This 36" machine is also designed to do 48" bores with a jacking riser raising the centerline while still keeping a low centerline profile. This machine puts out 461,814 Lbs. of thrust and 38,239 Ft-Lbs. of torque making it the most powerful 36" machine on the market.

Our machine uses a John Deere 4 cylinder engine coupled to a 4-speed transmission and the exclusive Michael Byrne Manufacturing planetary gearbox. Our planetary gearbox is specifically designed for boring machines. Handling the severest shock loads, surpassing any of our competitor models. Also included is a thrust package protecting the complete drive train.

The gear pump supplies 32 Gpm to four hydraulic cylinders with a max pressure of 3,000 psi. This pump also supplies the oil for the push block and winch.

The D36-500 has a tripple bladed dirt ejector. It is held in place by four clamping bolts keeping high pressure ensuring the ejector will not spin.

Our tracks are connected together by quick-disconnect track connectors. Michael Byrne design heavy box constructed frames, for severe conditions for keeping proper alignment of drive train.
