How to Fix a Rototiller

As any gardener will tell you, the rototiller is one of the best inventions since the wheel. But it will break from time to time, and you'll find yourself needing to replace the tines. Here is a simple guide on how to do just that and get back to gardening as soon as possible.

Things You'll Need

• Replacement tines
• Hex-head, flat-head or Phillips-head screwdriver (depending on tiller model)

Instructions

1. Put the tiller on a level surface, turn it off and make sure it is in the “park” gear.

2. Prop the tiller up on blocks, boards or another surface high enough to raise the tines completely off the ground.

3. Decide which side you will replace first and lay out the correct tine for that side. There is a left tine and a right tine, so make sure you get and put the correct tine for the correct side.

4. Remove the old tine from the side you are working on using the proper screwdriver. Your installation/instruction manual will have pictures of the screws that are on your particular tiller. If you look at that first, you will know what type of screwdriver you will need.

5. Clean the area around the tine housing. This will ensure that the new tines fit properly and function more efficiently.

6. Fit the new tine (make sure it is the correct tine for the side being worked on) onto the tine housing and tighten the screws securely.

7. Repeat for the other tine.

Tips & Warnings

• Only remove and replace one tine at a time if you are replacing both. You will avoid the possibility of getting the tines mixed up.

• Make sure the material supporting the tiller so that the tines are off the ground is sturdy and secure. Serious injury to you or irreparable damage to the machine could occur if the tiller should slip off the supports.

• Take care when bleeding the hydraulic lines if this must be done before replacing the tines. Hydraulic fluid is under pressure and can get into and under skin without being noticed. If this occurs, medical help must be sought immediately.
