First let me say that you guys rock. Best machines, best dealers, best at responding to problems on forum. I have a eXmark 48" belt drive w/14 Kaw about 10 years old. It is a mean machine to say the least. The problem is....when I got it used, 1&2 gears weren't worth a flip. I had to push it up the slightest incline and I could stand still and easily hold the mower in place while it was supposed to be moving. I couldnt' have this because it wouldn't load on to the trailer. I took it to a back woods repair shop ( my neighbor ) who informed me that the transmission was fine, but the pully needed adjustment and someone welded it in place. He put on a larger pully. The end result was that 2nd gear worked awesome, but now 3rd was slower and 4 was absolutely nothing. Not too big of a deal cause 3rd was pretty fast even though it was slower than before. Fast foreward to today. I now have 2 wheel sulky and I know this machine will cut faster if I could only MOVE faster but I got no 4 and a slow 3. Get me? It's a big deal now cause I can really increase my production! On top of it all, now 1st and 2nd are starting to suck again! 1. How come I have to choose between low gears working or high gears working? 2. The the main pully coming from underneath the motor opens and closes like a sandwich type thing. I assume that this is the design but want to double check with you because if it's not, I have a pully that is broken in the place where the cream filling would be in an Oreo. 3. I don't want to take it to the dealer cause I feel like I'm missing something small. Some general concept like the pully size screwing it up or the wrong belt( by the way belt is 4030 18 df on a model 48-14K ). Help me PLEEEEAAASSSSEEE. BTW- the gears suck even when I'm not using the sulky. And if this post is not long enough, just let me know and I'll stretch it out some more for ya. Thank you, Landscraper.
