I will start by telling of my first tractor a Ford 3600, about the same horse power. My 3600 did the job and it might be around long after my Kioti bits the dust. But it was at the time in its life that it was costing me about 500 dollars a year in repairs, mainly from age, and I just wanted newer and less maintenance.
I only have 10 acres and to most my DK40se may seem over kill. I mow all 10 acres half rotary cutter and the rest finish mower both 6feet, and I do it quick and efficient. I keep the FEL off most of the time, just makes it easier to mow.
Other uses include snow removal, post holes, FEL work, grading and heavy lifting. The pallet forks are one of the best acc. I bought for this tractor. It does not take much of a incline to get a 2 wheel drive tractor stuck with hard frozen ground, with that little thaw on top (like snot), so that 4wd sure comes in handy.
The only problem has been that about one in thirty starts the stop solenoid does not release and does not start, one key turn to off and back has always fired right up. And always just the one cycle of the glow plugs has been enough for start, even down to 10 degrees.
So far its been a great tractor and I love to get on it when ever I can, but I think the barn cat gets more seat time than me (wished I could have afforded the cab).
