Thanks for the response, StarTech! My mower is an Exmark Quest S series 708 54" deck. Model: #QZS708GEM54200, Serial: #409481792.

I had an issue with the freewheel or "self-push" feature of the mower. The drive wheels remained locked via the two traction drive transmissions when I wanted to roll the mower through the wet yard to reach the car for battery jumping. On my old mower I just had to place the steering handles...

Thanks for the ideas, Star Tech! Those look more substantial than the tool that eXmark offers. Of course, I'm only looking at the owner's parts manual and their sketches are not always to accurate proportions. 2 years ago, I had oil leakage problems at the base of the engine mount, the mower...

OldDuffus, back after a few years to check in on Lawn Mower Forum. I guess "dufuss" should be spelled like that but my double-F rendering reminds me of Winnie the Pooh spelling, reminiscent of easier days. Can anyone provide some advice to safely remove the idler spring tension to...

I had a problem similar to SHB's or Badboy's with the main drive belt to those two hydrostatic gears (drives) coming off of the pulleys. My mower is a Gravely ZT 24 HP 50" deck and Kohler twin-V engine. I'm just happily zooming around the yard mowing and suddenly the power to the wheels just...

Thanks, bertsmobile1. I have fooled myself that way on many occasions, answering posts that are old as the hills or the problem solved or "expired" long before I ever suggested a belated solution. I'm even late in responding to your post. I guess I imagine that those out there who search the...

Welcome aboard, WFM.

Bolts worked loose from the hydrostatic transmission (at least on one side) is what happened to your mower (as it did mine). In short, the bolts worked loose from the hydrostatic transmission on one side (right side in my case) allowing the aluminum body (the whole transmission on one side) to...

I have more than once made a mistake when I put the mower deck blade belt on. My mistake is to forget to check that the belt actually sits in the "v's" of all of the pulleys before I put the pulley covers on. It gripes me that I will then hear a loud noise which I forget means that I messed up...

I don't think so. You should not have to remove the clutch in my opinion, although it makes it easier to get to things, but not critical. Some say to remove the electric clutch, that fat thing "blob" that stops the blades quickly for safety. You should only have to loosen and drop down the...

Terminology: The upper pulley on a Gravely ZT model 915116 is the "hydrostatic transmission belt" or "ground drive" belt. The lower pulley drives the cutting blades and, unfortunately, is the one that both manufacturers and customers call the PTO belt. Some say to remove the electric clutch...

Hi, agp47, I'm glad you got yer mower running due to the advice about junk in the gas. I am working through some issues with my Gravely ZT 50" mower with a Briggs & Stratton 16.5 HP twin-V OHV. Going on 10 years, I can say that it has been mostly trouble-free for that period. Maintenance has...

On July 19, 2017 my Gravely ZT mower blades stopped suddenly and refused to engage. The red knob you pull out to engage blades had no effect. This happened mysteriously when my grandson was mowing and confessed he had hit a big rock. I panicked and ranted awhile but my anger abated after...
