveline and clutch are configured. I don't have a winch, yet, but some day ... some day ...

the guy I bought it from said it lifted his Deutz, maybe he was using the top pulley.........other identifying features: the plow edge had a gentle convex bend, and the shroud on the lower pulley was bent out. I pulled some big softwood logs - then a friend used it a few months before I traded it for a snow blower.

Jim, Bob Mayer knows his stuff - he's is a consulting forester in Indiana who I believe advises state agencies and land owners, small and big.

Likely the same unit. I fixed the lower pully shroud, replaced the PTO shaft (which was junk) and put new input shaft and thrust bearings in it. I was happy with the price I paid for it, but had I known how bad the bearings were in it, I would have perhaps looked for a better price. When they let go, what was left had obviously had a tough last few years.

It turns out that replacing the bearings in these units is not really a hard job at all. The toughest part is removing the spool with a whole coil of cable on it....... putting it back on takes a bit of technique too.

You have any idea how old it is?

Like I posted earlier, with the new bearing in it, it pulls like a locomotive. Using the lower snatch block properly, it just tries to dig the dozer blade in deeper. Me and my hired hand did several up hill pulls with it yesterday..... big honking beech and a heavy old poplar that was about to blow over.

Last fall, before I rebuilt it, I pulled a 60 foot poplar up a steep rocky bank. The butt of the tree was 26 inches across. I just split that old sucker up this afternoon. Man, that is junk fire wood, but hey, it was down. No point in wasting it.

The bearings finally gave out a few weeks ago when I pulled a big Deere loader out of the mud. I guess 25,000# was just a tad too much for the old bearings! Ha! I got the loader out, though and did not stand my tractor up!

You can very easily double (or more) the pulling power of any winch by the technique used to attach the pull cable.

If the winch cable runs out to the load (tree) and is attached directly to the load, then the pull (winch) capability is direct (single).

If the winch cable runs out to a block attached to the tree, and returns to the tractor for attachment, then the pull capability of the winch is doubled.

I've seen several advertisements for log skid winches that sell as a part of the winch a block and cable for attachment of the block to the tree for exactly this purpose.

Of course, you're going to get only half the cable length using this method. If you need a longer run for a difficult tree location, consider a separate extension cable that attaches to the tree, and runs back towards the tractor, and attach the block to the end of the extension cable.

Hope that helps.

................You have any idea how old it is?..................

No idea about age - Farmi could probably tell from the S/N. We posted about this winch back when you were buying it. Sorry you got stuck with failed bearings. The rest of us owners apparently used them up. Still $150 isn't bad considering what this unit will do. Take care, Dick B

I have seen a picture of a differential case on a Kubota torn in half by a 3-point mounted skidding winch. The top link mount ripped right off the tractor, taking half the casting with it. As I remember, it was an L4830. More horsepower may not be your solution.

Makes me wonder if a spring cushioned top link would help. I know when I pull the cable out to hook up a log with mine, it pulls much easier by unhooking from the bottom pulley. It's really easy to forget to hook it back to the bottom pulley, which will raise the front wheels of ttactor up & put some serious stress on the 3rd link.

I have gotten in the habit of putting the pull rope somewhere on the lower pulley so that I have to visually see the pulley not hooked up to the cable before I get ready to do a pull. It helps.
