Section 2: Dealer Preparation
Machines shipped by truck have Windrower assembly removed. Main frame and
rock wheel frame are secured by bolts and clamps. Windrower assembly should be
bolted to frame and clamps removed. Two transport pins have been provided in
upright rock wheel frame guides. Lock pins may be used to keep wheel in raised
position for extended periods of time, or in case of hydraulic failure when
transporting long distances. Be sure to remove any pins from transport position to
prevent damage to machine while testing hydraulic controls.
2.1 Assembly
To assemble the ROCK-EZE for operation, follow the instructions on pages 10-16,
steps 1-10.
STEP 1.
Begin assembly with machine on a level area. Hook machine to tractor drawbar.
All assembly and adjustment must be done with drawbar height at 16 inches (plus
or minus 1 inch) from ground level to top of drawbar
STEP 2.
Attach hoses to proper hydraulic outlets on tractor (illustrations pages 19, 20, and
21). For easy assembly of Windrower rotor (Step 3) raise rock box to full height.
Place safety block (provided with machine) on cylinder.
STEP 3.
Assemble windrower and bearings as shown on page 5. Slide end of Windrower
rotor with bearing attached under machine towards rock wheel. Disconnect hose
(A), on the facing page, at zerk fittings. Tighten elbow (B) into bearing with elbow
pointing upward. Connect hose to elbow (B) slide rotor and bearing assembly into
carrier bracket (D). Tighten bearing bolts securely. Reconnect hose (A) to zerk
fitting. Install machine bushing and 7 Ga. washer on Windrower. See facing page.
Bolt bearing shield (E) in place.

9H-106 ROCK-EZE OPERATING INSTRUCTIONS
STEP 6.
Match (4) holes in bearing bracket (K), illustrated on facing page, to (4) holes in
hanger support (R). DO NOT tighten bolts at this time. To get proper chain and
sprocket alignment, Windrower rotor and drive chain case must be 90° to each
other. This can be done by placing one edge of a carpenters square parallel to chain
case and the other edge parallel to Windrower rotor illustrated on page 7. Proper
angle can be obtained by sliding hanger ® in or out on hanger tube (P). Once
proper alignment has been made, slide two pipe clamps (V) , illustrated on facing
page, against caster wheel hinge support and tighten bolts.
STEP 7.
Locate 20 tooth sprocket, 3/8" square key, machine bushings, and cotter pin as
illustrated on Page 7. Tighten two (2) Allen screws in sprocket hub, locking
sprocket to shaft, and locking square key in key slot. Check sprocket alignment by
placing aligning tool (found in chain case) along one edge of each sprocket as
illustrated on Page 7. Due to oversize holes in hanger ® illustrated on the facing
page, and bearing bracket (K) alignment of 20 tooth sprocket can be made by
rotating these brackets slightly. Tighten all bolts in hanger and support brackets.
Sprocket and chain alignment are important: recheck alignment before installing
chain.
STEP 8.
Loosen (4) four nuts holding flange bearing and adjuster to chain case. Install
chain. Adjust to proper tension (no sag between sprockets). Tighten bearing and
adjuster nuts. Install chain case cover, being careful not to over tighten the center
bolt causing cover to bend.
Remove plastic plug and fill approximately 1" below bottom of plug hole, use 90
weight oil. Install plug. Drive chain tension can also be checked through plug hole.
STEP 9.
Locate tumbling shaft (S), illustrated on the facing page. Install end with 5/16" key
slot on hydraulic motor. Tighten Allen screws securely. Mount shield (J) on brace
tube (1) Page 6. Tighten bolts securely.
Attach chain linkage (T) and adjusting rod (U) as illustrated on the facing page.
Leave enough slack in bolts at hinge points so they can swivel when Windrower
rotor is raised and lowered. Hole choice in upper end of chain linkage is used to get
desired Windrower rotor height when in raised position.
STEP 10.
Place 1/4" hair pin in bottom hole of adjusting rod (U) under loop on caster wheel
bracket. This carries wheel assembly when Windrower is in raised position. Top
hair pin is placed in hole giving desired Windrower rotor height while in operation.
Insert hair pins in direction shown on the facing page, to avoid lift arm contact.
Assembly of your DURATECH ROCK-EZE Model 106 is now complete. Recheck
all bolts to make sure they are tight and grease all fittings. Also be sure all moving
joints are free to allow rotor to float over uneven terrain.

