Conversion of the Neva walk-behind tractor into a multifunctional mini-tractor
Many craftsmen have learned to assemble a mini-tractor from a Neva walk-behind tractor to expand the functionality of the equipment. It should be noted right away that a powerful unit, preferably from 9 liters, is suitable for these purposes. With. Before you start work, you need to draw a kinematic diagram of the future homemade product. It will help you have an idea of what you are going to do. An example of a mini-tractor diagram can be seen in the photo.
The manufacture of a mini-tractor begins with the frame. It can be welded whole or broken. The second option is more difficult, but benefits from maneuverability. Weld a frame from a channel. For reinforcement, use a profile, pipes or corners. The one-piece design is a rectangle with a jumper for rigidity. The fracture consists of two half-frames. They are connected to each other by a movable unit - a hinge.
All frame elements are connected by welding. At complex joints, thick metal gussets are welded. To strengthen the frame, you can additionally use a bolted connection. You can make a solid structure or a fracture according to the proposed drawings.
The motor is placed on the finished frame. If it is located at the front, then the original width of the wheelbase of the walk-behind tractor is left. With a rear-mounted engine, the original wheelbase is extended.
To control you will need a steering column. It is usually removed from a passenger car. You can find hydraulic controls from decommissioned agricultural equipment. It’s easier to handle, especially if the frame on the mini-tractor is broken.
The driver's seat should be comfortable. It is also removed from old equipment.The seat is secured to the frame with an adjustable mechanism that allows you to change the height and angle of inclination.
Wheels on a mini-tractor are often fitted from a passenger car, but this choice is not always appropriate. Here you need to choose the right size. It is optimal when the diameter of the front wheels is 12–14 inches, and the rear wheels are 18 inches. If the wheels are incorrectly selected, the tractor will bury itself in the ground or the unit will be difficult to control.
The brake and clutch pedal are usually connected to the engine block using cables. The gear shift lever must be located near the driver's seat so that it is convenient to reach with your hands. After assembly is completed, the mini-tractor is run in. Only after this the homemade product can be subjected to load.
