Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage, but nowadays a great variety of tasks. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised. ==== Challenges ==== ==== To do ==== {{:archive:worm_gear-nmrv050-10_15_.jpg?600}} * Purchase 3x gearboxes, motors, spindle kits * Purchase 4x linear actuators * Purchase 8x mounting pins for linear actuators * Purchase truck box * Purchase 2x rear casters * Draw / cut gearbox mounting plate * Draw / cut linear actuator mounting plate * Draw / cut arm pivot plate * Draw / cut caster mounting plate ==== Approaches ==== ==== Light duty electric ==== * [[https://www.ebay.com/itm/361206558529?epid=7033529401&hash=item541996af41:g:yZoAAOSwj49i3aD-|MRV050 or NMRV050]] worm gear reducer * [[https://www.ebay.com/itm/201139009344?epid=7007851850&hash=item2ed4d1b740:g:ACgAAOSwyt5i3aEA|MRV050 Worm Gear Speed Reducer 1" Keyed Single Output Shaft Kit]] * [[https://www.amazon.com/dp/B072MSWVK6/|PROGRESSIVE AUTOMATIONS 12V High Force (3000 lbs) Linear Electric Actuator PA-13]] * [[https://www.amazon.com/PROGRESSIVE-AUTOMATIONS-Industrial-Linear-Actuator/dp/B006P58Y6G/|PROGRESSIVE AUTOMATIONS Industrial Linear Actuator Stroke Size 12", Force 2000 lbs PA-17]] * Gearbox mounting plate x 2 * Linear actuator mounting plate x 4 per actuator * Arm pivot plate x 4 (can include linear actuator mounts) * [[https://www.amazon.com/gp/product/B08GKRYX6F/|Hoist Crane Remote Control Wireless F24-60 12V]] * [[https://www.tractorsupply.com/tsc/product/titan-casters-12-in-pneumatic-plate-caster-swivel-450-lb-capacity|12 in. 450 lb.
