PREPARATION  
1. Safety instructions are important! Read this manual and the  
tractor’s Operator’s Manual; follow all safety rules and safety  
label information. (Replacement labels are available through  
your Cub Cadet Yanmar dealer.) Failure to follow instructions  
or safety rules can result in serious injury or death.  
1. Check that all hardware is tight and properly installed. Always  
tighten to torque specifications as instructed in this manual.  
2. Air in hydraulic systems can cause erratic operation and  
allows loads or equipment components to drop unexpectedly.  
3. Before operating or allowing anyone to approach the equip-  
ment, purge any air in the system by operating all hydraulic  
functions several times after connecting equipment, connect-  
ing hoses, or doing any hydraulic maintenance.  
2. If you do not understand any part of this manual and need  
assistance, contact your Cub Cadet Yanmar dealer.  
3. Know your controls and how to stop engine and attachment  
quickly in an emergency.  
4. After connecting hoses, check that all control lever positions  
function as Instructed in this Operator’s Manual. Do not oper-  
ate until control lever and equipment movements are correct.  
4. Operators must be instructed in and be capable of the safe  
operation of the equipment, its attachments and all controls.  
Do not allow anyone to operate this equipment without proper  
instructions.  
5. Protective sleeves must be over hydraulic hoses and securely  
fastened onto metal hose fittings as described in this manual.  
Replace if damaged or if protective sleeve is not properly  
positioned or secured.  
5. Keep hands and body away from pressurized lines. Use paper  
or cardboard, not body parts to check for leaks. Wear safety  
goggles. Hydraulic fluid under pressure can easily penetrate  
skin and will cause serious injury or death.  
6. Make sure all hydraulic hoses, fittings and valves are in good  
condition and not leaking before starting power unit or using  
equipment. Check and route hoses carefully to prevent dam-  
age. Hoses must not be twisted, bent sharply, kinked, frayed,  
pinched, or come into contact with any moving parts. Operate  
moveable components through full operational range to check  
clearances. Replace any damaged hoses immediately.  
6. Make sure that all operating and service personnel know  
that in the event hydraulic fluid penetrates skin, it must be  
surgically removed as soon as possible by a doctor familiar  
with this form of injury, or gangrene, serious injury or death  
will result. CONTACT A PHYSICIAN IMMEDIATELY IF FLUID  
ENTERS SKIN OR EYES. DO NOT DELAY.  
7. Always wear relatively tight and belted clothing to avoid  
entanglement in moving parts. Wear sturdy, rough-soled work  
shoes and protective equipment for eyes, hair, hands, hearing  
and head.  
7. Do not allow children or untrained persons to operate equip-  
ment.  
8. Avoid injury or death. Never work under a raised loader.  
Always lower loader to the ground with bucket or loader  
attachment in full roll-back position. Operate valve levers  
to release any hydraulic pressure. If loader obstructs tractor  
maintenance, loader must be removed from tractor.  
insTallaTion  
1. During installation, the tractor engine should be off, the key  
removed and the parking brake engaged.  
2. Do not disconnect hydraulic lines until attachments are  
removed or lowered to the ground and system pressure is re-  
leased by operating valve levers. Never operate any hydraulic  
cylinders during any phase of the installation process.  
9. Do not modify or alter or permit anyone else to modify or alter  
the equipment or any of its components in any way.

