It has a 7sp with a hi/lo range, from what ive read this is called "varidrive" and uses a spring loaded pulley....is this correct?
Ive also read its garbage...so im trying to find out what issues to look for as well as resoulutions. I never even heard of varidrive till i got this thing.

They are really a pretty good drive system, older JD 1XX and 2XX used a "Variator" same as the Massey Variable Drive. The big difference is the Peerless 4 speed transmissions the variable drives connected to compared to the forward-reverse only on the MTD. My old MF-10 has a ton of hours on it and the variable drive has never been an issue.

The biggest problem with those it when they have been setting for a long time the variable pulley gets rusty and wont move, the needle bearings crust up and wont turn and rust on the pulley where the belt rubs will chew up the belts. Replacement parts prices have a big range. from $40 to $140 depending on part number. When they work they work good, when they dont , they are a pain in the a$$.
I had one on a hot rod drag mower. You could pull up next to a guy that had a mild pulley swap and mash it and pull the front wheels as you pass him

What about the belts? I read they use a special kind of belt?

Standard size belts, but they can be a pain in the a$$ to change. the fender pan may need to be removed if the battery is not under the seat. If the battery is under the seat and it has the pull out battery holder, you can get an arm down the hole to work on the belts

MTD's garden tractors got the benefit of a low range while their lawn tractors only had a single speed transaxle. I like the vari drive, it's my favorite set up for mowing. Smooth, simple, and tough enough to outlast most of the hydros. I think a lot of people love to hate it because they probably had one and put cheap v belts on it. MTD drive belts are a different shape than normal v belts and they are reinforced with kevlar. Even more expensive belts aren't any better. A few years ago I bought a different brand that was supposed to be better. Well, they were reinforcement with polyester instead of kevlar. Polyester shrinks when it gets hot. These belts would shrink so much the clutch/brake could no longer disengage the drive belt. I had to set the belt tension so loose the tractor would hardly move when I started it. Then by the time I got done mowing my lawn the tractor would be creeping through the clutch/brake.
