Looking underneath the mower on top of the deck there should be a flat metal arm with a flat faced pulley on the end. This pulley pushes against the belt that drives the mower deck . The spring should be hooked on that arm and pulled tight over to a place on the deck and this is what keeps the belt tight enough to turn the blades when you engage the pto switch. My recommendations to put this back on is to remove the belt pulley cover on the deck right side roll the belt off at that pulley giving you a bunch of slack so you can hook up the spring and put the belt in the right position on everything else then go back to the deck right hand pulley start putting the belt back on that pulley and when it is to tight to get it all the way on reach under the deck and use the blade as leverage to finish turning the pulley and walk that belt on the rest of the way ,it will not hurt a thing, all you are doing is pulling that 7 inch spring over like it was intended to be, then replace the cover on the deck spindle.

here is a diagram from the internet, hope it helps.

i had a 2148. you remove the mower deck as the first step. feed the belt over the pulley on top the transmission, then put it over the engine pulley. then have someone push the clutch pedal in so the tensioner pulley moves, put the belt in the guide pulley and on the tensioner. release the clutch put the deck back on and you are good to go. notice there are little keepers welded to the frame for the front, engine, pulley and it is easy to mistakenly put the belt over them instead of under them.

a general rule is that a pulley shaped like a Vee takes the V of the belt whilst a pulley which is flat takes the flat back of the belt. if you bear that in mind you will not have a problem putting belts back on. also there is a little decal on top the deck showing how the deck belt and deck drive belt go.

nope..you can put the belt back on while the deck is still attached...good luck

there should be a routing diagram sticker somewhere on the deck. look at the back side of the deck in the middle

I don't have a deck diagram but you should be able to figure it out it you put the back part of the belt (flat) up against the pulleys that are wide and the narrow part (v) into the smaller pulleys. It might take a couple of times but it is not that hard to figure out. Also put the (flat) side of the belt on any tension idlers. Hope this works.

there is a long rod on the left side on the deck. That is like a belt tenioners just move it an you have a lot of free play. Put the belt on pully and replace the rod back in it's spot it takes all the free play out.
