Hi Steve,

I was hoping your first post at the top of the page, the part numbers may of been
correct but that would be.
Drive Belt - 532140294 that you had listed and is (1/2" x 82") and your current measurement is
2210mm is approximately 83.07 inches.but the old belt you say is 2240 mm which is 88.19 inches

Deck Belt - 532144959 at top of page is 95 inch V belt and you have 2240 mm
for that which is 88.19 inches.

All the Husqvarna belts I look up are half inch wide .

I can't find any manuals or specs online for a 1989 Husqvarna ride on,
the closest I found is 1995 and those belts are not listed for fitting earlier models
so I wouldn't go on that manual for part numbers for the V belts.

The only part numbers I found online that had the same length belts for
the drive belt and cutter deck belt were the Husqvarna 954140005K 88 inches drive belt Husqvarna954140005F deck belt 88 inches deck belt

Some sellers online said if you cant find your model numbers for the
mower on their description of the V belts you should email them all
the mowers details and they will look up the correct part numbers.

Maybe someone else will have the correct manual for part numbers here.

Cheers
Max
