landscape rake tine distance

[2manyrocks]

I am reading all these posts. The rake I am building is front mounted, like on a bobcat. I am not building any ability to angle the blade. Maybe a mistake but it is beyond my ability, and with a front mounted rake I am not sure of the need.

? My rear tine rake is simply attached to the mount by one pivot point and then a bolt allows you to angle the blade. I think you could do this fairly easily if you wanted.

Or did you mean the ability to angle the blade and tilt it as well? The tilting part I agree would be harder.

Angling.. As it runs off my FEL I can tilt to my hearts content. But I do need to add guage wheels. And thanks for the pic. It is a more advanced version of what I am doing.

But for further explanation. The reason the device shortens to 4 feet is to allow me to attach it to a special kind of boom pole our tractors have. This way I can reach about 12 to 14 feet down a ravine and pull up twigs and blackberries.

Now comes the hard part. How do I build the pivot. Is it just a simple hardened bolt, or should I do some sort of sleaved thingy. I look at everyones build and boy is mine remedial.

Here is a photo of my first build. It failed miserably, but it gives you and idea of what the short version of the rake is going to be used for.

So, I have to build the rake so it comes off the FEL mount reasonably easy and then attaches to the boom pole.

I can only suggest ideas that might be useful.

As for the rake being able to pivot on a horizontal plane, I see it would only be useful in your application for reversing the blade for direction of use. Setting the rake to angle is useful for wind-rowing (moving material like gravel to one side).

What does seem to be almost required is a limited free vertical pivot at the end of the boom because of constant geometry changes during its use. If the rake is mounted rigid, it will want to dig during movement when you only want it to drag.

Also I notice your boom is pinned for maximum lift. Adding some plate allowing the boom to be optionally pinned for more downward curling seems necessary.

As an example, what I visualize is a landscape rake mounted to a Backhoe, curling the debris up.

I also removed every other one, with all the tines on gathered to much of every thing. (see pic)

So, my tractor is 90" wide. If I make an 8' landscape rake, and I pivot it 15 degrees...

It is moments like this I wish I had kids, or had gone into engineering... Actually, I used to know all this math and then... well, if you don't use it you loose it.


Maybe a 9' landscape rake is more appropriate. Woooo that would be a wide piece of equipment...

Oh, and Rhett. Thank you very much for your insight. This rake will indeed spin 180 degrees to fit the front of the PT.. But its mounting will be another custom job..
