OPERATION AND MAINTENANCE

Tractor Preparation

The Landoll 7431 VT Plus is designed to be pulled by

tractor equipped with a double lip or clevis type hitch. If

your tractor is not equipped as such, you need to

purchase the hitch from your local tractor dealer. If your

VT Plus is equipped with the clevis option, this should be

removed. The clevis option is only for transport use.

Before attaching the VT Plus, prepare the tractor as

follows:

1. Inflate the rear tractor tires equally and add ballast

according to the tractor operator’s manual.

2. Lock the tractor drawbar in the center position.

Figure 4-1: Disc Scraper to Disc Blade

1. Prior to operating the 7431 VT Plus, inspect it

thoroughly for good operating condition.

2. Replace worn or missing parts.

3. When the machine is new, check the bolt tightness

after a few hours of operation. Tighten any loose nuts

or bolts. Check the lift wheel lug bolts daily.

4. Check the lift wheel tire inflation. Inflate all tires

equally to avoid side draft. Follow the tire

manufacturer’s recommended pressures listed on

the sidewall of the tires.

5. Check disc scrapers for proper adjustment to the disc

blade (See Figure 4-1.)

6. Lubricate the machine as shown in “Lubrication

Maintenance” on page 4-21 (See Figure 4-22.)
