OutdoorKing Repair Forum Forums Repairs and Maintenance Questions On Ride On Mowers Questions on Greenfield Ride On Mower Frames Greenfield - Transmission Problem

Hi Guys,

I've just discovered this forum and was wondering if anyone can help me with a problem I have with my Greenfield Mower.

I last used the mower about a fortnight ago and backed the tractor into the garage and everything was normal.

I went to use it today and can't stop it going backwards. If I push the pedal forwards that will only hold the tractor stationary and as soon as I release the pedal the mower goes backwards.

I am probably overlooking something really simple but any advice would be greatly appreciated.

Cheers

Hi perch, welcome to Outdoorking.

It sounds as if the reverse clutch is being engaged when the pedal is not being pressed. That might mean something wrong with the linkage between the pedal and the clutch thrust bearing between the two large clutches under the seat. Depending what model your Greenfield is, there might be an adjustable pull-rod there, or a supposedly-fixed linkage.

Please post some pictures of the clutches under the seat, showing us some detail of the thrust bearing in the center, so we can see if it is being pushed toward the reverse clutch.

Here are some photos. Hopefully they show what you want.

You can see that the thrust bearing is positioned closer to the right-side clutch (the forward clutch IIRC, but Gadge will sort me out if necessary). For this to happen in the rest position of the pedal seems to suggest that the clutch spring for the forward clutch may have broken, preventing pressure from being applied to the forward clutch. The spring for the reverse clutch would still be functioning if that is correct.

If I am right you are going to have to remove the clutch shaft, complete with clutches, and dismantle it on the bench. You will immediately see whether there is a broken or missing component on one side of the thrust bearing. There are several threads available here at Outdoorking that will explain in detail how to do this job. However before we get too attached to this diagnosis, let's see what Gadge says - he has plentiful experience servicing these machines professionally.

Yep, that's the forward clutch right enough. As grumpy says, the problem is in the centre of the clutch assembly, and it is going to have to come out, to see what's happened; that spring is indeed the most likely culprit.

It's actually many years since I worked on Greenfields; but they have changed so little in their essentials, that the old knowledge still applies. The benefits of having a sound design, and sticking with it!

Great. Thanks for the advice I'll see how I go.

there should be 2 metal spring clamps inside the clutch housing, these keep the 2 clutch pieces together, and moving as one complete piece, you will need to completly remove it, and make sure these spring clamp thingies are connected correctly
