I have been lurking here for a few weeks and absorbing what I can. I currently own a 2001 Kubota l4310 HST that has served me well. I was looking to add quick tach, turfs, third function and draft control. These additions were going to cost 4k to add to my current machine. I recently can across a 2003 DK45 that is a near carbon copy of my 4310. The Kioti was equipped with all of these features. I was a little hesitant about the shuttle shift vs the HST but after operating the shuttle shift, I think it is going to work out just fine. The DK45 seems to be a great machine with around 600 hours. I have a few questions that concern me with the new machine:
It has foam filled turf tires. I really like the idea of this but the front tires are going to need replacing in the near future. How bad is it to change out foam filled tires?
While inspecting the tractor, I pulled the dipstick on the rear housing of the transmission and noticed that there was a bit of pressure release when the dipstick was removed. Is this normal?
I had read of a few having issues with the front engine seal going bad. Is this a common issue? I inspected the area behind the front pulley and it showed no signs of leaking
Here are some pictures of the new rig.
