Need help?Do you have a question about the Husky H6000 and is the answer not in the manual?
The Husky Liquid Manure Pump H5000/H6000 is a robust piece of agricultural equipment designed for the efficient agitation and transfer of liquid manure. This manual serves as a comprehensive guide for operators, covering safety, operation, and maintenance procedures to ensure years of trouble-free service. The pump is engineered to move liquid manure from storage facilities to hauling tanks, alternative storage, or to feed high-pressure irrigation systems. Its design incorporates features suggested by users, aiming for maximum efficiency and ease of use.
At its core, the Husky Liquid Manure Pump utilizes a PTO-driven impeller or fan assembly to move manure through a pipe system. Manure is drawn from the pit or storage area and discharged through a pipe attached to the top of the pump. The H5000 model is designed for tractors with 70 to 100 HP and operates at 540 RPM PTO (1:1.35 ratio), though its gearbox can also be configured for 1000 RPM (1.35:1 ratio). The H6000 model is specifically designed for 1000 RPM (1:1 ratio) and requires a 150 HP tractor. Running the H6000 at higher RPMs could damage the gearbox and drivetrain. The pump is available in various lengths to accommodate different pit depths, ensuring the PTO shaft operates as straight as possible to minimize vibration, prevent shear pin failure, and reduce premature bearing wear.
Optional equipment enhances the pump's versatility. These include a hydraulic or manual deflector/crustbuster, which can be used to direct the manure stream to break up crusts on the surface of the pit. An electric drive option is available for specific applications. For more intense agitation, a hydraulic propeller agitating fan can be integrated. A two-point hitch pump model is also offered, providing different attachment options for tractors.
The manual emphasizes safe and efficient operation, urging all operators to read and understand the safety, operation, maintenance, and troubleshooting information. New operators are encouraged to familiarize themselves with the machine's controls and functions.
For trailer models, installation involves backing the pump to the pit edge, connecting hydraulic hoses, and unlatching brackets to allow the pump to slide. The pump is then tilted and lowered into the pit using hydraulic controls. It's recommended that the pump rests on the pit floor, though it can operate without doing so. Once in the pit, the hitch must be unhitched and re-hooked to the back tongue, with the pump secured to prevent rolling. Tractor wheels should be blocked.
Two-point hitch models mount directly onto the tractor's hitch arms. The pump is positioned straight behind the tractor, and a hydraulic cylinder tips it into the pit. Operators must ensure the tractor is heavy enough to support the pump and prevent the front end from lifting. Parking brakes should be firmly locked. When removing the pump, care must be taken to avoid catching agitation tees on concrete.
Before starting the pump, the top valve should be closed. Agitator valves are then opened, and the pump is started slowly to ensure proper functioning. The choice between top and bottom agitators depends on the manure's consistency, with the top agitator being suitable for breaking up crusts. The manual or hydraulic vertical deflector can be used to direct the stream for crust breaking. Agitator spouts can be rotated hydraulically (CW or CCW).
Once the pit is agitated and solids are broken up, hauling can begin. Agitation can continue between loads. When filling a spreader, the tractor's speed should be reduced, or the PTO turned off. The top valve is opened using the hydraulic lever. Foam often forms during loading, indicating the spreader is nearly full. Slowing the stream can help reduce foam. It's generally not necessary to close agitator valves during pumping, as the pump will still operate efficiently with one open. The pump is designed to withstand accidental closure of all three valves while running.
The manual provides a detailed maintenance schedule, starting with a break-in period. For new pumps, all grease points should be lubricated, gearbox oil checked (1/2 full), and wheel bolts torqued. After initial road travel (40 and 100 miles) or use (2 and 5 hours), wheel bolts should be re-torqued, hardware checked, and all grease points lubricated.
The pre-operation checklist emphasizes lubricating the machine, using an adequately powered tractor, ensuring proper attachment to the tractor with a drawbar pin and retainer, and securely attaching the PTO driveline with correct overlap. PTO shields must be in place, rotate freely, and telescope freely, with safety chains secured. Hydraulic systems require inspection of lines, hoses, fittings, and connectors, ensuring they are tight and clean. The tractor's hydraulic reservoir must be filled to specification, and its hydraulic system must match the pump's requirements. Tire pressure and wheel bolt torques should be checked, and any lights, reflectors, or SMV signs kept clean.
Service and maintenance guidelines cover fluids and lubricants. An SAE multi-purpose high-temperature grease with EP performance and at least 1.5% molybdenum disulfide is recommended for general greasing. Esso EP2 or equivalent bearing grease is specified for wheel bearings. SAE 90 EP gearbox oil is recommended for the gearbox. Lubricants should be stored in clean, properly labeled, and sealed containers to prevent contamination.
Greasing should be done daily using a hand-held grease gun to avoid damaging bearing seals. Grease fittings should be wiped clean before greasing, and broken fittings replaced immediately. If a fitting won't take grease, it should be removed, cleaned, and replaced if necessary.
Gearbox maintenance includes keeping the vent plug clean and changing oil at regularly scheduled intervals. Oil should be drained at operating temperature. The oil should be monitored for metal fragments, which could indicate premature wear. The gearbox interior should be cleaned with a solvent, refilled with new oil, and reinstalled.
Bearing service is crucial. The bottom marine bearing is lubricated by manure itself and requires no attention during use. Wear is checked by lifting the fan when the pump is out of the pit; if the fan moves over 1/2 inch (12.7mm), the bearing needs replacement. The central oil-impregnated wooden block bearing keeps the shaft from whipping; if it wears 1/2 inch (12.7mm), it also needs replacement. The manual provides detailed steps for changing bearings, including removing the gearbox, shaft, and specific bolts.
PTO driveline servicing includes greasing knuckles, the drive knuckle below the gearbox, and the PTO shield daily. Annually, the PTO should be pulled apart and the telescope greased, and the gearbox oil changed.
Wheel bearing greasing involves jacking up the axle, removing the hub cap, cotter pin, nut, and hub to expose the bearings. Bearings should be re-greased with Esso EP2. If dirty, they should be washed with a solvent. All components should be liberally greased, then the hub reinstalled and secured.
At the end of the season, a thorough clean-up is recommended. The pump's exterior should be washed with a hose or pressure washer. If temperatures are below freezing, ensure water drains to prevent freezing. Manure acids can affect the pump, so storing it away from the pit, preferably indoors, is good practice. A small canister sprayer with light oil can be used before and after use.
Before removing the pump from storage, all grease fittings should be lubricated to remove condensation. Wheel bolts should be torqued, and tire pressure checked. The gearbox oil level should be checked to be 1/2 full.
The manual also includes a troubleshooting section for common issues like the pump fan not running, manure not pumping, gearbox overheating, and leaks, providing potential causes and solutions. It emphasizes contacting the dealer or factory for assistance with complex problems.
