Mowing Side Mower

[stray]

I am starting to build a side mower. I believe this will be the hardest project I have taken on yet. It will most likely be 2 or 3 weeks before finishing. I will post more pics as progress permits but for now does anyone recognize this deck?

Looks like a Snapper deck.

Are you going to put an engine or a hydraulic motor on it?

 

[stray]

Yes that is right JJ it’s a 28" snapper deck. I am of course going to us a hydraulic motor and build it somewhat like Power tracs. There are so many advantages in making it hydraulic. The motor is a .7 cc. I hope I have calculated right!

On to the mower project...

Looks very interesting. I noticed a pickup tube on the deck. What are your intened uses for this mower? I see leaf pickup as a possibility. /forums/images/graemlins/wink.gif

Thanks Moss, didn't know that, corrections made. I have lots of uses for the side mower. Pond banks and road ditches are the main ones. I hope to get this mower to blow grass out and away form the water to be picked up later with the yard sweeper. Of course the pickup can be removed and caped if not needed.

I would like to find a true off set mower.
The mowers everybody calls off set are really just regular mowers that track in an over lapping path of the towing tractor.
The common characteristic of all tow behind mowers including the so called off set ones is that they al cut only between the wheels whereas a true off set mower would mow outside the wheels.
To me a true off set mower would be a mower that cuts well beyond the path it follows if you get my drift.

 

[MossRoad]

Do you mean you would want a mower that would cut, say, a 5' path, but the wheels would only be 4' apart, so that the cut overlaps the wheel tracks by six inches or so?

I would just match your pump output to a hydraulic motor, seems like it would be larger that .7cc. You don't want to much pump , and not enough motor, or the relief valves would be bypassing. I believe that your pto output is solenoid control, and therefore you have full output at all times, where as mine, has a handle control, which I can control the hyd flow. The blades for this deck would normally turn about 1600 to about 2500 rpm. I have used the Snapper decks before, and they will suck the dirt right out of the ground with that rounded deck.

I found this one that someone on TBN had built for their 3PH. It uses a 2 cycle motor.

Just look on PT web site. http://power-trac.com/ Look in attachments.

So what you are looking for is something like this? (A standard power trac attachment) Note the nice hefty couterweight... imaging mowing on the side of a slope with this baby without the counterweight...

Or maybe you mean something like this? (another standard attachment)

I was overwhelmed with the "toys" I saw at Power-tract last week....and these pics are just a tease. Ya know your in a different world when the first person you meet is called "Bubba" and really looks like one...LOL. These guys know how to make nasty toys.

According to my calculations the .7 cc at 8gpm should turn the 28" blade the same speed that a new snapper 28" lawn mower blade turns. I did this because I really want to blow the grass up and away from the pond. I started out wanting to use a larger motor but the figures said .7 cc. I’ll just have to wait till I get the mower finished to see if it does what I expect it to do.
Does any one know what size motor is on Power tracs 48 or 60" finish mower?

------------------
Wonder if it could be adapted to work on another tractor?

 

[J_J]

This is what I found at Surplus Hydraulics tech help

8 gpm at .77 cu in hyd motor=2400 rpm

Torque at 2500 psi .77cu in =306 in lbs

Is that enough torque? That's only inch lbs

Something like that but the ditch I need to keep trimmed is 2 or 3 feet wide so I would require a good bit more that a 6 inch overhang.

Some one said power-trac.
Has a boom mower for $1700 which hain't bad considering that's in the same price range as a MMM.
Trouble is I don't have a power trac to use it on.
To bad it can't be rigged up on other tractors.

The one Tim has pictured is PT's. It has a 20 inch cut. I did a little more on my 28" last night. Here's a pic.

There is no reason that it can not fit on the 3PH with a little adaptation, if you have adequate hyd supply.
