OPERATION AND MAINTENANCE
Tractor Preparation
The 7550 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.
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.
VT Plus Preparation
Figure 4-1: Disc Scraper to Disc Blade
1. Prior to operating the 7550 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 or
“Standard Specifications”
on page 2-1 .
5. Check disc scrapers for proper adjustment to the disc
blade
( See Figure 4-1. )
6. Lubricate the machine as shown ( See Figure 4-23. )
Attaching to the Tractor
1. Align the tractor drawbar with the machine. Raise or
lower the hitch, as needed, using the swivel jack.
Attach the unit with proper size hitch pin.
2. Always place the swivel jack on the interior mount
before setting the machine in motion.
3. Clean all hydraulic couplings and attach to the
tractor.
4. Attach safety chain to tractor allowing plenty of
movement for turning both directions. The safety
chain should latch securely to prevent it coming
loose.
5. Plug in the 7-pin connector for the lights.
a. The tractor should have a good clean receptacle,
free of dirt and corrosion.
b. Make sure the 7-pin connector is inserted all the
way in, and allows the cover to latch over the
keyway to secure it in place.
NOTE
The lighting system requires a good ground connection
and if the lights do not seem to work right check the
installation of the 7-pin connector and the condition of the
pins.
