Model 950 XL 2 - Ejector Scraper Brochure

Ashland EarthmoversI-950 Ejector ScraperTHE I-950 is the smallest and most popular hydraulic ejection earthmover that Ashland Industries manufactures. Made for the agricultural and light industrial markets, this 9.5 yd3 scraper is a perfect match for 140 to 300HP, 2 to 4 wheel drive tractors. New in 2010, the I-950 was fitted with a larger 4” x 13” apron cylinder and an outboard apron pivot support for greater clamping force and a larger apron opening. Engineering modifications to the gooseneck and pole provide greater strength in the front section. The I-950 also implements a dual-plated floor, similar to larger models, which increases floor durability and provides added rigidity to the cutting edge.

First built in 1972, the Ashland I-series proves to be the scraper of choice for customers who want the “Cadillac of Scrapers.” We encourage you to carefully review the following five sections of profile information and compare it to other pull-type scrapers. The five areas that we will be covering include: • Pole: The front hitch portion of the scraper that connects to the tractor.• Front Section: Connects the pole to the scraper. The front-section of Ashland scrapers is the strongest on the market.• Apron: The front gate that provides the opening for material to be ejected. • Bowl: The bucket or “volume area” that will hold the material.• Pushoff: The moving rear wall of the scraper which moves forward to eject the material out of the apron opening. Rock solid,PROvENperformer.PoleA quality scraper starts with a quality pole. Ashland’s modern design includes a pole which runs through the draft line. This means the hitch itself is located in the middle of the pole, which makes the hitch mechanism substantially stronger. Ashland creates its hitches by bending a high quality steel plate into a “C” shape, narrow in the front and wide at the end. We then insert a solid steel trust block into the neck, which is welded from the inside out. Next, we set the yoke system in place and place a trust collar on the back side, which is welded 360 degrees around. This design gives Ashland scrapers a full range of motion from the hitch and maximum potential pull-through to the back side of the pole or the spindle base plate. The I-950’s spindle base plate is made of 4”x 6”x ½” steel. Before the spindles are attached, we insert a ½” steel plate into the rectangular tube. We then set the 3 ½” spindles onto the spindle base plate and weld them 360 degrees. Next, we support the spindles with two tapered ½” gussets. The formed hitch and the spindle base plate are then flipped upside down and welded together at 360 degrees. The scraper’s front section is completed with a 2-3/4” ball set. This high quality ball set is used to tie the pole into the front section. The ball is mounted to the spindle base plate, which is then set into a cast steel socket set. Having a ball and socket set allows you a complete range of motion in a confined space. By incorporating this ball, we also lower the pull point on the scraper. The pull point on the I-950 scraper is 22”. With this low pull point, less weight transfer will occur from the back tires, which allows the scraper to pull across surfaces more smoothly. Front SectionThe front section on Ashland scrapers has a long, paneled gooseneck design which allows the front section to grab onto the scraper at a better angle. More importantly, this design allows for a greater range of motion for the scraper’s dolly wheels. A longer front section places the dolly wheels farther away from the “fall zone” (77” away), so the wheels don’t interfere with the machine’s ejection process. The front section’s pole comes off the spindle base plate at a 48 degree angle and bends back at the box at a 42 degree angle. Product Profile: I-950 Ejector ScraperUnlike Ashland’s rounded front section pipe, many of our competitors use a square tube across their front section and another piece of square tube angled down to connect to the scraper’s pole. This design places the dolly wheels closer to the ejection area and allows more pressure to be pulled down from the machine’s front section. This unnecessary force and stress can cause cracking in our competitors’ front section member. Ashland’s front section is further equipped with ¾” hydraulic tubing. Commercial grade plastic clamps hold down the hydraulic pipes. These plastic clamps have a steel cap and are held down with two bolts. However, the clamps being plastic doesn’t mean they are inferior to steel clamps. Ashland has chosen to spend more money for these plastic clamps, because they create a longer lasting hydraulic system. Plastic clamps will act as shock absorbers and