All good points mentioned previously;
The major issue with any cylinder is ROD BENDING which is a dirty wood of the first order in a hydraulic repair shop.
AS 99% of any hydraulic cylinders purchased today do not have stop tubes to strengthen the rod and barrel in its work, it is a nasty expensive issue for the end user.
The rule of thumb is one inch of stop tube for every foot of extended length adding an inch of tube for the odd measurement that is left if any.
You only lose a very small distance in stroke length and with dry to moist materials thats not an issue at any time.
With wet muck like snow or mine ore is an issue for an ejecto bucket that forces the material out of the bucket (used for situations where a bucket can not be raised sufficiently to tilt the bucket to dump it).
The stuffing box and stuffing box bushing are the main supporters of the cylinder rod and the leaky wiper seal is the very first indicator that the rod is bent as the stuffing box/packing gland/bronze bushing has also suffered damage beyond repair.
The maufacturers of these front end loaders take none of the above or the end users digging with the bucket in consolidated material (the dirt and clay under yor feet that has been packed down by rainfall) into account and the end user has cylinders that fail prematurely from missuse.

I have a thread here someplace on one of the forums about stop tubes in complete detail.
