[oneparsec]

Hello everyone: have 40hp Mahindra and the 4wd won't engage when moving lever to 4wd. Any suggestions a to where to start looking. Thanks

Try rock tractor...turning wheels back forth..tractor has front loader down pressure until front wheel off the ground.

Broken roll pin? If lever is moving and not engaging.

Any resistance on the lever? I would start by crawling under the tractor and check the linkages.

No, lever moved but no engagement

I looked under the tractor. Linkage attached. Should i unhook the linkage and try turning the shift manually. With tractor off of course.

If your linkage is moving the shaft like it is designed to, I would next uncover your driveshaft and gearbox output shaft and examine -Some simple testing here will allow you to determine if the issue is in the gearbox vs driveshaft vs front diff/axle

Use the bucket to lift the front end, then see if it engages.

Good idea to take the load off the front end.
