as double07 posted below, rear mounted 3 point brushforks are very common in the orchards here in pacific NW. with the weight on the rear, the traction is where you need it as well as stability. the
photos below are of the brush fork my dad built in 1960s and is still very well used to this day. as you can see, the headboard and tines are all bolted on for when the blade is used for snow and gravel and
dirt or any other tasks during the year. and with the length of the blade frame, the brush can be stacked in decent piles. the previous method of moving tree and cane berry trimmings was tossing onto a flat
bed trailer by hand, driving to edge of orchard or canyon or burnpile, and hand unloading. requiring at least a tractor driver and one or two throwers. at this time, the family was renting approximately
100 acres of nuts. and with trees planted 20 foot square from each other, made for an average of 100 trees per acre. that was alot of hand work every year of clearing out the limbs after the hard job of
tree trimming. Dad says he can not guess how much faster the operation became with the brush fork. Dad said just traveling thru the orchard with a solo tractor instead of tractor and trailer was faster,
and the work completed much faster, and you could start the brush fire and keep feeding the fire with each brush pile instead of tossing in one limb at a time without getting smoke or ash in your eyes.
brush fork is on Ferguson TO30 with sherman 3 speed in overdrive. dad said he was very proud of the outfit and it really worked great. Plus he said it was at a time when most front end loader tractors were
much too tall to fit the the orchards safely, and if they did fit down the rows, they were tippy and dangerous on the the many hillsides.
