SECTION 5: MAKING ADJUSTMENTS

WARNING: NEVER attempt to make any adjustments while the engine is running, except where specified in the snow thrower and/or engine operator’s manuals.

Shave Plate

•To check the adjustment of the shave plate, place the unit on a level surface. See Figure 8. The wheels, shave plate and augers should all contact level surface. Note that if the shave plate is adjusted too high, snow may blow under the housing. If the shave plate wears out excessively, or the unit does not self-propel, the shave plate may be too low and needs to be adjusted.

NOTE: On new units or units with a new shave plate installed, the augers may be slightly off the ground.

Belt Tension

Periodic adjustment of the belt tension may be required due to normal stretch and wear on the belt. Adjust the belt tension, following instructions below, if the augers seem to hesitate while turning although engine maintains the same speed.

•The upper hole in the control handle provides adjustment for belt tension. To adjust, disconnect the “Z” end of control cable from the bottom hole in the control handle. See Figure 10 . Hook the cable into the upper hole in control handle as shown.

At the heart of the 721E is its dependable 2-stage system, which efficiently displaces snow with remarkable speed and effectiveness. The first stage consists of an intake auger that gathers the snow, while the second stage propels it out of the chute, ensuring maximum clearance in minimal time. The 721E features a 21-inch clearing width, making it ideal for handling snow in residential driveways and sidewalks.

One of the standout features of the Cub Cadet 721E is its powerful 208cc OHV engine, providing ample power to tackle even the heaviest snowfalls. This engine ensures reliable starts, thanks to the electric start option, making winter mornings a little easier for users. The machine’s friction disk drive system allows for easy speed adjustments and smooth operation over varying terrains, providing flexibility for users.

The 721E is equipped with an adjustable chute, allowing operators to change the direction of snow discharge with ease. The chute rotation lever can be operated from the control panel, enabling quick adjustments without leaving the operator's station. Additionally, the 8-inch impeller works in tandem with the chute system, facilitating an impressive throwing distance which can reach up to 30 feet.

Safety and comfort have also been prioritized in the design of the 721E. The unit features ergonomic handles with a soft-touch grip, enhancing operator comfort during prolonged use. It also integrates a headlight to illuminate the path ahead in low-light conditions, ensuring visibility during early morning or evening snow clearing sessions.

Durability is another hallmark of the Cub Cadet 721E. Its heavy-duty frame and high-impact plastic housing withstand the rigors of winter weather, while the reinforced steel auger augments its longevity. With features such as adjustable skid shoes and a powder-coated finish, this snow thrower is built to last through multiple winters.
