1. Scope This specification defines the minimum performance and construction requirements for a heavy-duty compact articulated utility tractor equipped with a high-capacity front-mounted snow blower attachment.

The equipment will be utilized by the California Conservation Corps (CCC) to support winter operations, including snow removal, lot clearing, and sustained maintenance activities in severe alpine environments.

2. Codes, Regulations, and Standards Laws, regulations, standards, and specifications referenced in this document in effect on the opening of the Invitation for Bid (IFB), form a part of this specification. The products covered by this specification shall comply with all applicable laws, regulations, and industry standards including, but not limited to, the following:

2.1 Code / Standards

• SAE J1995 — Engine Power Test Code

• ISO 3471 — Roll-Over Protective Structure (ROPS)

• ISO 3449 — Falling Object Protective Structure (FOPS)

• IEC 60529 — IP67 Ingress Protection

• ISO 20653 — IP69K Ingress Protection

2.2 Regulations

• EPA Tier 4 Final — Federal Emissions Regulation for Nonroad Diesel Engines (40 CFR

Parts 1039, 1065, and 1068).

• CARB Tier 4 Off-Road CI (California) Title 13, CCR §2423

3. Requirements

3.1 Engine

• The engine shall be a four-cylinder, liquid-cooled, common-rail turbo-diesel unit designed to deliver reliable performance under continuous heavy-duty winter operational demands.

• Gross engine horsepower shall be not less than 74 HP SAE J1995 or equivalent.

• The engine shall comply with EPA Tier 4 Final emissions standards.

3.2 Transmission

• The tractor shall be capable of achieving a minimum transport travel speed of 25 mph

(40 km/h) to ensure efficient transit between work locations.

• The transmission shall be a continuously variable hydrostatic drive or a dual-range hydromechanical drive, engineered to provide smooth, controlled operation under varying load and terrain conditions.

• Transmission shall support seamless transition between low-speed precision control and higher travel speeds without torque interruption.

• Transmission components shall be heavy-duty, designed for sustained operation in freezing alpine environments, with thermal protection to maintain hydraulic and mechanical efficiency.

• The tractor shall be equipped with a neutral-start safety interlock shall prevent engine start-up while the transmission is engaged.

Kadhim, A Page 3 of 5 08/14/2026

• The drive system shall remain fully functional during continuous snow-blower duty cycles without loss of hydraulic drive pressure or mechanical output.

3.3 Driveline

• The driveline shall feature permanent, full-time four-wheel drive (4WD) with mechanical locking differentials on both axles for maximum traction. Manual locking hubs are not included to ensure continuous 4WD operation.

3.4 Axles

• The tractor shall be equipped with front and rear full-time mechanical or electronic locking differentials, or an equivalent manufacturer provided traction management system, capable of providing comparable maximum traction and torque delivery under low traction winter, alpine, and snow removal conditions.

• The tractor shall be equipped with front and rear axles designed to support the specified Gross Vehicle Weight Rating (GVWR), front attachment loads, and continuous municipal snow removal operations while maintaining structural integrity, traction, and stability during severe winter conditions and steep grade operation.

3.5 Brake

• The braking system shall consist of four-wheel hydraulic service brakes supplemented by an independent electric parking brake, ensuring reliable stopping performance and secure vehicle hold during winter and alpine operational conditions.

3.6 Electrical

• The unit shall be equipped with a full LED auxiliary working light package providing high-intensity illumination to the front, rear, and sides of the tractor, ensuring maximum visibility during night operations, low-light conditions, and severe winter environments.

• LED housing shall meet or exceed IP67/IP69K ingress protection standards to prevent failure due to blowing snow, ice buildup, and water spray.

3.7 Chassis, Steering, & Dimensions

• The chassis shall feature a center-articulated frame equipped with hydraulic oscillation, engineered to maintain constant wheel-to-ground contact, improve maneuverability, and ensure optimal stability during winter operations on uneven or icy terrain.

• The tractor’s outer width shall range between 54 inches and 62 inches, dependent on the selected tire configuration, to ensure maneuverability within narrow pathways and constrained winter-maintenance environments.

• The tractor shall have a minimum unladen gross vehicle weight of 6,500 pounds, with a permissible gross vehicle weight rating (GVWR) to 12,000 pounds maximum.

• This tractor shall comply with applicable industry safety standards, including ISO 3471 (ROPS) and ISO 3449 (FOPS), as well as all applicable federal and state regulations governing municipal utility tractors.

• The tractor shall comply with applicable industry safety standards for municipal-grade utility tractors, including, at a minimum, Roll-Over Protective Structure (ROPS) in accordance with ISO 3471 (or equivalent), Falling Object Protective Structure (FOPS) in accordance with ISO 3449 (or equivalent), and all applicable federal and state safety requirements.

3.8 Power Take-Off (PTO), Hydraulics, Front Attachment System

• The tractor’s front PTO shall provide selectable 540-RPM and 1000-RPM operating speeds, where 540 RPM delivers lower-speed, high-torque output suitable for compact and mid-sized implements, and 1000 RPM provides higher-speed, lower-torque output designed to efficiently transmit greater horsepower for heavy-duty, high-capacity attachments.

• The tractor shall be equipped with a Category II heavy-duty front hitch incorporating double-acting lift cylinders, providing a minimum lift capacity of 5,500 pounds to support high-torque, front-mounted snow-removal implements and associated winter-operations equipment.

• The hydraulic system shall utilize a multi-pump configuration capable of delivering a minimum of 25 GPM at 3,500+ PSI, ensuring sufficient high-flow output for continuous-duty winter implements and demanding snow-removal operations.

• The hydraulic system shall provide a minimum of three double-acting electro-hydraulic control circuits, each equipped with quick-connect couplings to enable rapid attachment and reliable operation of front-mounted implements.

3.9 Operator Enclosure (Cab)

• The tractor shall feature a fully enclosed, single-occupant panoramic cab that is

ROPS/FOPS-certified, providing full-surround visibility and operator protection.

• The cab shall be equipped with a heavy-duty, fully integrated heating, defrosting, and air-conditioning system designed to maintain operator comfort and ensure clear visibility.

• Air-suspension heated comfort seat

• The operator interface shall include a multi-function, programmable joystick integrated into the armrest, enabling one-hand control of ground drive, directional travel, and all primary front-mounted implement functions.

• The cab shall include a heated front windshield and heated exterior mirrors to ensure optimal visibility and safe operation in freezing temperatures, heavy snowfall, and icy alpine conditions.

3.10 Snow Blower Attachment

• The implement shall be driven through the tractor’s front PTO shaft, providing direct engine-driven torque transfer for maximum performance in heavy, wet snow conditions.

• The snow-blower attachment shall be a heavy-duty unit utilizing either a dual-stage or ribbon-type assembly, engineered to deliver high-capacity snow processing performance suitable for deep, wet Sierra snow conditions.

• The snow-blower attachment shall provide a clearing width ranging from a minimum of 55 inches to a maximum of 65 inches, ensuring full coverage of the tractor’s tire track width during winter operations.

• The snow-blower attachment shall include a 360-degree hydraulically actuated rotating discharge chute paired with a hydraulic deflector tip, providing precise directional control of snow discharge from within the operator cab.

• The snow-blower attachment shall incorporate replaceable hardened-steel cutting edges and adjustable skid shoes, ensuring durability, optimal ground clearance, and extended service life during heavy winter operations.
