Abstract
ABSTRACT OF THE DISCLOSURE
This tractor winch is characterized by its readily connection to the three-point hitch system and power take-off of a farm tractor and by its simple construction and operation. This tractor winch includes a cable drum driven by the power take-off through a planet gear system with a control brake acting on the ring gear to control the rotation of the cable drum and safety brake to hold the drum against rotation.

Claims
1. A farm tractor winch comprising a housing, a main shaft carried by said housing, a cable paying drum fixed to said main shaft, a planet gear system including a sun gear, a ring gear, planet gears and a planet gear carrier, said planet gear system coaxial with said drum and disposed at one end thereof, said planet carrier fixed to said main shaft and rotatable therewith, the ring gear and the sun gear rotatably mounted on said main shaft, drive means connected to the sun gear and including a right angle gear train having an input arranged to be coupled to the power take-off of a farm tractor; a speed control brake assembly to selectively vary the speed of rotation of the ring gear and consequently of the planet gear carrier and of the drum and a safety brake assembly to brake the drum, said speed control brake assembly including a first annular brake band surrounding said ring gear and pivotally connected to said housing at one end, a manually actuated first arm pivoted to said housing at one end and connected to the other end of said first brake band to apply through the latter a manually controlled variable braking force on said ring gear, said safety brake assembly including a wheel fixed to said main shaft, a second annular brake band surrounding said wheel and pivotally connected to said housing at one end, a manually actuated second arm pivoted to said housing at one end and connected to the other end of said second brake band to apply through the latter a manually controlled variable braking force on said wheel, and connecting elements fixedly secured at three spaced-apart points of the housing to supportingly connect the housing to a three-point hitch system of a farm tractor.
