In this аppeal, plaintiff Smith Machinery Corporation (Smith) argues that the district court improperly granted summary judgment against it on claims that Hesston Corporation violated section 1 of the Sherman Act, 15 U.S.C. § 1, and its New Mexico antitrust law counterpart by tying sales of Hesston tractors to sales of other Hes-ston farm machinery, and improperly dismissed its similar claim under section 3 of the Clayton Act, 15 U.S.C. § 14. Smith also contends that a related New Mexico state court decision precluded the federal district court’s grant of summary judgment on the state claim.
Smith is a Roswell, New Mexico, dealer оf irrigation equipment and farm machinery serving the Pecos Valley area. In 1950, Smith began carrying a line of Hes-ston farm machinery, consisting primarily of hay and forage equipment. Among the most popular Hesston products were the windrowers and the big baler. Smith also has carried a variety of other agricultural equipment lines, including a full line of John Deere products, which has been Smith’s principal line of farm equipment since 1962.
In 1977 Fiat Trattori S.p.A. of Italy acquired a controlling interest in Hesston. Subsequently, Fiat sought to market its tractor in the United States as part of the Hesston product line. In 1981 Hеsston approached Smith about carrying the new Hesston tractors. At the time, Hesston and Smith were parties to a distributorship contract requiring Smith to “order, keep on hand and display a representative sample of each type of Hesston products [sic] applicable to [Smith’s] trade area.” I R. doc. 93 exh. A at 1. Smith declined to carry the tractors. According to its president, Smith refused the tractors because it already had successfully marketed John Deere tractors, the tractor market in the Pecos Valley was so saturated that any sales would be mere replacements, any sales of Hesston tractors would cut into John Deere sales and would not increase Smith’s profits, and Smith’s marketing efforts with regard to the John Deere tractors would be diminished. At no time did Hesston tell Smith it could not continue to carry competing lines of products.
After Smith refused the new tractors, Hesston terminated the dealership and entered into an agreement with the local International Harvester dealer to carry the Hesston line, including its tractors. Smith asserts that had it accepted the tractors, it would have incurred approximately $13,000 in cоsts the first year for new parts, training, and other miscellaneous expenses asso- *1292 dated with the tractors, and would have had to expand its showroom to create sufficient display space. 1
After termination of its dealership, Smith filed suit in a New Mexico state district court, alleging, inter alia, violations of the New Mexico Antitrust Act. At the close of Smith’s case-in-chief, the trial judge dismissed the state antitrust claim on the ground that representative line requirements are excepted from the general proscription of tying arrangements. While Smith appealed the decision to the New Mеxico Supreme Court, it filed the instant action in federal court, alleging violations of section 1 of the Sherman Act and section 3 of the Clayton Act, seeking treble damages. Specifically, Smith claimed that Hes-ston illegally tied the sale of its big baler, windrowers, and parts to purchases of the new tractors.
The federal district court held that the state court dismissal of the New Mexico antitrust claim operated to bar the federal claims on the grounds of res judicata. Subsequently, the New Mexico Supreme Court reversed the dismissal of the state claim, holding that Smith’s proof оf Hesston’s tying arrangement established a prima fa-cie case of a per se antitrust violation.
Smith Machinery Corp. v. Hesston, Inc.,
On remand the federal district court, in a thorough memorandum opinion, granted Hesston's motion for summary judgment on all claims. On the Sherman Act claim, the court reasoned as follows: Hesston’s distribution practices did not constitute a per se violation because Hesstоn did not prohibit Smith from handling competitors’ products and thus there was not a significant foreclosure of commerce or competition; even if Smith’s limited resources effectively precluded it from handling John Deere tractors the amount of commerce thereby foreclosed was not substantial; and, there was no significant danger that Hesston could obtain market power in the tied product market. The court also held that the rule of reason was not violated since Hesston’s tying arrangement actually enhanced competition in the consumer market and, аgain, there was no danger of Hesston acquiring market power in the tied product market. Because the New Mexico Antitrust Act states that it is to be construed in harmony with federal antitrust laws, the court also granted summary judgment on the state claim in favor of Hes-ston. The district court dismissed the Clayton Act claim, concluding that absent any actual sale or contract for sale of the tied item, relief would not lie under the statute.

Smith first contends that the New Mexico Supreme Court’s ruling that Smith had presented a prima facie case of a state antitrust violation precluded the fedеral district court from granting Hesston summary judgment on the state claim. It urges that the doctrines of collateral estoppel, law of the case, and stare decisis bar summary judgment for Hesston. The district court held that preclusion doctrines are inapplicable in cases in which there has not been a final judgment. It also held that the law of the case doctrine does not prevent the correction of a prior erroneous ruling or apply in cases in which new evidence is presented to a court.
Preliminarily, we observe that any preclusion arguments made with regard to the state antitrust claim logically would apply to the Sherman Act claim as well. The relevant state law

is patterned after sec
*1293
tion 1 of the Sherman Act, and mandates a construction “in harmony with judicial interpretations of the federal antitrust laws.” N.M.Stat.Ann. § 57-1-15;
see also Allen v. McCurry,
We think that neither collateral estoppel nor law of the case prevented the federal district court from entering summary judgment for Hesston on the state and federal antitrust claims.

