DIY/ build along hydraulic Shredder

[HainesNYT]

Building a hydraulic powered shredder/brush hog/mulcher for a skid-steer loader quick connect.

I bought one at an auction that was originally for a high-flow hydraulic machine so I converted it over to standard flow hydraulics and modified it to be a little more aggressive. It has worked well so far. A neighbor asked me to build one to run on his Bobcat 763 which is a smaller, 15gpm machine.

Starting with a used deck...I don't think it was ever actually used...a 60" deck originally for a hydraulic arm/tractor setup ...much like an excavator.

I have about $1000 into parts, plus $450 for the deck. All the parts have been purchased from Surplus Center, online...except for the Connect Under Pressure flatfaced couplers....they were purchased from Baileys Hydraulics

This will have a right angle gearbox that is powered by a hydraulic motor. I'll cover the specs and math formula later.

Omni Gear RC-71 with a 1:1.46 ratio (speed increaser). I wanted a 1:1.93 (two to one) but couldn't even get one custom built.

Tagged. I've got a gehl I would like to check into building a deck for

Gearbox is now where it needs to be...4 holes, 3/4" diameter through 7/8" steel.

Next step is getting the standard AG 6-spline collar to stay in place. I will be drilling a hole through it to place a bolt though it, securing it to the input shaft of the gearbox.

Collar installed. Hydraulic motor will sit here...next step is to build the mount to hold her in place.

[HainesNYT]

Cut a piece of 5/16" plate, 10"x6". Drilled a 3.25" hole in the center for the hub-centric motor. Two 1/2" holes for the mounting bolts.

The plate will get welded to the deck.

That is awesome. I wish I could do work like that. I have been wanting a skid steer with a mulcher or shredder. My wife would die if I rolled up in the driveway with one. It would be a great day.

take you a few pieces of 1/2" square stock and weld on each side of the motor...That way all your torque in not on just the 2 screws....

The "screws" are 1/2" grade 8 bolts. This is my second shredder running one of these motors and I have a third motor in a vibrating drum roller I built...no issues on any of them yet; however, I will look into your idea as the old saying goes "An ounce of prevention is worth a pound of cure". Thanks for the advice!

So here is the formula I have been able to come up with to determine blade tip speed (BTS) in Feet per minute (FPM).

To all of those Who waited with bated breath, I am back at it. Sorry for the delay.

The last piece of the blade carrier is at the machine shop in D'Hanis right now getting the center hole cut in it. I had purchased a 1/2", 4x8 sheet and brought it to a place in Castroville to be cut out on a plasma table. We somehow missed the center, 2.5" hole on the main plate....and I am concerned about the weight and balance so this is the reason the machinist is cutting it out.

The center hub had a pressed fit into the first plate. I welded the inside and ground it down so it fits flush with the next plate. Then I welded 3 more beads on the tops side... Overlapping.





I spent a lot of time waiting for it to cool to prevent it from warping.
