Im not sure how far along you are and how comfortable you are with your progress, but that's what financing is for. Your dealer should have some Spring or even off-season deals. Look into buying a used machine, I have a 48" 20hp kubota diesel ghs with 2500hrs for sale in my area for $5500. Also a 31hp 48" ghs with 2400 hours for $3000, it is a lot of hours but I have seen several Walkers with 5-6k hours on them.
There is an Old Blue Chair for each and every one of us, we just have to find it.
