Question 1

What are the key specifications of this 2001 Gomaco 9500 Trimmer/Placer?

Accepted Answer

This 2001 model features Gomaco's unique front-mounted, two-track design with hydrostatic powered crawler tracks. The standard trimmerhead is 12.7 feet wide with 107 teeth. The machine includes a 35-foot rear conveyor (36 inches wide) with 160-degree hydraulic swing and 16.2-foot maximum elevation. The front transfer conveyor is 14 feet with trimmer or 17 feet with placer configuration. Shipping dimensions are 21.1 feet long, 12 feet wide, and 10.4 feet high. The prime mover with transfer conveyor weighs approximately 50,000 pounds.

Question 2

What engine powers the Gomaco 9500 and what is its output?

Accepted Answer

The 2001 Gomaco 9500 was typically equipped with either a Cummins M11 diesel engine (325-330 hp) or Caterpillar C9/C11 diesel engine (325-385 hp depending on configuration). The specific engine in this unit should be verified with the seller. The engine drives a closed-loop hydrostatic system with multiple pumps: two for travel, one for the trimmerhead, and one for the conveyor system, providing robust power distribution across all functions.

Question 3

How does the front-mounted trimmer design differ from three-track machines?

Accepted Answer

The front-mounted, two-track design allows the 9500 to execute a 360-degree turn within its own length, unlike three-track machines requiring wide turning radii. The trimmer or placer attachment is positioned directly in front of the operator platform, providing unobstructed visibility and allowing trimming to the very end of each pass or within inches of front obstacles. This design also offers low ground pressure through large track contact area while maintaining high tractive effort.

Question 4

What is the trimming speed and production capacity?

Accepted Answer

The standard 12.7-foot trimmerhead has a toothtip rotational maximum speed of 1,323 feet per minute (403 meters per minute). The hydrostatic direct drive motor provides ample power for continuous trimming. Production rates vary by material type, grade conditions, and trimming depth, but contractors report the 9500 is capable of preparing hundreds of feet of grade per hour. The POS-A-TROL feature automatically adjusts travel speed based on trimmer circuit pressure to maintain maximum production speed.

Question 5

How accurate is the grading with the 9500's control system?

Accepted Answer

The 9500 features dual grade control capable of sensing stringline on both sides simultaneously for precise elevation control. Extended sensor arms can accommodate stringlines set up to 40 feet apart, maintaining accuracy through transitions. The proportional hydraulic system with proportional valves in lift, swing, and grade circuits provides smooth, responsive control. While this 2001 model predates the current G+ system, it includes GOMACO's proven grade control technology for accurate trimming to specification.

Question 6

What is the conveyor capacity and belt speed?

Accepted Answer

Both the front transfer conveyor and 35-foot rear conveyor operate at 512 feet per minute (156 meters per minute) belt speed. The conveyors are 36 inches wide and use a hydrostatic closed-loop drive system for consistent power delivery. The rear conveyor can swing 160 degrees and reach heights up to 16.2 feet, allowing placement of trimmed material past adjacent lanes, over stringline, or directly into haul units. Two 1,500-pound winches assist with conveyor operation.

Question 7

What types of projects is the Gomaco 9500 best suited for?

Accepted Answer

The 9500 excels on highway and interstate grade preparation, airport runway and taxiway construction, parking lot subgrade work, and large commercial site development. Its versatility allows use as a grade trimmer preparing subbase, a shoulder trimmer working alongside existing pavement, or a concrete placer feeding slipform pavers. The machine is particularly valuable on projects requiring high-volume material removal or precise grade preparation for subsequent paving operations.

Question 8

Can this machine be converted between trimmer and placer configurations?

Accepted Answer

Yes, one of the 9500's key advantages is quick conversion between trimmer and placer. The front-mounted design allows easy detachment of the trimmerhead and attachment of a receiving hopper for concrete placing. The receiving hopper holds 1.47 cubic yards and includes a split-flight hydraulic 12-inch diameter auger. Optional hydraulic front lifting arms facilitate loading and unloading of attachments without additional equipment. This versatility maximizes asset utilization across different project phases.

