Newest addition to my family of tractor implements

My apologies and thanks all in one

I apologize to everyone who was confused by my multiple threads. This is my first time working and reporting on an on-going project. This fact accounts for two of the threads. worse, each time I tried to attach pictures, I failed to get them attached properly so I started a new thread to get the pictures out there. This doubled my threads. I was not trying to be rude, I was just an little inexperienced.

I am, however, going to attach some pictures of my most recent modifications. I substantially redesigned the toplinK connector and I think it is much more secure now that previously. I added a lot of metal strapping to keep everything in place. I also added angle bracing--thanks to all who recommended this--and now all I need to do is to attach the link pins on the lower arms. My plan for this is simply to measure VERY carefully and bore a hole to allow the link ping to fit in. This hole will be drilled from the inside to allow for the rather large nut that attaches to the link-pin. I bought an extra long link pin (extra threading) to ease the drilling. I want to make certain that the pins are perfectly square and even with one-another.

Anyway, here are my most recent modifications. It should look considerably better than it did on the last post. As always, I welcome any insights that I overlooked, missed or just plain forgot.

Thanks in advance,

Thank you everyone for putting up with my multiple threads. I hope to do things right this time.

I finished my prototype yesterday and gave it a whirl. Unfortunately, those of you who commented on racking forces were more accurate than you may have realized. The simple act of raising up the rake pulled the 3pt connector back a good deal so I quickly lowered it, made some quick re-adjustments, added some more metal, and most importantly, I added a 4x4 connector from the upper top link to the 4x4 that houses the tines. While I still have some more modifications to make, this was satisfactory for the moment.

I then went out to the field, dropped the rake--and actually raked up a small windrow! Not quite mission accomplished, but at least enough to know that the concept works. With more attempts I heard something horribly frightening--a screeching/cracking sound! At first I thought I was pulling apart my 4x4's, and if those don't work, nothing wooded will (foor any reasonable price that is)! Turns our the sound was a much more benign issue. The tines, which are held in place by steel piping, were rotating to face slightly backwards. I noticed that the pile I was raking was not growing quickly and I needed more downpressure which exacerbated the tine issue. While building, I thought these were so tight that nothing could move them, but apparently a few inches of loose grass will do it.

This morning, after taking out the trash, I restored the tine issue. I found a nice, flat spot, droped the rake solidly into the ground, and gently backed up in low gear. At first, nothing, the tines bent as they are meant to. But after several inches of backwards movement, the screech returned and I looked down and was pleased to find that the tines now angle forward about 20 degrees. I gave a few more pushes back to even out the tines and then returned home. I plan on modifying to see if I can maintain this configuration.

I attached a couple pictures to show the current configuration--it will be modified again shortly.

Wow, lots of work there and enjoyed all the pics.

About the weight, don't think you need very much weight just the right bending action. The pine straw rake I posted before weighs about 75 lbs for the 6' model. For normal raking of grass, leaves and pine needles this is all I need. When I use the psr to cover seeds that I broadcast or for dethatching I add two 42lb front weights to the frame, this doubles the weight and makes the raking slightly more agressive.

Work, Yes. Fun, yes. opportunity to use power tools--definitely worth it. Plus, it was cheaper than most alternatives.

Jenkinsph,

No, I have no plan on adding any weight to it as its wooden construction is plenty heavy. On the other hand, I do plan on removing the center 4x4 angle support and replacing it with a metal counterpart, perhaps even a cat0 toplink. This would allow me to dial in the perfect amount of strength to the vertical support. I do plan on adding some metal strap support underneath the tines. If you look closely, you can see that the tine support is arranged in such a manner that a metal strap could easily connect to the 4x4. I also plan on slipping some 2x2's into the space between the top of the springs and the 4x4. This would help prevent the springs from rotating backwards. I may even lower the hight of the toplink to make overall attachment easier to manage. Right now, the toplink is dangerously close to its maximum upper limit. Please let me know what you think, and thanks for the comments as always

