We selected agricultural methods are not grasped

Check the appearance of the product: From all directions around to see the whole machine has no distortion. There is no rust where sheet metal is not smooth, there is no leakage of paint, paint flow, without casting porosity, blisters, burrs, plastic colors, the wall thickness is not uniform, tires, belts and other rubber between triangular No deformation aging, there are no leaks, oil spills place. Should be fixed on the equipment nameplate, see the nameplate equipment model is not, and they need the same. Some evidently almost from the appearance, the name is very similar, but can not be used to buy back a little attention. No nameplate, site, basically not a regular production of the company's products, quality is difficult to guarantee.

Security check: national mandatory standards, safety of agricultural products must pass a safety protection device. Like the initiation claws, fan, pulleys, PTO shaft, exhaust pipe, chain drive and the knife shaft assembly parts and so have shields. Pedals should be skid plates, easily hurt in the place you want to paste the yellow or red warning signs. Throttle, Dangba other places, have a significant operation symbols.

To check the quality of assembly: Check the farm throughout parts and components is not complete and not damaged; portable power sprayer installation is not very good. Duly qualified product assembly marks are very clear, obvious, such as the gear assembly marks, piston crown markings should be clear and in good condition. Check all screws, nuts are not all on tight, never use wire or nails instead of cotter pin. All rotating, rotating flexible drive and operating system, without sticking, loosening. If the optional rotary tiller, to see the knife shaft is not rotating flexible, without significant axial movement, catching and abnormal sound, hanging files handy, no missing parts, no leakage. Rotary Blade specifications, models are not unanimous.

Good test machine check: buy tractors, farm vehicles, etc. must be commissioning. Look after starting the engine shake do not shake, the sound is not normal, is it easy to turn off, take no black smoke, Guadang, direction, brake, throttle is not so that; choose manual sprayer (control) is best for simple spray test a trial, such as the water added to the bottle plastic sprayer kits, see the spray mist nozzle spray droplet is small, uniform, does not drip, valves and joints can not "run, run, drip, leak," and so on.
