To lift, or not to lift...

I have a sears compact 8 with a flat bar axle up front, and im curious if anyone has lifted something similar. Im going to put 15x6-6 tractor treads on the front, so idk maybe it doesn't need a lift. Am I barkin up the wrong tree trying to lift this?

If you want to offroad it you want to go even bigger, 15" tires aren't going to roll over objects very well trust me. It has 8" front wheels doesn't it? Lots of 18 and 19" tire options of the ATV variety that should fit, out back you can squeeze 25 tires under the fenders.

Here's a pic of my friends Suburban 12 with 25 or 26" out back and 20" up front, his tractor is so capable it's actually a little ridiculous BUT because of the height and thin wheel track it can be tippy at times,  it's not a light tractor either!  

The front tires on my simplicity are 18", they aren't too bad but bigger fronts are always better for obstacles if you can fit them. Unless you're on relatively flat ground all the time. In that case it wouldn't matter that much. 15" is probably better than stock tires i'm sure.

@Brianator After researching your suggestion about bigger tires (and yes, they are 8 inch wheels), I noticed most of the 18-19's were 7 inches at the skinniest. I have a set of 20x8-8 turf savers that I thought were too wide for the wheels, but I went for it and mounted them on the rims. The skinnier rim definitely makes them taller. The 15's are on their way back to the dealer. Thanks for the suggestion!

Do you think I could cut out and slot the frame to give the flat bar axle more travel?

Probably, but be careful the axle or tire doesn't bust your grill.
