<font color="blue"> a tc 24 might be ok with the 60" box . I use my old 60" on my old ford 8n.. which was 27 hp back in 1952.. Your tc24 is more hp due to the age of my N.. and is generally a superior machine. </font>
He has a TZ24, not TC24. My TC18 is the same size as a TC24, and I have great difficulty using my 60 inch box blade on it. His subcompact TZ24 will definately not be able to use a box blade that large.
Also, since he has a subcompact, and is looking at a King Kutter, he should take a look at King Kutter's XB line, implements that are exclusively made for subcompact models.
Rather than trade my 60 inch box blade for a smaller model to be able to use it on the TC18, I exclusively use my box blade on the 8N, and it does a great job. I've recently gotten quite good at using it, and not only use it to break up dirt and do grading work, but I also use it to move dirt from one side of the yard to the other, since I lack a front end loader. It's a pretty neat tool for $250, and I recommend a box blade to anyone doing any sort of landscaping work! /forums/images/graemlins/cool.gif
