I have a 20 hp koler engin in my hustler. I have had the T20 rebuilt and have put a larger cvt with stiff spring on the tranny. But im still having trouble going up steep hills with trax on. Any advice
If you are sure that you have the correct tension on your belt, then some other options would be a smaller sprocket on the transmission shafts. But first try going to a 40 tooth on your axle.
To check tension on your belt you should have 3" total deflection up+down with the pressure of your little finger only.
Tell us all you can about your Hustler, the more we know the better we can help. How many teeth are on your main sprockets? What engine was in your machine before you went to the 20hp and how did it perform? What cvt setup do you have? Also Is the engine you have tuned for the altitude where you ride? Tracks require more power than wheels, have you tried the same hills w/o the tracks?
I counted 40 teeth on the axel sprocket that the chain from the T20 first goes to. the midel axel has 3 sprockets the 2 smaller ones have 27 teeth and the middel has 40. Yes I tried the same hill with out trax and spun tires 22" raw hides. the point is i could not get up it so I waned to with trax. before i did not have the traction make it now i have traction and not enough power.
The new cvt was out of a snowmobile I just had parts and my cvt stock was 2in smaller than the one i put in. I figured the bigger the more torque whitch was true. the stock cvt just spun the belt on a hill with out boging the motor. even with a brand new belt. the new cvt has a adjustible spring
1-4 4 being the stiffest it is set on that. now the belt dose not slip but the motor wants to die. maby i am wanting to do to much but the hill im trying to go up is 35% and I was told these 6wheelers will go up a 45%.thanks for the feed back if you need any mmore info let me know
the motor was stock at 20 hp kolher 4 stroke i had the carb rebuilt and seems to run good
altitude 4000ft grand junction colorado

Reason: merged three consecutive posts
Tracks require considerably more power than tires as you are already aware, judging by your posts. This may require more hp. Just out of curiosity, I have heard of the tracks slipping on the tires, but this usually happens with wet tracks/tires, and as you haven't mentioned it, my guess is that is not the case here. Going to a 42 tooth might work, but if everything is engaging as you've said, more hp may be your best choice.
yes the trax take away alot of hp but i guess I was trying to sub traction for power. I guess I dont know the real capeabilites of a fully functionable ruber tire machine and a tracked one. I have been rebulding this thing for 2 + years. I had 2 hustlers compete with 2 track kits and 1 axel extenion kit. Now I have 1 running machine using the other for parts eventually it will be gutted for parts and turned into a trailer. do you think the 20hp 4 cycle is better it is much newer or the 38hp 2 cycle it was older and not working but i still have it.
also not trying to push selling stuff but i have a factory hustler aluminuim roll bar i would trade for parts for hustler just putting it out there.factory parts are hard to find and i see a lot of hustlers on this site.
Some one might jump on the rollbar, but for safety's sake you may want to put it on your machine if it doesn't already have one, cause it seems that you are in some steep country.
About the old engine, I'm personally not a big fan of two strokes, because I like to putt putt around, but more power is more power however you get it. I'll bet you could swap it for a bigger 4 stroke if it were running. Talk about a screamer 38 hp YIKES! Yeah definitely get it going then decide what to do. On second thought What would you take for it?
