I believe it should only have 1" of free play. I would tighten up the linkage but you are probably due to haveing a new clutch installed. That is why you don't loan your equipment out. :)
Wherever you place them, make sure they do not stick out into the bucket area and are set back. Personally I would want two near the outside edges and a center hook. I put a center hook on that stuck out past the top bucket lip. Went to unload a large crate (pto generator) and the hook pierced...
Mine had 1" to much free play and would grind. I took the free play out (except 1") and the grinding stopped. Hope yours is as easy to fix as mine was.
No offence but when I am laying down some large change on anything I buy I get educated on it and what it is worth. Buy the time I pull the trigger I know what I paid and if it was a good bargain. I will also walk away if I don't feel it is a good price. I would not rely or trust anybody elses...
I used to move snow for a living when I was in construction. Often times a 16 hour+ event running a loader, road grader, or pickup plow. I still cringe every time it snows and don't believe I will be ever happy to see the white stuff.
A box blade is the easiest to use and one doesn't have to be overly experienced to get good results. A back blade can do a better job at shaping and pulling gravel back from the edges but requires a little more experience to get excellent results. Both work...I prefer a back blade.
It is not Chicago electric but is made in China...along with almost every other generator and thing made. Putting an American label on it doesn't change that fact.
I have a straight tranny so not sure but I have read numerous posts about hydrostatic trannys whining. Most put in a synthetic fluid when performing maintenance to eliminate or reduce the noise. Since yours is new...I would think it has synthetic or partial synthetic already. Skid steers whine...
I would think if it was an injector it would run rough 100% of the time. If it were mine, I would get it to a diesel mechanic ASAP before some major event took place. Hopefully it is nothing major but I wouldn't take any chances.
I bought a 15kw one from Rural King for $1100 that runs off the pto. Harbor Freight sells the same one for around $1500. Rural King stopped selling the 15kw I believe but do have larger pto powered units. Seems to work real well and has excellent ratings on HF.
