Towing Safety
Slopes and Uneven Terrain
Operating the Chipper (not available on Premier Machines)
In addition to towing the DR LEAF and LAWN VACUUM with your Lawn
Tractor, and using it as a vacuum, the system also allows you to chip sticks and
limbs up to 2" in diameter.
1. Start the Engine in accordance with “Starting and Stopping” on page 18.
2. To process branches; feed them into the Chipper Hopper opening (Figure
32).
3. As the chipped branch shortens, finish chipping it by pushing the stub down
the Hopper with the next branch to be chipped.


Never operate your machine on slopes greater than 15 degrees (Figure
31). When operating the DR Leaf and Lawn Vacuum over uneven terrain
and slopes, use extreme caution to not tip over the machine. Move
slowly, especially with a full load, if the ground has ruts, bumps, and other
depressions.
 Do not use the DR Leaf and Lawn Vacuum on slopes greater than 15
degrees. Doing so could result in serious injury or damage to your
machine.
 On a slope, a heavy load will tend to shift. When using your DR Leaf and
Lawn Vacuum, keep in mind that loads tend to shift to the downhill side
of the collector box. The higher and heavier the load, the greater the
chance you may tip over the machine.
 Travel up and down slopes and avoid going across slopes. This is the
same recommendation for mowing with your lawn tractor alone.

Watch out for low branches, overhangs, and guy wires that may catch on top of the collector box.
 Never allow anyone to ride in or on the DR Leaf and Lawn Vacuum.

Obey local, state, and federal regulations when you tow the DR leaf and lawn vacuum across public roads and highways.

Use caution when backing up your lawn tractor or trying to make tight turns going forward with the DR Leaf and Lawn
Vacuum attached. Trying to turn too sharply can cause damage to the hitch and/or the lawn tractor if you hit an obstacle.
Go slowly in areas where tight turns are necessary. Straighten out the system before attempting to back up.

To prevent damage to your chipper, feed only wood up to 2" in diameter
into the chipper hopper.
 Never use your hand to push the remaining wood stub down into the
chipper hopper or try to remove a lodged piece of wood with the engine
running.
