How To Adjust The Throttle On Your Self Propelled Lawn Mower

Many of today’s non-commercial self-propelled mowers lack throttle control or adjustment and adjustments to one speed. Mowers are equipped with a bar attached to the handle that you press and hold to start and operate the mower. Releasing the bar turns off the mower engine. These types of self-propelled mowers also incorporate an additional bar attached to the handle to activate and deactivate the owner’s drive train. The traction cord can be adjusted to increase or decrease the response of the mower when the drive train is engaged. However, the operating cable adjustment rarely, if ever, increases or changes the engine speed. The only real adjustment on these mowers is a bracket assembly used to control the operating and traction cables to the mower handle. By loosening the bracket, you can slide the cables to or from the engine, which can increase or decrease drivetrain and / or throttle traction.

Step 1

Loosen the bracket that secures the mower cord to its handle. The bracket will be fixed with a nut and bolt, screw or knob.


Step 2

Carefully adjust the cable (s), about 1/2 inch away from the motor to increase traction, or towards the motor to decrease traction and tighten the bracket.

Step 3

Press the starter bar and start the engine. Slowly depress the drive train bar to test mower traction. If the mower is too fast or too slow, you may need to repeat the process several times to achieve the desired response.


  • Always consult the mower owner’s manual before making adjustments and testing the mower.
  • After adjusting the cables and before testing the mower for the first time, prepare for increased response from the drive chain to avoid damage or property damage.
  • Be very careful when operating a lawn mower.
  • Keep hands and feet away from the mower deck at all times during operation to avoid serious injury.
  • Wear appropriate safety equipment, such as safety glasses, work boots, respirators, and work gloves when operating a lawn mower.
Hyacinth Bean Vine 

This plant can grow 6-20 feet tall. It has large 6-inch dark green leaves with reddish purple veins and stems. When it blooms in summer, it produces sweet-smelling lavender flowers that turn into edible purple pods.

Plant the seeds in the spring 6-8 weeks after the last frost. The hyacinth bean vines will have full sun. The seeds should be placed about 6 inches apart, about 1/2 inch deep. Soak the seeds in warm water for 24-48 hours before planting. It is good for USDA zones 10 and 11.

Morning Glories  

These grow so fast that people often think of them as perennials. They are killed with any frost, but are usually replanted the following year. They can reach heights of 10 feet or more in two months. Morning glories should plant full sun after all danger of frost has passed.

Plant seeds about 1/4 to 1/2 inch deep, about 8 inches apart. For best results, lightly chop the seeds with a lime or soak them overnight before planting. They produce tubular shaped flowers in shades of purple, blue, pink or white from summer to fall.

Perennial Vines

Compared to annual vines, perennial vines are a better option when looking for a long-term solution.

Take care when planting woody vines like wisteria, trumpet vine, and climbing hydrangeas. If we plant them too close together, we can separate the wire and destroy the fence. To avoid this, place sections of sturdy wood or metal latticework in front of the wire fence if you decide to plant one of those varieties. While perennial vines generally take longer to mature than annuals, there are some fast-growing varieties that are perfect for covering chain link fences.

Boston ivy  

Also known as house ivy and Japanese ivy, Boston ivy can reach heights in excess of 30 feet. This vine is fast growing and tolerates almost all conditions in USDA zones 4-8. Its leaves are dark green and will turn bright red in the fall.

Clematis (Clematis Sp.)

Clematis grows so well that it is often called the “queen of climbers.” They produce large, showy flowers that bloom for long periods in the summer. It is capable of growing about 8 feet long in USDA zones 4-9, it affects the variety. Plant in well-worked porous soil in a sunny or specifically shaded area and water specifically.

English ivy (Hedera helix)

This vine has a classic fan-shaped leaf that grows well in partial sun or shade. It has a moderate growth rate that will grow approximately 9 feet tall. They grow best in USDA zones 3-9, and for best results be sure to use the best soil with a pH balance of about 7.2. English ivy is an evergreen tree that you should plant about 18 inches apart. Two crops of English ivy that are especially hardy are ‘Thorndale’ and ‘Bulgaria’.

Five-leaf Akebia 

Also known as the chocolate vine, it is a fast growing plant that will grow to the height of its support. It has oval leaves that start out purple before turning blue-green. It produces a purple fruit that ripens in early fall and attracts wildlife, and is deciduous in colder climates, but evergreen in warmer ones. It is hardy in USDA zones 4-8.

Passion Flowers  

Passion flowers, or passion vines, produce intricate purple, and sometimes white, flowers that turn into an aromatic fruit. It can be easily grown in USDA zones 5-9, but can be planted in cooler areas if it is sheltered in the winter. Passion flowers can grow up to 30 cakes in a single season, but they average around 10-15 cakes. They need partial or full sun and they like a lot of water.
