My newest creation has been released on the land or should I say weeds in Billings Montana.

I got this old Haban  mower from Utah Smitty and adapted it to run on hydraulics instead of the front PTO for which it was designed. This was mostly due to my loader getting in the way and the lack of desire to remove the loader to use the mower.

What kind of hydraulic motor does it take to run that? And how in the world do you determine that without playing around with expensive parts??

Looks good there, I cut a lot of hay when I was a kid with a 7' sickle behind our A/C WD-45 mounted on the back.

 

Was that a Haban made for Case mower to begin with?

Nothing I like more than stirring up tractor lovers,

 

To answer a couple questions, I cuts very well and that includes small trees up to 3/4 inch in size and maybe more if I put new blades on her. From what I can tell the mower was made for an older Case tractor and that might have been a 195 but I am not sure. I got the motor from the surplus center and just went with the cheapest one I could find.  I had read that this type of mower has very low horsepower requirements and I believe it too be true as it is easy to spin it with fingers. The fittings are standard o-ring boss at the motor and jic hoses from our local Big-R supply. The motor has a top rpm of about 900 which means 900 strokes per minute as my pullys are both the same size. Somewhere down the road I would like to be able to raise and lower the blade with hydraulics and if anyone knows how to easily set that up I am interested. I suppose I would have to tap my oil lines before the PTO control valve  and that would mean changing the hard lines that feed it. Is there an easier way?

Couldn't you put a valve in the pressure line going to the hyd motor on the sickle bar ? Not sure if you need to stop the bar when raised all the way like on my Tri-Trac the pitman arm binds , if not you might be able to use a regular spool valve and feed the motor on the return . Maybe mount the valve on the sickle bar frame so everything stays together .  I'm sure there are a number of ways ,

Raising and lowering the mower, while also running the hydraulic motor, is actually the first good application I have seen for a special valve.

 

The valve is called a series valve.

 

Multi section control valves are usually plumbed for parallel operation, Yours would be plumbed for series operation,

 

Since neither takes much hydraulic power, the tractor could power both of them without any problem.

 

Finding a series valve might be like finding hens teeth though!!

 

Just something to think about.  :tapping_fingers:

I love your project! I have an old Haban mower made to belly mount on a Simplicity originally. Also have a left over hydraulic drive motor from a 224 I thought about using, but someone told me that would be a bad idea. Can't remember why now. My main concern is getting maintenance parts for the mower, because the best I can tell, the 2" wide sickle sections are obsolete and unavailable. Same with the rock guards. I did find some spare used ones from an old David Bradley implement, so I may try this anyway.

No need for me to lift the bar vertical under power, although this one will operate that way. I just planned to use the sleeve hitch to lift it enough for making turns and such. I don't mind getting off the tractor to raise the bar to transport position.

If I can make this work out, the next project would have to be a hay rake of some sort. I'm thinking a wheel rake, like the little "Estate Rakes" sold by Agri Supply and others. http://www.agrisuppl...-wheel/p/41439/

I doubt if that would handle stuff tall enough for real hay, though. I'll take a look at cutting down a full size wheel rake, too.

Sorry for the thread drift. Back on topic, my Haban would need a pretty thorough restore before being put to work. For that much effort, I think it might be worth going ahead and converting it to 3" guards and sections, which means a whole new cutter bar and increasing the stroke to suit. I'm thinking about actually making hay with this.
