a carriage assembly slidably mounted on the track assembly, wherein the carriage assembly is configured to move the drill pipe along the track assembly;

a gearbox assembly coupled to the carriage assembly, wherein the gearbox assembly is configured to rotate the drill pipe;

a pair of spring slide assemblies configured to couple the carriage assembly and the gearbox assembly; and

a hydraulic jack assembly coupled to a first end of the body, wherein the hydraulic jack assembly is configured to adjust a height and an angle of the drill.

2 . The drill of claim 1 , wherein the body comprises:

a frame; and

an attachment bracket coupled to the frame, wherein the attachment bracket is configured to attach the drill to an external hydraulic device.

3 . The drill of claim 2 , wherein the external hydraulic device is a backhoe bucket hydraulic cylinder.

4 . The drill of claim 1 , wherein the track assembly comprises:

a guide rail; and

a track plate.

5 . The drill of claim 1 , wherein the carriage assembly comprises:

a thrust drive gear;

a hydraulic thrust motor coupled to the thrust drive gear; and

a track roller.

6 . The drill of claim 5 , wherein the thrust drive gear engages the track assembly.

7 . The drill of claim 5 , wherein the track roller engages the track assembly.

8 . The drill of claim 1 , wherein the gearbox assembly comprises:

a spindle configured to rotate the drill pipe;

a drive gear coupled to the spindle, wherein the drive gear is configured to rotate the spindle; and

a hydraulic drive motor coupled to the drive gear, wherein the hydraulic drive motor is configured to actuate the drive gear.

9 . The drill of claim 1 , wherein each of the pair of spring slide assemblies comprises:

a carriage mount coupled to the carriage assembly;

a gearbox mount coupled to the gearbox assembly; and

a shaft passing through the carriage mount and gearbox mount, wherein the shaft comprises a spring mechanism at each end of the shaft, and wherein the gearbox mount is configured to slide along the shaft with respect to the carriage mount.

10 . A drill for drilling a drill pipe into a surface, comprising:

a body;

a hydraulic jack assembly coupled to a first end of the body, wherein the hydraulic jack assembly is configured to adjust a height and an angle of the drill;

a track assembly mounted on top of the body, wherein the track assembly comprises;

a guide rail; and

a track plate;

a carriage assembly slidably mounted on the track assembly, wherein the carriage assembly is configured to move the drill pipe along the track assembly; and

a gearbox assembly coupled to the carriage assembly by a pair of spring slide assemblies, wherein the gearbox assembly is configured to rotate the drill pipe.

11 . The drill of claim 10 , wherein the hydraulic jack assembly comprises:

a telescopic leg configured to adjust a height of the drill;

a hydraulic arm configured to actuate the telescopic leg; and

a support foot, wherein the telescopic leg is hingeably coupled to the support foot.

12 . The drill of claim 10 , wherein the carriage assembly comprises:

a thrust drive gear to engage the track plate;

a hydraulic thrust motor coupled to the thrust drive gear;

a track roller to engage with the track plate; and

a first edge track roller and a second edge track roller, wherein the first track roller is configured to capture a top surface of the guide rail, and the second edge track roller is configured to capture a bottom surface of the guide rail.

13 . The drill of claim 10 , further comprising:

a spring slide assembly comprising:

a carriage mount coupled to the carriage assembly;

a gearbox mount coupled to the gearbox assembly; and

a shaft passing through the carriage mount and gearbox mount, wherein the shaft comprises a spring mechanism at each end of the shaft, and wherein the gearbox mount is configured to slide along the shaft with respect to the carriage mount.

14 . The drill of claim 10 , wherein the body comprises:

a hydraulic wrench assembly coupled to an end of the body opposite the hydraulic jack assembly:
