This is so cool, wished I would of done something like that when I did my mower, but at the time I needed to mow get-err-done thing. Although it held up good just to light, really like this project........Curt

You definitely got lucky on the steel the way the price is going up. I don't think you'll regret the heavier duty. That price makes it a great project. New and way quicker than finding one that may still need work.

...I'm pretty confidant it will work just fine, as I pretty much copied the motor/belt drive setup design from the original. We will see though, I'm waiting for warmer weather so I can get some paint on it. ( Hopefully won't be to much long)

Did you calculate what the RPM will be? If so, what?

Did you calculate what the RPM will be? If so, what?

I'm using the same size diameter pulleys that are used on the original hydra cutter. My Parker motor specs at 1024 rpm. (which is supposed to be the same as the original hydacutter motor that was used) So I don't know what the actual blade tip speed would be. I'm just keeping everything similar to what case/ingersoll used on their cutters. I have a copy of the original hydracutter manual and it states their mower speed is 1028rpm and the blade tip speed of 13,300. Worst case if something isn't right, I will re- gear it with different size pulleys.

I guess we'll find out when you test, but something seems wrong to me. I think you need a high speed motor. What is cu. in. of motor; 8 or 9 maybe?

Finally painted (rust oleum Allis Chalmers orange) and assembled. I still have to make up the hydraulic lines to run the motor and do the first test. So far I'm happy with how things came out. I'm also using my custom made/modified sleeve hitch. It raises and lowers it perfectly in the front and I have the turnbuckle in the rear for height adjustment. I still have the cab on, need to remove it soon. Looks like winter is finally over in the North East! (well hopefully)

Looks great!

BTW... I see these motors go all the way down to 2.2 cu.in. That's a 3.6x speed reduction; plus the belt reduction.

I see the weight inside of the right rim. Do you know what it was originally from? And did you have to modify it to fit over the hub?

Cheers,

Good eye Gordy! I actually found these on eBay. I believe they were weights off of a David Bradly machine. They fit the inside the Case 16'' rim perfectly. I did have to drill 2 new holes in them to mount them, as the original holes didn't line up right to match the holes in the rim. They fit over the tractors hub perfectly with no modification. They weigh around 47lbs each. I also am running the John Deere combines on the outside. There just sandwiched to each other inside the rim. This combination gives me alittle over 200lbs on each wheel and works great! I did not add any liquid ballast in the rear. I also have weights on the front rims. They are off of a Gravley and bolt to the rim. I had to modify them a little so you can access the valve stem They are 15lbs each, and I filled the fronts with washer fluid to give me around 12lbs added weight.

Thanks, I will know more as soon as I test it. I didn't want to get into everything about posting the motor specs yet. I'm expecting it to work fine. I got the motor # from a guy that is an case/ingersoll parts specialist. (thanks Jason if your on here)

Gordy,
Here's a blown up picture of the rear inside weight. You can see where I had to drill new holes in the weight. You can also see how it clears the hub and has a perfect cutout for the valve stem.

If you happen to find part numbers or casting numbers for those, I'd love to add those to the 'what weights fit' spread sheet.

I just went out to get the numbers. Unfortunately I can't make them out. They were pitted and dirty when I bought them, and when I painted these white it really covered them up to where you can't make the numbers out at all. Sorry about that. All I know is the seller I bought them from said they came off of a David Bradley walk behind. They measure roughly 14 1/2'' inches wide outside to outside

If anyone is interested, this looks like the same weights.. I can't see the casting number on these either.

First test was pretty successful! I did have to change my driven pulley out though. I had to drop down to a 5'' to get more rpm out of it. I'm running a 4 1/2'' on the motor and a 5'' on the spindle. It comes out to roughly 1,000 rpms on the spindle calculated. But still not enough weeds or brush yet to actually test it. I did run over some cut up pine branches I had laying around and dead brush and it seemed to mulch up/cut just fine. I will update more once the weeds/brush start to set in.

I'm glad your happy.
Calculations is what I do, I'm kinda a virtual builder. I calculated a month ago that you needed about 1300 rpm for 15,00ft/min tip speed. Maybe switch pulleys to provide speed up, at some point torque will suffer, but until that point, speed is a good thing.
Thankyou for sharing your experience.

Guys
My eyes don't work like that use to so my phone camera works out great getting in those hard to see places
I've used it for serial numbers for awhile that way when I order parts I get the right parts

I know exactly what you mean Dale. My eyes aren't what they use to be, and my ears went south years ago. If it weren't for the cheaters in my welding helmet I would have to give up welding.

Another successful test today with the cutter. Still not alot of brush yet. But I did take it out in the woods and did alittle trail cutting. It worked great!
