Hi. Helping out family using the mower deck on our B1750 to mow about 6 acres. Also doing some work removing small rocks from a newly filled area, hand raking and collecting in the bucket to dump on our growing rock pile.

The mower suddenly seems bound up. I had been using it (almost) no problem until after dumping some rocks I could no longer move forward or back without stalling. I'm still getting used to the levers and shifters, but I used the lever to raise the mower deck and everything seemed fine for the moment. Not sure why it was low at that moment. But I was able to run the machine for a few hours and put it away. Yesterday I wanted to mow and I could not because every time I engaged the mower the tractor wanted to stall out. Same situation as before except raising the belly mower didn't fix the problem.

I know I need to inspect the mower unit itself to see if anything is causing it to be bound up. My question that could save me time is this. I don't fully understand all the levers including whether there is a Mid PTO brake. I've been using the parking brake on a slope. Are those connected somehow. I've engaged and disengaged the mid PTO for the mower 4 or 5 times hoping it would start working. I see there is a differential lock lever, a 2wd to 4wd shift lever. Does the mid pto require these other setting be set a certain way? Like only 2WD or only 4WD? Differential lock vs unlocked.

Printing off sheets from the manual and heading over to inspect mower deck as best I can and to check settings on levers.

Thanks for any help or advice.

BTW my B1750 uses a shift lever for forward reverse etc. I saw another owner here with foot pedals for forward and reverse. So different setups for the B1750 I guess.

Mid mount mowers are designed to mow lawns. They are not designed to mow untended areas. What are you mowing?

Apparently, your gear drive B1750 is not a HST. Accordingly, drive is controlled by a foot clutch and gear shift levers, rather than a HST (foot) pedal. The 2/4WD lever and differential lock pedal operate independently of the clutch and gear change controls.

It appears that your MMM deck is prevented from turning. This can be the result of spindle bearing or belt failure, other damage or, more likely, debris of some sort clogging the deck or belt.

Remove the belt covers to inspect the belt and inspect the underside of the deck for debris, something wrapped around one or more blades, or damage.
