Just a little update on the KX91-3.As of the other day I have the steel tracks installed on the excavator /forums/images/graemlins/grin.gifThe delivery time for the tracks was from the purchase date till the other day /forums/images/graemlins/mad.gif.Now I can say that I have had experience with both types of tracks,even though the rubber was not by choice.My first observation with the rubber was they are very quiet and smooth /forums/images/graemlins/cool.gif.The rest of the story is downhill from there.The tracks have very little traction, pushing power and the long term reliability is suspect[had issues from day one].If I was to purchase another machine I would not buy with rubber tracks and would have the steel in my hand before I left the dealer.Now I believe that my tracks were defective right from day one and maybe even had defects before I took delivery. At the dealer level they couldn't have been better and went far and beyond what they had to do.They called and got delivery dates[which came and went a few times /forums/images/graemlins/mad.gif].They also talked about the problem with the rubber tracks to the powers that be and voiced their opinion.I still am waiting for a answer 2 months gone by.The person who has authority in this issue won't be back until after the new year to this area[he was here a couple weeks ago and didn't have time to see my problem /forums/images/graemlins/mad.gif].I myself have talked to HQ and had a couple of very good conversations with some people of authority.The problem is they haven't dealt with the issues in a timely manner.As I have said the dealer went far and beyond and was dealing with issues out of their control.Dealing with HQ is something that few would have to do,and would think would be a easy endevour.You would think after reading this that I am quite unhappy.The truth is I couldn't be happier with my machine,now that it is equipped with what I needed in the first place.I believe the machine to be second to none in quality, excluding rubber tracks.The dealer couldn't be better in sales and service.The problem is 3.5 months to get tracks in my book unacceptable.You now have to wonder about parts supply?Dealing with issues with HQ has taken way too long and just get the feeling they hope you go away.I am in the process of writing another letter as requested to the powers that be and wait to see the result.I will keep this thread updated with the results good or bad.Now a few of my observations of the machine.The power of the drive motors is quite strong and plenty of power for this size machine.The bucket breakout force is powerful,and the hydraulics are smooth and respond with good feel on the joysticks.The suspension seat is great and should be standard on all machines.The grease fittings are well placed and recessed to prevent breaking for the most part and takes minimal amount of time to grease.A couple of small things that could have been included IMO are a stopper for the window to keep it open and a fan to behind your head to keep the dust and flies out of your face as well as a breeze.