prevent metal-on-metal contact which would wear on the hydraulic lines. Also, by utilizing these plastic clamps, we have eliminated the need for sharp 90 degree turns in our hydraulic lines, which can cause damaging heat build-up. ApronThe apron of the I-950 scraper is a critical piece because it is the closing component of the bucket. By designing a strong apron, Ashland scrapers are better able to contain soil without any spillage. This apron also opens at an extra wide angle and won’t interfere with the ejection process. The cylinder that is used for this apron is 4” x 13”. By using the maximum cylinder stroke and strategic pivot points, the I-950’s apron opens to a gaping 55”. This wide apron opening paired with dolly wheels placed 77” away creates a very large fall zone for the scraper, which equates to fast and easy ejection. Ashland scrapers also have a tight tolerance between the apron and side walls, which prevents material from wedging in gaps and eventually bending the apron and sidewalls. BowlThe I-950 has a 9.5 cu. yd. heaped capacity and a 7.6 cu. yd. struck capacity. The back end of the bowl is the push off, the front is the apron, and the sides and floor are steel plates welded together. Unlike our competitors, Ashland uses dual plated flooring for its substructure. Competitors use inverted flat bar as the substructure for the floor, which is inferior because if Product Profile: I-950 Ejector Scraperan operator was to hit a rock while pulling at an angle, the floor would be prone to fold over and flatten out. If another rock were to hit, the floor would be more apt to bulge or be pushed up. The front section of the floor, where the scraper’s blade is located, is the one of the most important areas on the whole bowl. I-950s utilize a set of three blades. The middle blade (the frost bit) is the biggest at 3/4” x 8” x 54”. By designing a middle blade that juts out from the bowl, the scraper employs better suction and a better blade angle, which enables the scraper to collect more material with less horsepower. The scraper’s side blades are both 6” long and “L” shaped. These blades are set back 2” and are bolted to the floor and sidewalls. This design gives strength and protection to the sidewalls by absorbing the force of hitting rocks and stumps that are along the sides of the cutting path, thus preventing wear on the scraper’s sides. Behind the blades are a 3/4” steel plate (the frog) with punched holes. These punched holes act as a shield against dirt and wear on the plow bolts and nuts. The frog also serves as reinforcement for the channel iron underneath the pan.PushoffThe pushoff on the I-950 looks like a large “T” shape with a thick base. At the top of the pushoff, there is a screen (headache rack) that is 22” high at a 45-degree angle from the bowl and prevents dirt from spilling out the back. By tilting the headache rack forward, dirt is cycled over itself and fills both the front and back of the scraper evenly.The rear frame of the pushoff has a wide stance of 48.5”. The front of the pushoff is 44” wider than the back. By designing a wide pushoff area, the scraper can more easily eject an unbalanced load. Narrow-framed pushoffs have a harder time ejecting uneven loads because they tend to bend or twist under the uneven force being applied. The rear framework of the scraper and the pushoff is a welded system. This system consists of three pieces of rectangular tubing welded into a square shape and then welded onto a round tube back bumper. This frame also wraps around the scraper and ties to the trailing arms of the front section. The pushoff cylinder is a 4” x 54” cylinder with a 2” rod. The pushoff cylinder is tied to the rest of the hydraulics through a hydraulics manifold system. This system consists of a hydraulic block that has a sequence valve and counterbalance valve built into it. When you run the hydraulic circuit to the block, both the apron cylinder and pushoff cylinder are connected. After the apron opens, the pushoff cylinder automatically starts to push because of the sequence valve. The apron will remain open until the pushoff cylinder is fully retracted and the apron is closed, due to the system’s counterbalance valve.Product Profile: I-950 Ejector Scraper Wheel SystemSome of the general specifications that are often overlooked on scrapers are the tires, hubs, and bearings. The rear tires on Ashland scrapers are a 16.9 x 24, 10-ply ANS tire. The front dolly wheel tires are a 16.5 x 16.1, 10-ply ANS tire. Both sets of tires are diamond patterned, which explains their “ANS” label, meaning All-Non-Skid. These tires are designed for slopes, terraces, site scraping, and even road making.Product Profile: I-950 Ejector Scraper
