Mahindra 4500 2WD

[DJP]

My Mahindra 4500 has stopped lifting up the bush hog cutter. It takes all my muscle to pull back the level that lifts the bush hog. It worked ok in the past year. I checked the H-fluid behind the seat, it is full up to the stick level. The bush hog lift level appear to be locked down or something. What can I look for to see why my level is not working anymore, or why it is so hard to pull up????

Holy cow. I’ve had this issue with 3 pt on same tractor. Worked fine for years then all of a sudden no. Lever is so stiff I had to hit it with a hammer to move it. Asked around but never got answers. Luckily I haven’t had much need for 3 pt lately. Following this thread.

Linkage needs lubed? If it has draft control the feed back link is out of adjustment? :confused3:

Thanks for the quick reply JABONEE: Can you please tell me where on my Mahindra 4500 is the Linkage that needs to be lubed? And what do I lube it with H-fluid or transmission fluid. How could my Mahindra lose the lube, the bush hag lift handle worked last year?

Linkage on each model can vary. Most are connected directly to the 3pt control valve. There is a pivot shaft that the handle or linkage connects to. That is most often what seizes up and needs lubed. Move the lever and see whats moving. Doust with lube while moving handle. I like PB blaster but what ever penetrating spray lube floats your boat will do. FYI all hyme joints and pivots should be lubed regularly. Some have grease fittings. Most do not.:thumbsup:

I like PB Blaster too. I had sprayed mine with WD-40 but it made no difference. Jabonee, can you take a pic and post it here?

Sorry, meant DJP.

Thanks again JABONEE: I am looking all around my Mahindra 4500 2-WD and do not see the Linkage or Pivot shaft. My bush hog lift control handle are on the right of the driver seat. There are two handle, one with a red knob and the other a black knob. The red knob lift the bush hog which is now hard as **** to move backward or forward. The other handle is the black knob, it appear to be some type of level gage. Both attached to a metal pipe rod coming from under the seat to the left. I do not see any sign or anything that let you oil or lube these two handles. Are you speaking of spraying or oiling the two handles where they joint together. There is a metal knob at the front of lower seat, between your legs. What do this metal knob do? The only option for adding oil to the bush hog lift is the square bolt behind the seat, that you add HI. fluid to.

There has to be a pivot shaft where the handles are attached and pivot on. There should be a friction nut on the end of that shaft that controls how stiff the handles move. Try backing that nut off and hitting it with some lube. The knob between your knees is the rate of drop valve. It can control how fast an implement will drop on your 3pt. Think of it like a faucet valve on your sink. The further open it is the faster the implement drops.

If you are talking about the nut I think you are, I loosened mine to the point it was almost off. Made no difference at all.

follow the shaft to all points and lube it there.. if the lube don't work the issue will be inside the frog
