BRISK, WHEEL, REVERSE

On the kinematics of the transmission, I remember, had to suffer before he found a rather simple (see Fig.) and acceptable to the existing “material base” solution. The same can be said about the layout. Although certain components of the design turned out too heavy-squat, but the margin of safety is not deprived. Mini tractor (in the future I will call him MT) working safely and transporting cargo weighing up to one ton, and hay (trailed mounted mower), and plowing, and when cutting grooves. Moreover, while plowing is used (depending on the severity of the soil), or second, or third speed. And they are great. A normal horse plow, as it turned out, there is almost unacceptable, so I had to make seeu: slightly larger in size, with elongated toe shield and a smaller twist of the blade (see Fig.).

The supporting basis of the whole structure of MT is its frame. Without welding this, of course, is not to be done. Increased strength and give the channel side members and cross member bracket 5 of the front axle (of the same steel channel 16), and the gusset plate of 5 mm St3, and welded “turn” the steering column bracket. And, of course, the rear axle. Rigidly attached to the spars steel 8 mm plates, strapped on the eight M10 bolts with nuts, “zakonchennyi” washers, it is like a logical continuation and completion of the welded frame.

 

Rear axle of the car GAZ-21 “Volga”, a shortened (trimmed) to width (flange axle) 800 mm (according to the method, largely similar to what published in number 2 of the magazine in 1993). Let me just note that the rivet heads fixing the stockings, was cut down. The remaining part is pushed inside of the stocking.

 

 

Mini tractor (lighting equipments conventionally not shown):

1 — front wheel driven with a pneumatic tire and a 5.0—10″ (2 PCs.), 2 — line steering (motorized SZA), 3 — unit power (motorized SZA), 4 — hood of turning a homemade, 5 — steering column (from the GAZ-21 “Volga”), 6 — wheel steering with the handle “ball” (from the loader), 7 — the lever is “reverse”, 8 — lift lever hinged frame (latching, bus LiAZ), 9 — the levers (right and left) including brakes, 10 — gas tank bracket (2 PCs), 11 — seat 12 — tank 13 — wing peligrosamente (2 PCs), 14 — raising mechanism for the hinged frame (lever), 15 — plate installation of mounted implements, 16 — the body of the plough, 17 — blade, 18 — Board field, 19 — blade with an elongated toe, 20 — leading rear wheel with pneumatic tyre 6,5—20″ (2 PCs.) 21 — reverse gear homemade (description and sketches of designs, see No. 1Г89), 22 — frame MT, 23 — steering mechanism (from the GAZ-21 “Volga”), 24 — transmission power circuit PR-19,05 (from discarded agricultural machinery), 25 — pedal “grip”, 26 — a panel instrument, 27 the lever, kickstarter, 28 — pedal “gas”, 29 — cylinder hydraulic brakes main, 30 — a box tool, 31 — frame is hinged, 32 — support weld hoist frame hinged, 33—., 34 — a towing device, 35 — axle rear (from the car GAZ-21 “Volga”, cropped), 36 — fry steering, 37 — bracket gearbox.

 

 

Raspressovki hose from the crankcase a reducer of the rear bridge was done pretty easily, using special mandrels and… sledgehammer. Stockings were protocells to ready the bridge had different lengths of axle shafts and how you can better fuse with the reverse gear (also, incidentally, shifted to the left, when viewed in the direction of movement of MT in normal mode). Because it allows to reduce the fracture of the gimbal and increase the load on the left rear wheel when plowing. No need to install additional counterweights, tractor sustained in the furrow.
