Is there a way to convert a 3pt mower to pull-type (cont

Just a update, I posted this last fall when it was just a idea, and got a lot of good inputs from folks, which motivated me to pursue it. I've backyardED a solution here w/ a 4' mower mated to a '41 JD H.(via a 2 pt mount) There are still a few minor bugs (mostly with the tractor) to work out (including I discovered that the tractor PTO shaft was bent, replacement one otw). As you can see the cross draw-bar wouldn't mount exactly center onto the tractor draw bar, so I took advantage of this and mounted it left-of-center which allowed the mower shaft to be in center alignment with the tractor PTO. I've mowed with it briefly and it works pretty good, the H pulls & drives it well. Any observations/comments welcome. I'm looking forward to using my riding lawn mower this summer. Thanks to those who provided earlier inputs

Nice barnyard engineering, if that is what you want to do. BUT I would not for safety reasons. First, I am not a big fan of fenderless tractors, second, the tractor PTO is unshielded right below the seat and probably most notable is the steep PTO angle making the U joints work overtime. Additionally, It appears that there is no way to lift the mower which would be a royal PITA on my place. And no live PTO. Personally I would use this as an excuse to buy another tractor better suited for the mower. ie live pto & 3pt
 
Good innovation. Going through a dip will cause some the gear box to get much closer to the PTO on the tractor.make sure there is plenty of Telescopic capability in the shaft,and that it is lubed well. Jim
 
Thanks, you are correct. These things were conceived before OSHA. No fenders doesn't bother me (only because I grew up with them, if I found a reasonable set I would buy and install them), I would be afraid of open wheels w/ snow chains (not a problem here). I'm aware of the unshielded PTO, once I have this dialed in, I intend to buy a master shield for it. You have a good eye for the pto joint angle, fortunately I'm mowing only ~1/4 acre of Florida Bahia grass on flat ground (no 40 acre bush hogging thru the hills), I'm using this about 20 min at a time, I'll keep a eye on the U joints and keep em greased. For this small of a application I don't need to lift the mower, I'm otherwise treating it like a pull-implement. The PTO is not live, but I do have a over-running clutch in line (btw, this mower doesn't have much of a flywheel effect so there's minimal propulsion of the tractor when you disengage the clutch w/ the mower engaged ) . You left out one thing, a kill switch, (its on my list). My goal here was to collect a antique tractor (something I was familiar with from back in the day and small enough to justify having it in my residential neighborhood) as well as having dual use as a mower to-boot. Thanks for the feedback!
 

Glad it works for you, but I wouldn't recommend it to anyone. Your ground may be flat and smooth, but I can see trouble if others try to copy your set up. With no top link, if one is going along and the front wheels of the mower drop in a hole, or catch on something, the rear of the mower will flip up before one can react, binding the PTO shaft and bad things will happen fast. A drawbar needs to be rigidly attached to the mower and pinned to the tractor drawbar, not pulled from the 3-point pins to prevent that. Pulling from the 3-point pins, at least find a way to add a top link that allows floating (the connector for the top link that allows that is on your mower) but will limit how far the back of the mower can come up if the front catches. JMHO
 
"Oh that's too much angle on the PTO" and then they'll go out and run their balers or manure spreaders with far more angle than that, and think nothing of it. As long as the PTO shaft on the tractor and mower are fairly parallel most of the time, wear and tear on the universal joints is minimal.

The top link on mowers like these all too often consist of a chain or some other collapsible mechanism so that the mower can follow the contour of the ground instead of scalping. It's a FINISH mower, meant to be used on smooth surfaces, not a rough cut mower or "brush hog."

B E has got it right.
 
Thanks Barnyard! You were part of the inspiration for this. Now that the mower shaft is left-of-center aligned (parallel) with the tractor PTO, the links & turnbuckles generally hold in that position. No hills or wood-chuck holes here.....

oing anything that is not "their way" sure brings out the critics. :roll:

Some people look at a tractor or an implement and immediately think "how safe is that". Those are the people that will probably have the least accidents.

That's because they're the ones who preface their statements with "I would never." You can't have an accident if you don't do anything.

I figure if you grew up operating equipment like this and you can still count to at least 19, safety comes naturally, and you don't need any lecturing. You know enough not to jump off in front of the wheels while mowing. You know to hold on to the steering wheel so something unexpected doesn't throw you out of the seat.
