I bought a CK20HST last week and have been putting it through some paces, and so far, it's been great. It will do all that you need to do, mowing 5 acres will be a cinch. I have a loader, backhoe, brush mower,boxblade, and a boompole, and I can get just about anything done. I pulled 3 large (8ft long) pine trunks down to the creekside here a few days ago. I only had to put some cinderblocks into the loader to keep the front down, but it didn't complain at all and pulled them just fine. I don't think you could go wrong with either the CK20 gear or hst model and the pricing is great with 0% interest for 36 months available. I am NOT a dealer, just a user and now, Kioti convert! John
