Rake Harley rakes - why so much?

[_RaT_]

MLB, my understanding is that the T models only have one hydraulic function which is the angle adjustment for windrowing. That is something that is in someways to its favor. Mine has a set of solenoids that divert flow via a switch mounted on my tractor. Position one with no power at the solenoids defaults to the roller hydraulics allowing you to lift the roller assembly right off the ground if needed. The second would be the angle (windrowing) function and the third being the lowering/lifting the scarifiers. The amount of work this thing saves you is unbelievable. Sometimes what would appear overwhelming for even the Harley is quickly resolved in one pass. It's almost like magic. I'm not trying to sell you one, but let you know just how helpful mine has been. Should I get it hooked up again, I'll snap some pictures. Rat...

WOW! thanks for the pictures. I've been considering a Harley Rake for some time but you just convinced me!

A few Questions.

I see the T6 requires 22 to 35 horsepower. The T8 35 to 70 hp. Is this Engine HP or PTO HP?

Would a L3134 with 35 engine HP and 27 PTO hp run a T8?

Doing primarily residential, what would you guys recommend? the T6 or T8?

Mike, I will certainly let Derek answer this question more accurately. My Pro 8 is over 1500lbs. My L3830 HST handles it easily with the loader on for counter balance. I find the PTO HP is really not the issue as the rake really does not load up the engine like say a mower. If I were getting a rake, I might be opting for the T-6 but would really want to give the T-8 a look. I think the HP range may well have more to do with getting a tractor size weight established rather then getting a PTO HP to operate it. MY L3830 does not even know when the rake is loading up, the clutch will slip well before the engines RPM diminishes much. It handles the pulling of the rake very well. HST works exceptionally well with the Pro 8.

When I was looking at the Harley I had phone conversations often with Glenmac corp. The HP listed are for tractor hp not pto hp. As Rat mentioned this is more of a gauge of tractor size than hp. There has been 2 times where I lost power during raking. It was wet material, material was compacted with grasses, the roller was 6" to 8" below ground, with endplates installed there was a huge amount of material being pulled. This only happen twice the first time by accident, the second time for fun /forums/images/graemlins/smile.gif. I have never seen a pro series other than in pictures but I would think the T series would require just a touch more hp than the pro series due to the carbide roller. In my posted pictures in this thread I never ran out of power, my rpms dropped a few hunderd rpms once or twice. As for residential work I would go with the T-6. You can get into much tighter spaces. The only reason I went with a T-8 is I needed to cover my tire tracks. As far as quality between the T-8 and T-6 exactly the same.

Light bulb on (maybe)--Power rake turns which way?

I've read all these posts and just figured the power rake turns like a conventional roto-tiller--but duh, if it rakes rocks, it has to turn to toss the rocks forward and down the row of teeth to get to the end, right?

So how much dust does it kick up tossing all that stuff forward???????? Ever get any richochets off the tractor????

Thanks,

Re: Light bulb on (maybe)--Power rake turns which way?

It probably does not turn as fast as a tiller, especially if you consider tip speed. If its dry dirt, its very dusty. The rocks do not fly out from the roller which spins forward to kick the rocks continually forward. The rocks in fact don't really fly out at all. If I'm grading, I like to build up a little pile of fill material in front of the rake. That has two benefits. It gives you supply to fill the low spots and it also quiets the rocks when your in an area with tons of them. Rat...

Re: Light bulb on (maybe)--Power rake turns which way?

I hate to dumb down this thread, but here's my stupid question - does the roller just kick rocks and clumps to the side or are you actually "pulverizing" what goes through the rollers? I've only seen these working at a distance.
Thanks for the pics - they were perfect! Convinced my wife we should rent one of these in the spring. The going rate for rental here is $100 / day $300/ week. I'm thinking of getting it for a week and trying to set up some jobs to make some money back.
WISH I could be looking to buy one! /forums/images/graemlins/frown.gif

Re: Light bulb on (maybe)--Power rake turns which way?

The Harley rake will pretty much crush any dirt clods. Rocks or concrete will be kicked forward and eventually off to one side or the other. The Pro 8 has one extra feature and that is a set of spring tooth harrow type rack on front hydraulically mounted to open the soil up. It works very well.

I just got my info from ATI on their rake. The video arrived a couple of days ago. Oddly, the rake looks very well built and designed but quite frankly, doesn't appear to do as good or any better job then the Harley. It's cost is significantly more I think if the web prices are correct. It's a very well built unit.

Thanks Rat, I thought I was losing it. Keep seeing references to scarifiers but don't see any in the video or print ads. Why would they have them on the skid models and not tractors?????? /forums/images/graemlins/confused.gif

Mine is called the Pro 8, the original Glenmac/Harley design. It is a 3 pt set up for a regular tractor. The T series like Derek has with its carbide teeth would not need the spring tooth assembly as much. That plus trying to keep the cost down by not only introducing another componet but also the electric diverter valves and other hydraulic componets would be my guess. Rat...
