There are just some inherent differences between a wheeled machine and tracks. I have one of each (SV300 wheels and TR340 Track) Both 90 hp similar lift capacity, same OEM, but vastly different characteristics. Like Swanny says not enough info to answer that really. The best thing is to demo the Kubota and see what you think. I like the track machine for pushing material, working in wet ground and so forth, there are some applications where they are just what you need. They simply are more efficient at putting the power to the ground. However there are jobs that are better with wheels than tracks. Your 450 is a fast cycling machine and is quick moving around a job site. The tracked machine will be slower functioning, slower and with more vibration when moving it around. However it will do better pushing through a pile and working in soft ground. You wont have the hydraulic hp that your CASE has, but again depending on application that may not be important. I have run several different 75 hp track machines and came to the conclusion they are not for my operation. Simply not productive enough, they don't have power to multifunction very well. I found for me I needed the high hp track machine even if I have to deal with DEF, your mileage may differ. I liked the no def solution but at the end of the day I still need to get things done in a timely manner.