Question 9

How does the 9500 work as a concrete placer?

Accepted Answer

In placer configuration, the 9500 uses a quick-hitch system to lock onto dump trucks. With the truck in neutral, the 9500 pushes it while concrete discharges into the receiving hopper. The hydraulic auger carries material from both sides to center, onto the transfer conveyor, and then to the 35-foot rear placement conveyor. The operator uses a ground-level remote to control hitch, hopper vibration, and height adjustments. This system enables fast, accurate concrete placement in front of slipform pavers.

Question 10

What regular maintenance does the Gomaco 9500 require?

Accepted Answer

Daily maintenance includes inspecting and replacing worn trimmerhead teeth (easy front access simplifies this task), checking hydraulic fluid levels in the 221.5-gallon reservoir, greasing track and pivot points, and inspecting conveyor belts. Engine maintenance follows manufacturer specifications for oil changes, filter replacements, and fuel system service. The hydrostatic drive system requires periodic hydraulic filter changes. Track tension should be monitored and adjusted as needed. The front-mounted trimmer design significantly reduces maintenance downtime compared to other configurations.

Question 11

How available are parts for a 2001 Gomaco 9500?

Accepted Answer

Gomaco Corporation maintains comprehensive parts support for legacy equipment through their parts department in Ida Grove, Iowa. As a long-established manufacturer since 1965, Gomaco stocks parts for older models and can fabricate specialty items if needed. Common wear items like trimmerhead teeth, hydraulic components, and conveyor belts are readily available. Engine parts depend on whether the unit has a Cummins or Caterpillar engine—both manufacturers have extensive dealer networks. Being a 2001 model, verify parts availability for specific components before purchase.

Question 12

What operator skills are needed to run this equipment effectively?

Accepted Answer

Operators should have experience with heavy equipment, understanding of hydraulic systems, and knowledge of grading principles. Previous experience with dozers, motor graders, or similar equipment is beneficial. Gomaco provides operator training that covers machine operation, grade control, conveyor operation, safety procedures, and maintenance. Understanding stringline setup and grade checking is essential. Most experienced equipment operators can become proficient within several days of training, though mastering grade control in varying conditions takes additional practice.

Question 13

How is the Gomaco 9500 transported between job sites?

Accepted Answer

The 9500 transports on a lowboy trailer or RGN (removable gooseneck) trailer. Shipping dimensions are 21.1 feet long, 12 feet wide, and 10.4 feet high without exhaust pipe and air cleaner. The trimmerhead or hopper detaches easily—the machine simply backs off without additional equipment needed. Total transport weight including the prime mover (50,000 lbs), rear conveyor assembly (4,628 lbs), and standard 12.7-foot trimmerhead (9,470 lbs) is approximately 64,000 pounds. Permits may be required for oversize/overweight loads depending on jurisdiction.

Question 14

What site requirements are needed for the 9500 to operate?

Accepted Answer

The site must provide adequate space for the machine's 57.7-foot operational length with conveyor extended, plus turning clearance. While the two-track design allows tight maneuvering, ensure sufficient room for 360-degree turns if needed. The work area requires proper stringline setup unless using a sonar sensing system for second-pass trimming. Access routes must support the machine's 50,000+ pound weight. Fuel capacity is 199.5 gallons—ensure diesel availability on site or plan for refueling logistics. The machine performs best on relatively stable subgrade that supports track loading.

Question 15

What are the operational limitations of this 2001 model?

Accepted Answer

As a 2001 model, this machine lacks the current G+ control system and 3D stringless guidance capabilities found on newer units, requiring traditional stringline setup. The technology is proven but older, so modern contractors may find the controls less intuitive than current systems. Weather limitations include operation in extreme cold (hydraulic fluid specifications), wet conditions affecting track traction on unstable grades, and high winds potentially affecting material discharge from conveyors. The front-mounted design requires forward visibility—dense fog or darkness limits effectiveness. Maximum trimming depth depends on material type—hardpan or heavily compacted materials may slow production compared to loose soils.
