Anyone operated a Harley Rake with their tractor

[duffer]

Need to use a Harley Rake to grind up an old driveway. Tractor puts out 9 gpm hydraulic flow. I'm wondering if that's enough to operate a 4'-5' Harley Rake. Most are run by skid steers that have a higher gpm on the hydraulics.

Any of you guys have any success running one with your tractor?

The hydraulic flow you have available is 7.6 GPM. The 9 GPM number is when you combine steering and implement flow which are two different systems.

The harley Rake D4 4' rake requires 8-12 GPM.

What your wanting to do pushes a harley rake at it max, and might not even work unless the driveway is in really bad shape. Your going to need 12 GPM. Another option is to use a PTO powered harley rake. The TM4 requires 15-22 hp and the TM5 requires 18-32 and are on page 11 of the brochure linked above.

That powered rake isn't designed for the abuse you are about to put it through.

Harley rakes work fine on CUT's for their designed purposes...levelling out soil and pushing out roots and rocks. It's designed and meant for reducing hand raking in landscaping jobs, not pulverizing asphalt.

Use your loader to lift up pieces of asphalt slabs for disposal. A grapple would be my goto tool. Rent one of these instead.

Thanx for the links and comments.

Don't have any asphalt to contend with. An old layer of "chip and seal" which is about 1/16" think at this point, and most of it is gone. Driveway has a bunch of ¼"-½" potholes where the chip and seal is gone. Looks like someone dropped a cluster bomb on it.

Had an asphalt contractor tell me he would grind it up with his harley rake, compact it, and then pave it. Only problem is, he's ghosted me for over a month now. So I'm going to Plan B, and wanting to smooth this out somewhat with the Harley rake, regrade it, and then put Crush & Run on it.

Sounds like I'm out of luck on the hydraulic Harley rake. I'll check into a PTO. I've got enough hp to run the PTO version.

Duffer,

Please include picture since an "old driveway" could be anything from asphalt to pea gravel interspersed with grass.

Based on my experience with 6' power ( Harley ) rake powered by PTO on 3 PH on 9000 Lb M59 tractor, I would not be attempting to run a power rake off FEL end of a 37 hp Mahindra for the following reasons. 1 You don't have enough flow at max of 7.6 gpm to operate the drum with sufficient rotational speed to accomplish work. 2 The tractor is too light at 3000-3300 Lbs and would severely bounce around if rake drum hits anything other than sand or soft earth. FEL mounted power rake runs in fixed position and has no option of climbing up and away from a buried bone ( rock, etc) and will cause the entire tractor's front end to dance. Skid loaders and track loaders running power rakes are 2-3x as heavy as your tractor. When I'm running the power rake, weighing 1300 lbs, the rake is hung with chain from upper lift arm on 3PH so the rake can climb out of ground if it encounters a bone it can't dislodge.

Hope this helps.

M59, your comments cement my decision not to even try to run the rake off the FEL. Doubt if I can find a PTO rake to rent but I'm going to try. Don't have any pics, but the chip and seal is made up of bb size pebbles (1/16th" diameter) embedded in hot tar (when applied several years ago). I've actually raised up sq ft pieces with my leaf blower. So a Harley rake should not have any problem.
Crush & run underneath the chip and seal.

If I can't find a PTO rake to rent, I'll take a box blade with the scarifiers, and break up what's left of Chip and seal, then remove the pieces, regrade, and then put down new gravel.

Duffer, A Harley rake will work on breaking up what you have described as chip and seal. You might also look for a 3 PH tiller and run it just deep enough to break surface up. Might be able to find tiller easier than power rake.

ps. I added top n tilt to the M59 and my work output increased 10 fold. Now able to adjust anything hanging off 3 PH with hand controls at my elbow instead of stopping and going back to equipment and cranking the linkage to adjust attack angle. Top n tilt gives me 6 degrees of freedom.

Update:
Couldn't find a PTO Harley Rake to rent. So I used a 6' box blade and put the scarifiers just barely below the cutting blade. Tried it on a small section of the chip & seal drive (or what was left of it) and it worked like a charm. Made 3-4 passes over the entire driveway to get all of the chip and seal remnants loosened and piled up.

Took my 7' landscape (York) rake and raked up the scraps in a wind row in the center of the drive. Scooped everything up into 4 dump trailer loads and took them to my neighbor who had a low spot he wanted fill in. Win-win all around.

Raked the driveway smooth, and now ready for 3-4 loads of Crush & Run. (wanted to pave it, but you can't get a contractor to show up around here. Waited over a month for 2 different ones, and they have both ghosted me) So Crush & Run it is.

This is what I was going to suggest. Box blade with scarifiers. Will prob rip up more than you really wanted to if your not carefull.

Power rakes are more for preparing a seed bed..not removing pot holes.
