What's the Matter with the Weakness Problem of Remote - Controlled Lawn Mowers? Now, the lawn mower manufacturer will explain it to you.
Reasons: There are two situations for the power shovel. One is that there is no power supply, which is a typical defect in the maintenance of the power shovel. The other is that the power shovel is too weak. The engine has no braking, and the screw rod or the screw rod is in tension. Eventually, the engine is severely crushed and even stops.
Solutions: Reverse the two hydraulic oil pipes of the hydraulic pump. If the slow leg is fast but the fast leg is slow, it proves that one pump is broken. Due to the defect in this situation, the hydraulic pump must be removed, a pump accessory must be replaced, and then the valve accessory check valve can be adjusted. At the same time, it solves the problem that the joystick is not ideal.
