need help lifting mower

well after sarge gets his new heart i planned on doing a 5" to 6"lift but what i was wonderin is how would i do the rear transaxle lift do i try to have the input shaft extended i was hopping to get a 8" 5/8inch keyed shaft and a 1" long shaft coupler and connect them to gether and install a pillow block on e top of the pully an as close to the base of the shaft collar but i cant find a 5/8inch bore shaft coupler thats 1" long im really stuck here i dont want to weld anything on my transaxle like what should i do im on a super tight budget here sarge has been lift 1 1/2" aleady i just lowered the transaxle mounts and slide the pully up and put a new key in it but i cant move the pully any higher with out it falling off the input shaft btw the pully is a 3" the front is gonna be a 4 1/2 or a 5" please im out of ideas here and sorr if this is the wrong place to post this i thought i should post it hre because it is tansaxle related

Check out fireman's build. He used a coupler for his. You just need to look harder.

Im sure you can just buy 2 of the hubs for those weld-it-yourself pulleys and weld them together to make it longer.

ya i seen his build i didnt know what he used i thought he just used a shaft collar well thanks for the help

Welding 2 of those hubs together with the keyway lined up would work fine. As for a support for the extension, a pillow block will work.

Just copy what fireman did basically.

thats what ima do it will be really easy plus i have lots of time on my hands oh and this was on my mind my great grand father when he was alive i was only 11 but his mower had a gear pattern like this 1_3_ no high and low
2 4 R
but it just came to mind because he was out there one day and he would shift it like a car it was funny i think the top speed was 25mph but 2nd gear was messed up so when he had to shift into 2nd it wold grind but 3rd and 4th worked fine and it made me wonder if there was any transmissons for a mower that shifted like that and looked close to a pearless 700 series

My JD is like that

4-N-3
2-N-1

But with some imagination you can make the gears go how you like them too with a guide plate and a hinge.