the boom cylinders. Cut and remove the ties if present.  
Stop the tractor engine and set the tractor’s parking brake  
before leaving the operator’s seat. Proceed to “Installing the  
Front Loader” in this section.  
iMPOrTanT: Re-start the tractor and perform the hydraulic test  
described below in Checking implement Control Lever Opera-  
tionto assure that all implement control lever movements result  
in the loader movements described. if loader movements do not  
respond correctly, turn the tractor’s engine off, set the parking  
brake and recheck all hydraulic connections as described above.  
loader control movements must be correct before proceeding.  
Pre-Charging Cylinders for initial installation  
If an overhead lift is not available, the front loader cylinders can be  
used to position the loader for installation. To position the loader,  
proceed as follows:  
Start the tractor and carefully drive the tractor to position it  
along the right side of the front loader, facing in the opposite  
direction of the loader.  
iMPOrTanT: if you were unable to connect the pistons of the  
two bucket cylinders to the bucket rear mounting brackets as  
instructed earlier, use the tractor’s implement control lever to  
extend the pistons as needed and connect the cylinders now.  
iMPOrTanT: Stop the tractor engine. Set the tractor’s parking  
brake before leaving the operator’s seat.  
Remove the four protective caps from the male couplers at  
the free ends of the hydraulic hoses.  
Warning: Use extreme caution when perform-  
ing the loader boom cylinder charging procedure.  
Locate the color coded protective plugs in the female  
hydraulic couplers on the lower right side of the tractor, just in  
front of the right/rear tire. Refer to Figure 8.  
nOTe: For packaging purposes the two boom cylinders are  
fully collapsed. this results in the loader masts being positioned  
beyond their normal vertical position, which causes the loader’s  
center of gravity to be shifted rearward of normal. Consequently  
the loader hitch arms may not pivot downward when initially  
extending the boom cylinders pistons. When performing the  
initial priming of the boom cylinders, it will be necessary to apply  
downward force on the front of the bucket (e.g.; placing weight on  
bucket shave plate; an assistant applying downward pressure on  
the bucket) to pivot the hitch arms downward and raise the loader  
masts.  
Using the color coded plugs and matching color coded  
washers on the loader hoses to guide you, remove the plugs  
and connect each loader hose to the appropriate hydraulic  
coupler. Refer to Figure 8.  
nOTe: if for any reason the color coded plugs of the outlets  
and/or caps and washers of the hoses are unavailable or incor-  
rect, follow the routing of each hydraulic hose/tube to the loader  
cylinders to determine the loader connection of each hydraulic  
line. Use the following information to determine the appropriate  
hose to hydraulic outlet connection. Working from the right side of  
the tractor, facing the hydraulic outlets, proceed as follows:  
While observing the hoses to ensure they do not become  
pinched or stretched, slowly and carefully move the imple-  
ment control lever rearward to extent the boom cylinders. The  
loader hitch arms should pivot downward toward the ground  
and raise the bottoms of the masts.  
Outlet #1 (lower left) - connect the hydraulic line from the piston  
ends of the bucket cylinders (roll back bucket).  
Outlet #2 (upper left) - connect the hydraulic line from the cylinder  
body ends of the bucket cylinders (dump bucket).

Continue to carefully extend the boom cylinders (and roll back  
the bucket if necessary) until the center points of the support  
plates on the bottom of the loader hitch bracket at the front of  
loader hitch arms are resting on the ground (Refer to Figure  
13). The support plates and bucket should be supporting the  
loader and the bottom of each mast should now be higher  
than the tubular bars of the loader mounts.  
By SLIGHTLY moving the implement control lever in the vari-  
ous directions, check that all control lever positions correctly  
operate the loader movements as indicated in Figure 10.  
iMPOrTanT: Move the control lever only slightly.  
Stop the tractor engine and engage the parking brake.  
Disconnect the loader hoses from the hydraulic couplers  
by pushing inward the locking collars of the tractor’s female  
hydraulic couplers.

initial installation of Loader on Tractor  
The control lever will be used to aid in mounting the loader to the  
tractor. To complete the initial installation, proceed as follows:  
Warning: always comply with all Safety rules  
before starting the tractor.  
nOTe: if an overhead lift was used and the pistons of the two  
bucket cylinders have not been connected to the bucket rear  
mounting brackets as instructed earlier, use the tractor’s imple-  
ment control lever to extend the pistons as needed to connect the  
cylinders now.  
Start the tractor’s engine and operate at a low/safe RPM.  
Shift the tractor’s hydraulic lock lever to the center position.  
See Figure 9 and refer to the tractor Operator’s Manual.  
• If an overhead lift was used to position the loader, lower the  
lift to make certain it is no longer supporting the loader. Do  
not remove the attaching devices yet. Re-start the tractor  
engine.  
While observing the base of the masts, slowly push the imple-  
ment control lever forward to lower the boom, and to the right

