The Case SR250 and SV300 skid steers and TR320 and TV380 compact track loaders now feature 90-hp, 3.4-liter Case diesel engines with the full high-pressure common rail (HPCR) design typically used in larger construction equipment.

Electro-hydraulic (EH) controls with switchable patterns are available on all Alpha Series models. This is especially helpful when two or more operators run the same machine. Operators can easily switch between control patterns based on preference.

Exceptional visibility, operator comfort, climate management and operator controls define the Case Alpha Series machines. The skid steer cabs, which are the widest in the industry, feature ultra-narrow wire side screens that improve operator visibility. Extra glass surface gives the operator 360-degree visibility.

The Alpha Series cabs also provide a superior climate management system. The sealed, pressurized cab significantly reduces the amount of noise and dust.

Dozer-style undercarriage

As in previous Case models, the upgraded Case TR320 and TV380 compact track loaders feature a dozer-style undercarriage, engineered to hold fast on steep slopes and take command of muddy or sandy terrain.

The undercarriage has a rigid track frame with fewer moving parts, so it is more durable and easier to maintain than suspension track systems.

Easy maintenance

Easy access to filters and engine fluids makes maintenance on the Case Alpha Series models a breeze. The regular maintenance points are grouped in one area so operators do not need to walk around the machine to find specific service points.

Maintenance points, such as the radiator, fuel filter, battery terminals and engine oil fill are easy to find under the engine compartment cover and door. A removable side panel provides access to the engine oil filter and environmentally friendly drain. Additionally, the oil cooler and radiator tilt out for easy cleaning.

O’Brien noted the importance of using ultra low sulfur diesel fuel with HPCR engines.

Fuel systems in the upgraded Case Alpha Series models include primary filtration of impurities down to 10 microns, and secondary filtration to 3 microns. Change intervals for both filters are at 500 hours.
