Self Propelled Rock Picker
"It'll pick up rocks ranging from fist size to 800 lbs., says Minnesota farmer Wayne Juhl, of Greenbush, who built his own self-propelled, hydrostatic-drive rock picker from scratch.
"I built it because I wanted a faster machine than the pull-types which are clumsy and leave a lot of tracks in the field. I like the hydrostatic drive for its instant forward and reverse range of speed selection - from zero to eight miles per hour - and because there's no clutch to wear out," Juhl explains.
The rig has power steering and planetary wheel drive. Tines on the 3-ft. wide front loader are spaced 4-in. apart.
The loader bucket dumps rocks into the hopper, made from 5/8-in. thick oil pipeline. Rocks are then dumped from the hopper into the desired spot.
The 3-wheeled rig has a 56-hp Isuzu diesel engine and a 30-gal. hydraulic reservoir. The front wheels (15L-16 tires) were purchased new and put on a front axle from a 2-ton truck. The rear wheel (18 by 36 tire) is off a combine.
Juhl says it cost about $10,000 to build the picker. He's used it more than 2,000 hours with very few repairs.