added to your tires, and for any special maintenance  
instructions after the procedure is performed.  
pre-operaTion CHeCk lisT  
(operaTor’s responsibiliTY)  
The operator should perform the following check list  
before operating loader.  
using iMpleMenT ConTrol lever  
The tractor’s implement control lever is located at the  
front/right corner of the operator’s seat and is used  
to control the movements of the loader. All implement  
control lever movements should result in the loader  
movements described below. If loader movements  
do not respond correctly, turn the tractor’s engine  
off, set the parking brake and recheck all hydraulic  
connections as described in “Pre-Charging Cylinders  
for Initial Installation” in the “Initial Installation” section  
earlier in this manual.  
Review and follow all safety rules and safety labels  
on pages 3 through 5.  
Check that all safety labels are installed and in  
good condition. Replace if damaged.  
Check that equipment is properly and securely  
attached to tractor, and that the bucket is securely  
attached to the loader using the pins and retain-  
ing hardware supplied. Check that all hardware  
(including all screws, nuts and pins) are properly  
installed and secured.  
While seated in the operator’s seat of the tractor,  
use the implement control lever to control the loader  
movements as follows (Refer to Figure 14):  
Check all lubrication points and grease as in-  
structed on Page 23 of this manual.  
Check that all hydraulic hoses and fittings are in  
good condition and not leaking before starting  
tractor. Check that hoses are not twisted, bent  
sharply, kinked, frayed or pulled tight. Replace any  
damaged hoses immediately.  
Move the control lever rearward to raise the loader  
boom.  
Move the control lever to the right to dump bucket.  
Move the control lever to the left to roll back  
bucket.  
Make sure tractor ROPS and seat belt are in good  
condition. Never operate the loader without the  
tractor ROPS installed and in the up position, and  
the seat belt securely fastened around you lap.  
Move the control lever rearward and to the right to  
raise the boom and dump the bucket.  
Move the control lever rearward and to the left to  
raise the boom and roll back the bucket.  
Do NOT allow riders.  
Move the control lever forward to lower the loader  
boom.  
TraCTor ballasT  
Move the control lever forward and to the right to  
lower the boom and dump the bucket.  
If installing only the front loader (without the backhoe),  
weight must be added to the rear of the tractor. The  
most common methods of adding weight are mounting  
the rear weight box (Mod. No. 59A40013727) and/or  
filling the rear wheels with liquid ballast.  
Move the control lever forward and to the left to  
lower the boom and roll back the bucket.  
Move the control lever fully forward past the  
detent to place the boom in the float position. The  
boom will float and allow the bucket will follow the  
contour of the ground. The bucket control cannot  
be used when the lever is in the float position.  
rear Weight Box  
Requires a minimum total weight of 500 pounds in  
a rear weight box, with the center of gravity of the  
weight positioned approximately 41" from the center  
of rear axle and 20" above ground. If the weight box  
is positioned closer to the rear axle or carried higher,  
additional weight must be added to effectively counter-  
balance the front loader.

noTe: Do not be concerned if the bucket is not  
completely filled during each pass. Maximum produc-  
tivity is determined by the amount of material loaded  
in a given period of time. Time is lost if two or more  
attempts are made to fill the bucket on each pass.  
operaTing THe loader  
Warning: Do not operate unless all control lever  
positions function as instructed in Figure 10.  
The loader should be operated with the tractor engine  
running at a safe RPM. Excessive speeds are danger-  
ous, and may cause bucket spillage and unnecessary  
strain on the tractor and loader.  
Lifting the Load  
When lifting the load, keep the bucket positioned to  
avoid spillage. See Figure 17.  
iMporTanT: To prevent possible damage to the  
tractor transmission, engage the 4WD only when  
additional traction is needed while operating in loose  
soil or on slippery surfaces, or when descending a  
slope. Disengage the 4WD when operating on firm,  
flat surfaces or when operating at high speeds. Refer  
to the tractor operator’s manual for instructions on  
using the 4WD feature.  
Approach and enter the pile with a level bucket.  
See Figure 15.  
figure 17  
warning: do not attempt to lift bucket  
loads in excess of the loader capacity.  
figure 15  
The lift and rollback of the bucket will increase effi-  
ciency because maintaining a level bucket throughout  
the lifting cycle resists bucket lift and increases  
breakaway effort. See Figure 16.  
iMporTanT: If you should discover that your tractor  
requires increased stability for a particular application,  
contact your Cub Cadet Yanmar dealer about ad-  
ditional weighting for the rear of the tractor.  
Correct  
Carrying the Load  
Position the bucket below the level of the tractor hood  
for maximum stability and visibility, whether the bucket  
is loaded or empty. See Figure 18.  
NOT Correct  
figure 18  
figure 16  
18  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Use extreme care when operating the loader on a  
slope; keep the bucket as low as possible. This keeps  
the bucket and tractor center of gravity low and will  
provide maximum tractor stability. See Figure 19.  
Dumping the Bucket  
Lift the bucket high enough to clear the side of the  
vehicle. Move the tractor in as close as possible, then  
dump the bucket. See Figure 20.  
Correct  
NOT Correct  
figure 20  
figure 19  
Lowering the Bucket  
After the bucket is dumped, back away from the  
vehicle while lowering and rolling back the bucket.  
warning: avoid injury or death from  
rollover accidents:  
Move and turn tractor at low speeds.  
Watch for hidden hazards such as holes, ditches,  
and other obstructions which may cause tractor  
and loader to tip over.  
Lower  
Carry loads close to the ground to aid visibility and  
lower center of gravity for improved stability.  
Balance loads so weight is evenly distributed and  
load is stable.  
Be extra careful when operating on a slope.  
Do not operate on steep slopes.  
Do not stop, start or change directions suddenly on  
slopes.  
Tractor seat belt and Roll-Over Protective Structure  
(ROPS) must be present. Keep seat belt securely  
fastened and keep ROPS systems in “up” position  
at all times.  
Roll Back  
iMporTanT: When transporting the load, keep the  
bucket as low as possible to avoid tipping, in case a  
wheel drops in a rut. Refer to Figure 19.  
figure 21

