I sold my Allis Chalmers 170 tractor but kept the 3 point PTO powered King Kutter rotary bush hog mower. The mower is 72" wide and has the 60 Horse power gear box on top.
When I bought my Mustang MTL25 skid steer I decided I would convert the 3 point PTO mower to attach to the skid steer and be run by a hydraulic motor powered by the skid steer auxiliary hydraulic pressure.
I selected a motor that will deliver the PTO rpm at the working pressure and flow of the skid steer output. I am very pleased with the power of this combination. I was able to mow easily through thick brush that was 6-8 feet tall.
I welded a skid steer universal mounting plate on in such a way that the mower can be lifted up and used to trim trees as I drive under them.
I took my old 3 point bush hog and converted it to run on my skid steer. This is just the first run around my firewood lot after the conversion. I will post more mowing videos as the jobs come up.
Used a Char-Lynn Series 2000 motor that gives 525 RPM at 20 gallons per minute of fluid flow. The motor has a built in crossover pressure relief so I did not have to add a check valve for shutdown ease. My MTL25 skid steer puts out 23 gpm at 3000 psi. That means the hydraulic motor produces about 39 HP minus losses in the motor and gearbox. It has lots of power. Plus I can raise it up and trim trees and hillsides or tilt down into pond banks. I did raise it up and mow some low hanging branches and it worked well. I used 1' of cutter width should have 5 hp formula to see if my machine would run the 6 ' wide mower. I seems to be a good formula because I have plenty of power as you can see in the video. Those weeds are 7' - 8' tall and pretty dense and I could mow them at a good speed without trouble. I was mowing in a weird pattern because there was lots of firewood hidden in the weeds that I did not want to hit with the mower or run up on with the skid steer.
I love this thing.
The coupler is a 1" to PTO adapter. Local tractor store had them for $12.00
I sold my Allis-Chalmers 170 tractor that I used this King Kutter mower on. When I bought the MTL25 skid steer I decided to convert the mower to run on hydraulics and attach to the skid steer. The mower is 72" wide and has a 60hp gear box. I unbolted the gear box and turned it 180 degrees and rebolted it. I could have left the gearbox in the factory position but decided that since I was mounting the attachment plate on the back I would go ahead and turn it around to keep the motor out of harms way better. Then I made a mount for the hydraulic motor to bolt up to. Bought a universal attach plate and welded it on with some braces. I don't understand why these sell for $3,500.00 - and up when the PTO units sell for $1,000.00 and up. I paid $1,100.00 for the 72" mower with the 60 hp gearbox new as a PTO unit. Then I bought a universal attachment plate for $125.00, and the hydraulic motor for $325.00 including shipping and $12.00 for the coupler. If I count my labor and bracing steel in as well I would have around $1,800.00 in it.
I found this skid steer on craigslist for $9,000.00. It had a bad travel motor and the guy selling it did not know what to do. A new travel motor was nearly $7,000.00. I bought the skid steer and after a couple weeks of searching found a used travel from a Takeuchi TL150 skid steer for $3400.00 delivered. Sweet!!! Took about 4 hours to install the new travel motor and reinstall the track and off it went.
It has a 100 hp Yanmar 4 cylinder diesel engine. Working load of 3500 and a tipping load of 7000. I have picked an old station wagon with the grapple and carried it around before. This skid steer likes to work hard and lift heavy loads.
The tracks on this skid steer are 18" wide and weigh 600 pounds each just for the rubber track.
This skid steer is an absolute beast and a blast to operate. I love it. It has joy stick controls. The left stick controls travel forward, backward and side to side. The right stick controls the boom raise, lower, and tilt up and tilt down.
It is a 2 speed travel skid steer. There is a button on the joystick that you press to select hi or low speed.
So far the attachments I have are the 84" dirt bucket, the heavy duty 80" rock grapple, pallet forks, and a 72" bush hog that I converted from 3 point PTO to universal quick attach with a hydraulic motor drive.
Whatever job I need to do with this skid steer whether it is mowing, plowing snow, brush cutting, moving pallets of firewood, etc. it has the power to get it done.
It is the same machine as the Gehl CTL80 and the Takeuchi TL150. In fact the used replacement travel motor that I bought to repair it came from a Takeuchi TL150 skid steer.
Everyone should own one
