Description
Electric spreader motors overheat and blow main fuses when spinning through heavy wet sand during blizzard operations. The Buyers Products Company SaltDogg PRO4000H Hydraulic Poly Hopper Spreader with Auger harnesses direct truck central hydraulics to move heavy salt and sand without electrical motor burnout. It processes 4.0 Cubic Yards of heavy deicing media. Connecting this unit requires a truck equipped with a functional hydraulic wet line system.
A rugged double-wall high-density polyethylene hopper resists severe chemical corrosion and absorbs punishing loader bucket impacts without cracking. The hydraulic drive package uses two independent hydraulic motors running off high-pressure cast-iron gear sections with internal relief valves. A 5-1/4-inch heavy-gauge continuous steel auger rides in a stainless steel trough supported by heavy-duty flange-mounted ball bearings.
Hydraulic Deicing Fleet Hardware Platform
Direct hydraulic power provides unstoppable torque that chews through frozen chunks of road salt that stall electric motors. The adjustable poly chute directs spread patterns away from oncoming traffic lanes.
- 4.0 Cubic Yard capacity poly hopper handles up to 8000 pounds of coarse sand and bulk chemical deicer.
- Dual independent hydraulic drive motors power the heavy auger feed and spinner disc separately.
- Heavy 5-1/4-inch full-length steel auger forces tough material into the chute without bridge formation.
- 14-inch poly spinner disc resists corrosion and projects deicing media up to 30 feet wide across roads.
- Stainless steel inverted-vee assembly shields the auger from heavy overhead bulk material packing.
- Top steel screening grids filter out massive gravel chunks and frozen crusts during loader filling.
- Quick-detachable chute assembly swings away fast to allow swift trailer cleanout and servicing.
Hydraulic Circuit Pressure Bench Telemetry
Under maximum auger feed with wet gravel-salt mix, the hydraulic circuit pulls 12 GPM flow at 1850 PSI operating line pressure. Truck hydraulic fluid reservoir temperatures reach 152°F during sustained four-hour plowing and salting operations. Auger shaft speed stabilizes at 22 RPM while crushing frozen salt chunks. Operating sound emissions register 72 dBA measured five feet away from the rear chute.
Municipal Route Application Maintenance Rules
Highway road departments and heavy commercial plowing fleets gain immense durability from this hydraulic-driven hopper unit. Do not buy this spreader if your truck fleet lacks a dedicated hydraulic PTO pump system capable of 15 GPM continuous flow. Never run the hydraulic auger with foreign timber or large rocks wedged in the hopper trough.
- Grease the main auger end bearings using extreme-pressure synthetic grease every 20 hours of operation.
- Check all hydraulic hose fittings for leaks or weeping seals prior to every winter storm run.
- Inspect the inverted-vee mounting hardware inside the hopper for loose bolts each month of the plowing season.
