Locke GT-126 Manuel D’Utilisation

There are 4 pressure lubrication points on the mower. 
All are zerk type grease fittings. Use a quality light 
grease at these points. The bronze clutch collars each 
have a grease fitting. These are located at the front of 
the tractor on the left and right sides underneath the 
main guard. Lubricate with 1 or 2 shots of grease every 
10 hours of operation. The caster post has a fitting. It is 
located just above the attachment point of the caster 
wheel. Lubricate this every 20 hours of operation. The 
last fitting is located on the differential, between the 
rolls or tires depending on how your mower is 
equipped. Lubricate this every 100 hours of operation.  
Keep all chains well lubricated with a thin lubrication 
oil. It is best to lubricate them after each mowing or 
every 4 hours of use. This prevents rusting while stand-
ing idle and allows the oil to penetrate to the pin and 
bearings by capillary action.  When a chain is operated 
without lubricant, the chain will wear prematurely and 
the elongated chain will in turn wear the sprockets to 
conform to the pitch of the chain. 
Worn chains make expensive repairs because the 
sprockets as well as the chains must be replaced. 
Proper lubrication will give you many years of trouble-
free service. 
 

When cutting is finished, clean the machine. It is much 
easier to clean now than later. This is a good time to oil 
the chains and lubricate the mower, allowing the oil to 
penetrate and the grease to flush out grit. If a high 
pressure wash down is used it is imperative to lubricate 
thoroughly after cleaning. 
Inspect the mower for any loose or worn components 
and replace if necessary. If you do not understand the 
mechanics of the mower, contact your dealer for ser-
vice.

 

The operating and maintenance instructions for the 
Honda engine are explained in a manual furnished by 
the engine manufacturer which is included in the infor-
mation packet you received with your mower.

 

All parts that constantly rotate are carried on ball bear-
ings. The reel, clutch shaft, height roller and roller axle 
have permanently sealed bearings. The reel chain 
idlers and caster wheel are carried on semi-precision 
bearings and may require lubrication. Pivot points such  

The clutches are dry multi disc type, limited load, 
enclosed and non adjustable, using molded friction 
discs, hardened dogs and cone and bronze shift-
ing collar. 

 

as reel link arms, reel bearing housings, etc. have 
sintered bronze bushings. 

The tractor rolls are in reality hard rubber tires. They 
are mounted on a single axle which drives them 
through differential gears. The differential is com-
posed of two steel bevel gears and two steel pinions 
with hardened teeth, fully enclosed and packed in 
grease. 
 

On occasion it is necessary that slack be taken up 
on the tractor chain. Tension should be adjusted so 
that there is a slight movement by hand pressure. 
Excessive tension will result in loss of power and  
premature wear on components. To adjust the trac-
tor chain, loosen the bolt on the chain adjuster and 
push on the plastic block until the desired tension is 
achieved. (See figure below) Tighten the bolt to se-
cure the tensioner block. When the chain has elon-
gated to the point of using all of the adjustment, it 
will be necessary to take out a link of chain.
