John Deere M665 Zero-Turn Mower

The John Deere M665 is a zero-turn mower produced between 2000 and 2001. Designed for landscaping and turf maintenance, this machine is engineered for maneuverability and efficient cutting performance on large areas.

Engine Specifications

The M665 is powered by a Kohler CH25S gasoline engine. This 2-cylinder, air-cooled unit features a displacement of 724 cc (44.2 ci) and provides a power output of 25 hp (18.6 kW). It utilizes an electric starter and a dry-type air cleaner. The engine operates with a 9:1 compression ratio and requires 2.1 quarts (2.0 L) of oil for lubrication.

The machine employs a belt-driven hydrostatic transmission manufactured by Hydro-Gear. This system provides infinite forward and reverse speed control, allowing for precise operation. The tractor is configured as a two-wheel-drive unit and is equipped with power steering to facilitate navigation, while mechanical band brakes provide the necessary stopping capacity.

Mowing and PTO Systems

The mower is fitted with a 60-inch cutting deck, designed for wide coverage. It features an independent mid-mounted Power Take-Off (PTO) shaft, which is engaged via an electric clutch system, ensuring consistent power delivery to the implement.

Dimensions and Electrical

The unit sits on a 52-inch wheelbase with an overall length of 79 inches and a ground clearance of 5 inches. It uses lawn and turf tires sized 13x5.00-6 in the front and 23x10.5-12 in the rear to minimize surface damage. The electrical system operates on 12 volts, powered by a battery with a 470 Cold Cranking Amps (CCA) rating and a 15-amp charging system.
