Assembly Instructions

It is very important that your new 7822 High Speed 
Landoll () be properly assembled, adjusted and 
lubricated before use. Illustrations in this section show 
proper assembly procedures. Remove paint from grease 
fittings. Replace any grease fittings that are damaged or 
missing. Be sure to return screws, clips, etc., to their 
original locations.

To ensure alignment of assemblies, 

leave the nuts 

loose until completion

 of final assembly. Use lock 

washers or flat washers as specified. Spread all cotter 
pins.

After completion of final assembly, tighten all nuts 
evenly

 to prevent misalignment, distortion or binding. 

Tighten all screws and nuts to the recommended torques 
shown in

 

“General Torque Specifications (rev. 4/97)” 

on page 2-2

DANGER

WARNING

DANGER

CAUTION

Unloading the HSL and 
Final Assembly

I

n most cases the 7822 has come to you with the main 

wheels and tires shipped loose due to shipping width, 
restrictions.

1.

Install the main wheels and tires to the hitch 
rockshaft hubs. 

See Figure 3-2

2.

Due to the being a towed implement the tire tread is 
typically installed opposite of that of a tread where 
power would be applied through it.

 

NOTE

There is a protruding step on the hub pilot. The wheel 
center plate must fit over the hub pilot and then bottom 
out against the hub flange. Failure to get the wheel 
properly positioned against the hub face will cause the 
wheel to loosen and cause damage to the hub and/or 
wheel. 

3.

With the tire and wheel assembly correctly positioned 
against the hub, begin to tighten the flange nuts 
sequentially as shown below. 

Figure 3-1:  Lug Nut Tightening Sequence

4.

Re-check the positioning of the wheel relative to the 
hub and proceed by tightening the lug nut assemblies 
sequentially to 450 to 500 foot pounds.

Disc blades are extremely sharp. Exercise 
extreme care when working on or near disc 
blades. Do not allow discs to roll over or fall onto 
any bodily part. Do not allow wrenches to slip 
when working near disc blades. Never push 
wrenches toward disc blades. Do not climb over 
machine above disc blades. Failure to stay clear 
of disc blade edges can cause serious personal 
injury or death.

Do not attempt to lift heavy parts (such as the 
frame, disc gangs, rockshaft, and pull hitch) 
manually. Use a hoist or a fork lift to move these 
parts into position.

To prevent accidental lowering:

All hydraulically elevated equipment must be 
locked out using the cylinder lockouts.

Lower equipment to the ground while 
servicing or when it is idle.

Failure to take measures to prevent accidental 
lowering may result in serious personal injury or 
death.

Be sure to bleed the hydraulic system of all air in 
lines after installation. Failure to bleed the system 
of all air can result in improper machine 
operation.