This court and others have conditioned the invocation against a party of collateral estoppel and law of the case on that party’s prior opportunity to have fully and fairly presented and argued its claims.
See, e.g., Kremer v. Chemical Const. Corp.,
The New Mexico state district court had dismissed Smith’s action after Smith had presented its case and before Hesston put on any evidence. The state supreme court reversed, holding that Smith had made out a prima facie case. In holding that Smith had presented a prima facie case of a per se antitrust violation, the New Mexico Supreme Court stressed that its “review of the relevant evidence [was] directed solely at the narrow issue presented and [was] not to be construed as a commentary on the ultimate merits of the antitrust claim,”
Smith,
All the New Mexico Supreme Court decided was that Smith had made out a prima facie case for a state antitrust violation. Arguably by dismissing its case after the Supreme Court ruling and before further proceedings the situation in federal court should be as if the state suit never had been filed. In any event, when the federal court in the instant action considered Hes-ston’s motion for summary judgment, it had before it depositions and аffidavits presented by both parties, as well as trial *1294 testimony from the state proceeding. The court apparently believed that even if Smith had proved a prima facie violation in the state action, such proof had been rebutted upon the consideration of a complete record. We see no compelling reasons for forbidding the district court’s exercise of its summary powers merely because a different court, finding itself in a wholly different procedural posture, thought the plaintiffs case strong enough to withstand dismissal before rebuttal evidence was produced. Thus, the district court properly entertained Hesston’s motion for summary judgment.

We next consider the district court’s grant of summary judgment in favor of Hesston on the Sherman Act claim. Smith argues that the district court, by comparing Smith’s case to Hesston’s rebuttal evidence, impermissibly weighed competing evidence at the summary judgment stage. But as the Supreme Court recently has made clear, there is a crucial difference between weighing evidence, which a trial judge may not do when ruling on a motion for summary judgment, and determining whether there exists a genuine issue for trial. In
Anderson v. Liberty Lobby, Inc.,
Smith’s primary contention is that there was sufficient evidence of an illegal tying arrangement to create an issue for trial. A tying arrangement has been defined as “an agreement by a party to sell one product but only on the condition that the buyer also purchases a different (or tied) product.”
Northern Pac. Ry. Co. v. United States,
As a preliminary matter, we note that to establish a violation of section 1 of the Sherman Act, the complaining party must prove an agreement or concerted activity between separate, parties to restrain trade —that is, a “contract, combination or conspiracy.”

Line forcing, be it full or representative, is a vertical nonpriсe restraint — an agreement between entities at different levels of distribution that does not purport to affect prices charged for the goods.

Taking
Sharp
as our guide, and viewing the conduct before us as a vertical nonprice restraint, Hesston’s line requirement is not a per se violation of the Sherman Act. Smith has not shown that such an arrangement almost always tends to restrict competition and reduce output.