Operating with a Float Control  
Peeling and Scraping  
During hard surface operation, keep the bucket level  
and put the lift control in the float position to permit  
the bucket to float on the working surface. If hydraulic  
down pressure is exerted on the bucket, it will wear  
faster than normal. See Figure 22.  
Use a slight bucket angle, travel forward, and hold  
the lift control forward to start the cut. Make a five- to  
eight-inch angle cut and break-out cleanly. See Figure  
24.  
Surface Material  
figure 22  
figure 24  
noTe: The float will also prevent the mixing of surface  
material with stockpile material. The float position will  
reduce the chance of surface gouging when removing  
snow or other material.  
With the bucket level, start a cut at the notch approxi-  
mately four inches deep. Hold the depth by feathering  
the bucket control to adjust the cutting lip up or down.  
When the front tires enter the notch, adjust the lift  
cylinder to maintain proper depth. See Figure 25.  
Loading from a Bank  
Exercise caution when undercutting high banks. Dirt  
slides can be dangerous. Load from as low as possi-  
ble for maximum efficiency. Loader lift and break-away  
capacity diminish as loading height is increased.  
It’s important to keep the bucket level when approach-  
ing a bank or pile. This will help prevent gouging in the  
work area. See Figure 23.  
figure 25  
Make additional passes until the desired depth is  
reached. During each pass, only use the bucket  
control while at working depth. This will allow you to  
concentrate on controlling the bucket angle to main-  
tain a precise cut.

Loading Low Trucks or Spreaders from a Pile  
Backblading  
Position the bucket at an angle of less than 45º and  
backup slowly. See Figure 28  
For easier loading, minimize the angle of turn and  
length of run between pile and spreader. See Figure  
26.  
Backgrading or backblading with bucket tilted too far  
will result in damage to tilt cylinders and void warranty.  
See Figure 28.  
Correct  
NOT Correct  
figure 26  
Backgrading  
Backgrade occasionally with a loaded bucket to keep  
the working surface free of ruts and holes. Also, hold  
the control lever forward so the full weight of the  
bucket is scraping the ground. Use the heel of the  
bucket. See Figure 27.

Backfilling  
Handling Objects  
Approach the pile with a flat bucket. Do not use  
the bucket in the dump position for bulldozing. This  
method will impose severe shock loadings on the  
dump linkage, the tilt cylinder, and the tractor. Refer to  
Figure 29.  
warning: avoid injury or death from  
falling objects. This loader is not  
equipped with any method to prevent  
objects such as round bales, posts,  
logs, etc. from rolling back onto opera-  
tor.  
Leave dirt in the bucket because dumping on each  
pass wastes time.  
Operate at right angles to the ditch. Take as big  
a bite as the tractor can handle without lugging  
down.  
warning: do not carry large objects  
that can fall out of loader bucket into  
operator zone.  
Leave dirt which drifts over the side of the bucket  
for final clean-up.  
warning: never lift loader higher than  
necessary to clear the ground when  
moving.  
Pile dirt on the high side for easier backfilling on a  
slope.
