Backhoes

Your hydraulic fluid level is low, your hyd. pump is weak, your hyd. filter needs replacing, there is a spring release that is activated by hydraulic pressure under the machine, above the transaxle, if it does not receive enough hydrulic pressure, it will not release completely..

it might be underneath the engine. it is completely enclosed be a cover that has a nut on the bottom of it. its about 2.5 feet from the oil tank.

The operating parts consist of a boom, hinged at its base end at the machine, and a stick, pivoting on the outer end of the boom. The stick extends above and below its pivot point, with the digging bucket on the lower end and the retracting cable at its upper end. A second cable, the digging cable, is attached to the lower end of the stick, near the bucket.

The digging and retraction actions of the cables is straightforward. To lift the boom/stick/bucket assembly, the digging cable is locked and the retraction cable is pulled in. With the digging cable locked, the boom and stick assembly becomes a ridged triangle and is forced to move up as the retracting cable is shortened.

After the bucket is raised, the boom is pivoted to the dump site, the retraction cable is locked and the digging cable is allowed to play out. The Retracting cable holds the boom and stick assembly in its elevated position and its weight forces the stick and bucket outward until the load is dumped.

The cubic meters of aggregate that a backhaul can excavate in an hour is dependent upon the size of the backhoe. Typically, a backhoe can ask of a 100 cubic meters of aggregate per hour.
