2015 USLMRA Rule Book Update from National Tech. Director
« on: May 06, 2015, 11:33:21 am »
6 May 2015
          Subject: Amendment/Change to the 2015 Rule Book

1.   After ongoing discussion with the National Chief Steward Rich Webb and having spoken to several Drivers last season and at Avon Park, Charlottes Motor Speedway and Atlanta race this year it has been agreed upon to make the following changes to the 2015 Rule Book effective on this date 5 May 2015.

2.    Due the increased speeds that today's race mowers are achieving it has been decided to change the 2015 rule book to allow all “Prepared Class Mowers and  the FX Class” to have Side Bars commonly known as Nerf Bars mounted on the running boards as long as they meet the set dimensions noted below. Note that sheet metal/aluminum will be used to cover the side for added protection if they are used on these mowers.

3.   Additionally “Prepared Class” Mowers with Horizontal Engines that were factory built with such will be permitted to have driveshaft’s as long as the Mower has an operational Clutch, however the drive shaft will go to a shift able transmission and the transmission will connect to the rear axle by either Chain or belt.

4.   In the FXT Class Driveshaft’s will be permitted as long as the driveshaft connects to a gear box. At no time will the driveshaft be connected directly to the rear axle.

5.   As stated previously these changes take effect immediately and will be included in to the 2016 rule book

6.   Questions can be directed to Manny Torres @ csm.torres@netzero.com or the National Chief Steward Rich Webb.

Not to cause a ruckus, but in drag racing we were required to have a "hoop" around the driveshaft just before the rearmost joint to protect the driver and track crew in case of joint breakage. It contains the shaft in case of a joint explosion. Might not be a bad idea to incorporate this in the rule book too.

I'd like to see "hoops" at the front and rear of the shaft.  Rear to keep shaft contained from hitting driver and front to keep it from becoming a catapult.

They also need to have a good shield.  Mainly so clothing and limbs can't become tangled. 

I'm acutally planning on building a new mower next winter using a driveshaft.

Is a deck still required or can foot board's be fabricated ?  As so that you can't get a foot tangled in them.

I'd assume on prepared chassis you still have to run decks. 

But they have been chopped so small it don't really matter anymore. 

I hope they stay in the prepared classes.   Those are suppose to look like mowers.

No but you are allowed.

No pics. But drive shaft to a gear box.  Chain drive an axle.  Put a clutch in there somewhere.
