The ck20 is a tremendous tractor and I kind of miss it as well. It was not just the hours comparison that prompted me to make the upgrade/equalgrade. It was nice to drop from 1600 + to zero hours indeed but I move a lot of snow. I wanted the luxury of a cab with heat and a front snow blower as well so the exchange was quite a temptation. I ate enough of that snow while backing and watching backwards from the seat of that 20 with a rear snow blower to jamb pack Times Square twenty years into the future. The Kioti backhoe that came with my CK20 package in 2007 got recycled to the back end of the 2510 and it continues to dig any stump onboard the ck2510 to this day. The only real difference I can see is probably a plastic hood in place of the 20's steel one and maybe 6 quarts of Rotella 15/40 oil over the 3 + for the 20 at oil change time. I'm not aware of any real difference in horse power. The 2510 steering is a little quirky at higher speeds. I have not quite figured that one out just yet. My hand at adjusting the tie rod ends has not been successful. It just that a slight correction seems always overdone when steering down the road at faster speeds
