Powered by 13.6-kW (18.2-hp)*, 993-cc (60.6-cu in.), 3-cylinder, liquid-cooled, four-cycle diesel engine

The Gator™ TH 6x4 Diesel Utility Vehicle is powered by a 13.6-kW (18.2-hp)*, 993-cc (60.6-cu in.), 3-cylinder, liquid-cooled, four-cycle diesel engine.

*The engine horsepower information is provided by the engine manufacturer to be used for comparison purposes only. The actual operating horsepower will be less.

The engine offers the following performance and reliability features:

• Overhead valve design for greater efficiency and fuel economy
• Full-pressure lubrication system with replaceable oil filter 
• Dry replaceable single-element air cleaner with remote intake
• Indirect injection diesel with glow plugs insures fast starts in cold temperatures
• Spark arresting muffler (optional)
• Dual radiator system for additional cooling capacity
• Deaeration tank decreases service time and ensures coolant will be free from trapped air
• 18.9 L (5 U.S. gal.) fuel tank capacity

Dual radiator system

Single fill point (A) and overflow bottle (B)

• Two radiators - one under the seat and one under the hood
• Overflow bottle added under the hood
• Single under-hood fill point for the entire cooling system
• Increases vehicle cooling capacity by 30 percent to handle high ambient temperature conditions
• Decreased occurrence of cooling system vapor lock by moving the front radiator to a high point in the system and having an overflow bottle

Precision-engineered drive system optimizes hauling, towing, and hill-climbing capabilities

The Gator™ TH 6X4's power is transmitted from the transaxle to the center axle. The rear axle is driven by roller chains from the center axle.

1. High-flotation tires
2. Transaxle
3. Chain drive
4. Engine
5. Variable-speed drive

Variable-speed drive

The variable-speed drive consists of two clutches connected by a drive belt:

• Drive clutch is attached to and rotated by the engine.
• Driven clutch is attached to and drives the transaxle.

Features include:

• Infinite selection of speeds (0 km/h to 32 km/h [0 mph to 20 mph])
• No shifting necessary as operator increases speed
• Adjusts speed to the load to avoid bogging down when going up a hill or through challenging conditions because the wrong gear was selected

1. Idle sped
2. Moderate speed
3. High speed
4. Drive clutch
5. Driven clutch

1. As the engine speed increases, the spring-loaded drive clutch is closed by weights being forced out by centrifugal force.
2. As the drive clutch closes, the belt rides up to the largest diameter of the drive clutch and forces open the driven clutch.
3. With the belt running in the smallest diameter of the driven clutch, the speed being transferred to the transaxle is increased.
4. The driven clutch is designed to sense varying loads (inclines, mud, etc.) and constantly adjusts the drive speed upward or downward, so the engine rpm remains constant at constant throttle position.

Transaxle

The transaxle is fully enclosed and runs in oil for reliability. Helical gears are used for quiet operation. The differential design reduces scuffing of the turf during turns because the inside wheels turn slower than the outside wheels (vehicles that have a solid axle shaft must skid the inside wheel when making a turn).

Traction assist (differential lock) is built into the transaxle:

• Allows locking the rear drive wheels together
• Provides increased traction in tough spots

The neutral start safety interlock is provided for the engine ignition system.

Bolt-on cast-aluminum rear axle housings provide an extremely strong supporting structure.

• Large, sealed bearings are located inside the housing for better protection
• Forged splined shaft for increased torsional strength