SI2305,
You are obviously a craftsman,handyman. I've woodworked for over 40 years and have done as you,used wood when metal would've been so much better. About 10 years ago, I finally taught myself how to weld. It has been alot of fun and there is so much more I can do,and easier,stronger,more durable now. I would venture to guess,it wouldnt take you very long at all,to learn welding.... Especially with the excellent videos,etc. on the web. This project would've taken a whole lot less time using metal,been stronger and more durable.(unfortunately ,that wood is going to move around with temp/humidity and loosen all your fasteners) Thanks for the posts and pictures.

Hizoot,

Thank you for your very kind comments--I don't know if I would be that kind myself. Mostly I learned from watching my father who was a general all purpose do-it-yourself-man, whethere it was carpentry, fine woodwork, electronics, home electrical wiring or computer hardware or software repair/build/modification.

Personally, I have been woodworking for about 20 years now, and the longer I have had my tractor, the more uses and "needs" I have found for it--most recently obviously being a rake.

You are not the first person who has suggested that I take up welding, but you are the first person I have not known to reccomend it. This has making me take this more seriously. My main impediments are that I will need a whole new set of tools (but that is not so bad either) and the price of metal seems sky-high right now. One of the main reasons I chose wood (I briefly considered metal and attaching with bolts, but the metal pieces I could find were terribly expensive) was price. Wood is dirt cheap right now--I suspect because of the housing turdown. This low price, the various pieces of perfectly good treated lumber laying around in my garage (leftovers from previous projects) and my general skill set made wooden construction the obvious choice, despite its various drawbacks.

On a related note, the metal connectors--strapping and 90 degree braces--have by now become the most expensive part of the build. The steel spring teeth were heavy duty, numerous about $50 alltogether--and made in China. My understanding is that the Chinese government's manipulation of the yuon has made virtually all imported metal so cheap that no American manufacturing can compete. This does not seem to be the case with general steel pieces. Am I correct in assuming that these metal pieces are made in America and therefore more expensive than steel manufactured in China? Are steel prices actually as high now as I am percieving? The thought of building with metal is VERY intriguing, but the cost might be prohibitive.

Again, thanks for your generous comment, and I look forward to any insights you may have.

P.S. I intend to send some pictures of the rake in action or at least showing the results of it being in action.

One thing to consider in a build of this type is getting hold of scrap steel instead of buying new. I have bought some steel lately and yes it is high. But often you can go to the junkyard and with a bit of scrounging find good scrap for a low price. Sometimes individuals have good scrap lying around they might even give you. Like you I used to work in wood only as I did not have a welder and if it could not be put together with fasteners then I did not put it together. Also consider that with metal without a welder you cannot put back any metal you take off. but with a welder you can put metal on metal, grind it off to shape it and put in back on again until you are happy with it. Sure it does require some investment and when I bought my first welder, the wife and I scrimped and saved for it for some time as we did not have a lot ofmoney extra then. It was just a Lincoln buzzbox AC welder but I got my moneys worth out of it repairing things in short order. I still have it, although I never use it now since I got my DC welder. Some have had luck finding a good used AC welder for around $125 or so. A stick welder is very economical to run and very versatile. I applaud you for taking on this project.

Looks like it is ready for a test run. When is that planned so we can see the accomplishment in action?

Thanks to the admin for working these threads into one.

 

[SI2305]

Did a very preliminary run yesterday and did a few quick modifications. It should be ready for a real run today with photo opportunities. I did take a few pics of the site after being racked and while it generally did a good job, it was a cloudy day and the pics turned out very mediocre. You could hardly tell the raked from non-raked areas. Today is bright and sunny and I think I can get some better pics.

I will say that even with only a few preliminary passes, I raked up far more in 15 minutes than I would have in a day previously with a hand rake.

more to come.