2.2 ADJUSTMENTS
Preliminary adjustments are made in the factory and during set up. Some adjusting
may be necessary in field.
Machine was designed for a drawbar height of 16".
Depth of Windrower inner end nearest rock wheel is adjustable in 1" increments as
shown at (H) on Page 5. of assembly instructions. Outer end is adjusted by
changing upper hair pin in rod (U) Page 8, attached to chain drive case. Lower hair
pin is designed to carry gauge wheel during transport.
Chain adjustment on outer end of Windrower is provided to level Windrower in
raised position (T) Page 8.
Adjustments on Y bracket at front of main frame is described in step 3, page 4, and
shown at (F) on Page 8, of assembly instructions.
There are three (3) adjustments on rock plate: (Not Shown).
1. One at rear of rock wheel which allows minimum clearance between rear of
rock plate and ring on rock wheel.
2. One at front of rock box to allow clearance between front of rock plate and
octagon hub of rock wheel.
3. One near lower portion of rock plate to relieve pressure against carrier bracket
plate shown at (D) on Page 8, on assembly instructions.
The clearance of the kicker rotor stripper rubber is important. Bolt holes in rubber
are slotted so it may be adjusted up or down where it bolts to the rock box. Rubber
should be clear of square bars on rotor. Rubber may be turned top side down when
a new edge is required.

11H-106 ROCK-EZE OPERATING INSTRUCTIONS
Section 3: Introduction
You have chosen a machine that will windrow and pick your rocks in one
operation.
There are some important points to remember in the operation of your 106 ROCK-
EZE.
1. The Tractor used to power your rockpicker should have an adequate hydraulic
system. A minimum of 12 G.P.M., and 1500 P.S.I. is required at the outlets
where hoses from rockpicker are plugged into tractor.
If the hydraulic system is not adequate, system will heat causing rotors to
slow down and possibly stop. Some older tractors do not have coolers in their
hydraulic system. Some have small oil reserves. Either case will allow fluid
to heat rapidly.
When rotors operate properly, the rock box will fill nearly level from side to
side. If box fills only on the side nearest the kicker rotor, R.P.M. should be
checked with tachometer at rear of kicker rotor. Rotor should turn a minimum
of 500 R.P.M. Any less will allow rocks to wedge in kicker rotor.
In cases when specifications are adequate, but rotors tend to operate too slow,
tractors hydraulic system should be checked for G.P.M. and P.S.I., as systems
tend to wear and not meet manufacturers specifications.
2. Conditions of terrain to be picked are important. Soil should be loose and free
of trash. Terrain with ridges does not allow windrower to gather small stones.
This machine was not designed to dig rocks. In most cases, windrower rotor
should be allowed to skim approximately 1" of loose topsoil.
Trash gathered in rock wheel does not allow small rocks to tumble free and
the dirt to fall through bars.

3.1 HYDRAULIC SPECIFICATIONS
Any tractor having an adequate system (minimum of 12 G.P.M. and 1500 P.S.I. at
tractor outlets) may be used on this rockpicker. The ROCK-EZE comes standard
with hoses to accommodate triple outlets from the tractor. Optional kits are
available for tractor with single or double outlets.
3.2 OPTIONAL EQUIPMENT
1. Kits for equipment with single or double hydraulic outlets.
2. Loose surface rocks may be picked from level soil which is not tilled, such as
pasture or stubble ground. Some rocks will roll out in front of the rock wheel.
An optional drag plate is available to stop these rocks and direct them into the
wheel.
