Look at this review i saw, posted 5 months ago: BEWARE. TO LONG FOR A LTX 1040.
DOES NOT FIT 1999 and NEWER ! SLIPS AND WILL NOT PULL INCLINES. RESULTING IN BELT DAMAGE.

And yesterday i was going up a small incline that the mower never had problems going up, it had trouble pulling itself up. I don't think i've gained that much weight! :laughing:

It only has 1 drive belt. And when i changed the belt last year everything seemed to be in working order.

It has 2 belts and they must be changed as a set.
If not the numbers you gave were wrong.
The second belt is accessed from under the battery box.
The other reason they go slow is because the sliding sheave part # 76 in the diagram is not sliding

It is called a sliding sheave, if you google it you should find some cleaver illustrations & animations showing how they work.

Visualise 2 pressed metal V pulleys.
Each pulley is two dish shapes welded or riveted together to form an internal V
Split them apart to make 4 discs weld the top of one to a tube weld the bottom of one to the top of another, drill out the center and put a bush in there that slides over the tube,
Weld the bottom to the other end of the tube.
So now you have a double pulley where the centre can go up or down.
So all the way down, the top pulley has a small running diameter and the bottom is large.
All the way up the opposite happens, smack in the middle they are the same size.

Now how you control where the sliding bit will be varies, as there are patients & royalties to be avoided.

The shape of the belts used on these is also different to a std V belt they are usually wider , shallower and have a smaller V angle.

Because the brake is on the layshaft not the mainshaft.
As such it locks the diff so one wheel can not turn faster than the other.
Thus when you corner one wheel has to skid.
