I have been using a X300 for 11 years now and has served me mostly well. I use it in winter for snow with a blower and that is my main issue. The tractor can get stuck on flat ground if slippery at all. Chains and weights are no help and i myself an 220lbs. Have been looking at Posi drive units in the 500 series 570 is nice but once you are up to the 590 the price gets a bit staggering.(i can only fit 48 inch deck in shed) We are talking small car prices. I have put new trans in x300 last year. Should i just add more weights or take the plunge and at least step up to the 570 so i can get the Locking diff option.
Any constructive input would be appreciated.
