Mini bulldozer plans include making a dozer from a garden tractor and making one from an old lawnmower. Some plans are free online and some companies, such as Ubuilditplans.com, charge for plans.
Ubuilditplans.com has a variety of mini bulldozer plans for sale. If built to the specifications listed in the plans, a mini bulldozer from Ubuilditplans.com can smooth rough terrain, easily push dirt, snow, rocks and brush out of the way, pull small tree stumps out of the ground and skid logs. Each plan comes with reference photos and a list of necessary supplies, down to the smallest nuts and bolts. Ubuilditplans.com offers free tech support for its customers and no hydraulics are required for these mini bulldozer plans. Prices and availability vary, so contact the company for more information.
Another mini bulldozer plan involves removing the hydraulic system from a riding tractor and using it in a dozer transmission system. A mini bulldozer runs well with a 12.5 horsepower engine, which is what several lawnmowers contain. More intensive, this plan calls for fabricating some of the pieces for the bulldozer, which a builder can do on his own or can have done at a machine shop. Builders may add metal or rubber tracks and customize this mini bulldozer to meet their needs.
