My father-in-law has a Hisun 750.  It has started to not change gears while running.  He can turn it off, change gears, then restart and it will change.  I thought it might have something to do with the brake but can’t find any info.  Thanks in advance for any info.

How many rpms? Mine does this when idling is high. When it got warm I had to change the oil for the 5w40 winter to the 15w 40 for the summer.

There is a safety switch (I think) that is supposed to prevent you from shifting gears without having you foot on the brake. That switch is also supposed to prevent you from starting the machine in gear without having you foot on the brake. I'll take a quick look and see if I can locate where it is. I think it is by the brake light switch at the base of the brake pedal. 

Kinda like the switch that kill the engine of a riding mower if you get off the seat with the blades engaged or in gear and fall off.

Well as usual I'm wrong. There is a pin that prevents it going into reverse unless the brake is applied. But didn't see anything about a separate switch on brake pedal for shifting. Could be the brake light switch has multiple purpose.  I'd check it anyway just to make sure. And check the shift linkage. See pics below.

BUCK,

I have an Axis 500. I have no shift issues. Haven't changed anything with brake pedals.

With engine running, I can go 

N to HI or LO with no brake

LO to HI or N with no brake.

LO, HI, or N to R have to have brake.

R to N, HI or LO no brake.

Start in any position with no brake.

Don't shift to any gear rolling.

I'd check the linkage on your father-in-law's machine.

He said he checked the linkage.

Since the linkage seems to be good.

As T Fox asked, what is the RPM when trying to shift into gear while running.

High RPM could be an issue. And at high RPM the clutch would be trying to engage/engaged also. Putting pressure on the shaft attached to the primary sheave. Trying to move the CVT belt. Making the secondary sheave engage. And the secondary sheave is attached to the shaft that turns gears in the transmission.

And the clutch is in an oil bath also.

      Oil change
      By Joe Breaux
      Decided to do an oil change on the Massimo ...drained oil, screen was very clean even tho oil wasn't.  Then went to remove old filter.. holy crap ..I tried every tool I have, could not budge it..Went to store and got one of the end cap type..fit nice and tight, put a 1/2 in drive ratchet on it..nope..not moving.  Put a 18 on breaker bar o. It. The inside of the removal tool broke off!!  Had to weld it back together. Put a pipe on the bar for more leverage.  Finally broke it loose..
      I have never seen a filter in my 55 yrs of working on engines so tight..And i was the one who put it on 2 yrs ago.  JUST HAND TIGHT!

      By BigWave
      I turned off the key and then tried to start it a minute later and it would not start. I changed out the fuel filter and the injector. still nothing. if i have the injector pulled out and close to the hole the injector will spray fuel into the hole and it will run but the minute you put the injector in it will die. any idea's please
