I have a Craftsman DYS 4500 and there is a nut under the left rear fender next to the tire that adjusts level. I'm still having trouble getting the deck tuned again despite my best effort with a bubble level, but that nut is definitely adjusted it.

Horse back riding originated in central Asia, most likely Mongolia in 4500 BC, there is evidence of horses being ridden sooner than this date but it is still under investigation.

1 ton = 2240 lb ~= 1016 kg ⇒ 4500 kg ~= 4500 ÷ 1016 ton ~= 4.42 tons I suspect you meant "How many tonnes are in 4500 kg?" (1 tonne is a metric ton.) 1 tonne = 1000 kg ⇒ 4500 kg = 4500 ÷ 1000 tonne = 4.5 tonne. 1 kilogram = 2.20462262 pounds
