Anything that looks like a Husqvarna that is painted a different colour is just that .
Basically the same mower off the same line usually made with cheaper parts .
What has Husqvarna on the side is the best quality, everything else is a cheaper version.
Deeres are usually built to a higher level and are more rugged in design than most equivalent designs.
Because most things are better, they are also slightly more expensive.
Belts are a wear item like tyres on your car so get replaced as & when needed
And just like tyres some will wear them out in a season by abusing the mower and some will never replace them.
For instance we have just had the best rain in 3 years and this Autumn is abnormally hot so the grass has been growing a foot a week and seeding to boot.
I have done 15 belt replacements.
All of them was because the owners were trying to cut 8" or more off their grass in a single pass at a high speed .
Even worse 12 of these were set up for mulching so that puts an even higher load on the decks.
I used to try to educate customers but now days I rarely bother unless asked why they have gone through 2 or more belts in a season.
People are used to cars where now days the only maintenance that needs to be done is putting air in their tyres.
So because people are too dumb, lazy, stupid to maintain their mowers, the mower companies make mowers to suit them that run a few years the fall apart .
I have just finished servicing a Walker which is a top end mower. it has 27 grease points .
The Time cutter I did just before that had 2 , guess which one will still be running well in 20 years ?
Almost anything that is assembled in the USA will go at least 2 years without falling apart .
Fully imported mowers coming from China will do the same , if they actually work at all.
