Can I Soup Up My Mower???

    So I'm having this crazy idea. I want to go faster than my officially sanctioned 6.2mph on my 36" Toro T-Bar. I am thinking of buying a slightly smaller pulley for under the tranny. That way I get a better top speed, but can run in 3rd or 4th if it proves to be too zippy.

    Any thoughts? Any ideas where I could find random pulleys?


    (And, yes, I'm considering a deterioration of my quality of cut by doing this, I know, I know...)

    Ha. I just want more efficiency without having to buy another mower. Is that too much to ask? Scags do 7.4mph. Gravely's do 8.5mph... All have the same max blade speeds thanks to OSHA. So I want to get a little more from mine.

    Depends - without detail I have learned that you can up- engine speed along with blade tip speed and increase your travel time. I know - I can here ya coming about safety, employee's etc but I won't be outcut, outrun, or out done! With all my issues this summer with my Toro's - I need an advantage somewhere!

    Scag WB only go 6.2 as well. But I see your point on gearing your mower faster for efficiency. I would check your local hardware store or have a local machinist make you one. I wouldn't gear it up too much though...Just my .02 cents. Let us know if you decide to go with it and how it goes! Good luck!

    Check this link to verify Scag's speed. Middle of the page.


    I really want to do this. I can always return to the OEM pulley if it doesn't work... but I don't understand why it wouldn't.

    Walkers have a pulley made by Walker to do this same thing.

    The way I see it, is that the peerless tranny is plenty tough (and cheap in case I push it too hard) and other than that it's just a belt-wear issue.

    Exactly. Why do you want to go that fast on a 36" anyway? Are you using it for wide open fields or something.

    Our local bearing house also happens to be a Stens dealer. I would look around for a bearing supplier. They typically carry Browning or Murrey pulleys (also called sheaves). They may also carry different sizes of belts.

    Not to be patronizing, but isn't that a dumb question? The faster I move the faster the work gets done and/or the more work I can handle.

    I do 65% residential (5-10K) and 35% commercial (1/2 - 2 acres). I can't justify a bigger mower because I have too many narrow gates and I live in the Rockies. Out here the wealthy live up on the benches of the mtns which equates to crazy hills and landscaping... No place for a Z mower. Crap, even a 36" scalps a lot of turf here...
