No is my vote. I am always very nervous when some one says it just needs this or that. If the belt came off the last time he mowed, why didn't he put it back on? Could it be that something is making the belt jump off and that is why he wants to get rid of it?
I paid $300.00 last year for a 1420 Hydro, which is basically the same tractor with a 14hp motor instead of the 12.5hp. Afterwards I felt like I paid a little too much. It's still running, but I only use it for mowing and pulling a cart. I use the JD X500 for heavier duty tasks. I've got to change the hydro fluid and filter soon. The last time I ran it it was starting to make a whining sound.
