OPERATION

OPERATION

The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing conditions, the RX60 mower requires a tractor with at least 35 HP, the RX72 mower requires a tractor with at least 45 HP and the RX84 mower requres a tractor with at least 65 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding 90 HP (Model RX60) and 100 HP (Model RX72 & RX84) may cause mower damage by overpowering the unit in heavy cutting conditions.

3.3 3-Point Hitch

The tractor 3-point hitch must be rated to lift at least 1000 lbs. (Model RX60), 1200 lbs. (Model RX72) and 1500 lbs. (Model RX84). The Model RX84 is designed to be mounted on a tractor with CAT II ir CAT is designed to bIII 3-Point or CAT III Quick Hitch.

Refer to the tractor operator’s manual for the category of the tractor being used. If the hitch does not conform to ASAE dimensions, the mower may not fit or raise properly. Consult an authorized dealer for possible modification procedures to mount non-comforming hitches.

Depending on the hitch category, certain size pins are used to attach the mower to the tractor. CAT I hitches require 7/8” lower and 3/4” upper diameter hitch pins. Quick Hitch requires 1-7/16” diameter lower pin and 1-1/4” diameter upper pin. CAT II hitches requirie 1-1/8” lower pins and 1 inch upper pins. CAT III hitches require 1-7/16” lower pins and 1-1/4” upper pin diameters.

Our 3-Point Quick Hitch is designed to connect to a Quick-Attach coupler making mounting and dismounting your mower easier. The 3-Point Quick Hitch is also designed to connect the mower to a tractor’s 3-point linkage without the use of a Quick- Attach Coupler.

3.4 Front End Weight

A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005
