Cool thing is you can grab up a tractor and a stable of pushers for cheap.
I know on my RER (SR1433), it tows my fat azz at 285lbs, a towable core aerator, like 6-8 cinder blocks at 37lbs each and my 135lb wife. That should tow a few pushers.
I have two push only Snappers that need a job. So 33" plus an easy 40 more deck inches....... That would be the b_mb seeing a fleet of Snappers cruising my yard.
