My 1971 Pettibone Speed Swing. Its ex-railroad, they had railwheels on them for driving down the track, attachments included railthreaders, grapplehooks(for loading ties), 9 foot wide track cleaning bucket, 3 and 4 yard snow buckets, magnet, brush cutter, tote hook, 20 foot boom extension, clamshell, and many others.
Mine was sold to me with the 1 and a half yard dirt bucket on it, which is fine. I've used it to haul rock, dirt, logs, scrap. I will use it this winter to clear snow. I pulled a 10,000 lb dumptruck out of my back yard with it; lifted the front up like it was a piece of candy.
Its 2 or 4 wheel drive, 3 speed powershift(Allison tranny), front, crab, or 4 wheel steer, has a 4-53 Detroit(2cycle) 112HP diesel, boom raises high enough to load a full size dumptruck, and swings 90 degrees to either side. Power steering too.
I like to work on it. I've changed all the fluids, put muffler brackets on, fabricated my own mirror, rewired almost everything, put a heater in it, one new tire, etc.
The turntable mechanism has the biggest chain and sprocket I have ever seen....
Its a lot of fun to work on and drive. I love it...