Smith argues, however, that due to its limited financial resources the line requirement would have restricted competition because every forced purchase of a Hesston tractor it made effectively would have foreclosed the purchase of a John Deere tractor. Even if this assertion were true, the argument is misplaced. The primary objective of the Sherman Act is to benefit consumers by promoting efficient and beneficial competition.
See NCAA,
According to uncontradicted statistics in Hesston’s brief, in 1982 John Deere sold approximately thirty percent of all farm machinery in North America. Deere’s share of the North American tractor market was estimated to be twenty-seven percent in 1980 and thirty percent in 1985. If Deere became displeased with the number of its tractors being sold by Smith because Smith also sold Hesston tractors, it had the market power and resources to distribute its products through a different outlet — ei *1297 ther through another local dealer or by vertically integrating itself. Or, as actuаlly happened here, Smith could choose to continue selling only Deere tractors and assume the risk that Hesston would take its product line to a dealer willing to carry and sell its entire line. This is precisely the type of competitive behavior the Sherman Act was designed to encourage. In fact, forcing Hesston to forego established distribution channels to introduce a new product likely would have an anticompetitive effect.
It is clear in this case that the line forcing imposed by Hesston was being used as a tool to compete, and not to restrain сompetition. Had Hesston not been trying to add a new product to its line with an existing distributor, but rather had come to Smith initially with its full complement of products including its tractor, it freely could have gone elsewhere on Smith’s refusal to sell the whole line. Similarly, in the existing situation, we see no compelling reasons to “restrict the autonomy of independent businessmen” when it fosters competitive practices,
Westman,
The district court and both parties focused primarily on the application of Jefferson Parish to the facts of this case, no doubt because Sharp had not been decided at the time of the district court’s decision. The opinion in Sharp did not mention Jefferson Parish, although we believe the analysis in Sharp requires a holding that line forcing is a vertical nonprice restraint that is not illegаl per se.
In our view, there are compelling reasons for making a distinction between line forcing, normally viewed as a method of competing, and traditional tying practices viewed as serving “hardly any purpose beyond the suppression of competition.”
Standard Oil Co. v. United States,
Having said this, we believe that even if the Court were to subject manufacturer linе requirements to the traditional tying analysis set forth in
Jefferson Parish,
Hes-ston’s arrangement still would pass per se scrutiny. In
Jefferson Parish,
the Court held that to find a per se violation, a court first must determine that a substantial amount of commerce is foreclosed under the challenged arrangement, and then that it is likely the seller is forcing the tied product onto the buyer in an anticompeti-tive manner.
C
As stated by the Supreme Court, “the inquiry mandated by the Rule of Reason is whether the challenged agreement is one that promotes competition or one that suppresses competition.”
National Soc’y of Prof'l Eng’rs v. United States,
We have no trouble concluding that Smith failed to make a sufficient showing in this case. The only evidence of “anti-competitive” effect Smith offers, as discussed above, is disputed affidavit statements by one of its officers that each purchase of a Hesston tractor would preclude the purсhase of a John Deere tractor. Yet, as long as Hesston’s arrangement does not preclude John Deere from taking its tractors to market, either through Smith or through another distributor, competition has not been impaired; to the contrary, it has been enhanced. The fact that Smith made a conscious decision to risk the loss of the entire Hesston line by refusing the tractors, rather than give up some sales of John Deere tractors, indicates that Deere would have had no trouble finding a satisfactory outlet for its products. Based on the allegations and evidence before the district court, a reasonable jury could not have found for Smith on its Sherman Act claim and the corresponding state claim. Thus, we hold that the district court properly granted Hesston’s motion for summary judgment.
Ill
Smith also contends that the district court erroneously dismissed its claim that Hesston’s line requirement violated section 3 of the Clayton Act, 15 U.S.C. § 14. Section 3 provides in pertinent part that “[i]t shall be unlawful for any person engaged in commerce ... to lease or make a sale or contract for sale of goods ... where the effect of such lease, sale, or contract for sale ... may be to substantially lessen competition or tend to create a monopoly in any line of commerce.” 15 U.S.C. § 14. The district court relied on this court’s decision in
Black Gold, Ltd. v. Rockwool Industries, Inc.,
Smith strenuously argues that an actual contract for sale did exist between Hesston and itself at the time Hesston attempted to enforce the line-requirement provision of the distributorship agreement. In reality, however, what existed between the two parties at that time was not a contract for sale of the “tied” goods (i.e. *1299 the tractors), but rather a general distributorship agreement obliging Smith to carry a representative line of Hesston products. Smith refused to purchase any of the tractors. Thus, no purchase order for the tractors, which would have constituted a sales contract, was ever executed by either party. A mere franchise agreement, defining general terms and obligations of the relationship, does not rise to the level of an executed contract for sale as required by section 3.
This result may seem at odds with the purposes underlying the antitrust laws considering, as Smith argues, that a person would need to engage in “unlawful” sales in order to invoke the protection of section 3. However, as noted in
Black Gold,
AFFIRMED.
Notes
. Allegedly, the new dealer was required to take three tractors the first year, six tractors the second year, and nine tractors the third year. According to a Hesston sales contract, a dealer would be required to pay for a tractor nine months after shiрment, although Hesston maintains that it extended these terms to assist dealers not able to make a timely payment.
. N.M.Stat.Ann. § 57-1-1 provides that ‘‘[e]very contract, agreement, combination or conspiracy *1293 in restraint of trade or commerce, any part of which trade or commerce is within this state, is unlawful.”
. Smith’s assertion of stare decisis in the preclusion context is misplaced since that doctrine goes to the precedential value of a prior determination, and not to the narrow inquiry of whether a party is precluded from relitigating an issue.
Cf. Stevenson v. Sears, Roebuck & Co.,
. On appeal, Smith doеs point to deposition testimony in the record by a Hesston vice-president who admitted testifying in an unrelated trial that he was sure some dealers took on Hesston tractors under threat of termination, although he had no personal knowledge of such an occurrence. The vice-president also had admitted that Hesston had a policy of terminating dealers that refused to stock the tractors if a replacement dealer in the area could be found.
. In this particular case, the alleged line forcing might better be termed a vertical "arrangement” rather than "restraint” since Smith was not prohibited from carrying the product lines of competitors as it would be under an exclusive dealing arrangement, the classic "vertical restraint." Smith was “restrained,” however, in the sense that it was obligated to carry a representative line of Hesston products and it could not refuse to do so without violating the terms of the distributorship contract. A “horizontal restraint,” on the other hand, represents “an agreement among competitors on the way in which they will compete with one another” and is often held to be unreasonable as a matter of law.
