Speed Blade Shaft | Multiquip SP-6457 TD guide

4-Speed Blade Shaft

The exclusive 4-speed Blade Shaft allows optimum performance with a variety of different blade sizes under a wide range of conditions.

Fig. 20 — The 4-Speed Blade Shaft

The 4-speed design fully encloses the transmission, bearings and Blade Shaft, and features an oil bath lubrication (no grease fittings). Oil is cooled, filtered and circulated, and the assembly utilizes a remote, protected fill and vent. Gear changes are made with rack & pinion shifting. Positive shift lock prevents the multi-speed Blade Shaft from jumping out of gear. A Blade Shaft tachometer assists in gear selection.

The 4 gear ratios are:

1st Gear	1.00	: 1
2nd Gear	1.34	: 1
3rd Gear	1.70	:	1
4th Gear	2.02	:	1

The 1: 1 ratio is for the smallest diameter blade. The middle two ratios are for

intermediate sized blades and the 2.02 : 1 ratio is for the largest blade. Blade range is from 16” to 48”.

See page 21 or visit our web site: www.multiquip.com for additional discussion of the 4-speed Blade Shaft, gears, and sheave ratios.

To calculate Blade Shaft speed, assuming a 1:1 ratio between engine and blade shaft input, divide engine speed by the selected ratio. For example, for the 3rd

gear Blade Shaft RPM: 2500 Engine RPM ÷ 1.7 = 1470 Blade Shaft RPM in 3rd gear.

The gear pattern is marked on the casting around the shift lever.
