I found a parts diagram and Justman777 is probably correct. The metallic stop sound is the crank arm connecting rod hitting the top of the lift piston. For whatever reason the piston is not retracting fully and the crank 'floats' when the lowering angle is set. Most likely MSL valve.
Threepoint, $150-/hr x 3+ hour round trip x 2. This tractor should not have been delivered in this condition as the 3 point never worked. I have 35 hours on the tractor. Numerous failures, loose bolts, and leaks because of the assembly/set up by the shop I purchased from. I'm tired of fixing their problems and I thought my salesman was going to help me out with some of the cost to transport.
Great tractor otherwise.
I had numerous issues on both my Dkse tractors upon delivery as well. Most all problems were dealer assembly issues.
Between the two tractors,
*Crushed hyd steering hoses when loader was installed
*Steering knuckle bolts were loose
*loose loader bolts
*lockwashers on wrong end of fastener
All stateside assembly stuff. This dealer eventually went out of business and a new one opened a year later, 5 miles down the road from the first. They are MUCH better in regards to assembly.
The only issues I had, that was not dealer related, was the MLS valve on one unit. 3 pt bounced like crazy when trying to raise. I removed the MLS valve myself, and through the side of the assembly I could visibly see a check valve needle that was seated sideways in its slot. I popped it and the spring out, seated them properly, though the spring was a little wonky, and all was fine. 3pt worked as advertised. I mentioned this to the dealer, with photos, to see if I could just get a new spring in case the current one failed, and they exchanged the "fixed by me" MLS valve for a whole new one, no more questions asked. ($900 part)
This all happened within the first 5 hours of each tractor. I was far from impressed out the gate. Now, a total of around 1000hrs later, not a single issue, aside from an $8 start relay. All oil samples have come back in excellent condition, both ALWAYS start on the first try, no matter how cold it gets up here in Maine. I'm a big maintenance/tech guy, and like having ALL info I can gather about my equipment, and the more I dug, the more I like the tractor. Very little proprietary crap, Bobcat, McCormick, and Cub Cadet all use similar or same parts, depending on model, so parts are everywhere. PDF Workshop manual is one of the best I have ever seen, and I've read my fair share of equipment manuals.
In my opinion, If Daedong would support their US division better, they would really take a good chunk of the market, and climb up to the likes of Kubota. And as these Kioti tractors age, it will become more and more apparent. But the support needs to be there, and that's where Kubota has it right.
