I have a 2001 Gradall 534c6 telehandler with a pile of hours but does the job around the farm so really not interested in upgrading for 15hrs of use each season. I have a couple problems currently. 1st problem is the speed which is about 3 mph tops going forward, reverse just a bit better but not much. Yes, I have the left side inching peddle all the way back. I have the traction control peddle back also. 4x4 switch is also off on dash. Hydraulic fluid is 2/3 up on site glass so is fine. My mechanic that has been trying to troubleshoot it says it could be a micro safety switch somewhere near the back of the boom on the frame but all I can see it the back up alarm. He said this micro switch may be bad and he is thinking that the machine thinks the boom is extended thus keeping the machine in safety slow mode. My 2nd problem is when I use the blinker shift lever to the left of steering wheel to go to reverse to forward or forward to reverse, the delay is quite long as you could have a cup of coffee before it reacts to either forward or back--it does eventually go but foot accelotator pedal has to be to the max to get it moving to it's 3mph! Any suggestions or past experience or know how to figure it out would be greatly appreciated. I guess I am just waiting to hear from that old gradall mechanic that knows exactly what I am talking about and to point me in the right direction---in which I would like to get there going 10 to 15 mph! It is a fully hydrostatic machine but in 2wd it should be able to obtain this speed is what I have been hearing.. Thanks, AlleyCat
