Grinding noise in mid gear only- B3200

[WarrenPFJr]

Hi all,
I've been running a B3200 since i bought it new in 2009. It has just under 1,000 hours on it. Recently i get this click, click, click noise when in mid gear. It does not happen in high or low gear, just mid gear, all the time, in both 2 and 4 wheel drive. It still runs in mid gear but it makes that annoying sound. I have been using the machine in high or low only to avoid damaging anything and really miss the mid gear. I have also noticed with the HST when i start to push the pedal i get a slight jump before it starts moving. Are these 2 things related? Any thoughts on what my issue is?

Thank you!

Could be a broken tooth on a gear.

You'll need to take it apart and see what's inside the magical box.

My 3200 has always had a small ‘surge’ when I first ask it to move, just the nature of the hydraulics. It is amplified in high range.
The clicking could be a number of things, putting the rear of the tractor up on stands and turning the rear wheels by hand (engine off of course) with the L-M-H lever in different positions may help you isolate it.

I got the tractor up and spun the wheels by hand. No noise. Only when I start her up and step on the pedal.

Did you just spin one wheel? The other wheel would just spin opposite thru the differential. Have a helper spin the other so that both wheels are spinning the same direction so it turns the driveline.
