I can walk faster than my L4701

[MDB72513]

Tractor loses power when driving up slight inclines (think 1 foot drop over 20 in length) in normal operation; simply comes to a stop and engage 4 wheel drive to move. It cannot pull a 5 foot rock rake, let alone a 5 foot mower unless it is in 4 wheel drive. I’ve heard that it may be the clutch, but that answer came with an lack of confidence.
I’ve done the following;
New fuel filter and water separator screen.
Filled/topped off hydrolock fluid.
Any help would be great.
Thanks,

hydrolock? I hope that was a typo - you mean Hydraulic?

And this is a HST model not the synchronized shuttle version?

IF you have HST - you in high range when this happens?

Yes; typo. Was in a rush typing this. Sorry.
No, it’s not an HST.

Does it do this in every gear and range?
Does the engine speed slow down or just tractor movement?

Every gear.
RPM’s are at 1500 - 1900 with no change.
It’s like rolling up a hill to a stop light. Stopping, then letting your foot off the brake and not moving. Just odd

Going off your first post, it will move uphill only in 4wd? But not in 2wd?

 

[PHPaul]

Gear shift trans then? Sounds like clutch issues to me.

 

[BAP]

If it moves in 4wd but not 2wd , sounds like something broke in the rear end. Bad clutch would not pull in 4wd versus 2wd.

 

[old and tired]

Check tire pressure in rear tires. Make sure the wheels are not spinning inside the tire. Mark the tire and rim in the same location (or photo of valve stem location on tire). Long shot, but easy to test.

That is correct.

if this is the rear end, could broken #070 explain it ? never seen 'keys' in a diff,so curious as to why they're there. If it drives fine in 4wd(pull a load) doubt it's the clutch.

 

[North Idaho Wolfman]

There are quite a few parts that will make the rear no have power, could be everything from broken axle up to the coupling to the differential and everything in between!

 

[GreensvilleJay]

That is correct.

so really it's a FWD tractor OR will it 2WD on level ground ?

The keys lock the shafts to the diff housing to keep them from spinning.

Does the tractor pull ok with the front axle engaged?

thank you ! been thinking about it since finding the drawing, just seemed 'odd'.
one mystery solved.....onto the next one !
